WINE-GLASS WITH LAMP-WORKED DECORATION, TULIP-SHAPED JUG, SHALLOW BOWL
THE JUDGMENT OF PARIS
Nevers, Prance, 1777. Hi. 210 mm (8-25 in.)
Verre de Nevers: This technique origin-
ated in Nevers in the late 16th century, and
it is more closely allied to lamp-working
than to the normal techniques used for
creating glass objects, such as blowing and
moulding. It flourished in Europe for
some two centuries. This delightful group,
depicting the judgment of Paris, was made
in Nevers in the heyday of the glass
figurine, between the late 17th and early
18th centuries. The figures were made by
softening rods of glass of different colours
and winding them over a metal armature.
Every fold of the garments on this group
has a metal base below the glass. When the
glass was sufficiently thick, and after
repeated reheating, it was modelled to
shape with the aid of prods and pinchers. I n
Verre de Nevers groups, decorative details
such as leaves are made entirely of glass,
with no supporting core, while such forms
as birds might be blown.
WINE-GLASS WITH LAMP-WORKED DECORATION
Saxony? early 18th century. 111. 140 mm (55 in.)
Lamp-working is a technique used by
glass-makers to make objects by using only
a single flame as a source of heat. Glass
rods are normally used, held over the
flame and melted or softened to the
desired shape. In modern times, the most
popular lamp-worked objects are small
animals made out of coloured glass rods
melted down, bent and joined to the
required form. Details like eyes are made
by putting a small drop of molten glass on
the object, with possibly another centred
on the first drop to form the pupil. The
ornate stem-work on Venetian and /aeon
de Venise wine-glasses is closely allied to
this technique. One of the rare instances of
true lamp-working on a blown glass is the
wine-glass illustrated, which is one of a
series that have a band of lamp-worked
decoration round the centre of the bowl.
The work stands out in three dimensions
from the bowl, the small Cupid being
almost free-standing; he holds a garnet in
his hand. The provenance of these vessels
is not certain.
TULIP-SHAPED JUG
Karl Kopping, Berlin, c. 1900
I It. .120 mm (126 in.)
Karl Kopping (1848-1914) was a painter
and etcher in Berlin. Between 1892 and
1900 he designed some tall decanters and
goblets made at the lamp from tube glass.
At that time Germany had lor some ten
years been under the influence of the style
for naturalism created by Emile Galle of
France. It became known in Germany as
the Jugendsttl, and Karl Kopping’s exag-
gerated Art Nouveau glass vessels form a
part of this movement. The starting point
for his designs was the flower on its stalk,
and the colours he used could be both bold
and delicate. The stem of the glass
illustrated is in blue, the leaves are in
copper-green glass and the tulip-shaped
bowl has a metallic finish. The piece is
signed on the foot: ‘C. Kopping’. 1 lis work
became popular, and several museums
bought examples of it, but today they are
regarded more as period pieces.

It has always been the custom for glass-
blowers to amuse themselves in spare
moments by creating fantasies in glass.
These are known in the trade as ‘friggcrs’
—a word which possibly derives from the
Old English ‘Jrician’, to dance. In Scotland
they are called ‘whigmelccrics’. In the
19th and early 20th centuries friggcrs
included elaborate fountains surrounded
by birds with tails of glass fibres and fully
rigged sailing ships on spun glass seas, as
well as the objects mentioned on page 100.
The more elaborate friggcrs are usually
protected by a large glass dome. Friggers
were made for amusement, for family
presents, as an extra source of money, or
even for fully mercantile reasons. Travel-
ling glass-makers who visited fairs and
private houses produced many of these
novelties, having as their kit a bundle of
multi-coloured glass canes and a little
furnace heated by a tallow flame.
