After countless eggshell pottery embryos were made, the wall of one finally met the requirements.
Although it is still 0.5 millimeters, this is the extreme that his current technical level can achieve.
The subsequent process is simple. After the traditional hand-rolled shape, no glaze is applied, and the body is calendered and carved while the body is drying.
After final high-temperature sintering, the kiln is sealed and subjected to coke-smoke carburizing treatment.
The pottery fired in this way is black and translucent, looking like gold, solid and dignified; touching it feels like sweetness, giving people the feeling of "black gold and ink jade".
This kind of adjective is not unfamiliar to Chen Wenzhe.
So if it achieves this effect, he won't worry too much.
After all, the gold bricks he fired before were similar to the eggshell black pottery at this time.
As long as you make a finished product and successfully bake it in the kiln, the rest will be simple.
After the trial burning is over, you can do whatever you want in the future.
The most important things in making eggshell pottery are to practice the clay, draw and sharpen the embryo. After that, everything is the icing on the cake. Even if you don't make it, the finished product is a rare art treasure.
However, Chen Wenzhe now wants to practice his skills, so he must make and use whatever craftsmanship he can and can use.
You must know that carving or even printing on a vessel wall as thin as an eggshell is not a simple matter and requires certain skills.
Chen Wenzhe has a solid foundation and is willing to work hard, so his skill level has improved very quickly.
Knowing that he suddenly felt that whether he was having sex or having sex, it became very easy.
He can already easily master the turntable and produce the effect he wants.
By this time, Chen Wenzhe's embryo drawing and embryo sharpening techniques should have fully broken through to the master level.
Because he has been able to achieve a device embryo with a thickness of 0.2 mm. This is an effect that can only be achieved by combining his embryo drawing technology and embryo sharpening technology.
But now he doesn't know this, he is still making various types of black pottery seriously.
Now he is imitating Shang silk slips, bronze pottery tripods, hollow vases, relief vases, pen washers, pen holders, gourds, incense burners, tobacco pots, hanging plates, etc.
These types of vessels all have one characteristic, that is, they are simple, smooth, simple and elegant.
Of course, it can also be made more complicated. For example, the body can be carved using various expression techniques such as red withering, light withering, and through withering.
You can also add more patterns, and the patterns on this kind of thin-bodied porcelain are mostly based on natural scenery, such as pine, bamboo, plum, chrysanthemum, peony, bird, butterfly, fish, insect, etc.
You can even draw on the characteristics of paper cutting, wood carving, embroidery and other art forms to create more beautiful styles.
For example, the double-layered potbellied incense burner has exquisite hollow relief.
There is also a "dragon and phoenix bottle" with a dragon and phoenix in auspicious patterns engraved on the belly. The entire bottle is a cloud-shaped hollow pattern, with three-dimensional dragons lying opposite each other on both sides, which are exactly the two ears of the bottle. The concept is amazing.
After all, this is not the ancient time. Chen Wenzhe has access to information, not counting the Sui Marquis Pearl. He can also learn a lot of techniques through other channels.
The greatest advantage of modern people is to study ancient times and innovate.
Therefore, some ceramic companies now have more development and innovation than their predecessors in terms of production and firing.
As Chen Wenzhe knows, methods such as wheel-making, molding, printing, grouting, and hand-sculpting are used in production;
In terms of shape, we should pay attention to beauty, simplicity, elegance, various forms and unique characteristics.
The pottery surface has relief, baked colors, and is engraved with ancient calligraphy and painting;
It can be said that it integrates ancient pottery craftsmanship with modern art and craftsmanship;
After making various shapes, the final step is firing.
In this step, the method of high-temperature sealed kiln smoke carburization is generally used, which is not much different from firing gold bricks.
Therefore, Chen Wenzhe also has experience, and the experience is very rich. After all, this is one of the few experiences that he has personally experienced.
In this last step, he can definitely do better.
For example, according to different requirements, he can make the ceramic surface achieve matte gloss, black gloss, or lacquer gloss respectively.
After successfully firing in several kilns, Chen Wenzhe's confidence began to explode.
Once you have qualified eggshell pottery and add a layer of glaze, isn't it just eggshell porcelain?
Compared with eggshell pottery, eggshell porcelain is more beautiful. This is what Chen Wenzhe pursues.
But this time when he was learning to make thin-bodied porcelain, Chen Wenzhe found out strangely that the inherited knowledge contained in the Sui Marquis Pearl actually had the most modern technology.
After further research, Chen Wenzhe discovered that in terms of eggshell porcelain technology, modern technology is even more powerful.
At this point, ancient people really can't compare with modern people.
Chen Wenzhe follows the steps step by step. From ancient times to the present, he has to learn all the techniques related to thin-bodied porcelain.
After a little research, he knew that the thin porcelain technology in the Song Dynasty was the lowest.
The technology at that time can be said to be the foundation, and it ushered in great development during the Ming and Qing Dynasties. However, the real peak of thin-bodied porcelain skills came after the founding of New China.
This is similar to Chinese red porcelain. Modern craftsmanship is much higher than ancient craftsmanship.
Thin-bodied porcelain is also called "bodiless porcelain" and "eggshell porcelain". To be honest, it should have originated in the Ming Dynasty.
Shadow celadon, which appeared from the Northern Song Dynasty to the Ming Dynasty, is moist, delicate and has a sense of transparency. It is an important basis for the production of thin-bodied porcelain.
By the Qing Dynasty, thin-bodied porcelain craftsmanship had developed to a very high level. The products were as thin as cicada wings, and enamel and pastel colors were used to decorate the pictures, forming a unique style.
Among the representative works are the Kangxi pastel December flower cup and the Yongzheng enamel plum blossom bowl.
There are several famous kilns for making thin-bodied porcelain.
For example, the Jingzhen kilns and Dehua white porcelain kilns that Chen Wenzhe had contacted before are still firing thin-bodied porcelain.
Chen Wenzhe also didn't expect that this time he learned how to make eggshell porcelain, he would actually learn the craftsmanship of two famous kilns.
The first is Dehua craftsmanship, of which the representative work is Dehua white porcelain tea set, which is still very popular and sought after by tea drinkers.
The work is made from the rare Dehua pure raw ore kaolin clay.
It went through more than 40 processes including ingredients, drawing, sharpening (repairing), grinding, and firing, more than a hundred times of manual trimming, and two to three firings before it could be completed.
The production of Dehua thin-bodied porcelain takes thinness as the beauty and transparency as the beauty. Therefore, the production requirements are extremely high and extremely difficult, especially the roughness is the most delicate.
The rough blank needs to be trimmed hundreds of times, including rough trimming, fine trimming, and fine trimming, before the rough blank with a thickness of 2 or 3 mm can be trimmed to about 0.5 mm.
Because porcelain is too thin, it is easily cracked and deformed during the production process, making it difficult to make a perfect thin cup.
Only when the knife is cut down, in the state of mindlessness while breathing, can the tire wall be repaired smoothly and thinly.
Although it is difficult to make, after firing, it is as light as a floating cloud, but the final yield is only about 5%.
Among them, Dehua White Porcelain's Cicada Wing series thin-bodied tea ware has a whiteness reaching the highest whiteness of Dehua High White Porcelain of 88.8 degrees, and the thickness of the finished cup is only 0.5mm.
