摘要
一、对中国金丹术中"彩色金"的探讨 "彩色金"的化学组成是二硫化锡（SnS<sub>2</sub>）,欧洲人称它为"摩舍金"（mosaic gold）,是一种具有金黄色闪耀光泽的六角形鳞片状结晶。在西欧,当人们还没有掌握制取低锌黄铜粉的方法以前,它是最重要的一种金黄色颜料。而且直到近代,它仍然是重要的人工黄色颜料之一,人们常将它用胶调和以作金漆。它的发明和利用可能与中国、希腊。
In Chinese alchemy, mosaic gold (golden-yellow SnS_2 crystal) was prepared byseveral methods. This is perhaps a brilliant achievement of ancient Chinese empirical chemistry. The earliest record of mosaic gold appears in Sun Simiao's 'Tai Qing DanJing Yao Jue' (Tang Dynasty). His method is, at 'first, by heating a mixture of tinand orpiment (or realgar) ; then, by igniting product that tin and orpiment (or real-gar) had reacted with each other in a sealed crucible; finally, obtaining glitteringgolden-yellow hexagonal scales (SnS_2) and sublimate Arsenic crystal. Later, anotherprocess for making mosaic gold was described in the 'Ling She Da Dan Mi Jue-ZhuSha Dian Geng Fa' (Song Dynasty). The process consists of heating a mixture ofcinnabar and metallic tin in a sealed crucible. The method was further improved byChen Yuanjing in his 'Shi Lin Guang Ji' (Southern Song) by adding sal ammoniac.Through simulating test and X-ray diffraction analysis, the authors confirmed the factthat the product obtained by the above two methods is golden-yellow SnS_2.
