采用多种无损方法,分析若干明宣德景德镇官窑祭红瓷器残片.显微观察表明,不同呈色区域表层都有相似的透明釉,其呈色差异主要取决于红色颜料层.成分分析显示,不同呈色样品的釉中着色剂Cu的含量基本相同.然而,X射线吸收精细结构(XANES)分析指出,不同呈色样品中着色剂Cu的价态和近边结构有所不同.由此可见,祭红的呈色机制与着色剂Cu的赋存状态密切相关.
A number of non-destructive methods were used to analyze the porcelain fragments of the kiln red porcelain from Jingdezhen in Xuande Prefecture.The microscopic observation showed that the transparent glaze was similar in the surface of different color areas, the color difference mainly depends on the red pigment layer.Component analysis showed that, However, the analysis of X-ray absorption fine structure (XANES) indicates that the valence and the near-edge structure of the colorant Cu in different colored samples are different, which shows that the content of Cu in the glaze of different colored samples is basically the same. , The red color mechanism is closely related to the presence of colorant Cu.
