[A color analysis of the Han dynasty's Yangling Tombs colored pottery figurine by spectroscopy].

Many colored pottery figurines have been discovered from Yangling Tombs in which Han Jingdi, Qi LIU, the fourth emperor of Xi Han dynasty was buried together with his Wang empress. They were of important academic and aesthetic value. The analysis of the colored pottery figurines from Yangling Tombs of Han Dynasty was realized by X-ray diffraction, emission spectrum, infrared spectrum, X-ray fluorescence and fiber optics reflectance spectroscopy(FORS). Consequent results showed that the colored components were respectively mercuric(II) sulphide(HgS), ferric(III) oxide(Fe2O3), and Carbon(C), among which mercuric(II) sulphide was an artificial pigment.
