About this item

  • Natural High-Purity Graphite: The groove graphite crucible offers excellent high-temperature resistance and good thermal conductivity. It is less prone to deformation under heat and is specifically designed for electronic melting furnaces, making it easy to remove after use
  • 3KG Large Capacity: 334ML capacity, it can melt up to 6.4KG of gold, 3.5KG of silver, 3KG of pure copper, and 0.9KG of pure aluminum, making it ideal for smelting and casting precious metals
  • Not for Open Flame Heating: Pure graphite crucibles are not suitable for open flame heating such as propane furnaces or carbon furnaces. They are designed for use with electric furnaces, vacuum furnaces, or gas-protected furnaces
  • High-Strength Coating: The surface of the graphite crucible is coated with a dense glaze, which extends its service life. It is recommended to use one batch of material per crucible to avoid metal contamination. Always inspect the crucible before each use and replace it when necessary to maintain optimal performance
  • Groove Adaptation: The top of the crucible features a ring-shaped groove, making it easy to grip with tongs for pouring. This design ensures safety and stability, making it ideal for beginners in metal melting.
  • Customer Support: Our dedicated customer support team is available to assist you with any pre-sale or post-sale inquiries. Feel free to reach out to us directly through Amazon.