The ‘taking away’ or abrasive techniques of
glass-making have as long a history as glass
itself Even earlier, hieroglyphic inscriptions
had been engraved on hard stone vessels, and
we definitely know that as early as the 16th
century B.C. glass was being engraved in
Egypt. Most of this engraving was probably
done with pointed instruments or possibly
with a rotary wheel. Wheel-culling and
wheel-engraving are the two terms most
commonly encountered, and though they are
thought of as almost separate methods,
basically the techniques are the same. In
both, a rotating abrasive wheel cuts into the
glass surface. The mam distinction is that
large wheels are used for cutting, where the
worker holds the glass on lop oj the wheel,
between himself and his tool; and small ones
for engraving, where he holds it below the
wheel, so that he can see what he is doing.
Culling is characterised by large-scale,
geometric designs, usually relatively deeply
incised, and engraving by jine, detailed,
usually pictorial work.
Grinding and Cutting from a Raw Block of
Glass: This was the only ‘taking away’
technique that was used to produce a com-
plete vessel or other object. The method,
which was covered in the first chapter,
dealing with techniques before blowing
was invented, continued in use for a short
time after the 1st century B.C. The ring
illustrated is a good example of the method
used to produce a single decorative object.
One might imagine that a gem or even a
glass cameo was once set in the concavity
left by the glass-cutter at the front of the
ring. (lasting glass in moulds and blowing
glass were so much easier, that this tech-
nique, using rotary abrasion to shape an
object, fell into disfavour. It was con-
tinued primarily as a means of finishing off
already made glass forms, or as a means of
embellishment.

Early Wheel Engraving: The goblet illus-
trated, made of turquoise-blue opaque
glass with a gold ring at the rim and base,
is a famous example of early incised work.
Some glass vessels from the 18th Dynasty
in Egypt are decorated with incised
inscriptions such as that found by Sir
flinders Petrie at Tell el Amarna. A frag-
ment of a bowl at The Corning Museum of
C1 hiss bears a fragmentary inscription
relating to the wife of Amcnhotep III
(1412 1375 B.C.), and is said to reveal ‘the
characteristic tapering ends of wheel cuts’.
Whether the engraving on these early
vessels was done with a point or by means
of a rotating instrument has been tho-
roughly discussed by R. J. Charleston (see
Bibliography). For the most part it seems
that just a pointed instrument was used,
and it was only in the later Egyptian
period that there is evidence of wheel-
engraving on the glass, probably by the use
of a bow-lathe.
SHALLOW BOWL WITH PETAL DESIGN
Roman Empire, 7ih 5th century B.C.
Hi. 39 mm (155 in), diam. 174 mm (685 in.)
In the general Mesopotamia-Assyria-Asia-
Minor region, rotary abrasion was used to
sharpen up decorative motifs, which were
first produced by moulding processes.
There is a large family of bowls with
radiating petal motifs—one being illus-
trated here—the earliest of which is known
to date from not later than 700 B.C. These
were produced by being cast into moulds,
and finished by grinding and cutting. As
abrasive powder on the wheels, emery was
probably used; this was apparently known
in Egypt at least as early as the 18th
Dynasty. The known use by the Egyptians
of tubular metal drills in cutting granite
was probably paralleled further East in the
first millenium B.C. Some such means
must have been employed in the hollowing
out of vessels like the famous ‘Sargon vase’
(see first chapter).
It is not known what type of abrading
equipment was used in Roman times to
decorate glass. It has been suggested that
an all-purpose tool could have been used,
which could be adapted as lathe, drill or
engraving wheel as needed. The Romans
definitely used abrasives such as emery for
cutting, and pumice stone for polishing the
cuts. Probably from Egypt came a group
of facet-cut and ‘diamond’-point engraved
bowls from the ist and 2nd century A.D.
(See Diamond-Point Engraving.) These
are the parent group from which are
descended all late Roman cut and engraved
glasses with figured scenes. The quality of
Alexandrian engraved work deteriorated
during the 3rd and 4th centuries A.D.
However, in the west, from some time in
the 3rd century A.D. onwards, a great
quantity of figured cut or engraved glass
began to be produced in Italy and the
neighbouring provinces, of which the dish
illustrated above is an example.
