The 1. brine method is actually widely used and practical, because the specific gravity of beeswax is about 1.08, which is slightly higher than that of water, while the specific gravity of saturated brine is about 1.25, so beeswax will float on the water surface when put in saturated brine. However, the brine method also has disadvantages. For example, if there are many impurities in beeswax, the proportion will naturally increase, and it may not float on the water. That is to say, some light fake beeswax, such as polystyrene, will float on the water even if the specific gravity is only 1.05. 2. Acupuncture. The principle of acupuncture and moxibustion is to judge the authenticity of beeswax according to the changes and smells of organic gems and other substances after heating. For example, if it is pulled out with a needle, if there is loose fragrance and black smoke, it is really beeswax, but if there is white smoke, brushed and pungent smell, it is a plastic product. The same acupuncture method also has shortcomings. For example, acupuncture can only identify fake beeswax made of plastic materials, while fake beeswax made of other materials cannot be identified. In addition, acupuncture will do some harm to beeswax, which is likely to reduce the integrity of beeswax, thus affecting its value. The principle of knife cutting is similar to acupuncture. True beeswax will be powdery when cut with a knife, fake beeswax made of resin will be massive when cut with a knife, and plastic will be annular. However, knife cutting also has some shortcomings, such as the damage is more serious than acupuncture, and only fake beeswax can be identified, while the second-generation wax pressing knife cutting can not. 4. Organic solution method Because beeswax is an organic gem formed by natural resin petrochemical, it is sometimes difficult to distinguish whether resin products are beeswax or not. At this time, it is necessary to use organic solutions, such as wiping the surface with alcohol. If the surface is sticky and potholes appear, it is probably Coba resin, but beeswax will not react. However, this method can only identify resin fraud. 5. The feel method belongs to the pure empirical appraisal method, because for beginners, you can't feel the difference between organic gemstones and inorganic substances. For example, natural beeswax will have a sense of sipping, soft, moist and sticky, while some fakes with higher hardness than beeswax will generally have a cold feeling. 6. Bubble beeswax will wrap air in it when it is formed. In the process of formation, the liquid components are constantly volatilized, which will form uniform bubbles inside the beeswax, and the bubbles are round. If the bubble is rectangular, it may be fake beeswax or pressed beeswax. 7. Violet light method Because beeswax is formed after the resin is petrochemical in the soil, it will absorb trace elements in the soil, such as phosphorus. Although these tiny phosphorus elements are invisible to the naked eye, they will emit blue, green or purple fluorescence under purple light. With the update of counterfeiting technology, fluorescence can also be faked. What is fluorescent is not necessarily true beeswax, and what is not fluorescent must be fake beeswax. 8. Smelling the fragrance can only identify the authenticity of a small part of beeswax, because many beeswax basically has no smell. For example, beeswax is odorless after optimization, baking, coating and other processes. Even if it smells, it doesn't smell so good. You need to rub or even burn to smell it. Only some beeswax produced in the Baltic Sea can smell it in the natural environment. 9. Listening to the law means rubbing beeswax beads back and forth in your hands. At this time, it will make a soft sound that sounds very comfortable. This voice is dull, not the kind of crisp and impetuous voice. And when listening to the sound, the surface of beeswax will have a feeling of astringency, not satiety. 10. Friction beeswax will generate static electricity after friction. Humans discovered static electricity because of beeswax. In the 6th century BC, it was found that beeswax could adsorb some small and light objects by friction. Since then, static electricity has been discovered. Then, identify the beeswax and rub it against each other. If you can absorb scraps of paper, hair, dust, etc. It may be real beeswax, but there is no static electricity generated by plastic and resin.
