摘要
韩休墓壁画作为典型的唐代墓葬壁画,其颜料表征及加固剂对色度的影响亟待研究。使用基恩士VHX-5000超景深三维显微系统、X-rite VS450色度仪等检测仪器对韩休墓出土的玄武图残块进行了表面观察,同时分析了两种加固剂对其色度的影响。研究发现玄武图中黄色颜料为钒铅矿与铅丹混合使用,铅丹氧化产生的碳酸铅在实验室环境下被进一步氧化为氧化铅。色度方面,研究表明实验室目前使用的两种加固剂对壁画中出现的5种颜色色度影响ΔE值不超过4.33,符合良好标准。
In this study,the Keyence VHX-5000 ultra-depth three-dimensional spectrophotometirc system,the X-rite VS450 colorimeter and other related instruments were used to conduct surface observations and chromaticity monitoring on samples of Xuan Wu mural painting unearthed from the Tang Dynasty tomb of Han Xiu.The study found that the yellow pigment in the mural is a mixture of vanadium-lead ore and lead.The lead carbonate produced by the oxidation of lead in the tomb was further oxidized to lead oxide in the laboratory environment.With regard to chromaticity,research shows that theΔE value,which shows the difference in chromaticity before and after reinforcement,is around 4.33,which is within acceptable standards.
