A high quality crucible, best choice for melting larger and purer amounts of gold, silver, copper and bronze.
Made of fused silica with clay bond, for temperatures up to 2500°F (1371°C).
Must be pre-glazed before smelting (instructions included).
This size crucible fits inside the smaller GPK JR 7.5" kiln and can be used inside the regular 9.5" kiln - best to remove one of the 2" kiln layers.
Smelting time is much shorter than with the larger fused silica crucible; only around 30 minutes.
Dimensions: 3.5" wide x 3.5" high.
All prices are in Canadian funds but do not include tax and/or shipping (will be added where applicable)
