My system is not decent

Chapter 1123
The thin teacups of the Cicada Wing series produced by Dehua Kiln, under the light, show the delicate texture like cicada wings, and the tea flows freely in it, giving the viewer a sense of freedom.

Here, the thinness of a piece of porcelain not only reflects the level of porcelain making technology, but also one of the factors that determine the artistic value of porcelain.

On this kind of art treasures, ancient and modern is not a problem, nor is the real value.

What can really reflect the value of a work must be its craftsmanship, followed by history.

You must know that a piece of thin-bodied porcelain needs to go through dozens of processes to complete, and this does not necessarily mean that it can be fired successfully.

If it is a large product, it will take 2-7 months just for painting.

It's just these labor costs that make them extremely valuable, not to mention adding artistic value.

As long as these thin-bodied porcelains are successfully produced, they are extremely precious handicrafts.

They embody the characteristics of our country's traditional arts and crafts in a concentrated way, and are also a model of the combination of calligraphy and painting art and porcelain art.

And with such a top technology, Jing Zhen will naturally not let it go.

Therefore, thin-bodied porcelain is also one of the famous special craft products among Jingzhen traditional porcelain varieties.

The feature is that the porcelain body is as thin as an eggshell, transparent, and made of pure glaze, which is as thin as a cicada's wing, as bright as glass, and as light as a floating cloud.

The thin-bodied porcelain made in Jingzhen is actually similar to that made in Dehua Kiln.

It's just that it is different. Dehua is white porcelain, and on the basis of thin body, it pays more attention to white jade.

But Jingzhen is different here. The eggshell porcelain it makes is very good in all aspects, and it is more well-known.

Jingzhen has a long history of making thin-bodied porcelain. As early as the Northern Song Dynasty, production began here. Its porcelain is "thin and moist".

In the Ming Dynasty, the production technology was further improved, and the "egg curtain cup" made was "only afraid of being blown away by the wind".

In the Qing Dynasty, thin-bodied porcelain reached a higher level, and its porcelain was "purely glazed, with almost no fetal bone".

After the founding of New China, Jingzhen's skill in making thin-bodied porcelain had a new development.

Modern products are thinner, brighter and more beautiful in shape.

Especially in recent years, in order to make this product even better, Art Porcelain Factory, one of the key factories producing thin-bore porcelain, has gathered a group of experienced technicians, who have carried out various work in molding and pastel decoration. Bold innovation has made great progress in the production of thin-bodied porcelain.

In the past, only small products could be produced, but now it is possible to produce large products.

In the past, thin-bodied porcelain was usually painted on one side, but now it has developed into double-sided painting.

In this way, the decorative patterns on the inner and outer layers of the porcelain body look at the light, like colors chasing the moon, looming, covered with light and fog, like paintings within paintings, and stillness within movements.

In the past, there were only more than 40 kinds of varieties produced, but now they have increased to hundreds of kinds.

In the past, it could only be produced in small quantities, but now it can be produced in large quantities.

Product quality, now even better.

Of course, even in Jingzhen now, making thin-bodied porcelain is a special craft, not everyone can make it.

When making it, the raw materials should be selected, and after strict refining, they will be drawn into rough blanks by hand.

Then use various tools to refine the rough blank with a thickness of more than ten millimeters until it is as thin as an eggshell, and then bake it in a kiln.

According to the standards of Jingzhen, only porcelain with a carcass thickness of less than 1mm can be called eggshell porcelain.

The thinness of thin-bodied porcelain products is only between 0.5 mm and 1 mm, and the patterns on the back can be clearly seen in the light.

Therefore, it is light, beautiful, exquisite in workmanship and good in light transmission.

Among them, the classic Ken has said before, there are blue and white, pastel and other types.

Blue and white patterns are depicted on the thin body, which is called blue and white thin body porcelain;

Depicted with pastel patterns, it is called pastel thin-bodied porcelain.

No matter what kind of pottery you make, you must have a suitable embryo, which is a step further than firing eggshell pottery.

It should be known that thin-bodied porcelain has a thin body and low strength, and it is easy to break and deform during the production process.

Its production must go through more than [-] processes from batching, billet drawing, billet trimming, glazing to painting and firing, all of which are done by hand and fired three times.

When making, it is necessary to have highly skilled operation skills and implement strict process regulations.

When batching, in order to prevent the deformation of thin tire products during firing and improve the whiteness and transparency of the glazed surface of the product, it is necessary to increase the content of alumina in the blank and magnesium oxide in the glaze.

With this technology, it is definitely more convenient to process the blanks, especially the blanks and artistic processing are the most delicate.

The rough billet has to go through rough trimming, fine trimming, and intensive repairing hundreds of times before the rough billet with a thickness of two or three millimeters can be trimmed to about 0.5 mm.

The production of thin-bodied porcelain is extremely demanding, especially blank trimming, which is the most difficult and most critical.

In the process of embryo repairing, it all depends on the skilled skills of the workers.

Finally, after more than a hundred repetitions, the rough blanks with a thickness of two or three millimeters can be repaired to be as thin as eggshells.

At the critical moment, one less knife is too thick, and one more knife will ruin the success. If you are not careful, a short breath will lead to the wastage of previous efforts.

This kind of mud has to withstand the test of high-temperature roasting at more than [-] degrees Celsius without cracking or deforming before it can be successful.

Its preciousness and rareness can be imagined, so people call thin-bodied porcelain a magical treasure.

Special attention should be paid here that after the embryo is completed, that is, after the embryo has been trimmed, it is not directly glazed.

Before glazing, the blank is biscuit fired at a temperature of 750-800°C.

When glazing, the inner glaze uses the dripping glaze method, and the outer glaze uses the spray glaze method.

The casket adopts a special pad cake, so that the fine blank can be smoothly loaded into the sagger.

The firing temperature is also completely different from that of ceramics. The firing temperature of eggshell porcelain is 1280°C to 1320°C.

With previous experience in making eggshell pottery, it is relatively simple to make eggshell porcelain now.

The main thing is to change the tire mud, and it needs to be made thinner, because a layer of glaze needs to be applied on the outside.

Compared with eggshell pottery, eggshell porcelain has almost no fetal bone, that is, only the transparent glaze can be seen.

At the beginning of making, we will definitely encounter various problems, so Chen Wenzhe can only make cups at first.

What he made was the famous Twelve Moon Flower Cups in the Qing Dynasty. During the Kangxi, Yongzheng, and Qianlong dynasties, each dynasty made a set of twelve cups, which can also be called the Twelve Flower God Cups.

After he became familiar with the craftsmanship and felt that he could produce high-quality goods, he finally completed a set of Kangxi famille rose porcelain cups with thin bodied flowers in December.

Of course, making a Yongzheng enamel-colored plum-blossom bowl afterwards is what it should be.

After these works were successfully fired, Chen Wenzhe understood why Jingzhen ceramics are famous all over the world for their characteristics of "thin as paper, white as jade, bright as mirror, and sound like chime".

Because of the level of craftsmanship of others, it is really awesome!

It was also at this time that he really knew that the one that truly deserves the term "as thin as paper" should be thin-bodied porcelain.

Thin-bodied porcelain should be as thin as a cicada's wing and as light as silk.
