Chapter 442 Binary Formula

Chen Wenzhe did not inquire into whose hands the flower-mouthed vase fell, but he knew that it probably fell into the hands of Honda.

Thinking of the counterfeit silver coin incident mentioned earlier, Chen Wenzhe knew that there was probably a figure from Honda in it.

Chen Wenzhe didn't want to care about these things, so he just thought about what to do with the two pieces of porcelain in his hands.

This time it can be said that I returned home with a full load. Two pieces of Yuan Dynasty porcelain only cost 100,000 yuan. If Chen Wenzhe had not experienced it personally, he would not believe it.

For something like Yuan Qinghua, it is natural to have a clear transaction and provenance, otherwise problems are likely to arise in the future.

However, even if he gets something, Chen Wenzhe doesn't intend to make it public.

Moreover, he still has to find a way to imitate two more pieces and make them look old when the time comes. He might be able to get the two genuine pieces in his hands through Honda.

He will not easily imitate Yuan blue and white in the future, but blue and white underglaze red will be produced as his flagship product in the future.

Therefore, after returning home, after he had settled the large Yuan blue and white lion rolling ball pattern vase, he hugged the blue and white glaze red jade spring vase and planned to study it carefully.

He is still very curious about how ancient people successfully fired blue and white underglaze red.

As soon as he put his hand on this blue and white glaze red jade vase, Chen Wenzhe saw its magnificent thousand-year experience.

When he was looking at the big can just now, he didn't have time to read it from beginning to end, but selected the key points to look at.

So there are many things that he still hasn't figured out yet.

For example, who made these two things? How were they made? And how did they spread later?

Also, how did it come to Dahai City and exist in a cellar?

After calming down for a while, Chen Wenzhe checked the history of Yu Hu Chun Ping again.

The history of this jade pot and spring vase was earlier than he imagined. It almost reached the Southern Song Dynasty. At that time, the Yuan Dynasty had not yet unified the Central Plains.

It is through this piece of porcelain that Chen Wenzhe saw a different Yuan Dynasty.

Although this dynasty was barbaric, they attached great importance to technology and culture.

Isn’t it very contradictory? Because in the history of this bottle, it has seen the use of powerful technology to conquer the West and the East, which is as magnificent as an epic.

Can you believe that the army of the Yuan Dynasty was able to fire thousands of cannons at once?

He used this technology, which was not taken seriously by the Southern and Northern Song dynasties, to defeat countless of their cities, of course, including those in the West.

Through this piece of porcelain, or wine vessel, and through it accompanying a Yuan and Mongolian general on his expeditions, Chen Wenzhe saw how the rulers of the Yuan Dynasty reprimanded Fang Qiu.

And during the war, how much emphasis was placed on handicrafts.

This is not just talk. When their army attacked the city, although they killed countless people, they were reluctant to kill skilled craftsmen.

Later, the Yuan court even valued some famous folk craftsmen. Not only did they place them to work in government-run workshops, but these official craftsmen were also exempted from all other minor subjects, and their status could also be hereditary.

These practices of the Yuan Dynasty played an important role in promoting the development of the government-run handicraft industry at that time.

Of course, in order to meet their luxury needs, the rulers of the Yuan Dynasty also attached great importance to the porcelain industry in Jingzhen.

As early as the eve of their unification of the country, they had established the "Fuliang Porcelain Bureau" in Jingzhen, which was responsible for supervising the production of porcelain needed by the government.

Not only can the Porcelain Bureau give priority to raw materials that are difficult to obtain from other kilns from the government, but it can also obtain many new types of vessels and new picture design drawings from the "Jiang Zuo Yuan".

Under this situation, Jingzhen Porcelain Industry has developed rapidly.

Perhaps because of the exquisite firing craftsmanship of this blue and white glaze red jade pot spring vase, it was placed in the Fuliang Porcelain Bureau after the war.

Therefore, it can be regarded as witnessing the development of Fuliang, which seems to be over Jingzhen.

These things are actually not important, he is just watching the fun now.

However, through this blue and white glaze red jade vase, he saw more, especially the development process of porcelain.

Before the Yuan Dynasty, the raw material for tire making in Jingzhen had always been porcelain stone.

In the Yuan Dynasty, the "binary formula" method of porcelain stone and kaolin began to be used.

Therefore, the Yuan blue and white binary formula, which is difficult to imitate, appeared and was successfully obtained by Chen Wenzhe.

After adopting this formula, Yuan Dynasty porcelain can effectively increase the firing temperature, reduce the deformation rate of porcelain, enhance the hardness of porcelain, and improve the whiteness and transparency of porcelain. This is an epoch-making advancement in Jingzhen ceramic technology.

Because of such progress, it became possible to bake large Yuan blue and white jars, large plum vases and other large vessels.

Also, before the Yuan Dynasty, the raw material for making glaze was always a single glazed stone.

In the Yuan Dynasty, rubbing ash began to be used to prepare it.

After the glaze-making raw materials were changed, the glaze color of the shadow celadon glaze was darker than that of the Song Dynasty.

In addition, Yuan Dynasty also created an egg white glaze that is white with a hint of bluish white, as translucent as jade, and resembles the color of a duck egg.

Because the "Fuliang Porcelain Bureau" at that time selected this glaze as the "Privy Council", and the "Xingshe Miyuan" fired porcelain for military agencies, this glaze was also called "Privy Council Glaze".

The characteristics of this kind of glaze are: wide firing range, high yield, no flowing or flaking.

In the early days, products with Privy glaze had a slightly higher iron content and the sleeves were white with green flashes;

In the late period, products with Privy glaze had less iron content, the white glaze tended to be pure, the glaze surface was shiny and moist, and the quality was particularly high.

Chen Wenzhe knew about egg white glaze, but he really didn’t know that egg white glaze was invented in the Yuan Dynasty.

It is generally known that Jingzhen has four famous porcelains: blue and white porcelain, exquisite porcelain, pastel porcelain and colored glazed porcelain, but few people know about egg white glazed porcelain.

There are still quite a few egg white glazed porcelains handed down today.

For example, the "Yuan egg white glaze printed Yunlong Taixi Plate" and "Yuan egg white glaze printed folded waist bowl" collected by the Palace Museum.

These items were all unearthed in cellars, especially the egg white glaze printed folded waist bowl. The rim of the bowl is turned outwards, the upper part of the abdominal wall is slightly straight, and the lower part is sharply folded inward.

This unique shape is probably more suitable for the hand holding the bowl when drinking milk while riding a horse.

These things are similar to the jade pot spring bottle in Chen Wenzhe's hands now. They are both wine vessels.

It can be said that the emergence of egg white glaze in the Yuan Dynasty laid the foundation for blue and white and underglaze red.

If the blue and white porcelain before was immature and the underglaze red porcelain was fired occasionally due to kiln changes, then later on, they began to deliberately fire blue and white porcelain and underglaze red porcelain.

Seeing this, Chen Wenzhe has learned a lot, such as the binary formula of the Yuan Dynasty and the egg white glaze.

Among them, Chen Wenzhe actually watched the kiln firing process many times and learned many kiln firing techniques of the Yuan Dynasty.

As long as the kiln-firing process of the Yuan Dynasty occurred near the red jade pot and spring vase under the blue and white glaze, it would have fallen into Chen Wenzhe's eyes.
