摘要
针对目前市场上田黄石与其仿制品真假难辩的问题,研究出一种能快速、准确地鉴别出田黄石真假的方法,通过采用显微鉴定—粉末油浸法,充分利用4种仿制品主要矿物成分的光性特征与田黄石有较大不同,达到识别田黄石与其仿制品的目的。研究认为,在显微镜下的鉴定中,准确地测定折射率是最关键的。
Aimed at the difficulty of telling the true Tianhuang stone from the imitation on the present market, a method of quickly and precisely identifying the true Tianhuang stone from the mimic has been developed. By using microscopic identification-powder oil immersion method, it can be found that the main mineral components of 4 kinds of imitation are quite different from Tianhuang stone so one can tell the true Tianhuang stone from the imitations by full use of the characters. It is believed that precise determination of refractive index is a vital importance to the microscopic identification.
