How do you heat up gold?

- The gold should be placed into a crucible.

- With a torch, hold the flame well above the gold powder and slowly work in a circular motion.
Can you melt gold with a heat gun?
The maximum flame temperature that can be obtained with propane gas is 3,595 degrees Fahrenheit (1,979 degrees Celsius). This is hot enough to heat a crucible and melt pure gold as well as gold alloys commonly used in jewelry.
Will gold melt in a fire?
Gold melts at a much cooler temperature – about 2,000 degrees Fahrenheit – but that’s enough to survive most house fires. Platinum jewelry is the priciest, so it’s a good thing that the metal’s melting point is just higher than 3,200 degrees Fahrenheit. Sapphire and Ruby also possess extremely high melting points.
Does melting gold purify it?
Does melting the gold purify it? Yes. In fact, melting is the oldest method to purify gold with fire. However, since the melting temperature of gold is 1064 degrees centigrade, melting at this point leads to high risks of severe burns.
