Abstract
Anorthite crystallization between the body and glaze of ancient ceramics has regional characteristics. According to the microstructural characteristics of the body and glaze, ancient Chinese ceramics can be mainly divided into four types: Yue kiln type, Longquan kiln type, Ding kiln type and Changsha kiln type. Anorthite crystallization is closely related to the elemental composition of the body and glaze. The microstructure of Minhou kiln ceramic chips shows that when the Al2O3 content of the body is high, fine feldspar crystals precipitated into the layer of molten glaze in contact with the body surface during firing. This unique microstructure can help identify some ceramics.
