  1. bake with alcohol lamp
    after gold jewelry comes into contact with mercury, it will form small white spots on the surface. You can light the alcohol lamp, and then aim the position of gold jewelry with white spots at the alcohol lamp for baking. The temperature of the alcohol lamp can remove the white spots on gold, but the melting point of gold is high, so it will not affect the gold jewelry.
