Resistance <strong>Melting</strong>All resistance melters use some kind of hightemperature wire (like the wire in lightbulbs) wound into a spiral outside thecrucible.When electricity moves through the wire,the wire offers resistance to the electricityand becomes hot enough that the heatradiates through the crucible to heat themetal.18
Resistance <strong>Melting</strong> Cont’dThis type of melting provides the bestmeans of temperature control and can beused for all types of Crown and Bridgealloys.It also offers a choice of crucibles, carbonfor high gold alloys and ceramic (and flux)for palladium alloys.19
