How to distinguish real gold from fake gold?
In daily life, some people count some simple ways to distinguish gold as a small formula: weighing, looking at color, judging rhyme, folding hard and soft, and using acid points. It can be divided into the following small methods: \r\n\r\n 1. Real gold is softer than other metals. So gold can be folded directly by hand. If you can bend directly by hand, and it is easy to bend continuously, it will appear soft. Moreover, there will be traces when real gold is scratched by hard objects. \r\n2。 Listen to the sound. Real gold with a purity of more than 99% will beep when thrown on the hard ground, which is disorganized and elastic. Fake or low-quality gold sounds crisp and dull, generally making a "Dangdang" sound, with a lingering sound, and violently beating after landing. \r\n3. True color is dark yellow, excessive dividends are fake gold, and light color is mixed gold such as silver and aluminum. The higher the purity of gold jewelry, the darker the color. \r\n4。 The same volume of gold is more than 40% heavier than silver, 1.2 times heavier than copper and 6. 1 times heavier than aluminum. The same volume, really heavier, fake lighter. \r\n5。 Burn the jewelry to be identified (don't make it melt and deform), and observe the color change after cooling. If the surface is still golden, it is pure gold; If the color darkens or turns black to varying degrees, it is not pure gold. Generally, the lower the fineness, the thicker the color, and all of them turn black, indicating that they are fake gold ornaments. \r\n\r\n6。 Look at these signs. Under normal circumstances, there are always some signs behind the gold ornaments. Domestic gold ornaments are purified and prepared according to international standards, and stamped with seals, such as "thousands of gold" or "pure gold". These marks can be used to distinguish the authenticity of gold ornaments.
