埃及文明在矿物方面的知识总是超出了我们的想象。这方面就包括使用多种黄色矿物绘制颜色相近的色彩。对这些颜料的准确鉴定将拓展人们在彩画方面的研究。画家所使用的颜料非常丰富,除了同时代直接从埃及地面采集的自然颜料外,还有大量像埃及蓝这类合成颜料的应用。对法国的这些藏品的研究将使人们可以追溯几个世纪以来这些颜料的演变和替代过程以及一些从其它地区尤其是东方国家引进颜料的过程。一些颜料的稳定性及其它特性使得其保存状况令人惊讶。卢浮宫博物馆在塞加拉的任务是进行一个埃及晚期(公元前378年-公元前341年)典型群葬墓的发掘工作。发掘出的木质棺材上记载了该墓葬的埋藏时间是Nectanebo二世法老执政的第2年,这是埃及第三十王朝的最后一任法老。该研究涉及以木质为基材的出土物,它包括二十个完整的或破碎成碎块的像盒子一样的棺材。研究通过在双筒显微镜下对文物进行微量取样,而后将样品进行扫描电子显微镜-能谱分析以及显微拉曼光谱分析,从而确定样品中矿物的成分。此外还对样品进行微量化学分析以确定其残存的痕量胶料。彩色颜料包括埃及彩画同时代的传统颜料——黑色,白色,红色,黄色,蓝色,绿色和镀金,同时还包括一些不常见的粉红色或橘色颜料,它是一种外来的、易碎的颜料,成分为五硫化二砷,又称雄黄。
Knowledge of minerals in Egyptian civilization has always exceeded our imagination. This includes the use of a variety of yellow mineral color rendering similar colors. The accurate identification of these pigments will expand people’s research in color painting. The paints used are very rich in pigments, in addition to natural pigments collected directly from Egyptian soil in the same period, there are a large number of synthetic pigments such as Egyptian Blue. Research on these collections in France will allow one to trace the evolution and replacement of these pigments over centuries and the process of introducing pigments from other regions, especially from the East. The stability and other characteristics of some pigments make their storage surprising. The mission of the Louvre Museum in Saqqara is to excavate a typical group of burials at the end of Egypt (378 BC - 341 BC). The excavated wooden coffin records the burial time of the tomb as the second year of pharaoh Nectanebo II, the last Pharaoh of Egypt’s thirtieth dynasty. The study involved a wood-based excavated material that included twenty complete, or fragmented, box-like coffins. The study determined the composition of the minerals in the sample by microscopic sampling of artifacts under a binocular microscope followed by scanning electron microscopy-energy spectrum analysis and microscopic Raman spectroscopy. In addition, the sample was subjected to microchemical analysis to determine the amount of residual traces of the compound. Color pigments include traditional Egyptian contemporary paints - black, white, red, yellow, blue, green and gold, as well as some unusual pink or orange pigments, it is an exotic, easy Broken pigment, arsenic pentasulfide composition, also known as realgar.
