5 thoughts on “Gold is pure and impure, learn how many tricks, and easily identify?”

  1. Exploration
    The surface of the gold jewelry must be bright and clean. There are no marks of obvious processing, no obvious sharp corners, and the feel is smooth. There are no pores, impurities, etc. on the surface. In addition, you should also carefully observe whether there are cracks to avoid buying secondary processing accessories.
    The color
    I often said that gold is "Qiqing, Eight Huang, Jiu Zi, Ten Chicken". It means that if the jewelry reaches 70 % of the gold content color, it should be yellow in the middle. If 80 % of the color should be yellow, if 90 % of the color should be yellow, the gold content reaches 10 %, then it should be 10 %, then it should be 10 % then. It's red.
    The higher the purity of the gold, the deeper the color. rn呈现出深赤黄色成色的黄金,纯度在95%以上;rn呈现出浅赤黄色的黄金,纯度在90~95%;rn呈现出淡黄色的黄金;纯度At 80-85%;
    showing green yellow gold with a purity of 65-70%;
    showing outstanding green gold with white light, the purity is only 50-60%;
    and gold presented by gold presented The slightly yellow and white, the purity is less than 50%.
    The hardness
    In the costume film and television drama, there is often such a plot. Some people use their teeth to bite gold to distinguish the authenticity of gold. The hardness of the pure gold is low, and the tooth print will be left if you bite with your teeth. Therefore, when identifying pure gold, you can try its hardness. If it is too hard, it is impossible to be pure gold. (Except for 3D hard gold)
    Listening to the sound
    The real gold with a color of more than 99 % to throw it on the hard ground. The fake or low golden sound is crispy and unwavering. Generally, the sound of "Dangdang" is made, the sound is loud and crispy, and there is a loud sound, and there is a recovery.
    This burning
    In the burning jewelry, and observe its color change after cooling.
    If it is pure gold, the surface is still golden yellow after burning;
    It if the color is black, it is not pure gold.
    It when it is burned, be careful not to burn the jewelry and deform.
