WINE-GLASS, BLUE GLASS CASED OVER
GLASS, with ACID-ETCHED DECORATION
Benjamin Richardson, England, 1857
I It. 143 mm (563 in.)
Acid Etching: Although acid-etched glasses
arc known to exist from the 17th century,
the process was not generally used in glass-
making until the 19th century, with the
discovery of hydrofluoric acid. Heinrich
Schwanhardt (d.1693), son of the Nurem-
berg engraver Georg Schwanhardt, is
recorded to have engraved glasses with
acid, one example attributed to him being
dated 1686. The technique can be used
either to cut through one layer of glass to
another, as in the glass illustrated, or to
provide a single-layered glass with a matt
finish. An acid-resist such as wax paraffin
covers the parts that are not to be affected,
the pattern having been cut through the
resist. The surface of the glass is then
treated in an acid bath (such as a mixture
of 100 parts of water, 10 of potassium
fluoride and t part hydrochloric acid).
Benjamin Richardson of the Richardson
firm of Stourbridge took out a patent to
etch glasses in 1857.
VASE WITH ACID-ETCHED DECORATION
J. & J. Northwood, England, r.1878.
Ht. 216 mm (85 in.)
It was only in the 19th and 20th centuries
that acid-etching became at all an accepted
mode of decoration. In England it is
known that the Dudley firm of Thomas
Hawkes used the technique in the 1830’s.
Besides flat glass objects, wine-glasses,
bottles and vases were being acid-etched
by the 1840’s. John Northwood and T.
Guest were involved in the Richardson
experiments with acid-etching, and in the
186o’s established themselves as individual
firms specialising in etching. They were
known as J. 8c J. Northwood, and Guest
Brothers respectively, and produced a
quantity of etched work in the later 1860’s
and 1870V The skill and delicacy of the
etching they achieved can be seen on the
vase illustrated, made at the J. 8c J.
Northwood works and shown at the Paris
Exhibition of 1878. Acid-etching was by
no means a technique confined to England,
however.
The Techniques of’Taking Away
As Maurice Marinoi of Trance grew to
understand the nature and working of
glass, he experimented with its ornamen-
tation. In 1922 he began using the
technique of acid-etching in a manner
distinctly his own. The process had been
used by French glass-makers since the
mid-19th century. F.mile Galle, comment-
ing on the technique, had said that it would
not do for delicate work, but ‘it cuts into
certain glasses in a manner of its own’. He
used it in his factory from 1890 onwards,
and the Daum factory had also used it to
some extent. Marinot took up acid-etching
because it suited his purpose better than
any other decorative technique. When he
employed acid-etching he used the massi v e
forms he had always favoured, in trans-
parent, occasionally tinted, glass. The
etched designs cut deeply into the surface,
giving an almost sculptural look to the
glass. The whole surface of the glass was
subjected to the treatment, with the most
varied results.
Acid-etching has been used to give a matt
surface to the colourless glass vase illus-
trated. This slender vase has a round foot,
w ith a long stem widening slightly towards
the bowl, which is of an exaggerated tulip
shape. It is just one example of the beaut]
of modern Swedish glass. Even such an
aesthetically difficult technique as etching
has been triumphantly used to give .1
beautiful all-over textural and eye-catch-
ing finish. It has been said that ‘Sweden’s
great contribution to modern design was
to transform Functionalism from an in-
tellectual theory into a practical instru-
ment for better living’ (Polak, 1962). This
was eminently shown in her glass-making;
but besides qualities like fitness for prac-
tical purpose, toughness in wear and
cheapness of production, the general aim
from the beginning was to create objects
of beauty. The Swedes succeeded in their
glassware perhaps more than in any other
branch of modern design.
ENGRAVED AND SAND-BLASTED VASE
Hy Sverre FtTterscn, Hadeland, Norway, 1038
Sand-blasling: In the process of sand-
blasting a stream of sand, crushed flint or
powdered iron is directed on to the surface
of the glass in a jet of air. The parts of the
glass to be left plain are covered with a
stencil plate of steel, or an elastic varnish
or rubber solution painted on to form a
protective shield. The type of finish is
varied by altering the size of the nozzle, or
the abrasive, or the air pressure. The
technique has been in use since 1870,
though it has rarely been applied to vessel
glass, except for lettering on mass-pro-
duced items, and is mainly used on glass
panels for decorative architectural use.
One of the more successful uses of sand-
blasting on vessel glass was by Sverre
Pettersen of Norway (1884-1959), who
was engaged as designer to Hadelands
Cilasswerk in 1928—at that time the only
factory for table glass and decorative glass
in Norway. During the ‘thirties he pro-
duced some very interesting pieces with
sand-blasted decoration.
PLATE WITH SAND-BLASTED ENGRAVING
By I adislav Oliva, Czechoslovakia, 1959
Diam. 362 mm (1425 in,)
Such are the difficulties attached to using
sand-blasting for anything but the heaviest
surface decoration that only very occasion-
ally are satisfying examples of the tech-
nique to be found. One of the exceptions is
this plate, designed and executed by
Ladislav Oliva (b. 1933) in Czechoslovakia.
The plate, in clear colourless lead crystal
glass, has a slightly raised rim, and the
grille-like decoration is in the form of cuts
about to mm (4/ioths in.) deep. Oliva
manages through this technique to give
the glass a new and exciting appearance.
His decorative themes always seem to
result from the natural lights of the heavy
glass mass. The matt finish that sand-
blasting imports to the glass can be very
pleasant to the touch, although sometimes
it can give a fairly rough effect.
The  century has been called the ‘golden
age of glass”, for it added many new tech-
niques to the glass-maker’s repertoire. This
sudden burst of activity can be put down to
many factors, including ‘the industrial revo-
lution, the relaxation of government controls
on the industry (specifically in England) and
a pride of craftsmanship born of freedom’
I Revi, i<)5g). Not since the Italian Renais-
sance had there been such an interest in new
glass-making ideas. In America the larger
firms hired scientists to discover new methods
of colouring glass, one of the best-known
being the Englishman Joseph I^ocke. In
Britain and on the Continent there was keen
rivalry in producing new types of art glass
for a highly competitive market. Demand
rem lied its zenith towards the end of the
I ii torian era. Since then, though new
techniques have still greatly interested glass-
makers, the art glass produced has reflected
the inherent qualities of the material, rather
than added decorative effects.
Pearl Satinglass, also known as Pearl Ware,
Mother-of-Pearl Satinglass and Verre de
Soie, can be found in a variety of patterns
and colours, but basically it shows the
technique of keeping a symmetrical or
controlled pattern of air traps within the
body of a vessel. The vase illustrated shows
a typical example in the so-called hobnail
pattern. Benjamin Richardson of England
filed the first patent for this technique in
1857. His method was quite simple. A
gather of glass was blown into a mould
which carried the pattern in projected
form. The piece, thus indented, was
covered by a further gather of glass, which
caused air traps to form over the pattern.
Another method current in England and
America in the late 19th century was to line
a heated mould with glass tubes, either
clear and colourless or coloured, and to
blow a bubble of glass into this mould.

