Fire assay is the quantitative determination of precious metal content in ores and metallurgical products by melting with flux. This method has the advantages of good sampling representativeness, wide applicability and good enrichment effect. It is an important means for the chemical analysis of gold, silver and precious metals. Clay crucible as a fire test vessel, has the characteristics of high temperature and corrosion resistance, can be reused for 5-7 times.
