摘　　要：敦煌壁画经历了上千年岁月的洗礼后,变色情况严重,而铅丹变色就是敦煌莫高窟壁画颜料层最严重的一种变色病害。从光化学反应与微生物等角度,对铅丹颜料的变色原因及其在混合颜料中的稳定性进行了梳理与分析。结果表明:铅丹颜料变色病害主要受到紫外线以及微生物的影响,铅丹与朱砂或铁红的混合颜料较铅丹颜料更加稳定。Dunhuang murals have been subjected to severe discoloration over thousands of years,and red lead pigment discoloration is one of the most serious forms of discoloration in the pigment layer of the Dunhuang Mogao Grottoes murals.The reasons for the discoloration of red lead pigments and their stability in mixed pigments were reviewed and analyzed from the perspectives of photochemical reactions.And microorganisms,and the results showed that red lead pigment discoloration was mainly affected by ultraviolet light and microorganisms,and that mixed pigments of red lead pigments and cinnabar or iron red were more stable than red lead pigments.
