The process of smelting gold requires a furnace, microwave kiln, or torch.
Melting means to change something from a solid to a liquid by the application of heat.
When the heat is removed, the melted material returns to its solid state.
Its chemical content has not been changed..

How do you refine pure gold?
It is possible to refine gold without the use of large-scale, expensive chemical procedures. The process involves first adding nitric acid to gold, then adding hydrochloric or muriatic acid. After allowing this mixture to sit, it is filtered to remove contaminants, then treated to neutralize the acids in the solution.

Does gold melt easily?
Most metals have very high melting points, not least gold—which turns into a liquid at temperatures above 1,947 degrees Fahrenheit (1,064 degrees Celsius). But now, researchers from Chalmers University of Technology in Sweden have found a way to melt gold at room temperature.
What temp does gold burn?
Gold has a very high melting temperature of 1,943 degrees Fahrenheit (1,062 degrees Celsius). This means that the melting of gold can only be achieved with flames that reach this temperature.
How quickly does gold melt?
1948FGold melts at ~1948F. Lead melts at ~621F. Wood goes through several stages before burning.
How can we increase the purity of gold?

Can you melt 14k gold at home?
Try using a propane torch to melt gold. The gold should be placed into a crucible. Then, put the crucible on a fireproof surface, and direct a torch toward the gold within the crucible. If you add the chemical borax to the gold first, you can melt it at lower temperatures, which might be needed if you’re using a torch.
