What is burning gold?

Professional muskets should be used to burn gold, and the temperature must be above 1000 degrees, otherwise it will be bad for gold.

Reason:

Because the melting point of gold is really not high. However, gold has a high chemical stability and is not easy to react with other substances, so there is no need to worry about oxidation and discoloration. Even in the molten state, it will not be oxidized and discolored, and it will still be golden yellow after cooling. At the same time, the volatilization of gold in molten state is very small and can be ignored. Therefore, even if gold is melted, the gold nugget obtained after cooling is the same color and weight as that before combustion, and there is no oxidation loss.
