Product Description

Ceramic Heat Resist Assay Muffle Furnace Gold Fire Clay Crucible

Product Performance-Oriented (Laboratory Application )

For precise precious metals analysis in laboratories, only the highest-quality fire assay crucibles will do. We are a leading manufacturer specializing in crucibles engineered for mining, metallurgy, and lab analysis scenarios. Each crucible is crafted with cutting-edge production techniques and undergoes strict quality inspections to ensure superior thermal stability—withstanding extreme temperatures without deformation, excellent corrosion resistance against harsh reagents, and consistent analytical accuracy that meets the most stringent lab standards. Trust our crucibles to deliver reliable results for your critical precious metals testing workflows.

Type: Refractory Material

Working Temperature: 
≥ 1350ºC(Fire assay working temperature less than 1150ºC)
No cracking when moved from 1100°C furnace directly onto a room-temperature steel plate.
Chemical Corrosion Resistance:
Highly resistant to corrosive fluxes like litharge, borax, and silica, maintaining integrity during the critical initial 3-5 assay cycles.
Accuracy & Low Retention:
Made from high-quality clay, crucible ensures minimal retention of precious metals for easy recovery and accurate result.
Structural Stability:
Our fully automated production lines ensure consistent quality and stability in every batch.
