Abstract

Abstract This paper discusses pigments used in Indian palm leaf manuscripts. Formerly it was believed that pigments for palm leaf illustrations were mostly sourced from plant extracts – a believe that is still widespread in India. This paper reports the identification of pigments of an illustrated palm leaf manuscript (eighteenth – nineteenth century) collected from the east coast of India. As Raman spectra of many pigments gave too high background noise, the identification was mostly accomplished through SEM-EDX and FTIR spectroscopy. The analytical findings indicated that both mineral colours and plant extracts were sourced for Indian palm-leaf manuscripts. Analysis indicated the use of lamp black for black, indigo for blue, vermillion for red, orpiment for yellow, china clay for white and a mixture of orpiment and indigo for green coloration in the illustrations. The data has improved our knowledge of historic pigments used in palm leaf illustrations. As some of the pigments are either photosensitive or darken due to atmospheric pollution, necessary preventive conservation measures need to be adopted.
用SEM-EDX等技术研究18 - 19世纪印度棕榈叶手稿上的颜料
摘要本文讨论了印度棕榈叶手稿中使用的颜料。以前,人们认为棕榈叶插图的颜料主要来自植物提取物——这种观点在印度仍然很普遍。本文报道了一份从印度东海岸收集的18 - 19世纪棕榈叶手稿的颜料鉴定。由于许多颜料的拉曼光谱具有较高的背景噪声,因此主要通过SEM-EDX和FTIR光谱进行鉴定。分析结果表明,矿物颜色和植物提取物都来自印度棕榈叶手稿。分析表明,在插图中使用了灯黑代替黑色,靛蓝代替蓝色,朱砂代替红色,黄粉代替黄色,瓷土代替白色,黄粉和靛蓝的混合物代替绿色。这些数据提高了我们对棕榈叶插图中使用的历史颜料的认识。由于部分色素因大气污染而光敏或变暗,需要采取必要的预防性保护措施。
