邢窑透影白瓷透光机制研究

As the earliest kiln produced white porcelain, the Xing Kiln played a decisive role in promoting the development of white porcelain technique. Among the products of Xing Kiln, there was one kind of white porcelain, which had special translucency, called Translucent White Porcelain. The Translucent White Porcelain attracted large numbers of researchers, since it embodied the highest technological level of Xing Kiln. In previous studies, the differences between Translucent White Porcelain and other white porcelains from Xing Kiln had been discussed. However, the absence of theoretical explanation of its light transmission mechanism had hampered the further research on the traditional crafts of Translucent White Porcelain. Therefore, it was necessary that carrying out an overall study on the light transmission mechanism of Translucent White Porcelain. In this proposal, the Translucent White Porcelain from Xing Kiln was chosen as the research object. The analysis of visible light spectrophotometer, OCT, SEM and SR-Micro-CT planned to be performed on these samples. Then, the light transmission mechanism of Translucent White Porcelain would be discussed based on the theory of light transmission in modern ceramics. It is expected that this research would shed light on the research of traditional crafts of Xing Kiln, and also provide some reasonable basis for the development history of Chinese porcelains.

邢窑作为最早烧制白瓷的重要窑址，在历史上曾对推动白瓷技术的发展起到过举足轻重的作用。在邢窑所生产的白瓷当中，有一类因具有特殊透光性而明显不同于其它品种，被学术界称为“透影白瓷”。透影白瓷的制作难度极大，体现了邢窑的最高工艺技术水平，吸引了大批学者的关注。在以往的研究中，对透影白瓷透光性的解释，仅仅止步于探究其与邢窑其它白瓷品种在成分等方面的差别，始终缺失了对其透光机制的理论阐释。这种情况非常不利于进一步探讨透影白瓷的制作工艺。因此，对透影白瓷开展更为深入全面的透光机制研究是十分必要的。本项目拟以邢窑透影白瓷作为研究对象，利用光学相干层析成像、扫描电子显微镜等现代分析技术对采集样品进行测试，再基于现代陶瓷材料透光理论模型，对其透光效果的形成机理进行科学地阐释，为今后探究透影白瓷制作技术和复原古代工艺奠定坚实的基础，同时还有助于理清北方白瓷的发展脉络和进一步完善我国陶瓷发展史。
