My system is not decent

Chapter 443 Binary Formula
Chen Wenzhe didn't ask who actually owned the vase, but he knew that it probably fell into Honda's hands.

Thinking of the fake silver coin incident mentioned earlier, Chen Wenzhe knew that the little devil Honda might be in it.

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

This time, it can be said that it was a rewarding experience. The two pieces of Yuan Dynasty porcelain only cost [-] yuan. If he hadn't experienced it personally, Chen Wenzhe would not have believed it.

For things like Yuan blue and white, it is natural to clarify the transaction and source, otherwise there may be problems in the future.

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

Moreover, he still needs to find a way to re-replicate the two pieces. When the time comes, they will be worn out, and he may be able to use Honda to whitewash the two genuine pieces in his hands.

He will not easily imitate Yuan blue and white, but blue and white underglaze red, he will produce it as the main product in the future.

So, after returning home, after he settled down the large Yuan blue and white lion rolling ball pattern jar, he held the blue and white glazed red jade pot and spring vase, planning to study hard.

He is still very curious about how the ancients successfully fired blue and white underglaze red.

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

When he checked the big pot just now, he didn't have time to look at it from the beginning to the end, but chose to focus on it.

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

For example, who made these two things?How did you do it?And how did it spread out?
Also, why did it come to Dahai City and still exist in a cellar?
After calming down for a while, Chen Wenzhe checked the history of Yuhu Chunping again.

The history of this jade pot and spring bottle was earlier than he imagined, almost to the Southern Song Dynasty, when the Yuan Dynasty had not yet unified the Central Plains.

That is to say, through this piece of porcelain, Chen Wenzhe saw a different Yuan Dynasty.

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

Is it contradictory?Because in the history of this bottle, it has seen the use of powerful technology to crush the West and the East, which is as magnificent as an epic scene.

Can you believe that the army of the Yuan Dynasty could fire thousands of cannons?
He used this kind of technology that was not valued by the Northern and Southern Song Dynasties to break through their countless cities, of course, including Western cities.

Through this piece of porcelain, or wine vessel, through which he accompanied a Yuan and Mongolian general to fight in all directions, Chen Wenzhe saw how the ruler of the Yuan Dynasty reprimanded Fang Qiu.

And in the course of the war, how much attention was paid to handicrafts.

This is not just talking, as early as when their army sieged cities and plundered land, although they killed countless people, they were reluctant to kill skilled craftsmen.

Later, the Yuan court even attached great importance to some famous folk craftsmen, not only placing them to work in government-run workshops, but also exempting these official craftsmen from all other bad subjects, and their status can also be hereditary.

These practices of the Yuan court played an important role in promoting the development of government-run handicrafts at that time.

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

As early as the eve of their unification of the country, the "Fuliang Porcelain Bureau" had been set up in Jingzhen, which was responsible for supervising the manufacture of porcelain required by the government.

The Porcelain Bureau can not only obtain raw materials that are difficult to obtain from other kilns first from the government, but also can obtain many new vessel types and new screen design drawings from the "Jianzuoyuan".

In this situation, Jingzhen Porcelain Industry has developed rapidly.

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

Therefore, it can be regarded as witnessing the development of Fuliang, and Fuliang seems to be Jingzhen's side.

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

However, through this red jade pot and spring vase in blue and white glaze, he has seen more, especially the development process of porcelain.

Before the Yuan Dynasty, the raw material for making tires in Jingzhen was always a single porcelain stone.

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

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

After adopting this formula, the firing temperature of Yuan Dynasty porcelain can be effectively increased, the deformation rate of porcelain can be reduced, the hardness of porcelain can be enhanced, and the whiteness and transparency of porcelain can be improved. This is an epoch-making progress in Jingzhen ceramic technology.

Because of such progress, it is possible to fire Yuan blue and white pots, large plum vases and other large vessels.

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

In the Yuan Dynasty, it began to be prepared by rubbing ash.

After changing the glaze raw materials, the glaze color of the shadow blue glaze is darker than that of the Song Dynasty.

In addition, Yuanshi also created a kind of egg white glaze with a slight tinge of bluish white in the white, as transparent as jade, and like the color of duck eggs.

Because the "Fuliang Porcelain Bureau" at that time had selected this glaze for the "Privy Council" and "Xinggou Secret Court" to burn porcelain for military agencies, so this glaze was also called "Privy Council Glaze".

The characteristics of this kind of glaze are: wide firing range, high yield, no flow, no cracking.

In the early days, the products with shufu glaze had a slightly higher iron content, and the color of the sleeves was white with flashes of blue;
In the late period, the products with shufu glaze have less iron content, the white glaze tends to be purer, the glaze surface is shiny, and the quality is especially high.

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

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

There are still quite a few egg white glazed porcelains that have been handed down.

For example, the "Yuan Egg White Glaze Printed Yunlong Taixi Plate" and "Yuan Egg White Glaze Printed Folding Shufu Bowl" collected by the Palace Museum.

These objects were all unearthed in the cellar, especially the egg white glaze printed and folded waist Shufu bowl.

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

These things are similar to the jade pot and spring bottle in Chen Wenzhe's hands now, they are all wine vessels.

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

If it is said that the blue and white porcelain was immature before, and the red underglaze porcelain was occasionally fired because of kiln changes, then later, they began to specially fire blue and white and red underglaze 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 a lot of kiln firing techniques in the Yuan Dynasty.

As long as the kiln firing process in the Yuan Dynasty happened near the red jade pot and spring vase in the blue and white glaze, it would fall into Chen Wenzhe's eyes.
