莫高窟232、35窟壁画颜料的分析和讨论

Analyses And Discussion On Pigments of Mural Painting In Cave 231 And Cave 35 In Mogao Grottoes

一、概述对莫高窟壁画颜料的分析,以前只进行过局部取样分析。这种分析不能准确反映壁画颜料使用情况,对一些用量小且只在局部出现的颜料会造成漏测,这样给研究工作带来一定的困难。在以前分析的基础上,为了取得整窟壁画颜料分析经验,利用与外单位合作保护敦煌石窟的机会,我们选定了两个洞窟进行分析实验,以求取得经验后对莫高窟壁画颜料进行全面的分析。

This paper expounded that pigments of mural painting were analyzed by X-ray diffraction and microscope in cave 232 and cave 35. The paper emphasised to make an analysis on such pigments as white, red, green, black-brown. The analysis results indicated.. 1) Using white pigment were different in different dynasties. 2) We found that minium not only had been turned into plattnerite but also cinnabar had been changed metacinnabar. 3) We thought discolouring of minium concerned with environment (especially humidity), manufacturing materials for mural painting, because we discovered some mural painting where were more wet, more salt discloured seriously.
