繁昌窑青白瓷胎体配方工艺一直停留在理论推理阶段, 尚未有确凿的测试数据和模拟实验加以证实。 为深入探究繁昌窑的胎料配方工艺, 选取了繁昌窑址附近的多种瓷土样品进行了测试分析, 并采用了古代制瓷工艺进行了模拟烧制。 主要运用了波长色散X射线荧光光谱法(WDXRF)、 红外光谱(FTIR)和X射线衍射(XRD)等光谱分析方法对瓷土成分进行测试; 借助同步热分析(TG-DSC)对样品烧造温度进行了探索; 通过模拟烧制陶瓷样品, 对繁昌窑青白瓷的烧制工艺进行了研究, 并对烧制的陶瓷样品进行显微结构分析。 研究表明, 繁昌窑附近的几种瓷土无论是单独制胎还是添加高岭土混合制胎, 其烧成温度皆接近古代繁昌窑青白瓷的烧制温度。 繁昌窑附近的瓷土是可以作为制作古代青白瓷的原料之一, 但由于其中的铝含量较低, 不能单独用来制作青白瓷胎体的原料, 繁昌窑青白瓷在制作过程中应添加了其他富铝类原料。 该研究对探索古代繁昌青白瓷的生产工艺及其蕴含的科学价值, 提升繁昌窑在中国陶瓷工艺技术发展史上的地位等具有重要的学术意义, 并可为现代陶瓷产业技术改进提供有益启示。

The formula process of bluish white porcelain body is still in the speculation stage. There exist no tangible proofs and simulated experiments to clarify the underlying craft. In order to explore the formula process, various china clays near the Fanchang Kiln have been characterized, and simulative firing experiments in the virtue of ancient porcelain technology have also been performed. Different characterizations including wavelength-dispersive X-ray fluorescence (WDXRF) XRD and FT-IR spectra was applied to determine the composition of the several china clays nearby the Fanchang Kiln. Meanwhile, the firing temperature was explored by TG-DSC analysis. Based on the above analysis, simulation firing was performed to study the possible firing process. And the microstructures of resultant samples were characterized by optical microscopy. Experiments evidences indicated that these china clays can be used as the raw material to fire bluish white porcelain body of the Fanchang Kiln. Considering aluminum content of these china clays is lower than that of the bluish white porcelain body, some materials containing high alumina component may be introduced in the production of the bluish white porcelain. This research has huge academic significance in understanding the production technology and promoting the status of the Fanchang Kiln in the development history of Chinese ceramic technology. This research also is helpful to improve the modern ceramic technology.
