摘要
藏传颜料的使用具有悠久的历史,其作为物质与非物质文化载体而越来越受到关注。文章利用体视显微镜、拉曼分析(RS)、X荧光分析(EDXRF)等现代仪器分析技术,对几种常见藏传颜料进行成分分析,结果表明测试样品均为天然矿物颜料。其中,淡绿色颜料为石绿;两种蓝色颜料均为石青,由于纯度和提取方法的不同,使其在色度上有一定的差异;土黄色颜料由铁黄作为主色调色而成;黄、橘色颜料分别为雌黄和雄黄;红色颜料为朱砂。研究工作还显示,拉曼光谱法、X射线荧光光谱法和体视显微镜方法的结合能够完成藏传颜料的分析工作,且在文物颜料的无损与微损分析方面具有广阔的应用前景。
The application of Tibetan traditional pigments has a long history. It has also attracted more and moreattentions as a carrier of material and non-material cultural heritages. In this study, the component of seven Ti-betan traditional pigments samples were analyzed by Stereomicroscope,Raman Spectroscopy（RS）, and X-rayFluorescence Spectroscopy（EDXRF） methods. The analyses indicated that they were all natural mineral pig-ments, and chromogenic green pigment was malachite greenl green, two blue pigments were azurite, but some dif-ferences in their color exited because of purity and different extraction methods; the khaki pigment was iron ox-ide yellow, the yellow pigments were orpiment and realgar, and the red one was cinnabar. The study also revealedthat the use of Stereomicroscope, RS and EDXRF methods could basically complete the pigments analysis, and ithad an advantage in analysis of non-destructive or micro-damage heritage pigment.
