This large stoneware bowl has an olive-green glaze, and a fine network of cracks. A plain medallion decorates the centre. It has scalloped rim. In heavily potted bowls of this type, the celadon glaze, which is thick, translucent, and crazed, often forms a pool at the bottom.Celadon wares were probably introduced to Thailand from China during the early 14th century. By this time, Chinese celadons were being produced in large quantities commercially. The word 'celadon' is a 17th century French term for green-glazed wares. It comprises the green stoneware of Yue, Yaozhou and Longquan kilns in China. The green colour is attributed to the iron oxide in the glaze. Celadon wares were also produced at northern Vietnamese and Thai kilns and competed for export markets during the 15th century.The royal cities of Sukhothai and Si Satchanalai in north-central Thailand were at the heart of one of the largest ceramic-producing centres in Southeast Asia during the 14th century. Si Satchanalai, which was later renamed Sawankhalok, came to refer to ceramics that originated from either of these two areas.
