In order to increase the price of jade, some black-hearted antique dealers often resort to various means to make the jade artifact old. Now the author reveals several methods of counterfeiting to prevent Tibetan friends from being deceived.

Pseudo-lime ancient: There is a type of jade in the ancient jade commonly known as the “bone white”, which is caused by the fire in the jade. Whereas the color of jade is white by the fire, and it is similar to lime, it is commonly called lime soaking. Jade produced by this method, although the color is similar, but there is a fire crack, and really old jade is not cracked.

Yang Yu: The live cattle or live sheep's legs are cut open, and small pieces of jade are filled into the sutures. After a few years, the blood is immersed in the jade, posing as red silk in ancient jade, but this jade does not have ancient jade temperature. Quiet, it looks awkward.

Dog Yu: The dog was killed and the abdomen was cut open. When the dog's blood was still hot and not solidified, the jade was placed in the dog's abdomen and sutured. It was buried underground. After a few years, it was removed and there was spotted blood on the jade. However, compared with the true jade jade, it has the color of new jade and traces of carving.

Mei Yu: Choose jade with loose texture, such as jade or jade skin with heavy stone, cook it with thick ebony water, and repeat it several times. The loose land is soaked with ebony water and shows signs of water immersion. The law "colored to imitate" ancient puddle ", but not as good as natural jade.

Feng Yu: Choose jade with heavier stone, steamed with ebony water and thick gray water, put the jade hot and cold in the snow, so that the jade texture freezes and cracks as fine as the texture of the hair, and finally Also use the "oil lifting method" to impersonate the "bovine hair pattern" jade.

叩 rust: The jade is mixed with iron crushed with hot vinegar and soaked, then buried in the wet underground for more than 10 days, removed and buried under the road for several months. Jade forms a dark red orange peel due to the corrosion of iron chips, and it has dirt spots that are not easily eliminated. However, this fake jade is more floating than red, and the grayish-red spots and red color will fade after a long time.
