Amber, the elf of time, the angel of nature, watching the vicissitudes of thousands of years, condensing the essence of all things for thousands of years, is called "the world's strange stones." Amber is often made into a variety of accessories. Amber like insects are used to make ring stones and chest pendants. They are of high value and the best grades can be classified as gems. In recent years, amber bracelets have become more and more popular among consumers. However, due to too many fake ambers on the market, it has caused great troubles for consumers. Next, China Jewelry Network will teach you how to identify amber bracelets. true and false. 1, salt water test The easiest and most convenient way to identify the true and false amber bracelet is the salt test. Since the density of amber is very small, put the plastic and glass imitation amber into a saturated saline solution (add salt to the water until it can no longer dissolve). Amber will float, and glass and most plastic will sink. When the concentration of the salt is greater than 1 to 4, the true amber will slowly float, and the fake amber will not float. 2, observe the bubble Natural amber mostly presents shapes such as lumps, cakes, kidneys, knobs, elongated drops and other irregular shapes, while regular amber is mostly not real. The real amber gives a feeling of softness, warmth, and luster, and many synthetics give a cold feeling. Amber must undergo some process that makes it imperfect during its formation, often with bubbles, debris, and cracks. If the beads of an amber bracelet are very similar and transparent, or the insects contained in amber are complete, it is suspicious. There are usually beautiful lotus leaf scales in amber, which have different feelings from different angles. False amber is generally not high in transparency, and the scales emit dead light. The observation from different angles is almost the same, lacking the aura of amber. 3, solvent testing Identification of the amber bracelet can be carried out with chemical reagents. Ether and alcohol are very sensitive and cheap and convenient reagents for distinguishing amber from coba resin. Amber is scrubbed with ether and alcohol respectively. Resin is resin and amber. There is no reaction, and ether is the best tool for distinguishing other resins from amber, but it does not have much effect on coba resin. 4, listen to the sound A non-inlaid amber chain or bead placed in your hand will give a soft, slightly dull sound. If the sound of plastic or resin is crisp, this is an important way to identify the true and false amber bracelet. 5, smell the fragrance Amber has only a little bit of smell that is barely smellable when rubbed, or simply can't smell it. The amber that rubs to produce a scent is called "Samper". Generally, amber will only emit a loose scent when it is burned. 6, hardness test When you gently slant the back of the amber with a needle at a 20-30 degree angle, you will feel a slight violent sensation and very fine powder residue. If it is a plastic or other substance with different hardness, it is either stuck or sticky or even stuck in. However, the above experiments are either not done or done less to avoid damage to the amber. 7. Combustion experiment Natural amber with a lower ignition point has no residue after burning, while other artificial amber melts with significant residue. The above is an effective way to identify the true and false amber bracelet, you can choose your own appropriate method, if you feel that the human identification is not enough, you can also send amber to the formal testing agency for testing, where there are expensive equipment and conditions for professional testing. .
