The celadon bowl has straight-lined sides. The surface is evenly coated with a dark bluish green glaze. The celadon bowl rests on a rather tall foot, which was hollowed out from the bottom. The designs are present only on the inside of the vessel with the peony motif.
Initially, Goryeo potters learned much of the technical expertise from the celadon traditions of Song-dynasty (960–1279) China, particularly of its southern coast. A Song envoy, Xu Jing (1091–1153), who visited the Goryeo capital, Gaeseong, in 1123, noted the resemblance of Goryeo ceramics to the celadons of China's Yue and Ru kilns. We see in early Goryeo examples a conscious emulation of certain stylistic features of Chinese wares—such as the shapes of bottles and bowls, and standard decorative motifs including lotuses, peonies, flying parrots, and scenes of waterfowl by the pond.
By the mid-twelfth century, Goryeo potters and patrons turned to articulating native tastes. This coincided with the consolidation of major celadon industries near the southwestern coast of the peninsula, in Jeolla Province—the Buan and Gangjin regions especially. The latter remains, today, the center of modern celadon production and of revivals of Goryeo traditions. The culmination of Goryeo celadon can be seen in inlaid (sanggam) celadon, a rarity in China. The delicate technique of sanggam involves etching the desired motifs on the dry clay body and filling in the carved space with black and/or white slip, after which the translucent glaze is applied and the vessel fired. The best of Goryeo inlaid celadon is breathtaking in its splendid presentation of clean form, vibrant design, and subtle yet alluring color combination of white, black, and green.
