Microstructural study of white and black wares of Pacun and Xin’an kilns (Henan Province, China)
摘要
White and black wares hold a significant historical position in Chinese art and ceramics due to their distinctive decorative techniques. This study comparatively analyzed representative white and black wares from Pacun (Yuzhou City) and Xin’an kilns (Luoyang City) in Henan Province. The chemical composition of the bodies and glazes present no obvious difference, except for slightly higher TiO₂ and Fe2O3 contents in the Xin’an glazes than those in Pacun glazes. All bodies conform to the characteristics of high aluminum and low silicon of clay in the Chinese northern region. The color generation of the black decoration of both types of wares could be attributed to a joint action of Mn ions and hematite crystals, in which the Fe ions may be substituted by other ions. Besides, similar firing temperatures were used for the wares from Pacun and Xin’an kilns, which range from 1200 to 1250 °C.
