A: Yes, you can melt gold without flux. Pure gold, with a melting point of around 1064°C (1947°F), can be melted using a high - temp heat source like a propane - oxygen torch or electric furnace. Flux removes impurities and reduces oxidation, but if the gold is pure and oxidation isn't an issue, flux isn't needed. However, flux can enhance the melt quality when dealing with impure gold.
