Portable propane-fired gold melting furnace designed for fast and easy melting of precious metals.
Suitable for small-scale melting of gold and silver.

Kit Contents :

• Hybrid kiln
• Bone ash cupels (4)
• Crucible tongs (8″)
• Cupel U tongs
• Graphite mini crucibles (2)
• Graphite loaf mold
• Melting flux (3 oz)
• Instructions for cupelling and metal melting

Working Principle :

• The kiln is heated using propane torches inserted through side ports
• The crucible inside is heated until metal melts
• A reduced environment is maintained to prevent oxidation during melting

Operation :

• Place furnace on fireproof surface
• Insert and ignite propane torches
• Preheat kiln
• Add flux and metal into crucible
