For the identification of jade, some people say that the light of the money detector can be used to test the true and false of the jade, and it can be judged whether the jade is A or B, whether it is filled and dyed. Then the counterfeit machine can really identify the true and false of jade? Next, the small series of China Jewelry Merchants Network will tell you about the authenticity of the money detector. Can the light of the money detector be used to identify the true or false jade? Everyone should know that jade is divided into several categories, including jade A goods, B goods, C goods, etc. Among them, only jade A goods are natural jade, others are more or less artificially processed, from the price point of view, A Jadeite, even small is very expensive, at least a few thousand or tens of thousands of starts; and if it is B+C goods, it may cost tens of dollars. So using a money detector to identify the texture of jade, does it work? Someone once did an experiment, which is to put the natural jade, that is, the A goods, into the fluorescent lamp. As a result, the A goods are only reflected under the fluorescent light, and they do not emit light. After that, we put a B-car jade into the fluorescent lamp. Sure enough, it emitted silver-white fluorescence, and then put a B+C cargo into it, and the result was the same. So why is this happening? The answer is actually very simple. Fluorescent lamps or counterfeit lamps emit ultraviolet light. Under ultraviolet light, some substances emit fluorescence, but natural jadeite is pure stone and does not emit light under ultraviolet light. Detector identification Many people may not understand that the treatment of jade usually adds an epoxy resin, which is a synthetic organic substance that fluoresces under fluorescent light. According to the amount of epoxy resin added, its fluorescence reaction will also be strong and weak, and the more light is added, the stronger the light. So, is it that the "treated jade" will shine under fluorescent lights? In order to find the answer, we tested several samples and found that the B-car jade and the C-car jade will not shine. So why is this? Now that science and technology are advancing, the means of falsification is also improving. Some falsifiers will add a substance that inhibits this fluorescent reaction in the jade. Also, if the body color is dark green, it may also cover up part of the fluorescence, but the most important thing is the presence of a fluorescent inhibitor. In addition, if the fake jade is only a C product that has been dyed without adding organic glue, there is no such fluorescence reaction under fluorescent irradiation. Therefore, everyone noticed that using the light of the money detector to identify the true and false jade is not reliable. Cardigan, a style of top. The front part is completely separated.
