Method for identifying beeswax and amber
Beeswax
1. Brine test method: amber density between 1.05-1.10 in 1:4 (salt: water) saturated brine, amber, lightweight plastics and resins can float, ordinary plastic, glass, acrylic and electricity The wood sinks. (Friendly reminder: this method is limited to bare, the salt water concentration is not heavy enough, the amber with a lot of impurities in the body will sink)
2. Thermal test: the needle is burnt red thorn amber is not obvious, there is a light and loose flavor. Bakelite and plastic give off a spicy odor and stick to the needle. (Friendly reminder: too hot will leave a black surface on the amber surface, affecting the appearance)
3. Needle-cutting test: The cutting knife will cut into a powder, the resin will fall off in pieces, the plastic will be rolled, and the glass will not be cut. Using a hard needle and a horizontal line to puncture amber at a 20-30 degree angle will have a bursting sensation and very fine powder residue. If it is a plastic or other substance with different hardness, it will either stick or be sticky. Get in. (Friendly reminder: This test will bring damage to your jewelry. If you pick out the cut, you can only find a professional to repair it. It is best not to do it or do less to avoid damage to the amber.)
4. Nail Polishing Lotion: Wipe the amber surface repeatedly with a cotton swab. There is no obvious change. There is no change in the plastic and the pressure and the amber, but the resin and the coba are corroded to form a sticky pit because there is no petrochemical. The rosin is put into the syrup and it will melt slowly. (Friendly reminder: Some amber has a layer of glazing material, it will become white spots under the rubbing of the potion, but this layer of white spots can be scraped off with a nail shell to expose the amber surface, and the potion is wiped on it without any change. There will still be 18%-20% melting of amber, and the surface may become foggy for a long time.)
5. Feel: Amber is a neutral organic gemstone. It won't be very hot in summer. It won't be too cold in winter, it is very gentle. With glass or chalcedony, there will be a deep feeling of ice and ice.
6. Eye scales: This is the most important way to identify amber. There are generally beautiful lotus leaf scales in the popcorn amber. It has different feelings from different angles, and the refractive power will not be the same, emitting a spiritual light. The transparency of fake amber is generally not high, and the scales emit dead light. The observation from different angles is almost the same, lacking the aura of amber. The scales and patterns of fake amber are mostly injected, so most of them are the same. The most common one in the market is red scales.
7. Eye bubbles: The bubbles in amber are mostly round, and the bubbles in pressed amber are mostly long and flat.
8. Ultraviolet radiation: Put amber under the detector, it will have fluorescence, light green, green, blue, white and so on. Amber and Jinpo are the most obvious discoloration. The discoloration of blood and beeswax is not obvious. The more transparent, the more obvious the plastic will not change color. (Friendly reminder: Do not test under strong light or the effect is not obvious)
9. Aroma: Amber is only slightly faint or very faint when it is rubbed, but it can't be smelled when it is rubbed, but the amber with the skin will produce a scent when rubbed, and the scent will produce aroma. Amber will only emit a loose scent when burned. (Friendly reminder: there is a fragrance on the stalls, there is a fragrance or just can't buy it)
10. Sound test: Amber beads without inlays are gently swayed in the hands, giving a soft, slightly dull sound, if the sound of plastic or resin is crisper.
11. Friction with static electricity: After amber rubbing on clothes, it can attract small pieces of paper. (Friendly reminder: except for copy paper)
12. Spend money for identification: Get the CMA Jewelry Appraisal Center to measure the refractive index, density, etc.
The best test method: eye, ultraviolet radiation, hand, salt water, other methods more or less even if amber is detected will cause certain damage to amber, the above identification method can not be used alone, should use a variety of test methods Separation of layers, de-authentication!
