1.前言试金石是古代鉴定金银真伪和成色的工具和方法。它是现代分析化学中比色分析、研磨分析和无刨伤分析的始祖,属机械化学分析法。用它鉴定贵金属显得简便、快速、用样量少、结果比较可靠。所以,目前仍广泛用于贵金属收购行业中。这种古老方法虽有几千年的历史,但进展不大。本文仅对试金石的历史渊源作一简单探讨,并将其应用情况和使用方法作简略介绍。
1. Introduction Touchstone is the ancient identification of gold and silver authenticity and quality tools and methods. It is the colorimetric analysis of modern analytical chemistry, grinding analysis and no planing analysis of the ancestor, a mechanochemical analysis. Use it to identify precious metals is simple, fast, with less sample, the result is more reliable. Therefore, it is still widely used in the precious metals acquisition industry. Although this ancient method has several thousand years of history, it has made little progress. This article only makes a brief discussion on the historical origin of touchstone, and briefly introduces its application and usage.
