You can take it to the gold shop to identify the color. Gold shops are usually identified in two sections.
Identifying adulteration: 1. Whether there are white bright spots:
Cut the gold bar or gold jewelry with material scissors, observe its cut surface with a magnifying glass, if you see white bright spots, because ** and iridium cannot be fused together, it means that the ** is mixed with iridium.
2. Measuring specific gravity:
Measure the weight of a pure gold bar with a balance, then place the bar in a measuring cup and pour water over the bar. Then put the gold bar to be tested into the measuring cup, observe whether the scale of the water rises or falls, as long as it changes, it means that the gold bar is not pure gold. However, this method does not apply to gold jewelry, because there is air in it.
3. Real gold is not afraid of fire
Put the gold bars or gold jewelry on the fire for a while and observe the changes. Because iridium will oxidize with oxygen in the air, gold bars of insufficient purity will turn gray; Pure gold, on the other hand, will be red and shiny in color after being roasted by fire. However, this method may be destructive to jewelry.
