1. Color discrimination: Gold can be distinguished by color and false through color. Different color gold colors are different. When gold appears red yellow or yellow -red, it is generally the gold content of to 95%of gold. The positive yellow content is generally more than 80%, and the cyan yellow is around 70%. 2, sound identification: gold can be distinguished by sound to identify authenticity. Gold will have a dull low sound when tapping and throwing, and the elasticity is small. N sound is relatively long and accompanied by the sound of the fake gold. 3, hardness identification: gold can be identified and false through hardness. The hardness of the gold is generally low. Use large head needles or nail caps to engrav it. Wrinkles also appear when bending, generally fish scales, if not, it is fake gold.
Pure gold (99.99%of the gold content) texture is softer. The teeth are bite and are easy to bend. The color is golden, pure, soft, heavy, and feels heavy. K gold texture is slightly harder, the teeth bite the mucinoma, the color is yellow in the middle, and the number of K is reduced, the white increases, and the yellow is gradually shallow. K gold's feel is not as heavy as pure gold. The types of confusion with gold are more, some are gold -plated, and some are gold. The following briefly explain: The gold plating is plating a layer of gold on the other metal surface with electroplating method, the color is similar to the real gold, the golden light is bright, and it is difficult to confirm the new time. However, the gold -plated hand feels lighter, the texture is harder, the teeth bite the useless, and it is easy to fade with a long time. Some of the poor plating are plated, the color is either red or white, or flowers. This gold refers to 24K or 22K gold foil on other metal surfaces, such as the K of the gold foil is too low, and its softness is poor. The appearance of Bao Jin is similar to the real gold. The golden light is sparkling and it is not easy to fade, making people true and false. However, if you carefully observe the depression, angle, back, etc. of the jewelry, you can find that the gold foil is uneven and there is a phenomenon of tilting edges. If there is a broken joint, you can see that the cross section of the metal material is yellow. In addition, Baojin's feel is light, the texture is relatively hard, the teeth are bitten, and it is not easy to bend. The copper color is yellow with red, fake, darker luster, soft texture, and light weight. Copper alloy (copper tin alloy), the color is white, the quality is hard and light, and the color loss will make the skin darker.
