Korea’s close proximity to China has resulted in a marked Chinese influence in its ceramic production, ev ident in both the forms and the techniques used by potters. However, Korea has also produced stonewares and porcelains unique to its culture.
THE SILLA AND KORYO PERIODS
During the Silla kingdom (57 BC—AD 935) ceramic production in Korea consisted of grey- or brownish-bodied stonewares of distinctive architectonic form. Tall vessels with hemispherical bowls on an elongated spreading foot were decorated with geometric
windows and incised bands. Bowls were decorated with punched circlets, small repeated motifs, scratched geometric patterns, and, occasionally, animals or humans. Drawing inspiration from the Yue wares of south-eastern China, Korean potters developed celadon wares during the Koryo period (918-1392). Even if some of the forms are noticeably Chinese, there is almost always a distinctive Korean feel to them.
The green glaze is of a subtle tonality akin to the colour of the famous Ru wares of the northern Song Dynasty. However, er, the sangam celadons, which are painstakingly inlaid with black-and-white clays, are unique to Korea. A wide range of objects was made, including large blossom vases, ritual water ewers, and tiny covered boxes. Porcelain was also produced, albeit in very limited quantities, during the Koryo period.
CHOSON DYNASTY (1392-1910)
Developed from the sangam celadons of the Koryo period are the robust and often crude punch’ong wares, a greyish-green celadon-type stoneware made for about the first 200 years of the dynasty. Production ceased at the time of the invasion of Korea by the Japanese leader Toyotomi Hideyoshi (1592-8). The wares are decorated by stamping and washing through with slip. Decoration may feature tiny repeated motifs, flower-heads, or scrolls. Korean wares are generally very heavily potted with a curiously sticky glaze. The greyish-green glaze is thin, translucent, and mostly crackled, and it occasionally flakes. Choson whitewares were made throughout the period; earlier wares were often plain white, although many pieces can be painted in underglaze copper red, iron brown, or blue. Bulbous forms, often with faceted sides, are characteristic of the later Choson period, as are pierced vessels such as brushpots, pipe rests, and waterpots.
Early stoneware
• BODY dull dark grey or brown; potting tends to be very thick, and there is strong tendency for the items to warp
• FORMS “architectural”
• TYPES funerary wares
• DECORATION pierced and incised; often geometric patterns, rarely figures
celadon
• BODY generally a distinctive greyish blue-green like the classic Ru ware of the northern Song Dynasty
• GLAZE of greyish-olive tone; usually irregular; frequently crackled
• IDENTIFICATION celadon wares were fired on gritty kiln supports, often leaving crude patches on the underside of the foot-rim
• DECORATION the miniaturized inlay technique (sangam), using black-and-white clay, is unique to Korea
Porcelain
• BODY heavily potted; sometimes large pieces are warped or cracked; pierced and carved wares of the 18th and 19th centuries are very sophisticated
• GLAZE bluish or greenish irregularly crackled glaze
• DECORATION most common is the dragon; also cranes, tigers, and other animals
Marks
Most ceramics are unmarked before the late 19th century

Qing after 1800
During the Qianlong reign period (1736-95) the directorship of the imperial kilns passed from imperial officials to regional supervisors, and from that time there followed a slow decline in the quality of wares from Jingdezhen in Jiangxi Province. While some fine pieces continued to be made, there was a general tendency to over-elaborate in both form and decoration.
BODY AND GLAZE
The changes in the quality of the material were gradual and, when wares are unmarked, it can be very difficult to distinguish between one reign period and another. The dragon and phoenix wucai bowls, which were first made during the Kangxi reign period (1622-1722), continued to be made right into the 19th century and are a good example of the problem; their smooth bluish-white glaze and neatly drawn enamelling are virtually the same whether they are from the Qianlong or the Jigging reign periods (1736-1820). Without reference to the seal marks, most specialists would be hard put to tell the difference.
There was, however, a perceptible decline in quality during the Daoguang reign period (1821-50), and the inferior quality persisted to the end of the dynasty. The cool and lustrous glaze gave way to a grainy off-white, while the enamels were duller or harsher than their
brilliant predecessors. The decoration of enamelled porcelains was arranged in a crowded or ineffective manner, with over-complicated colour combinations.
STYLES, SHAPES, AND DECORATIVE THEMES The porcelains that had been produced in the 18th century continued to be made in the 19th. They included Ming-style blue-and-white wares such as moon flasks and pear-shaped bottles, as well as large saucer dishes. Likewise, monochromes continued to be produced, notably sang-de-boeuf red, “peachbloom”, and yellow. There were also artistic innovations, among them the production of “medallion” bowls.
• GLAZE marked deterioration in quality from the Daoguang period; “European-green” turquoise wash appears on the inside of many vessels
• DECORATION tendency to over-elaborate, complicated colour schemes and overcrowding; greater use of gilding; introduction of “medallion” bowls and “rice-grain” pierced wares; use of show and other auspicious characters; heavy use of enamels
Reign marks
Reign marks were inscribed on most 19th-and 20th-century domestic, imperial, and export porcelain; the mark shown here is in conventional script for the Guangxu reign period (1875-1908)
