Fire assay its a classical analytical method for applying metallurgical principles and techniques to analytical chemistry. To test the content of precious metals in minerals and metal products determined by melting and roasting. The method has the advantages of good sample representation, wide applicability, good enrichment effect and so on。

"Jintuo" brand fire assay crucible using high alumina bauxite,mullite, kaolin as raw material with modern mechanical processing to suppress the crucibles, very low content of gold and silver elements can make the test results more accurate. Widely used in mining laboratories, metallurgical plant ,and other areas of metal sample analysis.