LAYER

The tubes would thus be caught up and
marvered into the body of the glass. By
twisting the paraison the worker produced
articles of glass with pearly swirled stripes
on the outer surface. This method was
probably used to produce the body of the
bowl illustrated, which has been further
worked to form a frilly rim, and has the
heavy applied decoration current around
1885, Patents to produce Pearl Satinglass
were filed by firms in New York in 1881
and France in 1885. The Mt. Washington
Glass Company of the U.S.A. filed patents
in 1886, which also suggested using heat-
sensitive metal to colour the glass, and
giving the article a lustreless finish by
using an acid bath, or by sand-blasting.
The Phoenix Glass Company of Pennsyl-
vania filed patents in 1886, 1887 and 1888;
the final patent described the use of two
moulds, one to pattern the inner wall of
the article, the other to be used after the
outer casing of glass had been applied.

The finished product made by the tech-
nique last described displayed a criss-
crossed network of pearly-indented lines
contained in the body of the article.
William Webb Boulton, who had the
Audnam Bank glass-house in England,
filed a patent for Pearl Satin Glass in 1885.
Other English glass-houses manufactured
this type of glass, notably Stevens &
Williams of Brierley Hill, who called it
‘Verre de Soie\ Much of the Pearl Satin-
glass produced in the late 19th century
came from Bohemian and French factories.
These cheaper wares, supplied by factories
at Steinschonau and Altrohlau, Bohemia,
effectively ruined the market for the finer
wares of England and America. Many
different means were used to colour Pearl
Satinglass. The rainbow striping suggested
in this fairy lamp was produced by laying
coloured rods of glass on the body of the
article before it was fully formed.
VASE IN PEARL SATINGLASS
Thomas Webb & Sons, England, probably early
iSoo’s. Hi. 260 mm (1025 in.)
The technical development of trapping air
in moulded recesses between an opaque-
glass body and a tinted layer was further
refined by Thomas Webb & Sons of
England. In the magnificent example
illustrated the vase has a diamond air-lock
pattern between opaque and translucent
layers of glass, but has been covered by an
outer layer etched away to form a floral
pattern in relief; the whole article has a
satin finish. In 1889 Thomas Webb
patented this process for manufacturing
cameo relief designs on articles of Pearl
Satin Ware. After the diamond air lock
pattern had been produced in the usual
way, an extra coating of opaque white or
coloured glass was applied. The design
was painted on to this coating with acid-
resisting inks; when the article was plunged
into an acid bath, the acid dissolved away
all glass not protected by the resist. The
glass-maker had to be extremely careful
not ti) leave the object in the acid too long,
lest the acid reached the air traps.
FOOTED VASE, WITH CORAIE1NE DECOR AI ION
Last quarter of iqih century. 111. 127 mm (j in.)
Corulene: ‘The vase illustrated displays a
type of decoration that became popular
from its introduction in the last quarter of
the 19th century and is known as
‘Coralcne’. A design was painted in enamel
on the surface of a glass. Tiny glass beads,
which could be clear, coloured or opales-
cent, were then applied and stuck to the
enamel paint of the design. The object was
next put into a muffle-kiln, where the
enamel and beads were fired firmly into
place. Decoration could be in the shape of
coral, but is also seen in fleur-de-lis,
herringbone, sheaf of wheat and many-
other patterns. This type of decoration is
found in all colours and on all types of
glassware. Coralenc was so named by the
Mt. Washington Glass Company in the
U.S.A., and by several Continental and
English glass manufacturers. Its use was
not restricted to any one factory.
Amberina is generally recognised as a
clear amber glass shading to red at the top.
The patent for it, dated July 24, 1883, was
granted to Joseph Locke of the Libbey
Glass Company. This remarkable man was
born in Worcester, Kngland, in 1846 and
worked first as a potter. Guest Brothers of
Stourbridge, etchers and decorators of
glass, engaged him, but later he was
persuaded to join the firm of Hodgetts,
Richardson & Company, where he pro-
duced his copy of the Portland vase. After
various employments, Locke finally went
to America in 1882, where he was signed
on by the New Kngland Glass Company
of Cambridge, Mass., later to become the
Libbey Glass Company of Toledo, Ohio.
‘Amberina’, ‘Pomona’, and ‘Agata’ glass
are only a few of his achievements while in
their employment. Amberina was the first
patented method for producing shaded
and parti-coloured glassware from a sen-
sitive homogeneous metal.
To produce Amberina a very small amount
of gold in solution was colloidally dis-
persed in a transparent amber glass metal.
When an object had been made from this
mix, it was allowed to cool below a glowing
red heat and then certain parts were re-
heated at the ‘glory hole’ (a small opening
in the furnace). This caused a red colour to
strike in the reheated portions—but over-
firing caused a fuchsia or purple shading.
Further patents were issued either to
Locke or to Kdward D. Libbey. An
interesting development was the produc-
tion of blanks composed of sensitive
Amberina glass which, after moulding,
were reheated to produce a deep ruby
colour on the outer surface only. A design
would be cut through to the undeveloped
amber colour below, giving a rich effect.
Amberina was made in Cambridge, Mass.,
between 1883 and 1888 by the New
Kngland Glass Company. A fine though
short-lived revival was made between 1917
and 1920, when the firm had moved to
Toledo, Ohio; one of its products is
shown above.
New England Glass Company, U.S.A., 1886
Ht. 178 mm (7 in.)
Almost every glass company in Europe and
America probably made Amberina at some
time during this period. A new technique
was patented for the New England Glass
Company in 1883 and was called ‘Plated
Amberina’; this was unique to that firm.
A piece of opal or opalescent glass plated
with a gold-ruby mixture was reheated at
the ‘glory hole’, so that it would develop
deeper and lighter shadings on its outer
surface. When Amberina metal was used,
the shading would of course be amber-to-
red. However, other colours could be
made: a sensitive cobalt and ruby glass
mixture would produce a plated ware
shading from blue to ruby. Canary, blue
and green colours were also mentioned in
the patent. Plated Amberina invariably has
moulded ribbed decoration, as in the
example shown, though this had no par-
ticular bearing on the specifications men-
tioned in the patent. It was manufactured
only from 1883 to 1886.

Ml Washington Glass Company, U.S.A., 1886
Ht. 127 mm (5 in.)
The Mt. Washington Glass Company,
New Bedford, Mass., attempted more or
less successfully to produce its own
Amberina glass under the name ‘Rose
Amber’. This was in every way similar to
Locke’s Amberina. Needless to say, the
New England Glass Company had an
injunction granted in 1886 in their suit
against the Mt. Washington Glass Com-
pany for infringement of their patent.
The Circuit Court of the United States
forbade the New Bedford firm to produce
its Rose Amber wares. However, it did not
seem that this injunction had any effect.
The New Bedford Board of Trade Report
of 1889 describes the making of Amberina,
Rose Amber, by ‘two companies, of which
the Mt. Washington was one’, and de-
scribes how ‘it caught the popular fancy
and was all the rage for about two years’.
According to this report it was the success
of the Amberina glass that caused Mt.
Washington to go in for an opaque shaded
ware—Burmese glass.

