Ceramic Quartz Crucible Bowl for Melting Gold and Silver

Material: Utilizing fused silica as the primary raw material, this product is crafted using modern ceramic processing technology. Excellent Performance: Known for its high purity, resistance to corrosion, exceptional strength, ability to withstand high temperatures, and resilience against impact, this product is capable of sustaining temperatures as high as 2800 degrees. Extensive Applications: This product finds widespread utility in various fields such as electro-optics, semiconductors, optical communications, the military industry, metallurgy, construction materials, the chemical industry, machinery, electronics, environmental protection, among others. Usage Instructions: Prior to melting gold and silver, it is recommended to place borax at the base of the crucible to prevent the metals from adhering to the surface post-melting. The crucible is prone to moisture absorption, hence it should be preheated gradually before use to prevent water from freezing and causing damage. Package Contents: This package includes 2 pieces of 500g quartz silicon melting crucibles.