Figured decoration in engraved work was
not altogether abandoned by workers in
the eastern workshops, as is seen in some
later exports to the west from the east.
However, in general they began to con-
centrate on easier designs, suited to less
skilful engravers, and presumably for more
speedy production. The jug illustrated,
with geometric decoration in friezes, is an
example of the rather rough designs the
West Syrian/Egyptian workshops fav-
oured. It is in dark yellowish-green glass,
which is of rather poor quality, being
bubbly and streaky with impurities. The
fine linear and facet cutting of the earlier
period is not in evidence. Wheel-engraving
was now used to imitate facet cutting, with
designs of curved lines, circles and ovals.
The style took particular root in Egypt,
and probably in Syria also. Many of the
vessels of this type found in the west must
have been imports from these areas.
Diatreta are the most extraordinary and
most outstanding examples of the tech-
nique of abrasion ever made. From experi-
ments carried out by Fritz W. Schafer in
Germany and Barbini and Fuga in Italy it
has been proved with almost complete
certainty that these delicate cage cups were
produced by lapidary means, and not by
any other technique (see Bibliography). A
small battery of wheels and readily avail-
able abrasives, plus the skill of the en-
graver, are all that is needed to make a
diairelum from a solid, carefully annealed
blank. Diatreta are the finest product of
the Cologne and Trier glass-makers in the
4th century A.D. They have been found
in the Rhineland, on the Danube, in
Northern Italy and in Greece. The three
most beautiful, all with inscriptions, came
to light in Cologne. The inscription on the
one illustrated is in Greek, and conveys an
exhortation to drink.
With the decline of the Roman Empire in
the West, glass engraving died out. This
was largely because there was no (ine-
quality glass made after this time that was
suitable for engraving. In the East the
technique never ceased, and glasses with
cut decoration can be traced in unbroken
continuity through Sassanian to Islamic
times. Baghdad and Basra were noted for
cut glass in the 9th century A.D. and later.
In the 9th and ioth cerfturies, after a
renaissance under the dynasty of the
Samanids, a school of relief-cutting flour-
ished in Persia and probably in Meso-
potamia, which in Europe was not rivalled
until the end of the 17th century. The flask
illustrated is an early example of a shape
that was to remain popular throughout the
Islamic period. The scrolling engraved
design was to exert a great influence on the
mind of the Islamic artist.
Hedwigsglas in light brown clear glass, the
gilt-copper foot a later addition
So-called Hedwigsgldser represent the last
wheel-cut glass vessels to be produced in
the Orient, and are recognised as master-
pieces of Egyptian skill. Their origin is by
no means absolutely certain. These thick-
walled glasses carved in hochschnitl (deep
cutting) are maintained by B. Shelkov-
nikov to be the work of a 12th-century
White Russian workshop in Novogrudok,
which was presumably under the influence
of Byzantium. They are certainly a con-
tinuation of the art of rock-crystal cutting,
and more probably originated in Egypt.
The motifs used include stylised lions
and griffins between palm branches, as in
the illustrated example. Two of these
glasses reputedly belonged at one time to
St. Hedwig (1174-1243), wife of the Duke
of Silesia, and it is from her that the glasses
take their name. (Legend has it that the
saint caused water to change into wine in
one of these glasses.) Her niece, St.
Elizabeth (1207-31) also had a Hedwigs-
glas, reputed to give strength to women in
labour, which eventually came into Martin
Luther’s possession.

Facet-Culting is a form of decoration that
goes back certainly to the early Roman
period. Large, broad wheels were needed
to make the facets in the glass. R. J.
Charleston points out that Pliny mentions
some of the abrasives used for grinding in
Roman times, such as ’sand of Naxos’ for
emery, ’sands’ from India, Egypt and
Nubia, and certain stones from Armenia
and Cyprus. He also points out that
Theophrastus mentions pumice and also
emery in his History of Stones. Pliny
mentions Thebaic stone from Egypt and
pumice for the final polishing of marbles.
