Feature(may vary by option.)
●Material: fused silica as the main raw material, made by modern ceramic processing technology.
●Good performance: high purity, corrosion resistance, high strength, high heat resistance, high impact resistance, can maintain a high temperature of 2800 degrees.
●Wide application: widely used in electro-optical, semiconductor, optical communication, military industry, metallurgy, building materials, chemical industry, machinery, electrical, environmental protection and other fields.
●Usage: Before melting the gold and silver, borax should be placed at the bottom of the bowl to prevent the gold and silver from sticking to the bottom of the bowl after melting. The melting bowl is easy to absorb moisture, preheat and gradually heat before use to prevent the water from freezing and bursting.
●Package Includes: 2pcs 500g quartz silicon melting crucible.
