Product Q&A

Q:What is the purity of the fused silica crucible?

The SiO2 content is greater than 99.0%, with impurities (K2O, Na2O, Fe2O3) kept below 0.10%.

Q:What materials can be melted in this crucible?

It is mainly used for melting gold, platinum, dental alloys, gold, silver, brass, and copper.

Q:How should I prepare the crucible before use?

Dry it with low temperature before use. Preheat a large area before heating at high temperature and gradually increase the temperature.

Q:What is the recommended method to prevent sticking?

Sprinkle some borax on the bottom of the bowl and overfire. After melting, a thin film of crystals will form to prevent gold and silver from sticking.

Q:What is the compressive strength of the product?

The compressive strength at room temperature is greater than or equal to 70MPa.