Quite a number of Amberina pieces were
pressed or press-moulded. This piece can
definitely be attributed to the New Eng-
land Glass Company, since it follows a
design sketch made by Joseph Locke in
1884 when he was head designer for the
Cambridge winks. I lobbs Brockunier &
Company of Wheeling, West Virginia,
were licensed to manufacture pressed
Amberina by the New England Glass
Company in 1886. Sowerby’s Ellison Glass
Works Ltd., Gateshead-on-Tyne, Eng-
land, were also licensed to produce pressed
Amberina in 1883. A transparent, homo-
geneous glass shading from pale amber to
a delicate rose tint was press-moulded by
the firm of CristalletICS de Baccarat of
France from 1916. Known as ‘Rose Teinte’,
or to collectors as ‘Baccarat’s Amberina’,
it was reintroduced in 1940 as a popular
item. Its delicate colours were a result of
using less gold salts in the glass, but its
similarity to the American Amberina and
Rose Amber is undisputed.
‘Alexandrite’ glass, a single-layer glass of
three blended colours, first appeared about
1900, and is reputed to have been made by
the two English firms of Thomas Webb &
Sons and Stevens & Williams. 11 started off
as an amber glass; a portion would be re-
heated to rose, and reheated again to blue
on the outer rim, producing an exception-
ally beautiful effect. It is found in plain as
well as patterned surfaces. Stevens &
Williams used a differing technique to
produce the same effect. They cased a body
glass of transparent amber with rose and
blue glass. The outer casings of blue and
rose were then cut away, to reveal the
yellow glass beneath. Kolo Moser, a glass
designer of Bohemia of the early 1900’s,
produced an amethyst transparent glass
which carries the mark ‘Alexandria, but
this one-colour ware should not be con-
fused with the work attributed earlier to
Webb and Stevens & Williams.
PITCHER IN RUBY GLASS WITH DEVELOPED
OPALESCENT DESIGN
I hi i ijih century. I It. 279 mm (11 in.)
Opalescent Glass: In the late 19th century
glasses with raised opalescent white de-
signs became very popular. A coloured
gather of glass was heavily coated with a
sensitive, clear colourless glass containing
bone ash and arsenic. This was blown into
a patterned mould to give it the raised
design. It was then cooled slightly and
reheated, the raised parts striking an
opalescent white, while the background
retained the original colour. Inexpensive
glassware in this technique was produced
by Hobbs Brockunier & Company of
Wheeling, West Virginia; Alexander J.
Beatty & Sons of Steubenville, Ohio;
Phillip Arbogast of Pittsburgh, Pennsyl-
vania ; John Bryce & Company of Pitts-
burgh ; King & Company of Pittsburgh;
and Doyle & Company of Pittsburgh, and
others. Thomas Davidson of George
Davidson & Company Ltd. the Teams
Glass Works, Gateshead-on-Tyne, Eng-
land, patented in 1889 a process for making
a pressed, shaded version, in which the
opalescence was either white or of the
same shade as the body metal.
VASE IN BURMESE GLASS
Ml. Washington Glass Company, U.S.A., 1885
Ht. 305 mm (12 in.)
‘Burmese’ glass is a single-layered glass
shading from opaque greenish-yellow to
deep pink at the top. It was developed by
the Mt. Washington Glass Company,
New Bedford, Mass. Frederick S. Shirley
patented his formula for Burmese in 1885
for the firm. He produced the glass by
adding small amounts of fluorspar, feldspar
and oxide of uranium to essentially the
same ingredients as used by Joseph Locke
to make his Amberina glass. The fluorspar
and feldspar gave the glass its translucency,
and the uranium oxide made the ordin-
arily translucent white glass melt a pale-
yellow in colour; the gold made the glass
sensitive to thermal changes so that when
reheated at the ‘glory hole’ it struck a
salmon pink colour, which shaded down
to the original yellow. A second reheating
caused the pink glass to revert back to its
yellow colour, a feature quite often seen
on the rim of a piece of Burmese glass.
Frederick Shirley’s formula for Burmese-
glass was patented in England in 1886.
Thomas Webb 8i Sons of Stourbridge,
England, purchased a licence to copy-
Burmese products as well as to produce
their own shapes and designs. Most ol t he-
English Burmese ware is acid-finished,
though Mt. Washington produced both
glossy and acid-finished Burmese ware.
Thomas Webb & Sons called their glass
‘Queen’s Burmese Ware’. The glass was
much used for the patent ‘fairy lights’ or
small individual candle shades so popular
in England and America in the late
‘eighties. Queen Victoria ordered a tea-set
in Burmese glass from the Mt. Washington
Glass Company, enamelled with what was
to become known as the ‘Queen’s’ design.
The ornamentation of Burmese ware was
often of a highly decorative order. Verses
by well-known poets, Egyptian scenes, and
bird and animal portrayals were included
in enamelled motifs. Occasionally, finely
wrought applied decoration w ould be used.
Peach Blow: When a ‘Peach Bloom’
coloured Chinese porcelain vase was sold
for $18,000 in 1886, this caused such a
sensation that products labelled ‘Peach
Bloom’ or —slightly changed ‘Peach
Blow’ attracted many sales. ‘The glaze on
the vase was described as being the colour
of ‘crushed strawberries’. The magic of
the name attracted the attention of manu-
facturers of coloured art glasses, who tried
to devise new types suitable for this name.
Hobbs Brockunicr & Company of Wheel-
ing, West Virginia, produced such a glass
and called it ‘Wheeling Peach Blow’.
Replicas of the ‘Morgan’ vase were made,
like the example illustrated, in both glossy
and acid finishes. The moulded Stand with
its five-headed griffin is in an unimportant-
quality amber glass, hut the vase itself is
made of white opal glass plated with 1
transparent amber glass, made heat-sensi-
tive with gold salts. Reheating caused the
glass to strike a ruby colour, shading to
yellow or amber.
The Mt. Washington Glass Company
filed trade-name papers on the terms
‘Peach Blow’ and ‘Peach Skin’ through
Frederick S. Shirley in 1886. As a
colourant for their new products Shirley
substituted a small amount of cobalt or
copper oxide, instead of oxide of uranium
as in making Burmese. This produced a
homogeneous glass shaded pale grey-blue
to a delicate rose tint in the reheated
portions. When plunged in acid the surface
acquired an all-over slightly grey cast. As
it is a single-layered glass, the shading is
the same on the inside as on the exterior.
The Mt. Washington Peach Blow wares
were manufactured in similar shapes to
their Burmese ware. Moulded and applied
decoration were used, as well as gilding
and enamelling. The example illustrated
shows the ‘Queen’s’ design, as ordered by
Queen Victoria from the firm. The pattern
is of conventionalised flowers in raised
enamel, much of the decoration done in
pure gold reduced with acids.
