摘要
采用火试金方法测定14K金首饰中的金含量,主要研究了标准金称样量、铅球形状、灰吹过程及分金温度等对测试结果的影响,最终确定了最佳的测试条件,并保证了实验的准确度和精密度。
Gold content of 14K gold jewelry was measured by fire assaying method. The influence of standard gold sample weight, lead ball shape, cupellation process and parting temperature on the testing result were mainly studied and the optimal test conditions have been ultimately established and the accuracy and precision of the experiment are guaranteed.
