The formation of amber takes thousands of years and is therefore extremely precious. The fake amber beeswax that is posing on the market are resin, plastic and glass imitations. Simple and easy identification methods are: 1. Someone has done experiments: put natural amber beeswax bracelets and imitations together in l:4 brine, natural amber can float, and imitations sink into salt water; cut with a knife, plastic imitation Rolling, while natural amber will crack. 2. Tested with hot iron needles, the natural amber beeswax bracelet has a pine scent, the imitation has no loose scent, and some have the spicy taste of plastic. 3. Natural amber has grease luster, imitation products are bright, no grease; natural amber transparency is transparent, translucent or turbid, the latter two are mostly; the imitation is pure transparent, 91% - 94% light transmission. 4. Identification of amber insects: Because the resin is dripping on the insects, the insects in the true amber are small, and there are very few large insects. Many insects can see the true face of the mountain under the magnifying glass. Struggling, some are surrounded by vortex or fog, legs, wings, etc. are not neat, but also have wings or broken legs. The insects in the counterfeit are large and clear. Because they are released after death, the postures are neat, some are still symmetrical, and the legs and wings are well preserved. Much like the natural amber beeswax bracelet, the pressed amber, the regenerated amber, does not change the natural properties of the amber. Pressing amber is to concentrate amber or a small piece of amber, heat it between 200 °C and 250 °C, melt it, and solidify after cooling. There are usually two types of pressed amber beeswax bracelets, one is softened and then pressurized, and there is a deep red bloodshot between small pieces of material; the other is completely softened, this pressed amber has no bloodshot, and it should be under 10 times the magnifying glass. Can see a state similar to the syrup agitation.