The success of its Amberina glasses caused
the New England Glass Company to
experiment further with heat-sensitive
glasses. One of the resulting products was
patented by Edward D. Libbey in 1886
and called at first ‘Wild Rose’, later ‘Peach
Blow’. It is a single-layered glass shading
down from red to white in the lower part
of the piece. To produce it, an opal glass
was combined with a gold-ruby glass in
one pot. When a vessel had been formed,
reheating produced the rose colouring in
the required parts. Glasses made from this
metal were moulded, decorated with gild-
ing and enamelling and also acidized to a
satin finish. Occasionally, they would be
left in the original glossy state. The vase
illustrated was decorated by Joseph Locke
for his daughter Nora. The etched reliel
designs covering the surface of the glass
have been outlined and highlighted with
gold traceries and a dark brown mineral
stain.
At about the same time that the U.S.A.
glass-making firms were experimenting
with heat-sensitive glasses, both Thomas
Webb & Sons and Stevens & Williams of
England manufactured shaded wares
which they termed ‘Peach Glass’ or ‘Peach
Bloom’. Webb’s Peach Glass was cased,
the inner layer being creamy coloured with
a slight ly greenish cast in the upper portion.
It is similar in appearance to Hobbs
Brockunier & Company’s ‘Wheeling Peach
Blow’. Stevens & Williams of Stourbridge
produced a glass called ‘Peach Bloom’
which was also very much the same in
appearance. The English Peach glasses
were produced in both glossy and acid
finishes, and arc frequently found with
elaborate gold decoration on both finishes.
Occasionally, Webb’s Peach Glass will
have the Webb incised mark on the base;
Stevens & Williams ware also sometimes
bears a mark under the foot.
The Boston & Sandwich Glass Company,
Sandwich, Mass., manufactured a glass
known as ‘Sandwich Peach Blow’. This
was a single-layered glass, strawberry ice
cream pink in shading, often found in
moulded and twisted swirl decoration; see
the example above, which also has the
characteristic thorn handle of the period.
Overlay decorations in a camphor or
greyish colour are quite usual, the com-
plete piece having an acid finish. Many-
other types of glass are loosely termed
‘Peach Blow’, but basically, apart from a
slight variation in colour shading, the
products can be summarised as follows:
Webb and Wheeling Peach Blow are
always lined, but Mt. Washington, New-
England and Sandwich Peach Blow are
never lined. The Bohemian manufacturers
soon cashed in on the vogue of Peach Blow
wares, producing far cheaper glasses,
which forced the better products off the
markets, though their wares in no way-
resembled those made in America and in
England.

Glass is distinguished from other materials by its transparency.
People like glass because of its shine and the way drinker.
glass refracts the light that passes through it. Glass is also extremely practical. It does not allow liquids to permeate it and is a poor conductor of heat. On the other side of course is glass’s only disadvantage — its fragility. Glass today is something modern humankind takes for granted. There is an involved process before glass objects reach the consumer.
Glass is formed by heating various metal oxides and quartz. In addition to the raw materials of glass (quartz and borax), there are also alkaline substances (potassium or sodium oxide). These make the silicates indissoluble.
The right composition of substances for glass is the result of centuries of experience. Glass was probably first made about 4,000 years ago — perhaps discovered in ancient Egypt by chance.
The production of glass was then a relatively straightforward process. The glass-makers first smelted glass in earthenware vessels over an open fire. The glowing pieces of glass adhered together and were then plunged into cold water where they splintered.
These shards of glass-like material were known as frit. The frit was then ground between millstones under powdered when it was smelted once more to achieve the desired result.
This principle was in use until some time after 1500. Old illustrations often show two glass furnaces: one is for the initial smelting of the raw materials and the second for melting the powdered frit.
The production of glass was changed in the eighteenth century in Britain. Coal replaced wood for the glass furnace but this turned the glass yellow from the sulphur dioxide that is released. This meant that glass had to be smelted in a sealed kiln.
This also made it more difficult to keep an eye on the smelting process. A solution was found by producing softer glass mixtures.
Means of decoration
Glass can be decorated in a number of ways. The most direct method is to apply layers of other glass or to mark the surface during the glassblowing process while the glass is soft. Such results depend on the skill and artistry of the glassblower. Glass has been blown since early times and had reached a state of high art in Roman times.
There are various waysin which glass can be decorated during blowing. One way is to add small pieces of glass or `prunts’. Another way is to spin the glass of the same or contrasting colour so that it forms a spiral on the glass surface. Many of the varying techniques are based upon centuries old traditions.
An entirely different way of decorating glass is to enamel or paint it.
This technique does not rely on the artistry of the glassblower. This is done with either ‘cold’ or fired enamel. Glass can also be gilded with precious metals such as silver or gold. Further ways of decorating glass are by cutting or engraving it. Glass is engraved with a diamond which ‘draws’ a design on its surface and it can also be stippled (a Dutch invention) with either a diamond or softer stylus.
Different effects can be created by making either open or dense stipple marks.
Glass has been cut since early times but etching was discovered by the Swede Sheele who notice that the acidic gases of hydrogen fluoride ate in to glass. Glass can also be ‘etched’ by sand-blasting. Encapsulation is done by placing objects in glass while it is still soft that then become fixed in the solid glass. This method was especially popular in Europe between 1800 and 1850.
Glass production from east to west
The production of glass spread to other countries from Egypt around 1000 BC. The techniques were extensively improved between the sixth and second centuries before Christ.
A very important discovery was made at Sidon in Syria in the first century before Christ – the glassblower’s ‘blowing iron’.
This enabled objects to be made of thin glass. It was a technique that spread throughout the Roman empire to Italy and Spain to the west but also to Gaul (France), Britain, and Germany in the north. The major glassblowing centres were established along the Rhine and in Gaul (France).
Production in the east
In common with many other techniques, glass-making was also largely forgotten following the fall of the Roman empire but this was not true in the east. The most important glass-producing region was Byzantium where new techniques were also developed that can be seen in cut and engraved goblets, bottles, ewers, and mosaics of the era.
Arabs were extremely fond of glass embellished with gilt or enamel and major Arab glass centres were Damascus and Aleppo in Syria.
Very fine coloured glass goblets, bottles, ewers, lamps, and dishes were made in these towns between the twelfth and fifteenth centuries. These were often decorated with bright painting.
Persian glass-making took over the leading position in the fifteenth century and Persian glass even influenced Spanish glass. Surviving Persian glass from this era consists mainly of bottles of green or blue glass.
Medieval European glass
Glass production in the former western Roman empire after its fall only survived in Gaul (France), Germany, Flanders, and Britain.
In the early Middle Ages the preference was for decoration with grooves, flattening, and decoration with ‘threads’
of glass. Several new types of object appeared such as `trunked’ and ’studded’ beakers. Otherwise just simple medicine bottles were made from green glass that was far from perfect.
Glass production even went into decline in the ninth century and many in Christian countries regarded glass as a heathen product. After all the heathens used bottles for their ‘pagan’ burials. Pope Leo IV even banned the liturgical use of glass. Not everyone was of the same opinion.
Bishop Isidorus of Seville in Spain wrote a treatise about glass based on Naturalis Historiae, written by the Roman Plinius. The monk Theophilus wrote an extremely important work about glass —probably during the late tenth or early eleventh century, somewhere along the Rhine.
In a piece about the art of glass he described the constituents of Roman and Asian glass, wrote down many legends, and described the process of glassblowing in great detail.
