Quartz Ceramic Crucible Set for Melting Gold and Silver

This ceramic quartz crucible is perfect for melting materials with the torch method. Designed with tapered sides and pouring ports, it allows for easy material removal and is suitable for melting precious metals such as gold, silver, bronze, copper, and brass at temperatures of up to 2800°F. It is made of fused silica as the main raw material, utilizing modern ceramic processing technology.

This crucible boasts high purity, corrosion resistance, high strength, heat resistance, and impact resistance, allowing it to maintain a temperature of 2800 degrees. It finds wide applications in various fields including electro-optical, semiconductor, optical communication, military industry, metallurgy, building materials, chemical industry, machinery, electrical, and environmental protection.

For optimal use, place borax at the bottom of the crucible before melting gold and silver to prevent sticking. The crucible is prone to moisture absorption, so preheat it gradually before use to avoid water freezing and bursting.

The package includes 2 pieces of 750g quartz silicon melting crucibles.
