Crucibles and Molds for Gold Smelting

Graphite Crucibles

Graphite crucibles are made of a graphite/carbon compound and have the ability to handle the higher temperatures required to melt gold. The graphite prevents the gold adhering to the insides of the crucible after melting making it easier to pour into a mould. Typically graphite crucibles are used in smelting furnaces.

1    250g    Capacity 55x50mm    $23.50
2    500g    Capacity 65x55mm    $26.50
3    1.5kg    Capacity 85x70mm    $47.00
4       2kg    Capacity 90x80mm    $52.00

Clay Crucibles

Clay crucibles

are made of white clay and used for smelting and alloying metals such as gold or silver. Typically clay crucibles are used by jewellers or prospectors wishing to melt raw gold into buttons using a torch.

1    100g Capacity    50x50mm    $9.50
2    300g Capacity    70x70mm    $10.50
3      1kg Capacity 100x100mm   $17.50

Gold Molds

are made of cast iron and used to make gold bars. The gold is poured directly into the gold mold from the smelting crucible. When the metal has cooled, the gold bar is turned out, just like a cake.
Special consideration has to be given to the molds preparation prior to use so that the gold comes out cleanly without sticking or fusing to the mold. Casting molten metals requires a methodical approach and due to safety issues only experienced operators should attempt this.

Molds come in different capacities. We stock a 10 Oz mold $39.00
