Why Your Fire Assay Crucibles Crack: Solving Thermal Shock Issues

Fire assay remains the gold standard for precious metal analysis. However, even well-run laboratories frequently face a costly and frustrating issue: cracked crucibles. In most cases, premature failure of fire assay ceramic products is not caused by defects, but by crucible thermal shock. Understanding why fire assay crucibles crack—and how to prevent it—helps laboratories reduce […]