A wheel with a broad cutting or grinding
edge was certainly used to produce the
facet-cutting on this cup, which is in clear
glass with a greenish tint. Cups like this
found in England and Cyprus are thought
to originate from Western Syria or Egypt
and, in the later 2nd century A.D., from
East Syria.
During the 2nd century A.D. the East
Syrian glass-makers and decorators devel-
oped their knowledge of the art of glass-
engraving including facet-cutting. The
art lived on through Sassanian to Islamic
times. The flask illustrated, in clear glass
with a slight blue tinge, is a typical example
of the continued tradition of wheel-cut
decoration. Oval concave facets cover the
body of the flask, and the neck also has a
ring of facets. Previous to this, in Sassanian
times, wheel-cutting, particularly facet-
cutting, resulted in some striking glass-
ware. Most of the surviving examples from
this period arc cither facet- or linear-cut,
including characteristic shapes such as the
hemispherical bowls with concave cut
facets which were exported to the West
and East, even as far as Japan.
Facet-cutting, particularly for stem-work,
became popular in the second half of the
18th century. Facetted tumblers and
bottles were current in Bohemia, and in
Germany facet-cut knops appear on wine-
glasses from the Laucnstein and other
Hessian glass-houses in the first half of the
18th century. In England at the same time
glass-grinders were facetting the edges of
mirrors, and simple diamond-facetting
was beginning to appear on some glasses.
Scent bottles of opaque white glass and
blue glass, and snuff bottles dating from
about 1770, had all-over facetting and
were often enamelled and gilt. Once
thought to have originated from Bristol,
they more probably came from the Birm-
ingham, South Staffordshire or even Lon-
don area. From the middle of the 18th
century, facet-cutting became an estab-
lished form of decoration in England,
appearing particularly on wine-glass stems,
between c. 1760 to f.1810. Examples can be
found through to the modern period.
VASE WITH FACET CUTTING
By Keith Murray. Stevens & Williams, England,
1939. Ht. 206 mm (8-13 in.)
The architect Keith Murray (b.1893) first
began to take an interest in glass after the
Exhibition in Paris in 1925. He asked
himself why he found the conventional cut
crystal of England so unsatisfactory. After
analysing old English glass, he decided the
glass was better if left plain, or when it was
cut, if the cutting was in a ‘well organised
decoration’, flat cutting being particularly
appealing. The idea of an artist designing
for industry was beginning to be accepted
in England, and in 1932 it was arranged
that Murray should act as designer for
glass for Stevens & Williams at Brierley
Hill, near Stourbridge. During the seven
years he worked in glass he produced
designs for simple unornamented table
services and for some larger pieces. His
most important works are the large vases
and dishes in heavy metal decorated with
facet-cutting reminiscent of early Georgi-
an work. They powerfully express his
architectural feeling, and the decoration
matches the material superbly.
BOWL WITH FACETTING
By Miluse Roubiekova, Borske sklo, Czechoslovakia,
1958. Diam. 450 mm (17-7 in.)
After the political revolution in Czecho-
slovakia in 1948 the glass industry was
nationalised. The Creative Glass Centre in
Prague was set up in 1952, in order to
establish contact between the glass-works
and the artists and designers, and to
encourage research into new methods of
decorating glass. Czechoslovakian glass
has long been known for its great tradition
in lead crystal cutting, and like its British
counterpart, Bohemian crystal still enjoys
a large public all over the world. The
tradition continues, but finds new expres-
sion in less rigid cut-glass patterns, softer
patterns of a gently formalised character
being increasingly favoured. A good exam-
ple of the new trend is the free irregular
facet-cutting on this bowl designed by
Miluse Roubiekova made at the Borske
sklo, Novy Bor. The usual diamond or
star motifs are no longer in evidence, but
the unsymmetrical lines of the bowl still
enhance the brilliance of the glass.
