Jul 17, 2009 gold is an EXCELLENT conductor of heat, so if you are planning on melting a large amount of gold, use a kiln. Jewelers use a tiny torch to melt gold, but they only melt a tiny bit at a time the gold has nowhere to conduct the heat away. If a jeweler tried to melt a bar of gold with the same tiny torch, he would just waste his time.