Venice
Sometime around the birth of Christ, glass was produced in northern Italy. The technique was maintained by cloistered orders and spread from these during the Middle Ages throughout Europe. It was in this region that the one of the most famous glass-making centres was established.
Benedictine monks in Venice specialised in making bottles by the year 1000. Following the conquest and pillage of Constantinople by the crusaders in 1204, many Byzantine glassblowers sought to escape to the powerful trading city of Venice.
They strengthened Venetian glass-making with techniques such as glass mosaics. The first thin and hollow glass-ware and first glass jewellery were made in Venice in about 1250. Soon afterwards the production of glass became a monopoly of the Venetian state. The glassblowing works though were forced to move outside the city. With their extensive use of fire they threatened the safety of the city and hence were moved to the island of Murano.
The first reports of exports of glass from Venice are also recorded around 1250. They also made optical glass for spectacles and window glass.
A great deal of glass incorporating soda from burnt seaweed was made in the fourteenth century. The Venetians also began to make latticinio glass with thin white threads around 1400. The Venetians were also known to make golden coloured glass by chemical means and other colours too with copper and cobalt.
They also decorated their glass by `burning’ colours into it. This is very characteristic of fifteenth century Venetian glass. In the sixteenth century the Venetians mainly decorated their glass with patterns of opaque white threads. Vegetal and abstract designs were also created on the thin-walled soda glass.
In addition to clear cristallo glass, Venice also made opaque white lattimo glass that was translucent but not transparent, millefiori containing tiny rods of coloured glass, and frosted glass with a cracked surface. The glassblowers also produced all manner of decorative forms with glass. The chemical composition of Venetian glass was a secret with severe penalties for anyone who revealed the procedures to make it. Despite this, many Venetian glassblowers left for other parts in the early sixteenth century and became involved abroad in the production of imitations of Venetian glass. Excellent copies of glass d la facon de Venice were made in Spain, France, and the Low Countries. These are so good that it is very difficult to determine whether a piece is made in Venice or elsewhere. The main differentiation is that the metal (body of the glass) of the imitations is not so clear, fine, and thin as that produced on the Venetian island of Murano.
Developments elsewhere in Europe
In Bohemia and Germany they also tried to join in Venice’s success. The glass works there only flourished after the Middle Ages. Many attempts were made in France employing Italian immigrants to make totally transparent and clear glass. Dutch glass makers began to make diamond engraved fluted glasses in the sixteenth and seventeenth centuries and it was the Low Countries too that made glasses with a characteristic ‘winged foot’. It was also quite common for glass made in one place to be decorated elsewhere.
BOHEMIAN AND GERMAN FOREST GLASS
The extensive forests of Bavaria were home to many glass works. The production area lay within an area bordered by the Thuringia and Bavarian forests, and the Alps and Fichtel mountains. Because of iron and potash in the raw materials the glass produced was mainly green.
New types of glassware were created that were primarily functional with the main output being glass beakers but ink pots and alchemists’ and apothecaries’ jars were also made.
This was often decorated with prunts and molten threads of glass. Glass was also decorated with bizarre relief forms. All these products were small icrean size in the fourteenth and fifteenth century. Larger pieces were noss bt made until the sixteenth century.
The most widespread of these are so maigelein: shallow beakers of blown gas

of which the bottom is pressed inwards. There were also much larger Pasglas measured glasses, beakers in the form of cabbage stalk, beakers with finger grips, and vertically ribbed cylindrical beakers. The classical slim and tall beakers of Bohemian glass were made in the fourteenth and fifteenth centuries. Their small stems are externally decorated with prunts of molten glass. The Romer glass was first made in the fifteenth century. These wine glasses were extraordinarily popular in the Rhineland. A bellied glass, shaped like an onion with a curved neck consisting of several plaited tubes of glass also appeared in Bohemia in the late Middle Ages.
ENAMELLING
Every glass works outside Italy strived to improve on Italian glass with their local products but the shape of their glassware is clearly different from that of Renaissance Italy. This is because of different local drinking customs. Wine was drunk in Italy but north of the Alps people mainly drank beer. This caused different demands of glasses. The Humpen beer glasses were made from the middle of the sixteenth century.
At first these were conical in form but later only cylindrical Humpen were made. This latter type had a low sole and sometimes also had a hinged lid. The style of painting was intended to give the impression of an Italian product and this also helped to mask the imperfections in the glass.
Enamelling was commonplace on sixteenth century central European glass. The best period for this form of decoration was reached in the earlier seventeenth century. The quality of glass was then improved through the addition of chemicals.
Another category of glassware was the beakers that bore the owner’s crest of arms.
These were also monogrammed and dated. Others, known as ’state eagle’ Humpen were decorated with the German state arms. Quite separate from these glasses though were the Fichtel mountain ox-head glasses that were painted with pictures of the wooded hills from which the Eger, Main, Naa, and Saale rivers rise. Old and New Testament references, fables, and allegories were also common painted decorations in both the Renaissance and Baroque eras.
Although enamelled glass originally came from Venice it gradually became the speciality of central Europe. This method of decoration was used for more than 250 years.
Spun stem Dutch glass. Spinning a thread of glass of the same or contrasting colour around a glass core is one method of decoration.
Enamel became less expensive in the later seventeenth century so that ‘ordinary’ citizens were able to buy it. Finally it became a product for the masses and when applied to milchglass became a cheap alternative to porcelain.
Finding out the origins of a piece is no easy matter. There are countless different types with regional and local characteristics but these became less pronounced as glassblowers moved to work at different places.
PAINTED TRANSPARENT GLASS
A new manner of decorating hollow glass objects was introduced in the later eighteenth century using transparent enamels instead of opaque ones. The porcelain artist Samuel Mohn of Dresden was the first to use this technique.
His ‘friendship’ glasses are painted with portraits, landscapes, allegories, and verses. He customarily signed his work with Mohn fecit. His son, Gottlob Mohn, established himself in Vienna in 1811 and signed himself G. Mohn in Wien. His first work was the painting of town views.
The Viennese porcelain and glass artist Hothgasser took up this popular subject, working mainly on bell-shaped glasses on long branched stems. He mainly signed his work with his monogram between the ‘teeth’ of the branched stem.
Sometimes though he used his full signature on his glasses. These were given as a present or friendship’s token, or served as souvenir. Kothgasser’s glasses with playing cards were very popular around 1875. Kothgasser’s work was in great demand and hence widely copied but reproductions are easily spotted by the naive compositions and lack of technique.
BOHEMIAN ENGRAVED GLASS
The process of engraving was already known during Roman times but the ancient technique was re-invigorated during the sixteenth century in southern German with fresh demand for this style of decoration. This arose because of exports of engraved crystal from Milan. The so-called ‘mountain’ crystal was rare and hence expensive. This led to people in southern Germany deciding to apply the decorative technique used with crystal on glass. Lehmann One of the most famous engravers is
Kasper Lehmann, engraver to the court at Prague. Until recently he was even deemed to have been the ‘inventor’ or glass engraving.
Engraved ginger glass, circa 1700. Although known since Roman times, it was not re-introduced until the 16th century, in southern Germany. Engraved glass became very popular in the north of the Low
Countries.
