Goryeo celadon

The ceramics of Goryeo 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.
