5 FAQs of Ceramic Alumina High Back Crucible Dish Cup for Melting Casting Refining Gold Silver Copper Scrap Metal Jewelry

Ceramic Alumina High Back Crucible Dish Cup: 5 FAQs

What is this crucible for?
This crucible melts metal. It works for gold, silver, copper, scrap metal, and jewelry making. The high back design helps contain molten metal safely. It prevents dangerous spills. It handles high heat well.

Why ceramic alumina?
Ceramic alumina is super tough. It handles extreme temperatures easily. It won’t crack easily from sudden heat changes. This material resists chemical reactions. Your melted metal stays pure. It lasts much longer than cheaper graphite or clay crucibles.

How hot can it get?
This crucible handles very high heat. It withstands temperatures up to 2300°F (1260°C). This is hot enough for melting most precious and non-ferrous metals. Always check your specific metal’s melting point first. Never exceed the crucible’s rated temperature.

Is it safe for direct flame?
Yes. You can use this crucible directly in a furnace or torch flame. It’s designed for direct heat contact. The ceramic alumina material handles direct fire well. It won’t break down quickly. Always use proper tongs and safety gear. Molten metal is extremely dangerous.

How long does it last?
Lifespan varies. It depends on usage intensity and temperatures reached. Using it correctly makes it last longer. Avoid sudden temperature shocks. Don’t drop it. Don’t overheat it. Don’t pour cold metal onto a hot crucible. With careful use, expect many melts before needing replacement. It’s much more durable than basic alternatives.
