Laboratory porcelain fire assay crucible is a high-quality heat-resistant ceramic vessel designed for extreme temperature applications in laboratories and metallurgical testing. It is widely used in fire assay processes for precious metal analysis, including gold and silver extraction. Made from durable porcelain material, it offers excellent thermal stability, chemical resistance, and low contamination risk. The crucible can withstand repeated heating cycles in high-temperature furnaces without cracking or deforming. Its smooth inner surface ensures easy sample handling and cleaning. Commonly used in mining laboratories, research institutes, and industrial quality control, it provides reliable performance for precise analytical results.
