China's jade culture has a long history. Hetian jade is of superior quality, smooth and warm, tough and well-known, and is famous in China and abroad. It is the main body of Chinese jade culture. The distinction between Hetian jade is mainly in terms of color, jade, hardness and toughness. 1. The composition is tremolite There are two types of amphibole in the world: tremolite and actinolite. Hetian jade is a tremolite, and the content of tremolite is extremely high, generally above 95%, of which white jade is 99%, white jade is 98%, and jade is 97% (95%~99%). The amphibole content of Hetian jade in Hefei jade is higher. 2, delicate texture and gentle The texture is an inductive representation of the quality of the jade, including shape, degree of moisture, cracks, impurities and so on. Because of its composition and structure, Hetian jade determines its excellent texture. 3, the hardness is relatively large Hardness is one of the important specifications of jade quality. When the hardness is large, the jade has good polishing property, good brightness and long-term preservation. The hardness of Hetian jade was determined to be 6-7. 4, great toughness Toughness is extremely important for jade, and its toughness is large, it is not easy to break, and it is wear-resistant. It has great advantages in the art shape and fineness of jade. Toughness is the grinding hardness, and Hetian jade is a tremolite jade, and its toughness is characteristic. 5, Hetian jade color Hetianyu has its own beauty. People call it "the essence of light, body, such as gelatin, firm and delicate, thick and warm, and it can be used to nourish and ward off, and it is good for people. It is beautiful." The outer skin of Hetian jade stone can be divided into three categories: color skin, sugar skin and stone skin. The color leather is a thin layer of tan or brownish skin of the jade, which is caused by oxidation. The quality of the jade can be seen from the skin color, which is often the best white jade. 6, beautiful sound The sound of Hetian jade after the impact, this is an important property of the ancients to distinguish jade. The jade made by Hetian jade, the sound that was announced when struck, was long and clear, such as the sound of the golden gong, and it was revived, and the residual sound was far and wide. This is what Yude said: "Oh, its sound is clearer and longer, and it ends up being awkward." This feature, other non-Xinshi jade is too late.
