摘要
为了有效鉴别琥珀及其仿制品,本文收集了一系列琥珀及其仿制品。首先采用常规宝石学方法,对其折射率、相对密度、紫外荧光和内外部特征进行了测试;在此基础上,采用反射法测试了所有样品的红外吸收光谱并对其进行了比较和分析。结果表明,将常规宝石学方法和红外吸收光谱特征结合并综合分析,可以有效鉴别琥珀、压制琥珀、天然柯巴树脂、人工树脂及人造琥珀。
A few standard gemological indexes such as refractive index,specific gravity and ultravoilet fluorescence were tested together with infrared absorbance spectra.the results show that they are available in identifying the natural ambers,reconstructed ambers,copal resins,synthetic resins and artificial ambers
