摘要
翡翠的“无痕修复”是一种新型的拼合技术,使用胶类物质在真空高压的环境中渗透到拼接面达到拼接修复的效果。所谓“无痕”,即肉眼从外观几乎观察不到拼接痕迹。但通过常规宝玉石检测和红外光谱测试,能找到拼接证据:紫外荧光照射能观察到拼接面处的强蓝白色荧光,红外光谱能分辨环氧树脂的吸收峰。根据国标GB/T 16552-2017《珠宝玉石名称》,此类被“修复”的翡翠饰品应定名为拼合翡翠。
The“traceless repair”of Feicui(jadeite jade)is a new type of splicing technology,which uses adhesive substances to penetrate into the splicing surface in a vacuum and high pressure environment to achieve the effect of splicing and repair.The so-called“traceless”means that the splicing trace is almost invisible to the naked eye from the appearance.However,through conventional gemmological tests and infrared spectrum test,the splicing evidence can be found:the strong blue and white fluorescence at the splicing surface can be observed under ultraviolet fluorescence irradiation,and the absorption peaks of epoxy resin can be recognized by infrared spectrum.According to national standard GB/T 16552-2017 Gems-Nomenclature,this kind of“repaired”Feicui(jadeite jade)jewelry should be named as splicing jadeite jade.
