新疆库木吐喇石窟壁画颜料的分析研究

Analysis of the Pigments in the Kumutula Grotto Murals,Xinjiang,China

为了解新疆库木吐喇石窟壁画颜料成分,利用激光拉曼光谱、光学显微镜、扫描电子显微镜分析等方法,对石窟壁画颜料进行了分析研究。结果表明:颜料主要有红色铁红、铅丹,蓝色颜料青金石,绿色颜料氯铜矿,金色的金箔,白色颜料石膏,黑色颜料炭黑和二氧化铅。

In order to identify the components of pigments used in the murals of the Kumtula Grottoes,Raman spectroscopy, light microscopy, and electron scanning microscopy have been used to analyze the chemicals contained in paint samples obtained from the site. The results showthat red pigments are mainly haematite and miniumite（red lead）, the blue is lapis lazuli, the green is atacamite, the gold is gold foil, the white is gypsum, and the black are charcoal and lead dioxide.
