The reason why Hetian jade attracts people, in addition to thousands of years of jade culture, is that it has a characteristic that other gemstones do not have, that is, its oiliness. Among them, the oiliness of the seed material is the best, and it is said that the Hetian seed material is the strongest in the natural minerals found so far.
Seed material
So what is the oiliness of the seed material, and where does this oily feeling come from? What issues should we pay attention to? In this article, we will systematically talk about the oily mystery of the seed material.
First, what is the oiliness of the seed material?
Seed material
To put it simply, what we usually call oily actually contains two concepts: jade's visual oiliness and tactile oiliness.
The visual oiliness is actually very well understood, that is, the seed material looks like a grease-like luster, and the gloss is soft, which seems to be a layer of faint shine.
The touch of oil on the touch is the touch of the seed material. It is a slightly slippery feeling of resistance, slippery but not greasy, like oil and oil. It is such a feeling that the players can feel the ability to stop playing with the seeds.
These two points believe that players have experience.
Second, where does the oiliness of the seed material come from?
But the seed material itself is not oily, it is just a piece of jade, why is this oily feeling? What causes the unique oiliness of the seed?
If it is explained from the perspective of science, it may be difficult to understand: the "oiliness" of solid materials is determined by their crystal structure characteristics, grain size, density, reflectivity, transmittance, refractive index and surface finish. The visual response of the reflection effect. These features together form a unique property of the seed: oily.
Crystal structure
Simply speaking, "oily" is related to the size of the seed crystals, the tight arrangement, and the reflected light of the crystal.
As long as one of the above material characteristics changes, the oiliness disappears. For example, the grain size becomes larger, the fineness of the jade is gone, and the oiliness is gone, such as marble. The crystal grains are equiaxed crystal or floc structure or amorphous structure, the plane reflection is enhanced, the glass luster appears, and the oiliness is gone, such as jade, glass and agate. If the transparency is too high (higher than or equal to semi-transparent), it will lose the sense of transparency and layering, and the overall feeling of "snow cream bottle" will be lost. The transparency is too low, and the sense of transparency and layering is lost. The overall feeling of "dead white" is gone, and the oiliness is gone. The density and scattering rate of Russian and Korean materials are slightly worse, resulting in insufficient feeling of fineness and layering (transparency of surface layer); while the density of Qinghai material is not high enough and the transparency is too high, which also leads to lack of delicateness and layering. Adding color and pan-green, the overall effect is lack of oil. It can be seen that a slight change in the material index will affect the perception of jade, which is very subtle.
Seed material
It can also be said that the oiliness of the seed material is closely related to its jade structure, including fineness, enthalpy, density, etc., and it is difficult to have an oily effect when one condition is not achieved. The kind of seed material is just right, it constitutes its unique kind of oily feeling.
If the players are still difficult to understand, it doesn't matter. Playing jade will look good on oil. There is no special need to know how this oiliness comes from. All materials have their uniqueness.
Third, the relationship between polishing and oiliness
polishing
The luster of Hetian jade is related to both jade and polishing. The oiliness and polishing of the seed material is very easy to confuse. Now there are many “seed materials†in the market that are thrown out of the light. The novice can't tell whether it is oil or not, so it is often hit. We must understand the following between the two:
First of all, good polishing can make oily performance better. In the creation of jade carving, the importance of polishing and polishing is no less than that of carving. A good grinding process can better reflect the jade. Generally the seeds are polished to matt. If the density is good enough, the polished jade will have a strong jade texture.
Qinghai
But polishing can't be overwhelming. Nowadays, many merchants use materials that are not very dense, use abrasive powder, or use cowhide sheepskin to "cover", so that the jade-like material can be polished and oily, but such jade can't stand playing. After a few months of disk, the layer of oil on the surface disappeared.
A lot of polishing materials, mountain materials and color are using this kind of "eyelight", many players are deceived because they can't distinguish the "oily" and "oily" feelings. The moistness of the seed material is emitted from the inside out, and there is a feeling of "absorbing light" instead of the light that is thrown out.
