5 thoughts on “How to distinguish between Zhou Dasheng's gold”
Julie
Differential golden and false, the approximate method is as follows:
1, ratio weight. The density of gold is high, and its proportion is much higher than other metals. Generally speaking, the amount of gold products is much heavy for the same volume of metal objects. There is a heavy feeling in the hand. Too light products must be fakes. 2, test hardness. The hardness of gold is very low, the higher the gold texture, the softer. If you use ordinary metal objects to try gently on the gold products, the dentation is generally a real gold, and the pseudo -scratch is the pseudo. 3, listen to the sound. You can throw the gold products on the hard ground, and the sound of "tap" will be made. There is no rhyme, and the gold with a low color will have rhymes, and the sound is sharp. In addition, the jump of real gold is not faked. 4, viewing color. The lower the gold, copper, and iron content in gold, the more silver, the lighter the color, the lighter the color; the copper contains more yellowish yellow and slightly green; the higher the golden color, the higher the color. Therefore, the golden color of gold can generally be observed in accordance with the formulas of "70 % green, 80 % yellow, and 90 % red". 5, dripping nitric acid. The chemical properties of gold are relatively stable and are not easy to oxidize in the air. Gold is in acidic liquid (such as nitric acid, dilute hydrochloric acid, etc.), and its color is unchanged, and as long as the fake gold is touched, it will lose its luster. If it is a gold -plated jewelry, the gold -plated layer is easy to fall off, not only to fall off the part is easy to rust, but even the gold plating surface is easily covered by copper. 6, burning with fire. Real gold is not afraid of fire, using this method to identify the most spiritual gold. After the golden barbecue is still new, the surface of the K golden is burned, but the surface of the smoke gray oxidation is present. The lower the pure color, the darker the surface. Essence
The labels of gold jewelry will be marked with the color, overcome, and quality inspection logos of gold. These consumers need to pay great attention in the usual purchase.
. In addition, each product of Chow Tai Sheng Jewelry Co., Ltd. has a regulatory code supervised by the Chinese Product Quality Electronic Supervision Network. It is the same as the detection number of the National Inspection Center. It is the only "ID card" with its own product, which can be found through the Internet and other methods.

The method of identifying authenticity: 1. Looking at the color, the color of the gold is dark yellow. If it is not pure, then light yellow, the larger the purity, the darker the color. Red yellow color is above 95 %, light red yellow yellow 90-95 %, pale yellow is 80--85 %, cyan yellow 65-70 %, color blue with white light is only 50-60 %, slightly yellow and white and white Less than 50 %. 2, see the mark. Gold is the finished product made by the state in accordance with the production standards. At the same time, there are also tags. This mark will mark the number of gold on the gold, such as 18K, 24K, and so on, but the low color is not given to this mark, so the basic color that can be played is high. Sometimes you need to amplify the mirror to check the mark to distinguish the authenticity. 3, sound. Gold also has the sound of its own metal. Generally, the higher the purity, the sound of throwing on the ground, the sound can be popped. If it is not pure, it will make a dullness, but this experiment needs to be more obvious in a relatively quiet environment. There are certain limitations. 4, real gold is not afraid of fire. That's right, take gold with fire until it becomes red, and then observe what color of the appearance of the gold after cooling. If it is still the original golden yellow, it means that the purity of the gold is relatively pure. Then it shows that there are flaws, which may be fake gold jewelry. 5, hardness. The hardness of gold is actually not large, and it is relatively soft. Therefore, the hardness of pure gold can be opened directly with nails. If you bite with your teeth, there will be a deep seal. If the hardness is relatively large, it may be that other impurities materials are there, such as copper -containing. Using bending can effectively detect hardness. 6, the easiest way, send gold to a laboratory or other places that can be tested for inspection