He established himself in Prague around 1600 and in 1609 he gained a monopoly from the king for the engraving of glass. Lehmann had a number of students, including Georg Schwanhardt, the most important of them, who returned to his home town of Nuremberg following Lehmann’s death. There were many engravers working in this town but each had his own area of speciality.
Schwanhardt mainly worked with Venetian-type goblets, although Venetian glass itself is not suitable for engraving because it is too fragile. Glass with lime added was used for engraving. This sparkling glass was clear and pure with strong refractory properties. It became known as Bohemian crystal.
Bohemian ‘crystal’ was discovered between 1670 and 1680 more or less simultaneously in three glashutten in southern and northern Bohemia. Knowledge of the process spread quickly throughout Bohemia.
Painting with enamel was depressed here by engraved Bohemian ‘crystal’. The first decorations were copies of motifs used in Venice. Because of the high quality of the new material it quickly became a formidable competitor for Venetian glass. Traders not only succeeded in selling Bohemian glass throughout Europe, it was also shipped to other parts of the world.
When the engraving switched to the Baroque style Bohemian glass was even more successful.
SILESIAN ENGRAVED GLASS
The successful formula of Bohemian glass works was also followed in Silesia. The works of Count Schaffgotsch were very important to this region. The glashut in Hermesdorf in particular produced some fine pieces. This was due to the engraver Friedrich Winter who engraved a series of friendship goblets and beakers there after 1690.
The engraved glass from the works at Lobkowitz in Wiesau and Warmbrunn were also of exceptionally high quality. Silesian glass is characterised by the narrowing at the bottom of the drinking vessel. Although Bohemian glass itself was of higher quality, the exceptional Silesian engraving was better than that of Bohemia.
Glass production was advanced following Prussia’s capture of Silesia from Austria in 1742. Glass production in Silesia and Bohemia began to become less significant in the mid eighteenth century due to a number of factors. These included a smaller market through European wars that had caused economic collapse and also a reduction in the size of the market through the development of porcelain and lead crystal. Superb glass goblets made way for simple beakers. Both form and decoration were simplified and more suited to the new circumstances.
The Bohemian glass industry searched for a way to emerge from the crisis.
One of their developments was milchglas that was supposed to compete with the rapidly growing market for porcelain. Entire sets of tableware and drinking services were produced from 1760 to the mid nineteenth century by works at Harrachov in Bohemia.
The opaque ‘milk glass’ was much cheaper than porcelain but could emulate it in both form an enamelled decoration.
GERMAN DEVELOPMENTS
The discovery of the addition of lime to forest or potash glass in Bohemia was also important for the German glashutten.
This was especially true of those works of the electors of Saxony and Brandenburg which bordered Bohemia. Silesian experience in both glass making and engraving was utilised at Brandenburg works at Potsdam, Berlin, and later also at Zechlin. Potsdam attracted Martin Winter, brother of the highly regarded Helmdorf engraver.
The glass specialist and alchemist Johann Kunckel was given the task of researching the best composition for glass. He is credited with discovery of Zwischengoldglas or ‘gold-ruby’ glass. Other gifted engravers also worked for Brandeburg glass makers in addition to Winter.
Glass from this time is solid and heavy. The foot or stem, drinking vessel, and lid were decorated with leaf motifs. Pieces were lighter after 1720 under the influence of the engraver Elias Rosbach. Zechlin glass though (which had gilt medallions melted into its surface) remained fairly robust.
Knowledge of how to produce Bohemian glass spread via Nuremberg northwards. Important centres were established at Brunswick and Hesse, while the glashutten of Thuringia were also important parts of the German glass industry. Just as with porcelain, the electors of Saxony also initiated establishment of glassworks in their domain.
The Saxon works copied Bohemia so precisely that their glassware closely resembles Bohemian glass. Saxon glass though uses slightly different forms, such as horizontal, diagonal, and faceted rims on the stem and underbelly of the bowl. There is a difference too in the gilded relief and gilded engraving
‘RUBY GOLD’ GLASS
In addition to engraved glass, Bohemian glass works also produced ‘ruby gold’ glass or Zwischengoldglas during the prime era for Baroque style. This type of glass had been known in Roman times but forgotten. Following its rediscovery by Johann Kunckel in Brandenburg, Bohemian glass makers also started to make it. The same type of decoration was employed as was used for Bohemian `crystal’.
This consisted of engraving, silver gilt or gilt leaf motifs placed between two layers of glass. Only a few pieces were double layered at that time.
English lead crystal and Dutch glass
Around 1750, glass that was stabilised with lead became important in Europe. The heavy lead ‘crystal’ was well adapted to practically-shaped pieces following
Painted glass box, circa 1850. This type of movingly painted glass boxes were made in Friesland in the Low Countries Classical lines. Lead crystal has unique properties.
It is absolutely clear and is decorated in an entirely different way. By use of a diamond cutting disc a large number of facets can be created that cause light refraction — acting as a series of prisms. Dutch glass was extensively engraved with diamond cutters and lead crystal became extremely popular there. After 1750, some exceptional Dutch pieces were made by stippling the glass with a diamond.
The solid goblets used for this purpose were partly imported from Britain.
Nineteenth century glass
Bohemian crystal found a strong competitor with English lead crystal cut glass. This was because the lead crystal was ideally suited to the forms of the fashion for Classicism. The Bohemian glass makers reacted by adopting the English cut-glass technique but Bohemian glass was not suitable for cutting. The consequences were therefore limited and the technique was restricted so that cutting remained solely an extension to engraving. The subjects for engraving were determined by the current fashion and this can be seen by the motifs used.
Count Georg Buquoy of Neugrdtzen in southern Bohemia became very taken with Wedgwood’s ‘Egyptian Black’. In common with Friedrich Egermann in Haida, Neugrdtzen began making black Hyalith glass that was mainly decorated in a golden chinoiserie style.
The wares included carafes, coffee services, dishes, and vases. Egermann created Lithyalin, a different form of opaque glass that resembled jasper and agate. Like these stones it could be facet cut. Egermann’s glass works also used a golden yellow glass paint that he invented. This was used on goblets and beakers from 1820. Egermann’s greatest achievement though was his contribution to the enriching of glass.
With the help of copper he was able to create cheap imitations of expensive
golden-coloured ruby glass. Glass makers sought an ever greater range of colours and forms for their wares. On the one hand they attempted to improve the process of applying coloured glass to a clear glass base while on the other they sought to develop new methods.
This led to a new technique in which several layers of coloured glass were applied to a base. It was a process that had originated in China. By cutting away parts of the different coloured layers, all manner of colour effects could be created. The use of several layers of milchglas was particularly popular. With this, when a pattern had been cut out it was further decorated with enamel.
Bohemian glass companies exported lots of this type of ware in the 1850’s. Around 1820 the Bohemian glassworks also made glass that was smelted with embedded plaster or porcelain with portraits of famous persons. From 1830 onwards the glass market changed radically because of the major changes in how glass was made. Until that time each piece was individually crafted by a glassblower. During the nineteenth century factories began to press mould glass. This process made it possible to mass produce glass making.
