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.
