"The seed material has been peeled off, and the gods are hard to break." I believe many friends who are knowledgeable have heard this sentence. The reason for this is that it is difficult for the naked eye to judge the authenticity of the seed material from the jade. It is also because there are many key identification criteria on the skin of the seed material, and the most typical basis is the key point we are going to talk about today. - sweat pores.
In today's era of fake goods, nothing is what humans dare not copy. Even diamonds can be created by artificial means that mimic the natural environment. Then, in the case of today's huge increase in seed materials, under the temptation of huge profits, the skin color of the seed material has become the hardest hit area for fraud...
How to judge the authenticity of the seed through the pores of the sweat? Next, Xiaobian and everyone have a good time to talk about this.
First, what is the sweat pores
The real Hetian jade seed material, no matter how delicate, will have numerous fine pores on its surface, much like the "fine pores" on human skin.
This is the uniqueness that nature has given to Hetian jade. No matter how advanced technology is developed, it cannot be imitated. Hetian jade with a sweaty pore is like breathing, taking the aura of nature and becoming the "national stone" in the world.
1. These small pits are unevenly distributed and there is no law at all.
2. The depth is different, there are deep and shallow, and the bumps are good. The direction and angle are also different.
3. Feeling natural, there is a sense of vicissitudes of years of baptism, no deliberately created mechanical sense.
(This is very similar to the turquoise iron wire. Friends who know turquoise know that the turquoise wire is almost impossible to imitate, because of the natural veins of the green pine wire. Maybe this feeling is difficult to use. Language description, but there will be a difference if you look at it.)
4. Due to the effect of natural oxidation, the place where the pit is touched is not sputum, nor is it a hand, but has a feeling of lubrication.
Second, what is a fake pore
Since it is an important basis for judging the seed material, it must be the key object of the bad business. Let's start with a relatively popular type of counterfeiting - sandblasting.
Sandblasting pores
False pores first: sandblasting
Sand blasting is the use of some synthetic or natural granules to work through a sand blasting machine. It is attached to the surface of the material to form a rugged surface similar to the pores. This is used to mimic the characteristics of the pores of natural seed.
Grinding machine
First, the large pieces of mountain or Russian material are polished, the obvious edges and corners are repaired, and then put into the grinding machine for shaping. The weathered layers and edges of the large mountain or Russian material are worn away to form a cobblestone-like shape. This is the embryonic form of imitation seeds. The surface at this time will be rough. Then finely grind it with a large diamond grinding rod. Finally, sandblasting.
Sandblasting machine
After blasting, take out the fine look, pick the different places, repeat the above steps, continue grinding with the grinding rod, then spray, grind, and then spray... repeated several times until the pores are the same.
Sandblasting and Tianyu seed material identification:
1. The so-called "pores" formed after sand blasting feel as if they are attached to the surface of jade raw materials. They have a feeling of protruding out and cannot be integrated with the material.
2. The surface of the sandblasted pores is like a layer of glue.
3. The surface of the pores formed by sand blasting appears to be too uniform, unlike the pores of the natural material, the distribution is patchy. This feeling is very subtle, and it is more difficult to distinguish if the pseudo-pores are left small.
False pores second: drum material
The pores made by the drum can be said to be much higher than the sandblasting material. The probability of the person who does not understand is greatly improved!
Roller material
The roller material solves the drawback that the pores of the blasting material are too uniform. The fake tool is a bit like the concrete machine on the construction site. It is to pour the mountain material and water into it, and then keep it inside. Twisting and rolling, imitating the formation of the seed material, and in order to speed up the creation of pores, these clever anti-counterfeiters will also add some protruding steel nails in the drum or mix some sharp corners of hard objects for several months. After that, the “natural†seed material was completed so quickly.
Roller equipment
As you can see, the pores of the roller material are very similar to the real pores we saw at the beginning.
Roller pores
But if you look closely, you'll see that it looks a bit stiff, and it's more visible from the side. It looks more like a pinhole, and it doesn't have the smoothness of the pores and pores before the pores.
After all, it is a three-to-four-month-old finished product. It mimics the image again and always carries artificial traces. There is no way to compare the true seed material naturally formed in nature for thousands of years, and it is impossible to imitate the pores of the real seed material. A kind of oily feeling.
Seed pores
Although the pores of sweat are an important basis for judging, the identification is not a technique of “small eating and eating all over the skyâ€. It is only by looking at the pores of sweat to identify the authenticity of the seed material, and sometimes it will take medicine. Therefore, learning more and looking at it, paying attention to the jade that you are sure of, will not go wrong~
