My system is not decent

Chapter 589
Jihong porcelain, that is, ruby ​​red porcelain, must be high-temperature colored porcelain.

This kind of porcelain is fired by adding a newly discovered natural "purple porcelain ore" in the high territory.

Because this kind of ore contains high metal copper and manganese elements, in the process of burning paper, after undergoing 1380°C reduction and oxidization flame calcination, it enters the silicate crystal and forms a gem-like structure.

Because of its crystal-clear and jade-like color, which is pink in color, similar to the color of ruby, this kind of porcelain is called "ruby red porcelain".

Therefore, firing this kind of ruby ​​red is really simple, but if it is not simple, it is really not simple.

Especially when combining blue and white materials to fire blue and white underglaze red, it is even more difficult.

Even if ruby ​​red porcelain is fired alone, it is difficult to successfully fire it if only purple porcelain ore is added.

In fact, the most important thing in it is the formula and firing process of copper red glaze.

If you can't even master these two techniques well, then it's impossible to make ruby ​​red porcelain with whatever ore you add.

Thinking of this, Chen Wenzhe simply used the copper red glaze he had just prepared to make a few small ruby ​​red bowls.

If it is not a triangular cup, it is not suitable to be made into pink, and he has an urge to dye the triangular cup red.

Several small cups and small bowls were all glazed with copper red glaze. Chen Wenzhe opened a small electric kiln again to fire them.

This is the advantage of having a factory. There are people who help Chen Wenzhe do many things.

Of course, modern technology has also greatly liberated manpower.

For example, firing kilns, these small electric kilns have a small window that allows them to see the internal firing situation, and it is more convenient to control the temperature.

Otherwise, Chen Xingchen was the only one guarding the electric kiln, which would be hard to see.

After closing the kiln, Chen Wenzhe personally watched the temperature changes in the kiln, and began to adjust the temperature continuously.

He didn't avoid Chen Xingchen for these things, and Chen Xingchen watched carefully and recorded some data tacitly.

It turned out that in Professor Tao's studio, Chen Wenzhe had taught Chen Xingchen some skills and experience when he was firing the kiln at night, not to mention that now that Chen Xingchen had defected to him, Chen Wenzhe had no reason to cherish himself.

"The most important thing is that when the temperature rises in the initial stage, the copper ions will start to volatilize at [-] degrees. If all of the volatilization is gone, the firing will definitely fail, so you must be very careful when the temperature is raised in the initial stage."

Seeing the temperature rising step by step, Chen Wenzhe had no choice but to remind Chen Xingchen.

Chen Xingchen obviously also knows about copper red glaze, after all, he is also Professor Tao's favorite student.

Chen Wenzhe still admires Professor Tao's vision of people.

Therefore, in principle, Chen Xingchen is his direct senior brother, otherwise, Chen Wenzhe would not trust him so much.

"Understood, don't worry, I still have the skills I should have, but Professor Tao's major is not in this area!"

Chen Wenzhe nodded. Professor Tao's majors are five colors, pastel colors, blue and white colors, and fighting colors.

As for the type of porcelain, he must be best at the revolving vase, but if it is possible to make a revolving vase, is it difficult to make other porcelain?

The main reason is that Professor Tao is not involved in the use of copper red glaze, so Chen Xingchen can't learn related knowledge if he follows him.

In fact, there are really many difficulties and difficulties in firing copper red glaze.

Generally, the red glaze is a red glaze porcelain with high temperature copper as the colorant.

Although red-glazed porcelain has been successfully fired since the Yuan Dynasty, the glaze color of the porcelain in the initial stage is mostly dark.

It was not until the Yongle and Xuande periods in the early Ming Dynasty that Jingzhen kiln produced pure and bright red glaze, which was called bright red by the predecessors.

It uses copper as the coloring agent and is fired at high temperature in a reducing atmosphere.

Because it is particularly sensitive to temperature and atmosphere requirements, if you are a little careless, you can't get pure red.

Therefore, high-temperature copper red glaze is the most difficult type of colored glaze to fire, and the finished product has always been cherished by people.

This kind of red glaze ware has a thick glaze and bright colors.

Because it was used at the altar for worshiping the sun at that time, it was also called sacrificial red, and it also had different names such as Jihong and ruby ​​red.

The Xuande Dynasty was the most glorious period for the production of red glaze wares in the Ming Dynasty.

During the Xuande period, red glaze wares not only increased significantly in quantity, but also outperformed Yongle bright red glaze wares.

Xuande red glaze is rich in color, and often at the corners and corners of the utensils, the fetal bones are hidden and white veins appear, which adds to the visual changes of the viewer and is intriguing.

The red-glazed porcelain of later generations did not have the craftsmanship of Yongxuan red-glazed porcelain. This craft was lost and was not restored until Kangxi.

However, after the restoration of the Kangxi period, can it be passed down to modern times?Can modern people make it?
Not necessarily, at least apart from Jingzhen, there are not many other places that can burn sacrificial red.

If it weren't for these reasons, Chen Wenzhe really didn't want to use copper red glaze as the main glaze.

The reason for this is that it is difficult to burn paper, so the quantity of copper-red glazed porcelain on the market will be small, the price will be high, and the competition will be small.

As the kiln temperature rose, Chen Wenzhe returned to the workbench again.

Pure ruby ​​red is not Chen Wenzhe's pursuit, his pursuit has always been the more difficult blue and white underglaze red.

Ruby red is so difficult to fire, so what about blue and white underglaze red?It stumped many people.

And Chen Wenzhe likes this kind of porcelain. Others can't, or it is difficult to burn paper, so he has a chance.

"By the way, how much did you sell for that pair of blue and white underglaze red peony vases earlier?"

To make ruby ​​red porcelain, Chen Wenzhe couldn't help but want to make peony bottles, because the color of peony can really express the characteristics of ruby ​​red.

"I definitely didn't humiliate you. Guess how much it sold?"

Seeing Li Jinli's proud look, Chen Wenzhe was speechless. If he could guess, how could he ask him?

However, judging by his appearance, the price should not be low.

Ordinary teapots can be sold for [-] to [-] yuan, but the pair of peony bottles he made carefully should cost more than [-] yuan, right?

"Three hundred thousand for two pieces?" Chen Wenzhe guessed.

If it's really [-] pairs, he really doesn't mind making a few more pairs. After all, it's just a good meal, isn't it just bad money?
"You underestimate yourself too much, you can do more!" Li Jinli was even more proud.

Why does he like to stare at Chen Wenzhe?Let him make more good things?

Of course, it is also for the sake of food, selling other things, where can I make money selling Chen Wenzhe's works?

You know, until now, Chen Wenzhe has not paid him a monthly salary, but only a sales commission, and it is a pure profit commission.

In other words, after deducting the cost and various expenses of each item, only one percent of the net profit belongs to Li Jinli.

Relatively speaking, Chen Wenzhe's works with little cost are the best commodities, especially those that can be sold at high prices.
