Ceramic Crucible (Melting Dish) for Precious Metal Casting & Refining

This high-temperature ceramic melting dish is designed for jewelers, refiners, and metalworkers performing torch-based melting, casting, and refining of precious and non-ferrous metals.

Constructed from dense, heat-resistant ceramic, this crucible withstands repeated high-temperature use while maintaining structural integrity. The smooth interior surface promotes clean metal flow, and the textured exterior provides a secure grip during handling. An integrated pouring lip allows for controlled, accurate pours with reduced spillage and metal loss.

Key Features

High-temperature ceramic construction

Smooth interior for improved metal flow

Textured exterior for safer handling

Integrated pouring lip for controlled pours

Suitable for gold, silver, copper, and other non-ferrous metals

Pro Tip: Season Before First Use (Strongly Recommended)

Seasoning helps prevent metal from sticking and significantly extends the life of the crucible.

How to season:

Add a small amount of borax (sodium borate) powder to the dish

Heat gently with a torch until the borax melts into a clear, glassy coating

Tilt and rotate to coat the entire interior, including the pouring lip

Allow to cool completely before use

This creates a protective glaze that improves metal flow and protects the ceramic.

Intended Use

Jewelry casting and alloying
