My system is not decent

The opening of porcelain is a kind of knowledge that collectors and connoisseurs must understand.

What kind of porcelain, what dynasty of porcelain, and what kind of openings are all different.

So it's really hard to replicate that.

However, if you don't care about it and just want to open the porcelain, it's easy.

There are two reasons for porcelain chipping, one is artificial chipping, and the other is natural chipping.

Chen Wenzhe learned how to do old work, and he didn't learn the manual opening technology until the old work technology reached the master level.

However, there is no good porcelain, and I don’t want to imitate the five famous kilns in the Northern Song Dynasty. This kind of technology is not used in ordinary times.

After all, the old-fashioned technology was not good enough before, even if some open-piece porcelains were imitated, it would not be of much value.

It's just that it's different now, because he can imitate Ru kiln porcelain.

And if you want to imitate Ru Kiln, the technology of film making is an unavoidable threshold.

Since high imitation is required, it is natural to master manual film opening technology.

As for the artificial opening, one must pay attention to the tires.

The bodies of open-piece porcelain are different, and most of them belong to pulp-bodied porcelain.

The so-called "slurry embryo" is to extract the soaked fine porcelain powder when making embryos, and after clarification, it is melted into mud to make embryos.

Man-made slices, in the process of making these pulp tires, the medicinal materials are prepared.

When it is fired in the kiln, it must be sliced, large slices or small slices, which can be realized by using different ingredients.

The porcelain fired out of the kiln in this way looks like cracks, but the cracks are inside the embryo.

This aspect is the difficulty of imitating Ru kiln, because the real natural opening is definitely not in the embryo.

Natural cracking means that over the years, the glaze layer on the surface of the porcelain has gradually cracked, or it has caviar patterns or ox hair patterns.

Regardless of the shape of the pattern, the card has nothing to do with the embryo, and the pattern will never go deep, but only on the glaze.

Therefore, for all porcelains that open naturally due to age, the glaze always seems to be opened but not opened, and it is faintly visible.

If it is artificially opened, it will suddenly appear on the porcelain body, which is the fundamental difference between the two.

Man-made films began at Ge Kiln in the Song Dynasty, and since then many kilns have imitated them, and Ru Kiln porcelain is certainly no exception.

Therefore, if you want to learn the cutting technology of Ru kiln porcelain, it is better to learn the technology of Ge kiln.

Chen Wenzhe has a brief introduction to Ge kiln and Di kiln.

Although he is more proficient in the younger brother kiln, but he infers the technology of the younger brother kiln from the younger brother kiln, and with some inheritance, he is also specialized in the firing of the younger brother kiln.

Ge Kiln is a kiln factory opened by Zhang Shengyi, the elder brother Zhang Shengyi, a native of Longquan County, Chuzhou in the Song Dynasty.

Ge kiln porcelain has a fine body, strong nature, heavy weight, many broken lines and hidden cracks like fish roe, and there are also large and small broken lines.

The ox hair pattern with yellow caviar pattern on the ancient porcelain belongs to the natural pattern.

The porcelain with natural flakes is said to be found in the Chai kiln porcelain created by Chai Shizong in the Northern Zhou Dynasty.

Porcelain from the Ding Kiln in the Northern Song Dynasty is the most exquisite product among ancient porcelains, and the pieces of which are opened are all willow patterns.

When Chen Wenzhe was studying secret color porcelain, he also studied Chai Kiln, and even extended the technology to Ru Kiln.

These accumulations are the basis for the imitation of Ru kiln porcelain.

As for Jingzhen, there is even more in-depth research on Kaipin porcelain.

After all, the family has a very long history. Even in the Southern Song Dynasty, they had produced powder.

Jingzhen in the Southern Song Dynasty was established, and some films were released, and of course some were not released.

Apart from Jingzhen, in fact, there are quite a few other kilns in China that produce open-piece porcelain.

If a technology cannot be produced by modern people, it is said to be lost.

In fact, if you study it carefully, it may not be lost, but it has just been transformed into other technologies.

For example, the Ru kilns of the Song Dynasty disappeared. Could it be that Kaipian porcelain also disappeared?

No, the Pingyang kiln of that period, also known as Tuding, also had serpentine patterns on its porcelain.

Chang'an Yaoyao Kiln in the Song Dynasty had a thin body and thin glaze with dark flowers. The glaze was very thin and had cracks.

People who don't know it often mistake it for Ding kiln. This kind of Yao kiln porcelain with dark flowers is slightly different from Ding kiln porcelain, and non-appraisal experts will not be able to distinguish it.

Jian kiln porcelain in the Song Dynasty has a white color, which is similar to that of Ding kiln, but there are no open pieces, which is the difference between the two.

In the Qing Dynasty, Lang Kiln produced porcelain in different order.

All the porcelains have openings inside and outside, and there are lamp grass swirling patterns on the bottom feet, and the color is as deep red as coagulated cow's blood, which is a pre-made product.

Another kind of Lulang kiln porcelain, dark green and lovely, covered with fine grains.

In fact, this is a work imitating the younger brother's kiln in the Ming Dynasty. As for the porcelain of the Lang kiln, it has been valued by modern people, but it has also been misunderstood.

The Lang kiln porcelain commonly known by porcelain merchants is actually the gemstone glaze of the Ming Dynasty offering sacrifices to red, and not all of them were made by Lang kiln.

Moreover, some porcelain merchants misunderstood Lang kiln, saying that it was built under the supervision of Lang Shining, a foreigner who enshrined the inner court in the Yongzheng and Qianlong era.

In fact, Castiglione never supervised porcelain making.

The real "Lang" should refer to Lang Tingji, who was the official who supervised the porcelain industry in the Kangxi Dynasty and was the governor of Xijiang at that time.

"Tao Lu", "Tea Yu Ke Hua" and other notebooks are all recorded.

However, the "Lang kiln" mentioned by porcelain merchants actually confused the facts of the Ming and Qing dynasties, and passed on false rumors, which have become a habit.

It is this change in customs and atmosphere that is also evident in porcelain appreciation and price changes.

In the beginning, small pieces of porcelain with large pieces, and large pieces of porcelain with small pieces were all very expensive in the porcelain market.

In modern times, however, in the porcelain connoisseurship circles, the artificial openings of the Ge kiln are not valued, but the openings of the Lang kiln are the most precious.

But in a nutshell, it is more valuable to open a piece of porcelain without feeling the traces with your hands.

These are what Wu San pays more attention to, because they are market-oriented.

However, he didn't know that what he was looking at might not be as important as Ru kiln porcelain.

In the end, we still have to talk about high imitation.

Whether it is Ge Kiln or Ru Kiln, the natural cracks will not go deep into the fetal bone, but only form cracks on the surface of the glaze.

And within the cracks, there are subdivisions, such as Baijunsha.

Baijun is a kind of ice crack, that is, the lines in the crack glaze are dense and the cracks are relatively fine.

This name originated from Ge Kiln in the Song Dynasty, and Jingzhen Kiln imitated Ge Kiln, and it has been used all the time.

Chen Wenzhe's choice was indeed right. Jingzhen has accumulated all kinds of technology in porcelain manufacturing, even if it is a film, it has also done in-depth research.

Through communicating with the two old people, Chen Wenzhe also successfully obtained relatively advanced film development technology.

To put it simply, there are two types of glazes in production.

One is the filling type, which fills the fired glaze cracks with soot, etc., and the lines are black;

Colorants such as copper sulfate can also be filled in the cracks, showing brown-green lines.

The other is the covering type, in which a layer of color glaze is covered on the fired bottom glaze, and then fired again to show cracks and reveal the color of the bottom glaze.
