Gold Melting Electric Furnace

The furnace used for melting gold bullion is of simple construction. It may be round or square, with walls consisting of an outer layer of ordinary brick and an inner layer, at least 4 inches thick, of the best firebrick.They use coiled heating elements embedded within a crucible or integrated into the walls of the heating chamber itself. These convert electrical energy into heat which is radiated through the material with outstanding degrees of thermal uniformity.
