Real, pure gold, when exposed to the flame, will get brighter after a while as it gets hotter, but will not darken. Fake gold pieces, such as fool’s gold (actually pyrite, an iron sulfide) and pieces made of brass, iron or copper alloys will darken or otherwise change color when exposed to fire.

What will happen if you burn gold?

Real, pure gold, when exposed to the flame, will get brighter after a while as it gets hotter, but will not darken. Fake gold pieces, such as fool’s gold (actually pyrite, an iron sulfide) and pieces made of brass, iron or copper alloys will darken or otherwise change color when exposed to fire.
