火试金法的历史可以追溯到古埃及时代,且一直是人类熟知的最好的试金法。但在科技迅速发展的近400年来,火试金法尚未有多大的变化,在当代,如果一种方法总停留在“技艺”的水平上是远远不够的。所以,有必要对该法中的诸多变量或因素定量化,从而使火试金法成为一门科学。本文旨在揭示怎样控制标准分析中造成的金银损失,怎样使主观判断成分降至最小,怎样提高和确保分析精度。通过利用改制的家用微波炉,我们将古老的炉前操作变成了一种象烧牛肉一样简单的按电钮的干净简便的操作。
The history of the fire test dates back to the ancient Egyptian era and has been the best test method known to mankind. However, in the nearly 400 years since the rapid development of science and technology, there has not been much change in the fire test method. In the contemporary era, it is far from enough if one method always stays at the level of “artistry”. Therefore, it is necessary to quantify many of the variables or factors in the law, thus making the fire trial a golden rule a science. This article aims to reveal how to control the loss of gold and silver in the standard analysis, how to minimize subjective judgments, how to improve and ensure the accuracy of analysis. By using a rebuilt home microwave oven, we turned the ancient stove-front operation into a clean and easy-to-use push-button operation that is as easy as burning beef.
