Porcelain clay, also known as kaolin, is formed by the flow of potassium, sodium, calcium, magnesium and other elements within feldspar and mica, plus hydration. It is the main raw material for firing porcelain.

Of course, Jiang Xingchen didn't know porcelain clay, he just felt like it, because the feel of those powders was as smooth as silk. In his last life, he heard from his classmates in Jingdezhen. But in the end, it still needs to be real.

In addition, even if it is porcelain clay, it is very different. He didn't know the specifics, but he knew that in the previous life, some places could be fired at 1,100 degrees, while others needed a high temperature of more than 1,400 degrees. As for the melting point of porcelain clay, it is generally about 1,700 degrees, but he only has a vague impression of these.

The process of firing porcelain, Jiang Xingchen is also unclear, but he has craftsmen who fire pottery at hand. Because the most complicated thing about firing porcelain is hanging glaze, he doesn't need it now, even if the porcelain is burned, it's fine, the main thing is to test the temperature, and then go back and study the crucible. It is important to know that porcelain is also deformed at extremely high temperatures.

Jiang Xingchen was very excited at the moment, and asked where he found it, and this mine must be obtained.

Seeing that Jiang Xingchen was so excited, Xian Ning was a little stunned, pointed to the side and said, "You ask him!"

Jiang Xingchen turned his head, and saw a young man in private soldier clothes bowing down and saying, "Back to my lord, this material was found in a place called Pingyao Town, three hundred miles away from the imperial capital. There's a barren mountain there, and there are quite a few of these stones on it!"

Jiang Xingchen frowned, and said in a low voice: "Is it a place directly under the empire?"

"Yes, it should belong to the Empire!" replied the young man.

Jiang Xingchen thought for a moment. He raised his hand and patted the young man on the shoulder and asked, "You are my personal soldier, what is your name?" Who's in charge?"

"Lord Hui, his subordinate is called Jia Chen, and he is under the jurisdiction of Captain Du Rushan!" replied the young man.

Jiang Xingchen nodded and said, "Good job, I will mention this matter to Du Rushan when I go back!"

The young man was overjoyed, and the lord personally promised that this was going to be promoted, and his salary would rise by at least fifty percent! Then he staggered and ran.

After Jia Chen left, Xian Ning asked, "Xingchen, can this porcelain clay really be made into a crucible?"

"I'm not sure. It's better to be real first...... If it really happens, then think about how to get this mine from the hands of the Empire...... By the way, I just heard you think of a way to build a kiln!"

Xian Ning was speechless and patted Jiang Xingchen gently. Angry: "I just said all the feelings in vain......."

Three days later. In the room in the research institute, Jiang Xingchen held a fine white porcelain bowl in his hand, and let out a laugh, what Jia Chen got back was really porcelain clay, and this small bowl was burned by the pottery craftsman after studying it for three days.

What made Jiang Xingchen even happier was that this porcelain clay was different from the porcelain clay on the earth. In the first two days, there were three furnaces in a row, and they were all fragments. These fragments were melted when he increased the temperature inside the kiln to 1,500 degrees. Still not deformed. This shows that the crucible made of this porcelain clay. Eighty percent of them are no problem.

Xian Ning is also laughing, although it has only succeeded in a small bowl in the past three days, the refractory performance of porcelain clay can already be determined, if the refractory brick is designed around it, it will definitely be better than the previous design, and the glass will be able to be produced.

"This little bowl is so beautiful, it feels better than jade!" Xian Ning reached out and snatched the porcelain in Jiang Xingchen's hand.

Jiang Xingchen said with a smile: "When the glaze is hung in the future, it will be more beautiful when it is fired!"

"If this thing is made, the effect is probably not less than that of glass, at least the current utensils will be greatly impacted......" Xian Ning thought for a while and said.

"That's natural, don't you see that those potters are like crazy, crying and shouting and begging me to get some more porcelain clay!" Jiang Xingchen said.

Xian Ning couldn't help but smile dumbly when she thought of the appearance of those craftsmen, she was even more excited than she was when she saw a new research project. When this porcelain bowl was burned, a group of old men burst into tears.

"Xianning, if you add porcelain clay to the ingredients of the refractory bricks, it is estimated that the effect will be better!" Jiang Xingchen said.

"I think so too, but you still have to come to the construction of the kiln, because the high temperature is required, the internal pressure must increase, and I can't grasp the shape and internal structure of the kiln!" Xian Ning said.

"Hmm!" Jiang Xingchen nodded, he must come to the construction of the kiln, and he is not at ease if others do it, in case the fryer is broken.

"Also, this china clay mine...... If we go there to dig, the empire will definitely not let us!" As soon as he said this, Xian Ning frowned.

Jiang Xingchen fell silent when he heard this, thought for a while and said, "It's okay, I'll figure out a way, this mine must be won!"

After finishing speaking, Jiang Xingchen instructed Xian Ning to have a good rest, and then turned around and left the research institute.

Walking on the way back, Jiang Xingchen's eyebrows became more and more wrinkled, just now he said that he was relaxed, but he didn't have any bottom in his heart, after all, it was a direct territory of the empire, not a certain territory, if he wanted to take it, he had to face the emperor directly.

