Jade has always been one of the favorite jade of the Chinese. In the market, it is opposed to Hetian jade. However, many people who come into contact with jade think that the water in the jade market is too deep and very unfriendly to consumers. One of them is about jade. Knowledge is too complicated and too trivial. Today we will talk about one.
Consumers who are not familiar with jade knowledge may be unfamiliar with the jealousy of jade knowledge. "蟒" is a term used to describe the weathered shell of jadeite. It refers to the continuous or discontinuous expression of the green jadeite strip in the jadeite on the weathered crust. It is like a python coil, mostly green to dark green.
Generally speaking, there is a basis for the presence or absence of color and color distribution of jadeite. Since the diagenesis and mineralization of jadeite has different eras, the difference in structure and composition is formed, which leads to the difference in hardness. In the process of weathering, the jadeite is different.
Therefore, there are two kinds of jadeite jade: one is the "color 蟒" corresponding to the color change; the other is the "species 对应" corresponding to the structural change.
On the surface of the original jade stone, under the same external conditions, the good place to resist weathering is strong, the structure is more meticulous, and the water head is better, called "species." Generally, the green part has stronger weathering resistance than the colorless part, and the fine-grained dense structure has stronger weathering resistance than the coarse-grained loose structure, so in the weathering process, the green part of the fine-grained structure will protrude to form a "color enamel".
