Clay Graphite Crucible #4 is the ideal tool for precise melting and casting of various metals, including gold, silver, copper, aluminum, and brass. Crafted from high-quality graphite material combined with refined clay, this crucible offers outstanding thermal conductivity, exceptional heat resistance, and robust mechanical strength for both professional jewelers and hobbyists.
Designed to withstand temperatures from 850°C up to 1600°C (1562°F to 2912°F), this crucible ensures uniform heat distribution for efficient melting and casting processes. Its durable construction minimizes oxidation and thermal shock, reducing the risk of cracking and extending the crucible’s service life even under repeated use.
With outer dimensions of 3.25 inches in height and 2.75 inches in diameter, and inner dimensions of 2.88 inches depth and 2 inches diameter, this #4 crucible provides a generous capacity of approximately 600 dwt (935 grams), accommodating up to 15.5 oz of gold or 12 oz of silver. Weighing about 1.25 lbs, it strikes a perfect balance between sturdiness and ease of handling.
The tapered design with a rounded base allows for smooth pouring, minimizing metal loss and ensuring safer transfer of molten metals. It is compatible with propane, gas, and induction furnaces, making it a versatile choice across different melting setups.
Whether you are involved in jewelry making, metal refining, or artistic casting, this clay graphite crucible delivers consistent, reliable results with every use. For maximum longevity, preheat gradually and avoid sudden exposure to open flames.
