Usage Tips for Best Results

Pre-dry before first use: Quartz crucibles may absorb moisture during shipping. Before using, bake the crucible in an oven at approximately 150°C (302°F) for around 30 minutes to remove any trapped moisture.
Gradual preheating: Always preheat gradually and over a wider surface area before ramping up to high temperatures. This helps extend the service life of your crucible significantly.

Important Notes

Frequently Asked Questions

Q: What metals can I melt in this quartz bowl crucible?

A: This quartz crucible is suitable for melting and casting gold, silver, copper, and other metals commonly used in jewelry making and refining. Its 1800°C heat resistance accommodates the melting points of all common precious metals.

Q: Do I need to do anything before using the crucible for the first time?

A: Yes — because quartz material can absorb ambient moisture during shipping or storage, it is strongly recommended to pre-dry your crucible in an oven at 150°C (302°F) for about 30 minutes before its first use. This prevents cracking and extends the crucible's lifespan.

Q: How durable is the quartz crucible with repeated use?

A: With proper care — including gradual preheating and correct drying — this quartz crucible is designed for repeated, long-term use. Avoid sudden temperature shocks and always heat incrementally to maximize durability.

Q: Which size should I choose for my jewelry melting project?

A: Select a crucible capacity that closely matches the weight of metal you plan to melt. For small pieces or samples, 5g–20g sizes work well. For larger batches of gold or silver, the 50g–200g options provide ample capacity and control.
