Matters needing attention in identifying gold adulteration
1. Whether the gold has white highlights, cut the gold bars or gold jewelry with scissors, and observe the section with a magnifying glass. If you see a bright white spot, it means that gold is doped with iridium, because gold and iridium can't blend together.
2. To measure the specific gravity, first measure the weight of a pure gold bar with a balance, then put the gold bar into a measuring cup and pour water to drown the gold bar. Then put the detected gold bars into a measuring cup and observe whether the scale of water rises or falls. As long as there is a change, it means that gold bars are not pure gold. But if it is gold jewelry, this method is not applicable, because there is air in gold jewelry.
3, real gold is not afraid of fire, put gold bars or gold jewelry on the fire for a while and observe its changes, because iridium will combine with oxygen in the air to produce oxidation reaction, so the gold bars with insufficient purity will turn gray; Pure gold will be bright red after baking, but this method may cause some damage to jewelry.
