真金不怕火炼黄金与其他具有金黄色金属光泽的固体(如黄铜及黄铜矿、黄铁矿)的简易鉴别方法是:高温灼烧.这是因为金的化学性质很不活泼,即使加热至熔化(熔点为1064℃)也不与空气中的氧气或氮气等反应,依然能保持金光闪闪而不变质;而黄铜等金黄色物质经不住烈火的考验而变质、变色.因此,常用“真金不怕火炼” The real gold is not afraid of gold and other bright golden metallic luster solid (such as brass and chalcopyrite, pyrite) simple identification method is: high temperature burning.This is because the chemical properties of gold is very lively, even if Heated to melt (melting point of 1064 ℃) nor with the air of oxygen or nitrogen and other reactions, still able to maintain the bling without deterioration; and brass and other golden yellow material can not stand the test of fire and deterioration, discoloration.Therefore, Commonly used “real gold is not afraid of fire refining”
