Density is one of the fundamental factors that determine the quality of Hetian jade, so how does it affect the quality of Hetian jade? Let us take a closer look at the density of Hetian jade. The so-called density refers to the measure of the size of the gap between the internal grains of Hetian jade. Many people may think that the density is the density of jade. In fact, the density of Hetian jade has a great relationship with its density, but it is not equivalent to density. How to see the density of Hetian jade? If it is unloading, it depends on whether the traces drawn by the saw blade are shiny. If it is a finished product, look at the gloss of its surface. Generally, the more intense the gloss of jade, the higher its density and the way it is polished. In addition, how to compare the densities of several jade stones, you can repeatedly wipe them with cloth, the more the gloss becomes stronger, the higher the density, and the good visual effect and jade texture.
