This celadon bowl, made in the years when Goryeo reached the zenith in celadon art, has height of 6.05 centimeters, mouth dimension of 16.8 centimeters, and foot dimension of 4.4 centimeters. The bowl was excavated at the grave of Mun Gong-yu -- an eminent Goryeo official who died in 1159 -- in Gaepung-gun, Gyeonggi-do along with his memorial marker buried at the grave. It is the oldest existing Goryeo celadon ware decorated by the unique inlaying technique developed by Goryeo potters. The bowl is characterized by narrow foot, gently rounded sides, and widely everted large mouth. At the center of the inner bottom is a large circular flower motif rendered with the “reverse-inlaying” technique by which the central motif is highlighted by its background inlaid in white slip. The entire inner surface except the center and the edge is lavishly decorated with scroll motifs, also rendered by the same technique. Meanwhile, the outer surface features a band of foliage just below the mouth rim as well as chrysanthemum sprays on five points of the middle body, including flowers inlaid with white slip and stems and leaves with black. In addition to the contrast and balance between the decorative motifs and colors and inlaying techniques, the bowl is widely praised for the attractively translucent celadon glaze evenly coating the surface. It is also considered an important source of knowledge, containing ample information on the development of the inlaying technique by Goryeo potters during the mid-12th century.
