What is the feeling of seeing the internal structure of Hetian jade?
Xiaobian knows that everyone understands that in addition to the methods of skin color and moistness, it is also an important factor to watch the structure. It is to look at the internal lines of Hetian jade. This method of observation is called sidelight observation. Today we will talk to you about this related knowledge.
When we look at the internal structure from the side light, we first select a photoscopic observation plane and select the large point as much as possible. For example, when observing the jade card, the front side is usually selected as the observation surface to allow the light to enter from the side angle of forty-five degrees, so that the observation surface is larger. Pay attention to the operation, you need to cover the light of the flashlight by hand to avoid the strong light transmission, and avoid the side light too high, according to the brand observation surface, so that we can clearly see on the observation surface I saw the structure inside Hetian jade.
Hetian jade has sufficient ore-forming conditions and advantages of the optimization process, so that it is more perfect than other amphibole jade, but a few or some of them will have insufficient optimization to occur, so there will be other amphibole jade. Some structural features appear in it. Therefore, Hetian jade will have the unique structural characteristics of the felt-like structure of the cloud-like texture, and it has a certain aesthetic appearance.
The felt-like structure of the cloud-like texture is also the most common internal structure of Hetian jade, which is a unique structure of Hetian jade. Why does Hetian jade have this felt-like structure with cloud-like texture? Because of the structure of Hetian jade, in addition to the particularly slender fiber of tremolite mineral particles, there are many such as fiber cryptocrystalline tremolite crystals, which are other internal structures that are not quite suitable for amphibole.
In many long-term practical experience of experts, it is found that by observing the appearance of cloud-like texture structure, it is easier to judge the fineness of Hetian jade, which is very helpful for beginners. We can set the cloud floc texture into four standards, describing them in terms of the thickness, length, uniformity, and shading of the cloud-like texture. It is better to use the fine, short, uniform and hidden in the silk radish, which is poor in thickness, length, unevenness and obvious difference.
Generally speaking, these four characteristics are very good, the jade quality is naturally the best, the three features are good, and the two features are good. This can give them a more specific grade and is easier to understand. Of course, this kind of structural observation of the amphibole is still difficult for the novice, and must be directed by the old players, and can be learned after a long period of practice.
