Yue ware was succeeded by Northern Celadon and then in the south Longquan celadon. In the Tang Dynasty, porcelain was divided into celadon and white porcelain. Most Longquan celadon, a very important ware in medieval China, was stoneware. In the Goryeo period, jade green celadon ware became more popular. The more modern levels contain Chinese celadon and porcelain, and Arabic glazed pottery. Numerous shards of porcelain were recovered, indicating the predominance of white porcelain and celadon. White porcelain became popular in the 15th century, and soon overtook celadon ware. They were frequent adornments on celadon vases. Some other types of pottery, especially Longquan celadon and Cizhou ware, continued to flourish. The development of celadon pottery flourished in the 12th and 13th centuries. Chambered kilns were usual for making Longquan celadon. Pieces made with a celadon glaze are themselves often referred to as "celadons". The dynasty, however, is most prominently renowned for its use of celadon ware. Inland kilns replace them, putting an end to the age of celadon.
