Differential method: First, look at the color, compare a real gold jewelry, the color of light yellow must be fake; second, listen to the sound, the sound of real gold bounces with the fingers, the sound of the finger is dull The worse the color, the worse the metal sound heavier; third, see the hardness, the real gold is very soft to use nails or teeth to press the traces, the worse the color, the harder; Real gold not only has the words "foot gold", "foot red", but also 24K, 18K and other imprints. There are no K marks below 10K; Fifth, the proportion of the real gold is 19.32, the lighter the color, the worse. Of course, the proportion requires experience.
Differential authenticity. In view of the gradual rise in the collection of silver ingot treasures in the market in recent years, the price has also increased, so the main efforts of collecting and investing in silver ingot should be placed on the false falsification. This and silver ingots have appeared in the early years of the Republic of China. The main method is to reduce the color and weight of silver. Of course, the silver ingot that is currently cut -off at this type of cutting -ry materials is not completely regarded as fakes, but only regarded as a "cricket" that reduces quality. However, the fraud of Silver ingot is now different. The main reason for the collector can say that some fake methods have been worse. Roughly speaking, there are mainly the following types of counterfeit methods found in recent years: The first is Li Daotao's stiffness, and metal such as lead tin is impersonally impersonally impersonally impersonated. Because lead tin will appear blue and black on the surface, such fake methods are easier to identify. The second type is strong and strong. When casting fake goods, the copper block is solidified inside the silver ingot, and the appearance of the silver is achieved to achieve the true purpose of falseness. However, due to the different proportion, the volume of this type of fake silver ingot is large and light, and the feel of the heavy feel is obviously different. As long as the silver ingot of the same specification is compared, it can make it original. The third type is to hide the disaster. That is, the lead method is used to dig a small hole at the bottom of the real silver ingot, remove the internal silver, and then pour the lead, and then weld the entrance of the hole. Identification method: As long as you observe it carefully, you can find that the welding marks will be left in the cave at the bottom. The fourth type is the old. The counterfeiters made of old silver -made silver ingot, which made the high price of the old goods. Differential method: This fake veteran ingot cannot show the charm of Yuanbao at that time in the aspects of paste, honeycomb, and casting.

Jin Yuanbao is made of valuable gold or silver. Generally, most of the silver, gold is scarce. In the history of Chinese currency, gold and silver officially referred to as "ingot" and began in the Yuan Dynasty. However, as early as the beginning of the Tang Dynasty in the early Tang Dynasty, the people had its huge and valuable meaning, and read it as "opening ingots". The Yuan Dynasty's Hojin Silver Money was "ingot", which means the Yuan Dynasty.n1. Different from the authenticity of Jin ingot: The density of gold is 19.32 grams / cubic centimeter, which is about double the same volume of silver, lead, and tin. Available formula: The mass (gram) of a certain gold jewelry (gram) is equal to density than the volume (cubic centimeter) of a certain gold jewelry (cubic centimeter). Seeking the density of the gold jewelry measured, the density is about 19.32 grams / cubic centimeter, it is pure gold or relatively pure gold, otherwise it is a non -pure gold or color difference gold (this method has no destructiveness to the jewelry). 2. According to the different gloss and color of gold, you can generally distinguish pure gold, K gold, real gold, fake gold. That is, gold is better with red yellow, and the color is more than 95 %; the positive yellow color is about 80 %; the blue and yellow color is about 70 %; the yellow color is slightly gray and the color is about 50 %. Therefore, there is a formula for "seven greens, eight yellow, nine five red, and yellow leucorrhea ash. For jewelry from Jiu Tibet, there will be a saying that "copper turns green, silver turns black, and gold will never change color". 3. Use the gold -pairing card (the gold medal that has been determined) and the test jewelery on the test gold stone. By comparing the color, the gold jewelry is determined. This method should be carried out under natural light and sunlight, and cannot be carried out under the direct sunlight and incandescent lamps.n1 morenBleak
