Detection of gold and trace elements in vintage gold jewelry
Vintage gold jewelry is a new type of pure gold jewelry,as a new craft and new product,it can meet people's special needs because of its diverse styles and high hardness.In order to study this product,the gold samples were tested and studied by X-ray fluorescence spectroscopy,ICP spectroscopy,fire assay and hardness tester.The results show that:due to the processing characteristics of retro gold jewelry and the variety of impurity elements,and the lack of suitable standard materials,X-ray fluorescence spectrometry analysis results are not ideal,ICP spectroscopy and fire assay can be used to detect.The hardness test results show that the hardness of retro gold jewelry is much higher than that of ordinary solid gold.
