People who like the amber collection know that there are many ways to identify amber, but they don't necessarily know everything. All in all, the following nine methods are commonly used for amber discrimination: First, the sound of the amber collision is reverberant, and Shen Su is not noisy. The synthetic materials such as plastics are sound and ugly. Of course, you should be careful and careful. After comparing them, you can accurately judge the difference between the two. Second, the visual insight into the surface and inside, the true amber texture, color depth, transparency, refractive index, etc. will change with the observation angle and illuminance. This feeling is not found in any other substance. Just as we identify true and false people, such as superb artists can create a vivid figure of the wax, "just to the real thing" is just to talk about, even the best wax can not escape our eyes. Amber is transparent but very moist, unlike glass, crystal and diamonds. Fake amber is either very transparent or opaque, the color is dead, the skin is unnatural, and the surface is cold. In particular, there will be fine bloody filaments, and natural amber products contain impurities that do not contain mechanical distribution or are absolutely dry. Third, the use of salt water ups and downs to identify. Premise, the two are similar in size, without any inlays, the real amber is lighter than the fake material, placed in 1/4 of the salt water, plastic and other synthetic products will sink, while the natural amber will float or even out of the water. Fourth, use a sharp weapon to poke or heat the device to burn the amber, with a new wallpaper blade tip, the amber will see the powder, and the more resin-containing stagnation block open, many plastics will be stagnation or The sheet falls off. The needles and the like are poked at different angles, and the natural amber will be slightly blasted, while other materials, especially plastics (resin materials) may even stay behind the needle tip. Aihua Shang amber is in hot investment... Five, smell the real thing, un-stained amber rough stone, quickly heat by hand, you can smell a light special rosin aroma, white aroma is slightly heavier than other aroma. Sixth, static test, amber on the clothes or hair on the hair, with fine particles shredded paper test, will adsorb above. Seven, feel the experience, amber in the double finger up and down, even with a sense of elasticity and light and slip, the general situation will not be too cold and overheating. Synthetic fake material imitations such as plastics have a cooler feel than the next. Eight, ultraviolet radiation, put amber under the money detector, it will have fluorescence, light green, green, blue, white and so on. Plastic fake amber does not change color. Nine, solubility test: amber after tens of millions of years of tempering, its volatility is weaker than the coba fat that has not yet formed fossils. Short-term contact with ether does not cause any damage. We took two drops of nail-washing water on the specimen to be tested, and felt sticky at the applicator by hand, and could leave fingerprints. However, there is no trace on the amber because the evaporation rate of the ether is faster than the dissolution of the amber in the ether. However, for a long time in alcohol and ether, amber will still partially dissolve because the syrup has 18% to -20% solubility for amber.
