Testing and Naming of“Gold Inlaid Jade”
-
摘要: 为了科学的检测、正确命名“金镶玉”产品，避免错误的命名带来更多消费纠纷，使用能量色散、波长色散X射线荧光光谱仪(EDXRF，WDXRF)对“金镶玉”包金层含金量进行无损定量检测，并使用大型金相显微镜、扫描电子显微镜(SEM)对包金层厚度进行分离测量，结合X射线能谱仪(EDS)对包金层内部含金量进行半定量分析。通过实验发现所谓“金镶玉”实际是在塑料胚体包裹0.02～0.03mm左右的千足金层，使用胶体粘合在玉石表面。并对其科学命名提出了建议。Abstract: In this paper，energy dispersive and wavelength dispersive X－ray fluorescence spectrometer(EDXRF，WDXRF)are used for non－destructive quantitative testing for gold content of“gold inlaid jade”.And metallurgical microscope and scanning electron microscope(SEM)are used for the thickness of the gold layer after being separated from its jade base and X－ray energy dispersive spectroscopy(EDS)are also used for semi－quantitative analysis of the gold content of the gold layer.Experiment results show that the so－called“gold inlaid jade”is actually aplastic embryo wrapped in 0.02—0.03mm pure gold which is glued to the jade with colloid.The authors study on processing technology and testing methods of“gold inlaid jade”and give constructive suggestions on scientific naming of this product in order to avoid more consumer disputes resulted from incorrect naming.
