XING TAL LONG
We supply high quality , multi-use Fire Assay Crucibles, Ashes Assay Crucibles and Scoriiers for the analysis of Precious Metals (Gold, Silver, and Platinum Group Metals) using the Fire Assay / Cupellation method (“Docimasy”). Platinum group metals include: ruthenium, rhodium, palladium, osmium, iridium, and platinum.
FIRE ASSAY CRUCIBLES are used to prepare the lead button, including the precious metal sample, for cupellation. These crucibles combine a high mechanical strength and erosion resistance with an ability to withstand severe thermal shocks from the assay furnace. The inclusion of fused silica in the mix enhances the TSR.
