Nowadays, as the price of amber has risen year after year, the price of amber raw materials has risen by 50% to 100%. In recent years, the collection of amber has become a natural investment. For this reason, long ago, some people used various imitations to impersonate amber to make profits, so mastering the method of identifying imitations is very important in business marketing activities. The following small series will summarize how to identify amber fraud.
It is understood that amber fraud from the plastic posing, developed to the current false identification certificate and amber powder to suppress the fake amber and so on. Relevant experts said: "When buying amber and beeswax, certificates and testing instruments can't really guarantee the authenticity of amber, and collectors need to be cautious when it is confirmed that there is no problem."
One of the methods for identifying amber sham: use a salt water method to put amber without any inlays into a pre-dissolved density of 1.2g/cm3 of concentrated brine. If it is really amber, it will slowly float up, while fake amber will not float. of.
Identify the second method of amber falsification: Listen to the sound method. When you put the inlaid amber chain or beads in your hand and gently sway, you will hear a soft, slightly dull sound. The amber sound of plastic or resin will be crisper.
Identify the third method of amber fraud: smell aroma method Amber will have a little or almost no smell when rubbing, or simply can not smell. The amber that rubs to produce a scent is called "Samper". And true amber will emit a loose scent when burned, and plastic or other imitations do not have this scent.
Identify the fourth method of amber falsification: the ether experiment is applied with a little ether on amber, and if there is a feeling that the sticky is dissolved after a few minutes, it is false. It is true that it is still safe for about 20-30 minutes in ether.

Identifying the Amber Fake Method Six: Measuring Hardness When we gently slant the amber back with a needle at a 20-30 degree angle, we 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.
Identify the amber falsification method: 拈 法 法 We put amber on the tip of the finger and found that the weight of true amber is much lighter than some fake amber.

Identifying the amber falsification method: Eye observation This is a trick to identify true and false amber; as long as you have a favorite amber more than three colors and more than three months, you can observe the true and false amber by your eyes.
(1) The texture, color depth, transparency, and refractive index of true amber will change with observation angle and illuminance. This feeling is not found in any other substance. Amber is transparent but very moist, not as unobstructed as glass, crystal, or diamond.
(2) Amber fraud is either very transparent or opaque, and the color is dead and fake. The artificially made amber flower inside the fake amber is very glaring and will feel a cold and chilly light.
