TESTING OF COPAL RESIN AND AMBER

摘要: 在评述新西兰Kauri柯巴树脂与流浪的鉴别特征的基础上，根据鉴定实例，描述了柯巴树脂的常规宝石学特征、包裹体特征、红外光谱测试结果及其鉴定意义，指出酒精和红外光谱是准确区分柯巴树脂与流动的可靠方法，而常规宝石学常数和动植物包裹体作为鉴定依据则需要慎重使用。

Abstract: The dis tinction between N ew Zealand K auri copal and amber was reviewed. T hen the gemmo-logical characteristics, inclusions and infrared spectra of the tested copal specimens were studied. The results show that copal can be distinguished from amber by testing with alcohol and infrared spectrum， but physical properties such as SG, RI and fluorescence as well as inclusions must be used carefully in identification.
