What are the methods for identifying amber beads?

1.Experiment: Natural amber is so light that it will sink to the bottom when you put it (without any inlays) into the water.

But you don't have to worry. You add the dissolved concentrated brine to it, and when the concentration of salt is greater than 1 to 4 (1 part salt, 4 parts water), the real amber will slowly float, while the fake amber will not float.

2.Sound: Uninlaid amber chains or beads will make a soft and slightly dull sound when gently rubbed in the hand. If the plastic or resin is made of plastic, the sound will be crisper.

3.Incense: Amber has only a faint smell that is barely inaudible when rubbed, or simply not smellable. Amber that produces a fragrance by rubbing it is called "champber". In general, amber only gives off a pine fragrance when burned.

4.Eye observation: This is a trick to distinguish between real and fake amber; The texture, color depth, transparency, refractive index, etc. of real amber will change depending on the viewing angle and illumination.

This feeling is not found in any other substance. Just like we can identify real and fake people, for example, a superb artist can create a vivid wax figure of a person, "confusing the real with the fake" is just talking, and no matter how good the wax figure is, it can't escape our eyes. Amber is transparent but warm, not as transparent as glass, crystal, and diamonds.

Fake amber is either very transparent or opaque, and the color is dead and fake. The artificial production of fake amber inside is very dazzling, and it will feel like a lifeless cold light.

5.Ultraviolet radiation: Put the amber under the money detector, it will fluoresce, light green, green, blue, white, etc. Plastic fake amber, on the other hand, does not change color.

6.Rubbing with static electricity: Rubbing amber on clothing can attract small scraps of paper.

7.Feel: Amber is a neutral gemstone and generally does not overheat or cold. Imitations made of glass will have a colder feeling.

If the landlord wants to buy amber things, I suggest you can go to Bo Bao Zhen ** to have a look.

1. Salt water test method.

Amber without any inlays is placed in 1:4 (salt: water) saturated salt water, amber, light plastic, and resin float, and ordinary plastic, glass, acrylic, and bakelite sink.

In addition, amber with insufficient salt water concentration and a large number of impurities in the body will also sink.

2. Ultraviolet irradiation method.

Put the amber under the money detector and it will have fluorescence, light green, green, blue, white, etc. on it. Amber and golden amber have the most obvious discoloration, blood amber and beeswax discoloration is less obvious, the more transparent it is, the more obvious it is, and the plastic will not change color. Be careful not to test in strong light, otherwise the effect will not be obvious!

3. Ether test method.

Apply a little ether to the amber, if after a few minutes there is a feeling that the stickiness is dissolved, it is fake. It's as if ether is still safe and sound for about 20-30 minutes, but it's true.

4. Weight test method.

If you put the amber on the tip of your finger, you will see that real amber weighs much less than some fake amber. When rubbing the surface of amber with your fingertips, you will find that real amber will have an astringent and sticky feeling, while fake amber will be relatively smooth.

The simplest ways to identify amber are: observation test, relative density measurement, heating or hot needle test, ether test, sound test.

1. Observation test.

Amber is transparent and warm, and amber has different effects when viewed from different directions. Imitation amber is either transparent or opaque, and the color is dull and unnatural. The bubbles inside reconstituted amber are usually flattened to form a long strip, while the bubbles inside natural amber are round.

2. Measure the relative density.

The relative density of amber is very light, and it can be suspended in saturated brine (1:4 brine is saturated in one hand), and other imitations such as plastics are heavier than saturated brine, and will sink when placed in saturated brine.

3. Heating or hot needle test.

If you burn the skin of amber directly with a lighter, it will have a pine fragrance and the amber color will turn black. You can also use a thin needle, burn red and pierce into beeswax or amber, and then pull it out while it is hot. If it emits white smoke and produces a pungent smell of plastic, it is an imitation of plastic.

4. Ether experiment.

Drop a drop of ether in an inconspicuous place that does not affect the appearance of amber for a few minutes, or rub it by hand, the amber will not react at all, while the rubber will be slippery and the pseudoamber made of copal resin will corrode and become sticky.

5. Sound test.

The uninlaid amber beads will make a soft and slightly dull sound when gently rubbed in the hand, and if it is fake amber made of plastic or resin, the sound will be crisper.

1 Historically, New Zealand Cobal resins have been abundant in the market, which should cause us to pay attention to resins, some even if they are antique"Amber"It is still possible that it is a copal resin that has a shorter formation time, rather than real amber;

2 Although the identification of amber by animal or plant inclusions can provide many meaningful references, such as its morphological characteristics can tell us some information about whether it is an imitation or whether it has undergone an artificial pressing process, the significance of the inclusions themselves to the identification of amber is not absolute;

3 Alcohol is indeed a very sensitive, inexpensive, and convenient reagent for distinguishing amber from copal resins. However, it is best to use small droplets in an inconspicuous place to gently rub them, otherwise the surface of the sample will become opaque. Therefore, special care should be taken when using this method to identify finished products;

4 The determination of general physical constants, such as density, refractive index and fluorescence, is not obvious in distinguishing amber from copal imitations; 5 Infrared spectroscopy is a very useful method for accurately distinguishing amber from copal resins.

The real tiger is more than 30w,,, everything else is fake.

Dear, the following steps are required to identify the authenticity of amber pendants:1Observe the colors and bubbles:

True amber is mostly dark yellow, honey brown or brown in color, with bubbles and small scratches on the surface, and the surface looks like a slight cloud. If the color is too uniform, the surface is too smooth, or there are no bubbles or blemishes, it may be made of artificial amber or other materials such as plastic. 2.

Smell: When rubbing real amber, it has a resin-like scent, while artificial amber does not have this scent. 3.

Check the weight: Real amber is lighter in weight and lighter than water, while artificial amber is heavier. 4.

Exposure to ultraviolet light: Real amber emits blue, white, or green light when exposed to ultraviolet light, while artificial amber does not. 5.

Hot Needle Method: Use a match head or cigarette butt from an ashtray against the amber pendant, real amber will not leave soot, only a small pit, while artificial amber will be burned into small black dots. In short, identifying the authenticity of amber pendants requires a variety of methods to make a comprehensive judgment, if you are not a professional, it is best to seek the help of a professional organization or business.
