The 1-2-3 Kg electric ovens are used in the goldsmith sector, specifically for melting, a process that consists in melting noble metals, such as gold and silver. The 1-2-3 kg ovens quickly reach a temperature of 1150 ° C. Inside them it is possible to place a graphite crucible with a capacity (in specific weight) of the single metals of 1, 2 and 3 kg. The ovens are complete with digital thermoregulator, graphite pliers and crucible, and, on request, with a heat protection grid and an analog thermoregulator.