Later Wheel Engraving: In gem-cutting,
wheels of various materials were certainly
being used by the 15th century to engrave
and polish. By the 16th century, the prin-
ciple of continuous rotary movement had
been established. Engraving equipment
driven by a foot treadle was in use by glass
engravers in the early 17th century. Caspar
I.ehmann, the greatest name in the revival
of glass-engraving in Europe in the late 16th
century, was an engraver of hard-stones
before he was a glass-engraver, and one-
can assume his equipment was more or less
the same for both crafts. Lehmann was
‘Imperial gem-engraver’ to the Emperor
Rudolph II at Prague in 1601, and in 1608
was described as ‘Imperial gem-engraver
and glass-engraver’. From the very begin-
ning, then, the glass-cutter undoubtedly
borrowed his ideas from the gem-cutter,
whose art was so closely allied to his own.
This was a tradition that was to continue
into relatively modern times.
Caspar Lehmann’s engraving is shallow—
because of the thinness of the glass—two-
dimensional and unpolished. Prague was
one of the centres for rock crystal cutting,
and this is reflected in the style of the
engraving, which is flatly cut and gains its
effect from the contrast between the white
engraved lines and the’dark background of
the clear glass. In 1600 I.ehmann obtained
an Imperial Privilege conferring on him
alone the right to practise the art of glass-
engraving in the Imperial domains I le
bequeathed his privilege to his pupil
Gcorg Schwanhardt the Elder, born in
Nuremberg, who worked with him at
Prague. In 1622 Schwanhardt returned to
Nuremberg, where he founded a brilliant
school of wheel-engraving which flourished
to the 18th century. The new potash-lime
glass developed in Bohemia and Germany
in the early 17th century was eminently
suitable for the technique of wheel-
engraving.

Hi. 394 mm (15-5 in.)
Schwanhardt’s work in rock crystal and in
glass shows a complete mastery of the
technique of wheel-engraving. His work
was both polished and unpolished, and he
often used as motifs landscapes with
figures, with formal baroque scroll work.
He sometimes added delicate diamond-
point work to his glasses. Among his
pupils were members of his own family,
his sons, Georg the younger and Hcinrich,
and three of his daughters. Other notable
artists among the Nuremberg engravers
were Hermann Schwinger (1640-83) and
Georg Friedrich Killinger (first recorded
1694, died 1726). They all engraved the
same characteristic type of tall goblet,
with hollow knopped stem. The family
of Johann Hess at Frankfort-on-Main
engraved similar glasses in the second half
of the 17th century. Johann Heel (1637-
1709) glass-engraver, silversmith, faience-
painter and engraver of prints in Nurem-
berg also engraved glass in a somewhat
different style, following the motifs he
used in faience painting.
COVERED GOBLET WITH HOCHSCHNITT CUTTING
By Friedrich Winter, Silesia, end of 171I1 century
Ht. 280 mm (11 in.)
{See also colour photograph iH)
During its most flourishing period (c. 1685-
1775) German glass-engraving was done
mainly by unknown artisans working for
themselves in north-eastern Bohemia and
Silesia. However, the best-known work
was done by the engravers to three German
courts. Friedrich Winter set up the first of
these workshops in 1687, with permission
from Count Christoph Leopold von Schaff-
gotsch, at Petersdorf in the Hirschbcrger
Tal. He used water power, and produced
many glasses in the Hochschnitt technique.
Under the patronage of Friedrich Wilhelm,
Elector of Brandenburg, Friedrich Win-
ter’s brother Martin (died 1702) set up an
engraving workshop in Potsdam near
Berlin in 1687. This was also run by a
water-power mill specifically to produce
works in Hochschnitt (deep cutting) and
Tiefschnitt (intaglio work). Martin Win-
ter’s highly gifted nephew Gottfried Spiller
worked here, becoming a partner in 1683.
His engraving included flowers, allegories,
portraits, coats of arms, sometimes in
Hochschnitt, and occasionally he used the
ruby glass of the Potsdam glass-house.
