Joseon Dynasty porcelain

Joseon white porcelain and Buncheong

During the Joseon Dynasty, (1392–1910) ceramic ware was considered to represent the highest quality of achievement from imperial, city, and provincial kilns, the last of which were export-driven wares. This was the golden age of Korean pottery, with a long period of growth in imperial and provincial kilns, and much work of the highest quality still preserved.

Wares evolved along Chinese lines in terms of colour, shape, and technique. Celadon, white porcelain, and storage pottery were similar, but with slight variations in glazes, incision designs, florality, and weight. The Ming influence in blue and white wares using cobalt-blue glazes existed, but without the pthalo blue range, and the three-dimensional glassine colour depth of Ming Dynasty Chinese works.

Simplified designs emerged early on. Buddhist designs still prevailed in celadon wares: lotus flowers, and willow trees. The form most often seen was that of pear-shaped bottles. Notable were thinner glazes, and colourless glazes for buncheong or stoneware.
After the prolonged fall of the Ming dynasty, immigration of some Chinese master potters occurred in southern coastal Korea. Qing colouring, brighter and almost Scythian in enamel imitation, was rejected by Korean potters, in favour of simpler, less decorated wares in keeping with a new dynasty that built itself on military tradition.

Generally, the ceramics of this dynasty is divided into early, middle, and late periods, changing every two centuries, approximately; thus 1300 to 1500 is the early period, 1500 to 1700 the middle, and 1700 to 1900–1910 the late period.

The wares began to assume more traditional Korean glazes and more specific designs to meet regional needs. This is to be expected, as the Scythian art influences were of the former dynasty. The rise of white porcelain occurred as a result of Confucian influence and ideals, resulting in purer, less pretentious forms lacking artifice and complexity.

In 1592 during the Japanese invasion of Korea, entire villages of Korean potters were forcibly relocated to Japan permanently damaging the pottery industry as craftsmen had to relearn techniques because the masters were gone.

Goryeo Dynasty porcelain

By Ceramic Design



The Goryeo Dynasty (918–1392) achieved the unification of the Later Three Kingdoms under King Taejo. The works of this period are considered by some to be the finest small-scale works of ceramics in Korean history.

Key-fret, foliate designs, geometric or scrolling flowerhead bands, elliptical panels, stylized fish and insects, and the use of incised designs began at this time. Glazes were usually various shades of celadon, with browned glazes to almost black glazes being used for stoneware and storage. Celadon glazes could be rendered almost transparent to show black and white inlays.

While the forms generally seen are broad-shouldered bottles, larger low bowls or shallow smaller bowls, highly decorated celadon cosmetic boxes, and small slip-inlaid cups, the Buddhist potteries also produced melon-shaped vases, chrysanthemum cups often of spectacularly architectural design on stands with lotus motifs and lotus flower heads. In-curving rimmed alms bowls have also been discovered similar to Korean metalware. Wine cups often had a tall foot which rested on dish-shaped stands.

Korean pottery and porcelain

By Ceramic Design



The Three Kingdoms of Korea (57 BC-668 AD), namely Silla, Goguryeo, and Baekje, provided the beginning of Korean ceramic history. Rough domestic wares for the people were produced from numerous kilns. Likewise a number of very sophisticated statues of royal figures, guardians, and horses, equivalent to Chinese Han Dynasty figures, used for domestic and imperial votive shrines, as well as for escorts of the dead in tombs of the nobles and kings, were turned on potter’s wheels, while others were formed using the traditional hammered clay and coil method.

During the Unified Silla period (668–935) pottery was simple in colour, shape, and design. Celadon was subsequently the main production, with baekja porcelain wares developing slowly in the 14th century, when the pace accelerated with new glazes, better clays, and surprising variations of the white of different clays.

The kilns at the time had to compete with Chinese wares on a variety of social levels. The Korean ceramic masters decided to distinguish Korean baekja or white porcelain from Chinese imports by maintaining simplicity in design when the practical problems of finding pure white glazes were solved. Dating of glazes from this era has revealed a celadon or jade patina beneath white glazes.

Baekja wares came from highly refined white clay, glazed with feldspar, and fired in large carefully regulated and very clean kilns. Despite the refining process, glazes in white colours always vary as a result of the properties of the clay itself; firing methods were not uniform, temperatures varied and glazes on pieces vary from pure white, in an almost snowy thickness, through milky white that shows the clay beneath deliberately in washed glaze, to light blue and light yellow patinas.

The baekja wares reached their zenith immediately before the Joseon Dynasty came to power. Fine pieces have recently been found in the area about Wolchil Peak in the Diamond Mountains. The transitional wares of white became expressions of the Joseon Dynasty celebrations of victory in many pieces decorated with Korean calligraphy. Traditionally white wares were used by both the scholarly Confucian class, the nobility, and royalty on more formal occasions.

Simultaneously, the Buddhist traditions demanded celadon-glazed wares, and cheongja pieces of celadon porcelain with more organic shapes drawing on gourds, with animal and bird motifs that evolved very quickly. In some ways these were over-decorated wares, using exaggerated forms, stylized repeating designs, and a wide variety of organic patterns.

Cheongja wares used refined earth clays with a bit of iron powder added, then a glaze with a bit of added iron powder added once again, then fired. The glaze dried to a hard finish and was durable with a slightly shinier and glossier finish, in an oily way, than whitewares.
