Now that he has imitated it this time, Chen Wenzhe might as well imitate a few more.
The first thing I imitated was the Tianzi thin tire cup, then I imitated some other thin tire cups, and finally the Tianzi can!
He had thought about imitating the Tianzi jar before, but now that he had the opportunity and learned a lot of knowledge, it was naturally much easier to imitate it.
The Pearl of Sui Marquis now is really different from before.
Now it can be said that it is responsive to all requests. No matter what knowledge Chen Wenzhe wants to learn, which ancient crafts, recipes, and firing processes he wants to know, he can find it in the information database.
It is also very detailed and even includes some classic models produced at that time.
You must know that these are not just classic wares handed down from generation to generation, but some classic wares produced by various dynasties and kilns at that time.
This is even more rare, and it also broadens Chen Wenzhe's horizons.
Just this point allows Chen Wenzhe to imitate anything he wants to imitate at a high level and with high precision.
If you want to make eggshell cups, you must first make eggshell pottery.
Because the porcelain body needs to be very thin, at least it cannot be much thicker than an eggshell pottery cup, right?
Chen Wenzhe knew a lot about the making of eggshell pottery before. At least he knew that the eggshell pottery cups from four thousand years ago must have been made on a wheel.
He also knew that the wall thickness of ordinary eggshell pottery cups is even and as thin as an eggshell.
The thinnest part is only 0.2~0.3 mm, but the texture is extremely fine and hard.
It is not easy to imitate such a device today.
Moreover, after the eggshell pottery is successfully fired, the surface of the carcass is polished for a long time so that the particles of quartz, mica, sericite and other reflective materials are arranged in one direction, and the reflection of light is changed from diffuse reflection to parallel reflection. Make the watch shine.
You must know that this is pottery, not porcelain.
Because there is no glaze, the surface of the vessel should be very rough.
But eggshell black pottery is not like ordinary pottery. At least the surface has a black luster and is very smooth.
Coupled with the use of holes and fine decorative patterns, its production technology has reached the pinnacle of ancient pottery history.
The high-handled cup is the only vessel shape of eggshell black pottery, and it is also a rather unique group of ancient pottery. It is only found in the early and middle Longshan Culture sites in Qilu.
This may be related to the unique local clay material and pottery making methods, and is also an objective reflection of local people's living customs and aesthetic concepts.
You must know that the firing temperature of pottery must be above 900°C, otherwise the eggshell pottery will not be preserved until this time, because our ancestors in ancient times did not use refractory materials.
In addition, eggshell pottery fired in a high-temperature environment does not deform, and the hollowing process is integrated with calendering.
This further proves that our ancestors, who are more than 4,000 years old, have achieved unparalleled levels of temperature control, carving processing, modeling capabilities, and material craftsmanship.
Therefore, it is a typical representative of the superb skills of prehistoric pottery culture, which so far many artists have found difficult to achieve.
If it turns out that although Chen Wenzhe is very skilled in embryo-making, he has never thought about replicating eggshell porcelain cups. He has never even thought about making eggshell porcelain cups because the technology is too difficult.
But it's different now, because Sui Houzhizhi has released his authority to him, allowing him to easily learn how to make eggshell pottery.
Only now did he know that it takes at least 20 processes to truly make an eggshell black pottery cup.
This seemingly simple pottery is astonishingly complicated and difficult to make.
Using such a complicated process and consuming so much manpower and material resources to produce refined thin pottery is naturally not simple.
This black pottery eggshell cup has a mysterious black metallic luster, with an intuitive visual impact and shock, making people involuntarily feel awe.
Therefore, in ancient times, it was not accessible to everyone. It could only be a ritual vessel used by nobles during sacrifices, funerals, battles, and banquets.
Now Chen Wenzhe is not making pottery, but porcelain. As long as he makes a thin enough body, he can make a qualified work.
Of course, he also needs to use high-quality porcelain clay and a hard enough embryo before it can be glazed and fired.
If you want to go further, you can pile up various techniques on it, such as hollowing out, secret engraving, etc.
However, all these processes require existing thin enough embryos.
Therefore, if you want to make a miraculous thin-shell cup, you must first know how to make an eggshell pottery cup.
The most famous eggshell pottery cup is Qilu black pottery. In the early days, black pottery was made by hand and built with clay strips. The body of the pottery was thick and heavy, and the surface was less shiny.
By the Longshan Culture period, the wheel system had been widely adopted.
Coupled with the improvement of pottery kilns and the mastery of kiln sealing technology, the craftsmanship has been greatly improved.
The production of black pottery during the Longshan Culture period generally used fast wheels.
Its shape is well-proportioned, regular, fine in workmanship, extremely high in heat, and hard in texture.
Research shows that our ancestors had mastered the advanced kiln carburizing technology as early as 4,600 years ago.
This allows the thick smoke that permeates the kiln to infiltrate the carbon particles in the smoke into the body through "smoke carburization", making it black.
The production process of Longshan Culture eggshell black pottery is very complicated, and all the clay used is fine mud that has been washed repeatedly.
Therefore, there are no impurities in the pottery body, and its texture is fine and has almost no water permeability.
After the clay is made, it is fired with charcoal and carved out of the kiln, a total of more than a dozen processes, before it is finally fired into a piece of black pottery.
Especially for eggshell pottery cups, the wall thickness of the cup is even, with the thinnest part only being 0.2-0.3 mm.
Therefore, even today with the development of modern technology, it is quite difficult for researchers to imitate the firing of such thin and light pottery.
The "smoke carburizing method" of black pottery has also been recorded in the history of world arts and crafts.
Chen Wenzhe now has master-level clay training techniques, so it is not difficult at all to learn Longshan eggshell pottery clay training techniques.
As for the raw materials, we must use the tire clay from some major modern porcelain manufacturers.
For works like eggshell pottery, in any era, as long as someone knows about it, has seen it, or just understood it, they will definitely find a way to imitate it.
Modern people are no exception, so it is not difficult for Chen Wenzhe to buy some on-site materials.
Of course, even if there are suitable porcelain-making materials, the production process of Longshan black pottery must be learned from.
After all, Longshan black pottery is what he needs too.
Since you want to make eggshell black pottery, you must bake a batch of eggshell goblets.
If you want to bake eggshell pottery, not to mention other things, it is just the making of a clay body, so you definitely need to study it carefully.
Chen Wenzhe's hometown is Qilu. It turns out that although he has never learned how to make eggshell pottery, he knows a lot about the modern production process of eggshell pottery.
Now across the land of Qilu, three major series of imitation, copying and innovation have been formed.
They have formed more than 300 varieties of black pottery in six categories: antique, transplant, copy, craft, ornamental, and practical.
