1. One of the fastest ways to identify the fastest of the authenticity of the gold in gold. The proportion of gold and other precious metals is about 19-32, so gold is heavy than metals such as silver, copper, lead and other metals. 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. Therefore, the gold jewelry should have a feeling of sinking in the hand. This method is not applicable to gold jewelry inlaid with gemstones. 2. Look at the color method The higher the purity of the gold jewelry, the darker the color. We can determine the general color of gold according to the following colors: The color of the golden yellow golden purity of the color is more than 95 %, the purity of light red yellow is 90--95 %, and the purity of light yellow is 80--85 %, The purity of the cyan yellow is 65-70 %, the color of the white light is only 50--60 %, and the slightly yellow and white purity is less than 50 %. Pynasia, the Qiqing, Eight Huang, and Jiu Chi can be used as a reference for identifying the authenticity of gold. The fastest way to identify the authenticity of gold and falseness is the above -mentioned weight method and the color method. Of course, we have many other fast methods to identify the authenticity of gold. It is recommended to understand more and compare more.
3, magnet test This is a simple test, but it is not a sufficient proof to prove whether it is true gold. You can find a powerful magnet for testing. Gold is not a magnetic metal. If your product is attracted by magnets, it is enough to prove that this product is not gold. But you can't prove that it is gold because your product does not respond to magnets, because there are many non -magnetic metals. 4, bite test everyone has watched movies, and the mininger bite gold to test it. I also saw that when the Olympic athletes won the gold medal, they would bite their "gold" medal. How simple this test is. In a gently bite to check your bite marks. The deeper the bite marks, the higher the purity of the gold. The expansion information: 1. Whether the gold has white highlights In the material cutting the gold bar or gold jewelry, and observe the cut surface with a magnifying glass. Together, it means that the gold is mixed with 铱. 2, measured the proportion. In the weight of a pure gold bars with an balance, and then put the gold bars into a measuring cup and flood the gold bar. Then put the detected gold bars in a measuring cup, whether the scale of the water rises or decreases. As long as it changes, it means that the gold bar is 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. This gold bars or gold jewelry burned for a while to observe its changes. Because the oxidation reaction occurs with oxygen in the air, the gold bars with insufficient purity will become gray; and the color of the pure gold will be red after the fire is baked. However, this method may be destroyed to jewelry. Reference materials Source: Baidu Encyclopedia-Gold Differential Mixed Mixed Mixed
It can be simply judged by several methods: 1 The density of gold is more than double the density of copper, and a little experience can be distinguished by weighing. 2 Gold is soft, it is easy to bend and deform, it will not rebound after bending, and it is not easy to break. 3 Gold is thrown upwards without bounce. 4 The golden color is golden yellow, soaked with weak acid or weak alkali will not change color; high temperature baking or fire baking does not change color. 5 can be bitten with teeth, gold is easy to bite out of the teeth, and copper is not easy. It gold and gold jewelry are not easy to recognize by the naked eye. Two commonly used simple methods can help you identify gold. 1. Comparison from weight. The proportion of real gold is 19.3, and the proportion of copper is 8.8. The proportion of the two is doubled. . Burning with fire, as the saying goes: real gold is not afraid of burning. After the fire was cooled, the real gold surface was still yellow. If it is black, it is fake gold. three, bending method: You can use your hand to make a curved test on the jewelry, the real gold is soft; the fake or color difference is hard, easy to break and bend.

Observe the color, the higher the purity of the gold, the deeper the color; 2. Burning, using fire to burn gold, if the surface is not changed, it is true; If it is true, the texture of gold is softer.

Yellow, metal, good conductivity. The recognition method is to go to the jewelry shop. It is very simple!
