This saucer bowl is decorated with floral motif at the centre with notched lines at the rim.The Phan kilns, which lie in Chiang Rai province, are similar to those in Sukhothai and Sawankhalok. However, they produced only celadons. These celadons were of an exceptional standard, with those of average quality considered far better than most of the celadons produced at Sawankhalok.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.
