As we all know, due to the shortage of jade resources in recent years and the overall price increase, the entire market has become a mixed bag, with various imitations and processed inferior products flooding the market. As a result, many methods of identifying the authenticity of jade have emerged, but many of them are not reliable. The following editor will show you the 5 most common ones.

Burning hair

The method is to wrap the hair around the jade, burn it with a lighter and see if it can be burned off. If it breaks, it is fake, and if it doesn't break, it is real. In fact, this method is also wrong. Someone has done this experiment before. They wrapped hair around jade and used a lighter to see if it could be burned off. But the fact is that jade has a strong thermal conductivity and the heat is dissipated, so the hair cannot be burned at all, and is even less likely to be burned off.

If the hair is not tightly attached to the jade, or the burning time is a little longer, it may break. But you should know that many fake jades have good thermal conductivity and they can remain unbroken if you master the method. Therefore, this kind of folk method is also unreliable, and it is very likely to damage the jade, because jade is more afraid of high temperatures.

Listen to the sound

It is rumored that if you tap the jade gently with a hard object, if it makes a crisp sound, it is real, but if it makes a dull sound, it is fake. However, this approach is obviously unreasonable, so let's just take a look at it. Even other types of jade produce crisp sounds.

Scratching glass

Because the hardness of natural jade is between 6.5 and 7, which is higher than the hardness of glass, some people believe that as long as jade is used to scratch glass, if it moves, it is real. But in fact, even fake B-grade and C-grade jade can leave marks on the surface of the glass. Moreover, this cannot prove that it is real jade.

Dripping

Another thing is to drop a little water onto the surface of the jade. If the water drop is round and does not spread out, then it is real jade; if the water flows down quickly, then it is fake. Many fake jadeite have some obvious lines on the surface, which will cause the water droplets to deform or spread. However, these fake jades are now waxed or polished on the surface to cover up these lines, so this method is of no use in identification.

By feel

Some people say that jade has thermal conductivity, so it is true that it feels cool when you touch it. However, the temperature of most natural jades is affected by the external temperature. As long as it is lower than the temperature of the human body, it will feel cool. Put the jade in a high temperature place in summer for a while, then touch it to see whether it is cool or hot. Therefore, this statement has no scientific basis.
