Study on mural painting pigments of Fuxi Temple,Tianshui,Gansu Province

为了解甘肃省天水伏羲庙壁画的制作工艺和颜料成分,采用偏光显微镜、显微拉曼光谱和扫描电子显微镜-能潜分析对6个样品进行了分析。结果表明,所使用的颜料为矿物质颜料,多为绿,白、红、蓝色等。其绿色颜料为人造碱式氯化铜,白色颜料碳酸钙,红色为朱砂和铅丹,蓝色颜料为青金石。

To obtain information on the mural painting layers and the pigments ever used in Fuxi Temple,Tian- shui,Gansu province,six samples were examined by polarized light microscopy（PLM）.cross - sectioning,Raman spectroscopy and scanning electron microscopy with an attached energy - dispersive spectrometer.The results show that pigments used are all derived from minerals.The most - used pigments are green,white,red,blue,etc.The green pigments are man - made copper trihydroxychlorides,the whites are calcite,the reds are cinnabar and red lead,and the blues are Lapis Lazuli.
