Moyu is made of graphite impregnated in the formation process of white jade. Therefore, it has the characteristics of fine structure and grease luster of white jade. According to the degree of immersion in graphite, it can be divided into three types: full ink, ink, and ink. The black color is the most, the best quality is the best, the ink is second, and the ink is again. The color of the jade is black enough and purely optimal.
Black Bi is sometimes called black jade, because its color is darker than the ink and ink in the ink jade, but it is still a kind of jasper.
In the identification of black jade and black bi, the two can be placed under strong light, and it can be found that the ink jade presents a uniformly distributed fine ink dot, and a film-like transparent jade layer can also be seen. In the black and blue, I saw a group of seaweed-like black fog. In addition, from the texture, the ink is soft and tough, while the black and blue is very brittle.
The above is a small series of simple knowledge about how to identify the jade and black bi for friends, I hope to help friends!
