Common fake jade includes plastic, stained glass, marble, electrochromic fake jade made of jade powder and crystal with salt water, imitation jade containing nitrate, etc. And their identification methods are different. Plastic is lighter than jade, and its hardness is poor, so it is generally easy to identify. Colored glass is also easy to distinguish. As long as you take it under a lamp or in the sun, you will see many bubbles in the glass.
It is difficult to distinguish the fake jade with electric color, that is to say, the inferior jade is easily mistaken for the real jade after being plated with a beautiful emerald appearance. At this time, you need to observe carefully. If there are some small cracks with blue in the green, it is fake jade. Because electroplating will leave cracks, experts call it "spider claws". It is also said that if the electro-colored fake jade is put in hot oil, the electroplating color will fade and return to its original color.
Synthetic jade made of jade powder, crystal and salt water is an imitation dark old pit jade. The identification method is simple, that is, their specific gravity is different. The specific gravity of natural jade is 3.3-3.4, while that of synthetic jade is only 2.8. Weigh by hand, or weigh by balance to distinguish between true and false.
The easiest way:
1. In the sun, there are some cloud-like things in jade, like cotton wool.
2. Jade is very hard, like a diamond, so you can draw a series of marks on the glass.
3, jade is cold, put a hair on the jade, light it with a lighter, and keep it on the jade's head. (To be verified, in fact, when hair burns on glass or porcelain (silicate mixture), heat transfer will occur, and it will not burn until it reaches the ignition point. )
4, water identification method, drop a drop of water on jade, if it is dewy for a long time, it is real jade; The water droplets disappear quickly, which is a fake.
5, tongue licking method, the tip of the tongue licking real jade has a feeling of astringency; Fake jade has no astringency.

Quality appraisal:
1 texture. Natural jadeite is transparent or translucent in texture, and its surface is bright and shiny. If you look closely, you can see the nearly round and slightly transparent "salt particles" and the fibrous substances around them.
② Hardness. Natural jadeite is jadeite, and its Mohs hardness is 7 degrees. It will be carved by a sharp knife without leaving any trace. The hardness of fake jade is low, so a sharp knife can draw it out.
3 Emerald. When natural jadeite is observed under strong light, emeralds with other mineral particles can be seen, which are called Cui Hua or emeralds. Fakes made of glass, plastic and porcelain have no such "emerald" characteristics.
④ Relative density (specific gravity). Natural jadeite has a hard and dense structure, no bubbles, high density, and clear sound when knocking; Fake products have loose structure or bubbles, low density and hoarse knocking sound.
