【摘要】 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.更多还原

【Abstract】 Several shards of sacrificial red porcelain from Guan kiln of Jingdezhen during Xuande period were selected and study on the color mechanism was carried out using various non-destructive approaches. Microscopic observation shows that the different color areas have similar transparent glaze surfaces,and the color difference mainly depends on the red layer in glaze. Composition analysis results show that the contents of colorant copper for different color samples are almost the same. However,X-ray absorption fine structure( XANES) analysis reveals the differences in Cu chemical state among different hues of the samples. This indicates that the color mechanism of sacrificial red porcelain is closely related to the state of colorant copper.更多还原
