Clay Graphite Crucible #1 is expertly engineered for melting and casting a wide range of non-ferrous metals. Whether you’re refining gold, silver, copper, brass, or aluminum, this crucible offers the durability, efficiency, and precision that professionals demand.

Clay graphite crucibles are made from a premium mix of clay and graphite, combining the thermal shock resistance of clay with the high conductivity and strength of graphite. This synergy ensures excellent performance in high-temperature applications, particularly where metals are prone to oxidation or contamination.

This #1 crucible features a capacity of 120 oz. or 3,732 grams of 18K gold, making it perfect for small to medium melting jobs. It can withstand temperatures between 850°C and 1600°C (1562°F – 2912°F) without cracking or deforming, ensuring clean, consistent results across multiple uses.

With outside dimensions of 4" diameter x 4.38" length and inside dimensions of 3" diameter x 3.75" depth, this crucible is well-suited for both torch and furnace melting setups. The smooth inner walls enable clean metal pours, reduce slag buildup, and prevent material waste, which is especially important for high-purity casting.

Thanks to its high refractoriness, low porosity, and excellent chemical resistance, this crucible protects your melt from atmospheric contamination and prolongs crucible life. It performs exceptionally well even under rapid temperature changes and demanding workshop conditions.

This professional-grade crucible is widely used by jewelers, metalsmiths, refiners, and casting technicians who prioritize quality and efficiency in every melt.
