The so-called reading jade is the understanding of jade. Different people have different methods of reading jade. They also have different understandings of different jade people of white jade.
For the material-cutting master, the hardness of the material is high, and it takes a long time to cut. The material has a sticky force on the saw blade, and the trimming is not neat, and the jade is good.
For the engraver, when carving, the lines of the carvings are not easy to collapse and the jade is good.
For the polishing master, it is relatively smooth, not easy to streak, and it is easier to produce gloss and oiliness.
For ordinary players, oily and invisible structures will say that jade is good.
For the veteran players, jade looks old-fashioned, jade texture and a natural noble air is a good performance of jade.
How should we measure the quality of jade? The market often sees some novices get the jade one to compare the whiteness, and then take a side light to see the structure, so can you correctly evaluate the jade?
The result is that the good Qinghai and Russian materials are bought as the top seed, because those materials are white and do not see the structure, but are those materials better than the seed?
But the master chef will tell you: No, the hardness of those materials is still lower than the good seed.
The engraver will also say: No, the lines that are particularly thinner are more likely to smash than the seeds.
The polishing master said to you: No, those Russian materials are difficult to polish and smooth, and they are more likely to be streaked. It is necessary to rely on more complicated grinding methods to achieve similar luster and visual effects.
Senior veteran players will say to you: No, the oiliness, feel, jade texture and interior light of those materials are not comparable to the seed material. It will become dry after a long time.
So what is the essence of jade? And how do they affect the performance of all aspects of jade?
In fact, the essence of jade is determined by the following factors: fineness, interweaving degree, density, purity, all forms of seed jade (fineness, oiliness, sturdiness, luster, jade texture, oldness, inner Light, etc.) are derived from these four points. These four points are the foundation of the quality of white jade. If you understand these four points, you can explain the differences.
First, the degree of detail
Many people tend to mistake the size of the seed jade structure as a delicate degree. In fact, this is not the case. The fineness is the size of the particles in the white jade. The difference between the seed material and the mountain material, as well as the Russian material and the Qinghai material, is mainly in the fineness. The granules of the material are generally much smaller than various kinds of mountain materials, which is why the seed material has better oiliness and feel than the Russian material. Why use sheep fat to describe the top white jade seed is because the sheep fat is very delicate, there is a feeling that it can melt it. Only the fineness of the tray will have this feeling. I used to sell it. To the little Buddha of love, it can be said that it is a model in terms of delicateness. After she got this thing, she said to me that this is the best material she has ever seen, and there is a feeling of melting soon. In addition, if the density is good enough, the polished jade will have a strong jade texture. The so-called jade texture is a soft and strong luster, but also contains a strong internal light. Jade pieces with strong jade texture are born with a noble atmosphere.
Russian and Qinghai materials generally have larger particles, which means that the fineness is poor. The performance is not easy to sand and smooth, and the hand feels more oysters. This is because the particles of the crystal will be harder than the surrounding, so the larger the particle, the difference. The more obvious, the Qinghai and Russian materials often produce bright spots or mottled feelings. Now the grinding technology can still polish these materials to look very fine and oily, but it can not change the nature of the particles, so after comparison After a long time of playing, it will become raw, why? For example, you can help everyone understand that you use cement to cast a stone slab, the cement particles are very fine, so the surface is smooth, the more slick and bright on the top, but if you add a lot of stones or yellow sand in the cement, then It's not easy to grind flat, but it can be smoothed with the machine, but after a long time, the hardness of the cement is low, and the yellow sand and the stone are raised due to the high hardness, so the time is changed. Hairy. This is the reason why the Qinghai material will become raw for a long time. In fact, they are like this, artificially polished will still change back to its original appearance.
It is said that the fineness is actually bottomless. Just like whiteness, there are finer details in the fine, so many jade friends will ask me if the fineness of this material is top-level. In fact, this is wrong, delicate. Degrees cannot be expressed at the top level.
