Some of the popular gold jewelry or commemorative coins on the market are imitation gold products or pseudo -shoddy products. Therefore, pay special attention to identification when buying. There are several commonly used identification methods. 1. The gold jewelry produced by Chinese manufacturers now has a poke and gold content of our factory. 2. The density of weight gold is larger than metal such as silver, copper, lead, and aluminum. Gold with the same volume is 40 % heavier than silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. When the gold supports in his hand, he feels heavy. 3. Looking at the color of gold jewelry, the higher the purity of the gold jewelry, the deeper the color. 4. Listening to the rhyme throwing Jin Jienin on the hard ground. Listen to its sound when landing. The sound of real gold is low, thick, heavy, and no sound. The sound of fake gold is crispy but no dullness. Generally, it is the sound of "Dangdang", and there are surplus sounds. When the real gold landed, there was no fake gold. 5. The hardness of the test hardness is small and the hardness can be bent with your hands. Fake gold feels hard when it is bent with hands. If you scratches on the jewelry with a large needle, the scratches of pure gold products are clearly clear. Low gold -containing jewelry, even if it can draw traces, is more vague. Gold plating jewelry is more vague. The above methods are simple testing methods. In order to accurately identify, the following three methods can be adopted. 1. The fire burning method puts the jewelry in the fire to barbecue, and removes it when the jewelry is red. After cooling, the pure gold jewelry is still new, and the surface of the K gold jewelry shows a gray oxidation layer. The lower the purity, the darker the color. 2. Select a black test goldstone with delicate texture, use gold films with different gold content to draw traces on the test stone, make comparison standards, and then scratch the jewelry you want to test on the same test gold stone, drip the concentrated nitric acid to remove the miscellaneous objects. The traces left on the goldstone are the gold content of the accessories. In contrast to the standard, find out the same color as the trace, which is the accurate amount of the determined jewelry. 3. The nitric acid with a concentration of 70 % is dripped on the jewelry, and the original is true. It is not a real golden jewelry that occurs in chemical reactions.