The artistic level of the output dropped of course but commercial considerations were generally more important than aesthetic ones. Very few managed to avoid this trend. One who did was the Viennese artist Ludwig Lobmeyr, who owned a quality glass making works in Steinsch6nau. He was one of a group of artists who opposed the levelling down and increasing lack of taste of the mass produced wares.
This group studied ancient and exotic forms of glass and this led to their works making new types of glassware with simple and functional shapes. Before this trend gained wider acceptance though it was consumed in an even more radical movement that swept Europe under the Art Nouveau and Jugendstil names. The artists A. Daum and E. GaI16 gave glass-making back its individual power of expression and returned to the old traditions. In the United States Louis Comfort Tiffany was inspired by oriental and classical glass. His work was widely admired and echoed in Europe.
One glass works that copied his lead was the Liitz works at Klostermiihle in Bohemia.
Glass and jewellery
Glass paste and beads were used for jewellery back in the age of the ancient Egyptians. Alexandria supplied the then known world with glass beads during the
ancient Greek civilisation and during the Roman empire. The strings of beads made with them were of different colours. The glass was decorated with wavy melted threads of lighter-coloured glass. The production of beads spread through Constantinople and the other towns of the Roman empire to Europe.
Venice was an important production centre for glass beads in the eleventh century. Imitation gem stones had been made in Bohemia as early as the fourteenth century. In the eighteenth century
Louis XIV style mirror of the 19th century.
They also started to make glass beads. Production of glass beads had started in the German Nuremberg in the sixteenth century followed by the Fichtel mountains area of Bavaria in the seventeenth century, and soon afterwards by Potsdam and Thuringia.
Bead production of importance got under way in France in the seventeenth century.

18th-19th Century Silver Entree Dishes and Sauceboats
Entree dishes and sauceboats were among the new items of dining silver introduced in France in the late 17th century. French fashion changed European tastes in food: as the new trend developed, the typical plain roast meat served with cold sauces was replaced by soups, stews, and dishes accompanied by hot sauces made from seafood or veal stock, ham and bacon, and herbs and spices. Silver was a particularly useful material for vessels containing these hot foods as it retains heat well. In the 18th century dishes and sauceboats were decorated en suite with plates, tureens and other dining utensils, as the complete dinner service with matching ornaments became the height of fashion.
SILVER ENTREE DISHES
Entree dishes were used for serving the “entree” – the first course of cooked food that came before the main meat course – for example, small game such as hare, pheasant, or partridge. From about the middle of the 18th century they were also known as “hash” or “curry dishes”, from the hot and spicy curries that were introduced to Britain via its extensive trade with India. Today, entree dishes are more popular for serving vegetables or salads.
Made in various sizes and often in pairs or sets of four, these dishes are shallow with a flat bottom and/or four low feet and usually a domed cover with a handle. As with candlesticks, single entree dishes are generally less collectable than a pair or set. The handles, which are sometimes wooden on early examples, are generally detachable, so that the cover can be used by itself as a separate dish. The cover should always fit comfortably into the dish, and both should bear the same marks. Some entree dishes had Sheffield-plate covers, possibly to reduce the cost of the whole piece.
Entree dishes from the mid- and late 18th century are usually oval in form, with a handle on the cover and very little ornament other than gadrooning or fluting around the edges. The finest entree dishes have heavy cast handles in the form of a family crest, but simple reeded or plain ring handles, with leaf decoration covering the locking plate, are more common. Most examples are also engraved with a coat of arms, but some pieces have a coat of arms on the cover and a crest on the base. Those made in the late 18th century tend to Lie much lighter than earlier ones, as the gauge of metal used was considerably thinner. Such pieces should therefore be carefully checked for denting or splitting.
In the early 19th century entree dishes became larger and heavier, with a more pronounced domed shape to the cover, and with ornate cast handles sometimes in the form of vegetables, reflecting the contemporary taste for naturalistic ornament. Shapes became more varied, being square, oblong, round, and cushion-like as well as oval. The simple gadrooning around the rims was often replaced by more elaborate reeding interspersed with flowers, scrolls, or shells.
To keep the food warm, the dish was generally placed either on a dish cross (incorporating a burner) or, from the early 19th century, on a plated heater base, usually made from Sheffield plate, which contained hot water or a block of heated iron. Only a very few entree dishes are found today with their original heater base.
Fewer dishes were being made for the entree course by the mid-19th century, principally because the custom of laying out dishes on the table so that diners could help themselves was replaced by the practice of servants serving food to each of the diners individually as they moved around the table.
SILVER SAUCEBOATS
First introduced c.1715, sauceboats were used for serving gravy or the rich, thick sauces that accompanied meat and fish dishes. They were often made in pairs, and sometimes in sets of four or six for larger services. Like other items commonly made in pair or sets, a single sauceboat is generally less desirable than a pair. The earliest examples of the George I period were double-lipped and stood on a flat oval base with simple scroll handles on either side of the body. The only decorative features were the moulded, wavy rim and engraved armorials. However, this form, which was copied by early European porcelain manufacturers, proved impractical for pouring, and by c.1725 the familiar bulbous form of sauceboat had appeared, with its single everted (out-turned) lip opposite a handle. It was first made with a central pedestal foot; three or four cast hoof, shell, or scroll feet were introduced in the 1740s, and cast masks or shells applied where the feet joined the body. Some sauceboats were made with a matching circular or oval stand and ladle and sometimes a cover.
The body of the sauceboat was generally raised from a single sheet of silver, so no seaming should be evident. For practical reasons, decoration was restricted to gadrooning or punching to strengthen the wavy rims and the shells or masks where the feet joined the body, although crests were sometimes engraved on either side
of the body or under the lip. Cast double-scroll handles were usual until c.1745 and flying-scroll handles (with only one end joined to the body) thereafter, sometimes with leaf decoration.
The sauceboat was a form particularly well exploited in the 1730s and 1740s by the best Rococo silversmiths, often of Huguenot descent – in England, Paul Crespin (1694-1770), Paul de Lamerie (1688-1751), and Nicholas Sprimont (1716-71) – who produced shell-shaped bodies with ornate cast handles
in the form of dolphins, caryatids, birds, griffins, and animals, and cast and applied shells and marine creatures. The bodies of Rococo sauceboats are also sometimes decorated with cast and applied scrolls
and cartouches. Some of the highest-quality sauceboats are gilded inside. Among the finest examples of this period are the set of naturalistic shell-shaped sauceboats with sculptural figural handles made by Sprimont in 1743-4 for Frederick, Prince of Wales.
The prevalence of sauceboats with shell-and-fish motifs indicates the popularity during this period of rich sauces made with fish. Some rare examples have
a body with a double thickness of silver, to be filled with hot water to keep the sauce warm at the table.