"How can you open your mouth with the emperor, do you want to give up some of the technology?" Jiang Xingchen muttered, from his own point of view, he didn't want to let go of the technologies of papermaking, cement, sewing machines, soap, and perfume, because now the productivity is low, the market is in short supply, it is the time to make a lot of money, he must monopolize in the past two years, and it may not be enough for a few big projects to consume. If he lets it out, the production will increase, the price will definitely fall, and he will not be able to play himself.

"It's a headache!" Jiang Xingchen patted his forehead, weighed left and right, and finally gritted his teeth: "Even if you exchange technology, you have to get your hands on this porcelain clay mine." As long as the porcelain and glass are fired, you can earn back any money!"

Jiang Xingchen made up his mind and strode back, preparing to write a letter to the emperor, and by the way, fool the marshals and them, and let them help say something kind......

At the same time as Jiang Xingchen returned, in the Xingchen Leader Amusement Park, a terrible scream made a large number of tourists look sideways.

"I'm not going, I'm not going to kill me!Help!" the second prince clutched a tree trunk with both hands and shouted hoarsely. The six princesses beside him were full of anger. I was tugging at his arm.

Many tourists were attracted by this scene, pointing and whispering as they passed by.

"Damn! Are young people so popular nowadays? This is the rhythm of going backwards!"

So did the young man. Since you don't want to go to the stars with the girl, what are you doing?"

"This young man looks like a victim, is it useful to hold the trunk, and he can't go back to the hotel sooner or later!"

"Why the hell can't I meet this good thing...... Female rascal, let go of that slutty year and come at me!"

The sixth princess was so angry that her face turned blue, and the second brother's courage was too small, isn't it just bungee jumping. What's scary, listen to what those people in the back say.

If this is given to ordinary people, they will not go, so they should avoid it quickly. Don't let people see the jokes. But the sixth princess is different, the more this is the case, the more angry she becomes, and the more she wants to drag the second brother onto the jumping platform.

"Second brother, you are also a prince. Don't be so cowardly. Listen to what the people behind are saying!" the sixth princess tugged the arm of the second prince.

"I don't care what they say, I just don't go! I've been playing sled with you five times in the past three days, and if you don't want to bungee jump, you don't talk nonsense, I've never seen you bully people like this!" The second prince had tears in his eyes, completely ignoring his image, and roared loudly.

"Whether you're going or not, if you don't go, I'll tell you who you are. Look at what kind of face you have!" the sixth princess threatened.

"If you have the ability, you can say it, depending on whether someone believes it or not....... even if someone believes it. Let's see if your sixth princess is disgraced or my second prince is disgraced!"

"You...... Second brother, I'm really welcome!" the sixth princess said angrily.

"You want to go!" the second prince didn't shout now, and a hint of joy flashed in his eyes. For the first time in so many years, he had the upper hand over his little sister.

The sixth princess straightened her eyes, and suddenly hugged the arm of the second prince and shook it vigorously: "Second brother, please, will you accompany others to play a bungee jump, is ......it okay once?"

"Hiss~" The second prince shuddered suddenly, and goosebumps fell to the ground in an instant, can you not be like this!

At this time, another passer-by shouted: "Sister, that man is useless, you should be coquettish with me, I will take you to bungee jumping!"

"Shut up!" The sixth princess turned her head suddenly, her face sank like water, and said loudly: "Talk nonsense again, grandma will cripple your mouth!"

"Yo! The little girl is quite horizontal, I don't know if this is ......" The tourist didn't finish speaking, and it was dark in front of him, and he was slapped on the mouth, and the person flew out at once.

"I'll go, someone dares to beat people in Xingchen Ling!" Many tourists were shocked, even if people from big families come here in a proper manner, it is really rare to see such a cheat.

The beaten bone got up from the ground, and the other person was fine, but his mouth hurt hotly. When I looked closely, I saw an old man standing opposite, staring at him like a knife.

The man was about to scold, but he was frightened by the eyes of the great worship, and the words that came to his mouth were swallowed again. Don't look at this slap just now, but the next slap won't be certain.

"What's the matter, who was shouting for help here just now!" a security officer ran over.

"It's okay, it's okay, brother and sister are having fun!" replied lightly.

The vigilante frowned and looked at the tourist who had been beaten...... The tourist originally had the intention to complain, but when he thought of the murderous gaze of the great worship, he didn't dare to speak.

Seeing that the tourist didn't speak, the security team could only warn: "Don't make such jokes, it will affect our work, you should pay more attention to safety!"

The security guards left, and the tourists who owed their mouths were slapped in the face, but they were not injured and left in a hurry. Only then did the second prince realize that it was a bit of a big fuss, so he hurriedly let go of the big tree, and let the sixth princess drag him to the place of bungee jumping with a bitter face.

As soon as they walked on the front foot, the old man on the back foot appeared, staring at their backs and muttering, "Why are they here too...... I have to tell the little soul about this!"

Xingchen Ling, Jiang Xingchen just wrote a letter to the emperor, and before he could send it out, the old man found it. After listening to the old man's description, Jiang Xingchen's eyes rolled and said with a smile: "It's such a coincidence, it really takes no effort to come here!" (to be continued......)
