用吹管分析鑑定礦物或做次管分析实验时,要用質量較好的无裂缝的木炭。这种木炭价錢很貴,而且又很缺乏,市場上不易買刮。另外用木炭來做这个实驗很不清潔。因而筆者用砖和瓦片代替木炭做实驗,經过試驗証明砖瓦不僅能耐很高的溫度,而且效果也很好。升華物、硫肝及金屬球等反应在砖上都做成功了。在試驗前筆者以为木炭是还原剂有助于还原反应,因此恐怕用磚做还原反应——金屬球不能成功,但經过試驗証明在砖上亦可得到还原反应。
The use of pipe analysis to identify minerals or do secondary analysis experiments, the use of good quality crack-free charcoal. This kind of charcoal is expensive and very scarce. It is not easy to buy scraps on the market. In addition to charcoal to do this experiment is not clean. Therefore, I use brick and tile instead of charcoal to do the experiment, after tests prove that brick and tile not only can withstand high temperature, but the effect is also very good. Sublimation objects, sulfur liver and metal balls and other reactions are done on the brick success. Before the experiment, I thought that charcoal is a reductant to help reduce the reaction, so I am afraid to use the brick to do the reduction reaction - metal ball can not be successful, but after the experiment proved that the reduction can be obtained on the brick.
