I often listen to the old players, how is the powder of Hetian jade material, and what is the fat powder in Hetian jade seed material? We say that the fat powder is one of the hard indicators of Hetian jade material, and it is also a source of obviousness, that is to say, the material The heavier the fat, the better and the better.
Hetian Yuzhong's fat powder, which can be said to be Hetian jade oiliness, twist, fat, gelatinity, can also be used to describe the fineness, density, moistness and even the feel of the material, these are called - fat powder.
Powder fat is one of the hard indexes of Hetian jade
People who play white jade like to say how oily. But sometimes they don't necessarily say the same thing. Oily includes two aspects, one is the visual oily luster, and the other is the feeling of oily feel on the hand.
The visual oily luster, in general, is highly oily and soft. It is related to the tightness of the white jade (ie the size of the gap) and the way it is polished.
Most of the seeds are polished to a luster, and some other materials will have a glass luster. Although it is related to the grinding method, it is also related to the silica content inside. For sanding, the higher the grinding speed, the finer the sanding will be, the stronger the gloss will be. Therefore, some polishing masters like to use cowhide after the oil stone is polished. This will look oily, but it may not be good, because the hand is out. The oiliness is the best, so some things that are polished to matt and start to look unoily are better, but the premise is good enough.
If it is a raw material that has not been polished, you can see the cut marks to know how shiny the finished product will be. The traces of the saw blade will have a trace of strong oily luster, and the finished oily luster will be better. The fineness of the particles, the fineness and uniformity of the white jade have a great influence on the jade, and it is also one of the important basis for judging the different materials. Although the structure of the seed material is loose and dense, the size of the particles is generally smaller than that of the Russian and Qinghai materials. Russian and Qinghai materials generally have larger particles, so they are not easy to be polished, and they are prone to spotting spots.
Through the special grinding, the surface of Russian and Qinghai materials is as delicate as the seed material, which will be fooled by many people, including some experienced sellers.
This kind of delicate and oily by polishing, after a few months of playing, will gradually fade away. Therefore, many people say that the material of Qinghai is more and more sturdy, in fact, that layer of polishing layer has subsided, otherwise the jade has a more and more dry.
Powder fat is a representative of high density
Fineness, that is, fineness, is one of the important quality indicators of white jade. It is also one of the main reasons for the difference in appearance and feel of finished products. It has two aspects: one is the size and uniformity of white jade crystal particles, and the other is also the structure. Fineness, that is, the fineness and uniformity of short cloud flocs.
Generally, the finer the density of Hetian jade, the more positive the chromatogram it appears, and the finer seed of white jade except for the white fat jade is generally yellower and more dense. The more white, the stronger the stone. The reason why the chicken bones are popular nowadays is that the white and beautiful skin color attracts many consumers. The disadvantage is that there is no powder fat. Therefore, both white and play secrets are determined by their own hobbies.
Powder fat is a sensory indicator
Hetian jade is unique in the sense of greasy feeling. The various traces of non-ferrous metals in the Kashi River in Hetian have raised the characteristics of Hetian jade. They can't be replaced. They are always touching and happy, and they are happy. I always want to use my hands to touch the disk to play. Hetian jade, which has been passed down for thousands of years, must have its historical and cultural significance. It must have its unique and inalienable nature. Its spirituality is widely accepted and passed down by the Chinese.
For Hetian jade seed material, it is a minority that does not see the structure, and Qinghai is expected to be invisible to the light. The Qinghai material is not a fine structure of the cloud floc, but the cloud floc structure is incompletely developed. It will be found that more is a fine dot structure. The Russian material generally has a large cloud structure and is entangled with plaque structure, but there are also a small amount of fine structure that does not even see the structure. The high-light white light does not see the structure of Qinghai old materials and high-quality Russian materials.
Powder fat is an indicator of hand feeling
A good material must also have the oiliness on the hand. The oilyness on the hand feels a slightly slippery feeling of resistance. It is like holding a piece of oil in the hand and pushing it with your hand. There is a feeling that the oil has to be opened. Seed jade has a unique advantage in terms of hand touch. This is the appreciation of Hetian jade. It is necessary to get started to know why it is good or bad.
For the seed material, the finer the finer the cloud, the better the whiteness of the seed material will be slightly larger, the whiteness is high, the structure is dense and the price is very expensive. Fineness, that is, fineness, is one of the important quality indicators of white jade. It is also one of the main reasons for the difference in appearance and feel of finished products. It has two aspects: one is the size and uniformity of white jade crystal particles, and the other is also the structure. Fineness, that is, the fineness and uniformity of short cloud flocs.
Powder fat is a significant source
The white jade is oily. The reason why Baiyu is attractive is that apart from thousands of years of jade culture, one of the main reasons is that white jade has a characteristic that other jade and jade do not have, that is, its oily nature, warm white jade will make people feel a kind Being close, you will feel that it has been integrated into you and become a part of you.
What kind of oily performance is good?
糯 就是 is a kind of honest feeling, for example, take a closer look at the feeling of good rice cooked, thick and oily and homogeneous, people generally only know this visual ambiguity, in fact and visual The singularity is that it has a kind of stickiness. When you are carving things, you will find a sticky feeling between the sturdy material and the drill bit. The sturdy and fine-grained intertwined dense materials will appear to be more sturdy.
