How to identify the true and false of natural amber
To identify natural amber, in addition to going to the Jewelry Appraisal Center, the other is to look at the hand. Really amber is exquisite, pure color, and fake amber is often lacking in anger. In addition, there are several methods of scientific experiment identification that are popular among the people. The following is a reference for everyone. â– Experiment 1: Salt test This experiment is the main method of identification. Due to the light specific gravity of natural amber, it should float on the water in 1 (salt): 4 (water) brine. It is all calm in the clear water. When the salt is added, the floating product is the real one (except Coba resin). â– Experiment 2: Fire experiment This experiment is not destructive, and its main purpose is to smell. The fire is used in the ordinary lighter, the stay time is 4-5 seconds, Colombian Coba resin and natural amber powder after the ignition of the fire left a clear trace, similar to broken rice. In terms of taste, natural amber has a slight piney scent. Burn the natural amber that has been polished for 4-5 seconds, the surface will become deeper, but it will not have a hole-like skin feel, and the long time will bring damage. â– Experiment 3: Electrostatic experiment It can be seen from the results of the friction test that all materials used except the glass have an electrostatic reaction. This experiment can only distinguish the glass, because the glass usually has no static electricity after rubbing. â– Experiment 4: Washing water test The cheapest manicure that uses nail polish is sold in many places. Colombian coba resin and rosin are obviously volatilized slowly, and they are clearly sticky at the point of hand rubbing and can leave fingerprints. â– Experiment 5: UV irradiation Take the UV counterfeit machine test, polished natural, amber powder pressed, coba resin and rosin will change color, the plastic has a slight change on the top, the synthesis is basically no discoloration. It is not a deep understanding of amber, it will not see the true and false. Summary: The simplest thing to do at home is the above. Basically, other methods of removing fire will cause fish to leak. The salt water experiment can only be un-inlaid objects. Static electricity can only exclude glass. The nail-washing water is useless for plastics and synthetic compacts. Ultraviolet rays are of little use for high imitation and pressing; fire is the most obvious, but it will be physical. It causes damage, and the true natural amber taste cannot be said, and the glazing agent that may exist outside the amber also gives off a pungent taste. The actual combat article can show the results of the same experiment of multiple materials, and the final identification still requires a large amount of experience accumulation and reading of the correct relevant literature.