Glass light
Finally, polishing has a lot to do with jade. The finer the jade, the better the gloss of the oil that is polished and played. On the contrary, if the jade is thick, it is difficult to polish the oil or shine. Hetian jade, which is not good in jade, sometimes even throws out thief light. The thief light is a kind of floating light, and the gloss flows on the surface, which has a kind of frivolous feeling. In order to avoid this situation, some people choose to use high-speed polishing to throw it into glass light to cover up. In general, Qinghai materials are prone to thief light, and Russian materials are prone to waxy luster.
4. Does the seed material need to be oiled?
When we go to the market, we will find that almost every piece of material is oily. Is this the natural oily performance of the seed? No, this is a layer of oil that merchants deliberately touch and looks more beautiful. This is almost a convention in the market.
Why do sellers like to oil the material? Part of it is because the seed material is placed in the window and the spotlight is baked. The seller is worried that the long-term baking will make the material dehydrated and look dry. It is acceptable to clean the oil. There are also some sellers whose purpose is not so noble, and the seed materials will have some defects, and the oil will cover up these defects in a short time. Therefore, it is best to clean the seeds of the smeared oil when buying materials.
Regarding oiling, should the oil be stored when the seed material is stored? This also needs to take into account the jade of the seed itself. The material is very good. It can be placed directly on the storage. It does not need to rub the oil. For example, the fat of the material is excellent, it is not rubbed or oiled, and it is greasy at any time.
Seed material
What kind of jade needs oil maintenance? Like Panyu, stuffing, stuffing with nuts and some mountain materials, if you don't wear it often, it is ok to apply some oil because these materials are easier to dry.
Therefore, players should not see the polish polished, or get a oily seed is oily, what you see is not necessarily true.
5. Is the oily poor fake seed?
Playing with seed materials, everyone likes oily good, but many players just want to "oil" the material, and when they look at how to not oil, they begin to wonder if it is true. In fact, this is wrong.
Hotan seed can be the strongest of the natural minerals found so far. But not all of the seeds are oily, and some dry seeds are also available.
Seed material
Not all of the seed oils are good in oiliness, nor are they good in oiliness. Is the mountain material not oily? No, there are many good oils in the mountains. Oilyness is only a characteristic of the superior quality of the seed material. It cannot be used as an indicator for judging true and false!
6. Is the patina that is played in the pan as the oiliness of the seed?
Regarding oiliness, many players will ask, isn't the pulping out of the plate the oiliness of the seed? In fact, oily refers to the oiliness of jade itself. Disc play is a feature that changes the surface of the material to form a palate that allows the seed to look more oily. But the nature of the patina and oily is different, such as the stone of tourist attractions, there are more people to touch, there will be a feeling of shine.
Therefore, the oiliness of the seed material does not mean that the sweat is used for a long time, which makes the oily feeling, but the oily, jade and old feeling that the seed material emits from the inside out. The true "oil" nature is the texture of the jade, which can only be met with the eyes. After a long time of playing, this oily has added a new feeling.
But what needs to be said is that Panyu is not like some literary play, but the speed of the jade is not up to speed. Even if it is a high-quality seed, it will take a few years to play the taste.
Seven, how to distinguish the origin from the oil?
Many players don't know how to distinguish between Hotan, Qinghai, and Russian. In fact, oil can also distinguish one or two. Qinghai material gives people a feeling of translucentness, some are very white, but it is the kind of grayish white, and there is no oily nature of the seed material. Russian materials, at present, I have to admit that the fine Russian materials are also very small and the prices are very expensive. However, its characteristics are not as heavy and oily as the seed material, and the Russian material is still dry.
If you go to buy jade, it is best to give up a polished light. Most of the seeds are polished to matt. No one will throw a good piece of seed into a highlight, which is like grinding a skin with a skin color.
The first criterion for seed material is to be oily, moist, and play more and more oil. This is the fun of playing with seeds. Only by cultivating the feeling of fleshy quality, you don't need to look at the structure to look at the structure. It is enough to look at it and see its oiliness and old-fashioned feeling.
Regarding the oiliness of the seed material, it is still necessary for the players to see more and more. When you really understand the oily inside of the seed material, you may actually read the seed material. The warm seed will make you feel a sense of intimacy, and you will feel that it has been integrated into you and become a part of you.