In the 1770s the central foot
again became fasionable and bowls were deeper, with a tall loop handle replacing the
scroll handle. However, sauceboats were generally superseded by sauce tureens in this period, although they returned after the 1820s. In the 19th
century, sauceboats were often made in 18th-century styles as part of a ceramic dinner service. Common features of 19th-century sauceboats include a heavy cast foot, applied shell decoration, leaf-capped scroll handles, and three feet. The shell shape was also revived
and was produced in Sheffield plate as well as silver; similarly, the early double-lipped sauceboat was popular in the 1820s and 1830s; examples of this date can be distinguished from the early 18th-century versions by their high, inward-curving handles. Sauce-boats of this period were commonly produced in large sets of varying sizes, especially in response to the expansion of the hotel and catering trades after the mid-19th century.
Entree dishes•
DESIGN the cover may have gadrooned rims on the inside to match the base when turned over and used as a dish.
• CONDITION the cover and handle should both fit properly; lead may show on Sheffield-plate examples –this is caused by bleeding from lead-filled plated and applied handles under heat.
• COLLECTING most entree dishes found today are not in good condition because they have been subjected to considerable use – only the best are collectable; lack of detachable handle (or handle soldered on) reduces value; plated heater bases are often found separately.

Decorative tableware
In the 18th and 19th centuries the utilitarian plate on dining-tales was complemented by richly
decorative pieces such as bread-, fruit- and cake-baskets, epergnes, and centrepieces. Made as much to display wealth as to be practical, these are characterized by high-quality casting, chasing, and, especially on baskets and epergnes, piercing. Such objects are among the most popular with collectors today because they are particularly attractive as
display pieces on a table.
SILVER EPERGNES
First used at the French court in the 1690s and in England c.1715, the epergne was an elaborate centrepiece for the dinner-table or sideboard. The name “epergne” is probably derived from the French word epargner, meaning “to save”: space could be saved on the table by
bringing together several dishes on one stand. By the 1740s the epergne was associated with the dessert course and generally took the form of a central
pierced basket surrounded by four to six pierced dishes or baskets for holding fruit or sweetmeats. It was most popular during the mid-18th century, when the light and delicate pierced forms, often ornamented with cast shells and flowers, were particularly suited to the Rococo style. Some epergnes, particularly those by the leading English maker Thomas Pitts (c.1723-93), demonstrate the contemporary vogue for chinoiserie, with their pagoda-like canopies with suspended bells.
In the 1760s and 1770s epergnes became wider and headier with the addition of more baskets, and in the 1-80s the influence of the Neo-classical style was
evident, with simpler oval or circular baskets, sometimes with blue glass liners, and decorated with Vitruvian scroll borders and swags. The leading specialist maker of epergnes in late 18th-century England was Thomas Pitts’s son William Pitts (active 1781-1806). Like other silversmiths, he offered clients a choice between more expensive epergnes, which had cast branches and decoration, and less expensive examples with mechanically produced ornament.
Heavier and more solid than 18th-century examples, Regency epergnes are usually mounted on a heavy Square or round foot, with branches ending in large floral sockets supporting cut-glass bowls rather than pierced silver baskets. Very few epergnes were made after this period, as they were generally replaced by the ornamental centrepiece.
SILVER CENTREPIECES
Large centrepieces as a decorative focal point for the dining-table or sideboard have always been among the most expensive items of plate and were often displayed as a sign of the wealth and status of the owner. One of the most famous and inventive pieces is the English silver-gilt Poseidon or Neptune centrepiece of 1741, made for Frederick, Prince of Wales. It features an elaborate stand of sculptural cast dolphins and mermen and is decorated with shells and marine creatures. Although this piece bears the maker’s mark of Paul Crespin (1694-1770), it may in fact have been designed and made by Nicholas Sprimont (1716-71 ); both were
leading English Huguenot makers of Rococo silver. The centrepiece was made with many matching salt-cellars and sauceboats, as befitting a grand table service for a royal patron.
Regency and Victorian centrepieces from the
19th century appear more frequently frequently at auctions today (although North American pieces are rare). Made with or without branches for candles, they usually have a central bowl, either solid silver or pierced with a glass liner, for fruit or sweetmeats. Centrepieces with all their original glass liners are rare today. Female caryatid figures supporting a bowl on a stand with heavy scroll or paw feet are characteristic of the Regency period, whereas later 19th-century centrepieces were made in
a huge variety of designs – naturalistic, sculptural figures were particularly popular. Many Victorian centrepieces were supplied with a flat, mirrored stand known as a “plateau” to enhance the decorative effect, but very often these became separated from the centrepiece and were sold on their own.
In the 19th century there was also a great demand for presentation plate, and the most important firms, such as Hunt & Roskell (est. 1844), Garrards (est. 1802), and Elkington & Co. (est. c.1830) in England, and Odiot in France, employed sculptors to design magnificent silver or electroplate centrepieces for historic or sporting occasions. Such pieces were shown at the 1851 Great Exhibition in London. Centrepieces were also made in Germany and Austria, notably by the firm of Klinkosch, but these are not always of such good quality as English and French pieces because the metal is often thinner. By the second half of the 19th century centrepieces had been scaled down in size and elaborateness, with a single basket on a stand becoming the usual form. This developed into the dessert stand, which had replaced the centrepiece by the end of the century.
Regency and early Victorian baskets were produced in a wide variety of styles, but in many cases they can be distinguished from 18th-century examples by an unpierced body that is embossed and chased with heavy scrolls, flowers, and foliage, or radiating lobes. Silversmiths in the 19th century also reproduced the shell-shaped designs and elaborate patterns that were typical of the Rococo period.
Victorian baskets are generally less expensive and more readily available to collectors today than examples from the 18th and 19th centuries. The handles on these baskets are sometimes bent or damaged (or have been removed altogether), as the weight of the unpierced body puts strain on them. Any basket that does not have a handle should be carefully examined to see if the handle has been removed. As on earlier examples, the feet may also have been pushed up into the body of the basket if it has at some stage been overloaded.
SILVER BASKETS
Silver baskets designed for holding bread, fruit, cake, or sweetmeats are known from the early 17th century, but most of those surviving today date from (.1730 onward. They are oval or circular with pierced sides,
a flat base on a raised foot or four cast feet, and a fixed or swinging bail handle. In many cases, the flat base was engraved with a coat of arms. In the late 1730s and 1740s the leading English silversmiths Paul de Lamerie (1688-1751), Paul Crespin (1694-1770), and
James Schruder (active 1737–(.1752) produced intricate Rococo baskets with delicate pierced designs of scrolls, circles, crescents, and quatrefoils, elaborate engraving and chasing, and asymmetrical handles with cast and applied masks, animals, figures, and birds.
Another feature typical of the Rococo fashion for novelty was the imitation of inexpensive materials in silver; on baskets dating from the first half of the 18th century the sides are often pierced and chased to give the impression of wickerwork strips. Some extremely rare and expensive baskets by the best makers were made in the form of sculptural scallop shells with scroll handles.
By the late 18th century silversmiths used hand-piercing only for the finest baskets, as the majority of pierced parts were mass-produced quickly and
accurately using the newly developed fly-punch. The silver sheet was also much thinner than on earlier pieces, so baskets of this date should always be carefully checked to make sure that the piercing is intact. Simple wirework baskets embellished with chased and applied motifs such as flowers, vine leaves, and sheaves of wheat (for bread-baskets) were also popular in the late 18th century.
