Explanation

Chinese traditional high-temperature glaze developed on the basis of lime glaze. This glaze uses feldspar instead of part of limestone to increase the K2O and Na2O content in glaze and correspondingly reduce the CaO content. The composition of glaze will evolve into lime alkali glaze. It is characterized by high temperature viscosity, difficulty in flowing, thick glaze layer, soft glaze luster, no dazzling feeling, and reduced the tendency of smoke and cracking of glaze. It is mainly used to prepare products with deep glaze color or body color, Such as plum green, bean green glaze, etc. For example, the Longquan celadon glaze in the Southern Song Dynasty, Yuan Dynasty and Ming Dynasty in China, various high-temperature colored glaze produced in various kilns after the Southern Song Dynasty, and Jingdezhen white porcelain glaze since the Yuan and Ming Dynasties all belong to this category
