1, bite method:
When identifying the authenticity of gold, you can bite the gold properly and observe whether there are bite marks on the surface of gold. Theoretically, gold will leave a bite mark after being bitten. The deeper the bite mark, the higher the purity of gold.
2, magnet attraction method:
Magnets can be used to attract gold. Gold is not a magnetic metal. If a magnet can attract gold, it must be fake. At the same time, it may not really be attracted by magnets, but it may also be made of other non-magnetic metals.
3, scraping porcelain plate method:
You can find a porcelain plate and scratch it with gold. If black scratches are left on the surface of the porcelain dish, this kind of gold is not real gold. If the scratch is gold, it is real gold.
