Identification and maintenance of amber


First, the identification of amber

1. Experiment: The natural amber texture is very light, and it will sink to the bottom when you put it (without any inlays) into the water. But you don't have to worry about it. You will add dissolved brine to it. When the concentration of the salt is greater than 1 to 4 (1 part salt, 4 parts water), the amber will slowly float, and the fake amber will not float.

2. Sound: Amber chain or beads without inlays in your hands will make a soft, slightly dull sound. If the sound of plastic or resin will be crisper.

3. Fragrance: Amber rough stone that has not been finely polished can be smelled with a special scent after being heated by hand. The aroma of white beeswax is slightly heavier than that of other common amber, so it is called "Sweet". In general, amber that has been finely polished or engraved by hand is difficult to smell by hand rubbing.

4. Eye observation: This is a trick to identify true and false amber; the texture, color depth, transparency, and refractive index of true amber will change with the observation angle and illumination. 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, not as unobstructed as glass, crystal, or diamond. Fake amber is either very transparent or opaque, with a color that is dead and fake. The artificial interior of the fake amber is very glaring, and it will feel a cold and chilly light.

5. Ultraviolet radiation: Put amber under the detector, it will have fluorescence, light green, green, blue, white and so on. Plastic fake amber does not change color.

6. Rubbing with static electricity: Amber can be rubbed on clothes to attract small pieces of paper.

7. Feel: Amber is a neutral gem, and generally it will not be too cold and too hot. The imitation of glass will have a colder feeling.

8. 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)

9. Knife needle selection test: the paper cutting knife will cut into a powder, the resin will fall off in pieces, the plastic will become a roll, 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.)

10. Nail Polishing Potion: Wipe the amber surface repeatedly with a cotton swab and no obvious changes. 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.)

11. 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. 12. Eye bubbles: The bubbles in amber are mostly round, and the bubbles in pressed amber are mostly long and flat.

13. 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, using a variety of test methods Layer separation method.

Note: There is still half amber on the market. True amber is a whole piece of amber rough, but semi-amber is made by melting the processed amber scrap. The difference method can be used to look at the eye, because such amber will have bloodshot, but it will only be some blocky or granular natural impurities.

Second, the maintenance of amber

Amber has a low melting point, is easy to melt, is afraid of heat, and is afraid of exposure. Amber products should be protected from direct sunlight and should not be placed in high temperature places. Amber is easily dehydrated and is too dry to cause cracks. Amber is organic, should not be exposed to organic solvents, such as nail polish, alcohol, gasoline, kerosene, heavy liquid, should not be placed in the cosmetic cabinet, under normal circumstances, do not use heavy liquid to determine its density and use the oil immersion method to measure the refractive index. Amber is brittle and has low hardness. It should not be impacted by external force. It should avoid friction and scratching to prevent scratching and breaking.

Amber is an ancient gemstone jewelry material that has been used as a gemstone for nearly 6,000 years. In many ancient tombs in China, Greece and Egypt, ornaments made of amber have been unearthed. Ancient Roman women have the habit of holding gems in their hands. The reason is that at the temperature of the palm, amber is heated to give off a subtle elegant fragrance. The ancient Romans gave amber a very high value, and an amber-carved figurine was worth more than a strong slave. Amber can also relieve pain and stun. In some places, a bunch of amber is often hung on the chest of the child to excite the evil spirits.