Second, the degree of interlacing
The interweaving degree of the seed material is what we usually call the structure. It is used to measure the intertwining and interweaving of the crystals in the white jade. The interweaving degree is the basis for the toughness of the jade material. In short, the more fully interwoven the jade, the better the toughness.
What kind of structure (interlacing degree) is the best, is it that the side light does not see the structure? This is not true. In fact, many Qinghai materials are basically invisible to the sidelights. This shows that the Qinghai material is incompletely intertwined, so Qinghai has insufficient toughness, is soft to cut, and is brittle at the same time, so in general, Qinghai is three. The worst quality in the producing area, the Russian material is much better than the Qinghai material. At least the cloud floc structure can be seen. Although the general structure is large, the interweaving is not enough. The structure (interlacing) of the material is directional, so Different directions are cut in the direction of the material, and it is easy to break up. Some directions are good.
In general, white jade needs to be interwoven. The finer the toughness, the better the toughness. For the jade material, it is not lighted and the structure is not visible. The side light can see a very fine and uniform structure. Material.
Third, the density
It is an indicator of the grain gap size of the seed material. The density is not equal to the density. Although it has a great relationship with the density, and the density is not what we usually call the structure, I know that many people regard the structure as the density. This is not right, then how to see the density, if it is the material to see the density is to see if the trace of the saw blade is not shiny, then how does the finished product look density? The density of the finished product is to look at the luster. The gloss is strong and the density is high, but it is related to the grinding method. Therefore, if you want to compare the density of several jade, you can use the following method: respectively, put these jade on the cloth. Rubbing hard, the more the gloss becomes stronger, the higher the density. Of course, this is only for newcomers. For experienced people, you can feel the density of a piece of jade at a glance.
With the same grinding method, the gloss of the jade material with high density will be brighter, and the visual effect of the finished product will be better, and the jade texture will tend to be stronger.
Fourth, purity:
It is the purity of jade material, which is the index of how much cotton, stiff flowers, jade flowers, ochre, water lines, lines, etc., are these things not necessarily good jade? In fact, this is not the case. Purity is only an indicator. It still needs to be combined with other indicators. At the same time, it is also looking at the position, to what extent, for example, a beautiful woman has a small flaw, is it not a beauty? of course not. So long on the face, not necessarily, how big it is to see if it affects the beauty, maybe it’s a beautiful woman, it adds a bit of beauty, but if there are dozens of black spots or cockroaches on the face, Even if it is small, it is also a numbness. If it is bigger, it will be ugly. In fact, the same is true of the white jade. It depends on the specific level, so everyone should understand.
With these four elements of white jade, you can understand the various manifestations of jade at the top of this article:
——High hardness when cutting material---high density
——There is a stickiness to the saw blade when the material is opened---high degree of interweaving
——The cutting edge is neat and does not produce hair when the material is opened---high degree of interweaving
——It is not easy to collapse when engraving---high degree of interweaving
——It is easier to grind and smooth when grinding---fineness is good
——It is easier to make gloss when grinding---high density
- fine structure - good intertwined
——Oil----fineness and density
——Sexuality---fineness and interweaving
——Inner light intensity---fineness degree of interweaving and density
——The texture of jade is strong---the delicateness, the density is very good, and the interweaving degree is better.
——Old sensibility---Comprehensive degree, density, interweaving degree, purity is good and a comprehensive feeling.
Therefore, oily, internal light, jade, and old-fashioned are the most important for jade quality (especially the last two), because they are the comprehensive performance of several jade elements, which is far more than the side light. Look at the structure is important, some poor materials to see the side light is still very good, some very good material to see the side light can still see the fine and uniform structure, of course, you can see the obvious structure without lighting, certainly not It will be a good thing.
If you learn to grasp and choose white jade from the inner light, the jade texture and the old feeling, then you will definitely choose the jade good jade material, and you will not be on the fake seed material.
