一种仿软玉“新型玻璃”的宝石学研究

Study on Gemmological Characteristics of a New Type of Glass: a Kind of Imitative Nephrite

"新型玻璃"是最近软玉批发市场上出现频繁的一种冒仿软玉的产品,其特点是外观很像软玉,而且其红外图谱谱形极像软玉的,个别峰位基本吻合,这给软玉的快速鉴定带来了一定的迷惑性和风险。选取一批典型的"新型玻璃"进行常规宝石学测试和红外光谱测试等一系列宝石学研究。测试结果表明,虽然"新型玻璃"的红外图谱谱形极像软玉的,但是两者之间的性质还是有着明显的差别,依据现行国家标准,其鉴定名称可直接命名为"玻璃";同时,对"新型玻璃"的快速鉴定提出了一些参考建议。

A new type of glass is a kind of imitative nephrite, which often appears in the nephrite wholesale market. The appearance of the new type of glass resembles nephrite and its infrared mapping spectrum is almost similar to that of nephrite, which results in some dif- ficulties and risks in the fast identification of nephrite. The present paper investigates the gemmological characteristics of the new type of glass by using routine gemmological testing and infrared spectroscopy testing. The results show that the new type of glass is quite differ- ent from nephrite in nature though its infrared mapping spectrum is almost similar to that of nephrite. According to the current national standards, its identification name can be directly named glass. At the same time, this paper puts forward some suggestions for the fast identification of this new type of glass.
