This method of identifying jade and glass by fire is essentially wrong. It is said that the hair on jade and glass can not be burned by fire. In fact, research shows that both can be burned, but the time of burning is different, and the time on jade is longer.
Jade has been welcomed and sought after by people since ancient times, but because of its popularity, there are still many imitations on the market. When buying a jade, we should first learn the correct identification method to avoid being deceived.
Many people like to use the way of burning their hair for identification. In fact, this method is wrong. Folk rumors say that tying their hair to jade will not easily burn off because of the high thermal conductivity of jade, but if it is a fake jade, it will easily burn off.
However, experiments by relevant experts show that whether it is real jade or glass, it can be burned by tying hair on it and burning it with fire. However, this method is not made up. Although it will be burned out due to its thermal conductivity, the length of time used is still different, and the burning time on jade will be longer.
