Method:
Color discrimination. Look at the appearance color of gold, commonly known as "seven green, eight yellow, nine five red". Pure gold will shine brightly in strong light, which is not available in other metals (including copper).
Second, weigh it. Gold has a large proportion, which is about twice as heavy as common metals such as copper, silver, lead and zinc. It feels heavy in your hand, and its shape is big and light, which may be adulterated.
Triple property. Hand-folded gold ornaments, soft HD gold; Low purity is not soft. Small pieces of gold ornaments have flexible hands, high color and clear gold are soft, and there are wrinkles at the folds; Low color is hard, elastic, fragile and easily broken.
When two identical gold ornaments collide, the high color will make a "Bubu" sound, the low color will make a "jingle" sound, and the mixed gold will make a "jingle" sound. You can also throw it on the table or on the ground and try to tell it apart. When real gold is thrown on the ground, it will make a "poop" sound, commonly known as the sound of death. Low-quality gold ornaments are thrown on the concrete floor with rhyme, sharp voice and slight rebound.
Five exams are difficult. A few strokes with a pin or nail, the trace is obviously gold, and the trace of copper is slightly worse.
Reminder: there is no way to test gold if someone bites his teeth and leaves teeth marks.
