Chapter 122 The Prince is a Mediator

Clarification is also a homogenization process. Homogenization mainly relies on high temperature and convection and stirring. The temperature increases and the viscosity of the glass liquid is lower, which is conducive to diffusion. Now the splash has been reduced, but there will be a little splash occasionally. Chen Wanrong picked up the porcelain rod, and the porcelain rod is still fired according to the requirements of the crucible, in order to stir, and penetrate into the crucible and stir gently.

The temperature was too high and it was really unbearable. After stirring for a few times, even breathing. Chen Wanrong threw the porcelain rod, quickly retreated, and gasped for breath.

"Brother, what's wrong with you?" Chen Zairong was very concerned.

Chen Wanrong waved his hand and gasped, "It's okay, it's just too hot."

Chen Zairong volunteered: "I'll do it, I'm not afraid!"

"Don't show off. No one can stand it. I have to think of a way, right?" Chen Wanrong trotted to the well, dug the well water, poured it on his body, and came back with a full body of water.

Zheng Zhou frowned and asked, "Wanrong, what are you doing?"

Li Longji slapped and said, "Good solution. I'm not afraid of heat now."

Chen Wanrong held the porcelain rod and stirred it. His body was wet and felt it was not very hot anymore. Finally, he stirred it once. With this stirring, I believe that the problem of uneven glass has been greatly improved. As long as it is clarified, it can be used.

When Chen Wanrong retreated aside, his body was filled with smoke, like a steamer, which made everyone frightened. Chen Zairong urged him: "Brother, go and change the wet clothes. You will get sick when you wear them."

"No, I have to disturb you later." Chen Wanrong rejected his proposal.

After a while, Chen Wanrong wet it with well water and picked up the porcelain rod to stir. Several times in a row, Chen Wanrong was called annealing, and began the last step of melting and cooling!

The temperature is high and the viscosity is low, which is not conducive to forming. Therefore, it is necessary to cool down so that the temperature is reduced by two or three hundred degrees before forming. Take out the coal in the stove hole, and without the fire, the cooling will be much faster.

"Wanrong, it's time to eat." Chen Wangshi wiped his hands and greeted him.

It’s time to have a meal, Zheng Jianqiu and the others are ready to respond. Chen Wanrong stared at the glass: “Mom, you eat first, I’ll finish this matter before I come.”

"What else is there? It's already this day, can't I make it after eating it?" Chen Wangshi was a little confused.

Chen Wanrong had no choice but to explain: "The temperature is almost lower now. If you don't put it in the mold, you will have to start over after eating."

"What should I do?" Chen Wangshi suddenly lost her mind.

Li Longji smiled and said, "Auntie, don't worry, you eat first." He rolled up his sleeves and asked, "Shopkeeper Chen, what should I do? Let's help you."

"It's done if it's scooped into the mold." Chen Wanrong checked the mold again. He picked up the porcelain spoon, which was specially made to scoop the glass liquid. He scooped a spoonful of glass liquid and poured it into the mold. He looked closer and saw that it was not too much. Add another spoon. It was almost done. He picked up the solid body and put it in the small groove. The solid body was stable.

In order to save materials, Yuan Tiancheng's mold is not a mold, but two cups in one mold, and add four spoons per mold, and two wine glasses can be made. With Chen Wanrong's demonstration, Li Longji and the others helped, Chen Wanrong only scoops the glass liquid, and they helped to put the solid body, and it was completed quickly.

After scooping the glass liquid, Chen Wanzhi carefully looked at the crucible and kept shaking her head and sighing. Chen Zairong looked at the crucible for a while, and there was nothing strange about it. He asked in confusion: "Brother, are you sighing?"

Li Longji and the others were also puzzled. This was exactly what they were asking, staring at Chen Wanrong. Chen Wanrong explained: "The crucible is not good, look at it, it is deformed, peeled off, cracked, it is not good without graphite."

It is already very good that the porcelain crucible can withstand such high temperatures. Yuan Tiancheng has done his best and cannot expect more. As for what method Yuan Tian used to make the crucible, Chen Wanrong also asked Yuan Tiancheng.

When Li Longji and the others saw it, it turned out to be true. As Chen Wanrong said, the crucible was seriously corroded and the inner wall was peeled off, so it could not be used anymore. The topic returned to graphite. Li Longji knew the importance of graphite to Chen Wanrong and asked, "Tell me about graphite."

Graphite is an allotrope of carbon, an elemental carbon, but has completely different properties from carbon elemental diamond. It is soft, black and gray, and has a greasy feeling, and can be used to dye paper. Its melting point is above 3,000 degrees and is one of the most heat-resistant substances.

Graphite in nature is not pure and contains a lot of impurities. It needs to be processed before it can be used. You can find a way to deal with it. First, you must find graphite.

Li Longji cannot be explained according to the strict definition. Although he is extremely smart, it is beyond his understanding after all. Chen Wanrong pondered for a moment and said, "Like charcoal, it is just not burned charcoal. It exists in the wild like a mine. Once it is discovered, it will be a lot."

"I understand, I will do this when I go back to Chang'an." Li Longji agreed immediately, without any conditions, and would like to please.

The graphite crucible is a crucible made of natural crystalline graphite as the main material, plastic refractory clay as the binder, and combined with clinker. The main material is natural graphite, so it maintains the physical and chemical properties of graphite, has good high temperature resistance, small thermal expansion coefficient, and good corrosion resistance to acid and alkali. With the graphite crucible, Chen Wanrong can make glass with confidence without having to worry as he is now.

With graphite, it is completely possible to make refractory bricks and melting furnaces. Massive production of glass is not a problem, and its future is wonderful. Li Longji's words are exactly what Chen Wanrong wants to hear the most: "Thank you Prince!"

"If you do more things that are beneficial to the country and the people, you can come to me if you have any questions." Although Li Longji's words were encouraged, he also warned Chen Wanrong not to ask him for things that are beneficial to the country and the people.

Chen Wanrong understood what he meant: "Prince, please don't worry, I remember it. Go to have a meal first, and it will be cold after the meal."

It was cooled naturally, and there was no need to stay here. Everyone went to eat. There was nothing special about this meal, all of which were home-cooked dishes, but Li Longji ate very happily and applauded from time to time. When he finished eating, sweat oozed from his forehead. He commented happily: "Shopkeeper Chen, this is the most delicious meal I have ever eaten in the years. It is free and free, and I eat and chat while I am comfortable!"

In the palace, there are always people serving meals in the East Palace. It’s not like doing it here, it’s very fresh. Moreover, the food is rural. Where can he eat such authentic food in the palace? If he eats too many delicacies and occasionally eats a plate of green vegetables, it feels very comfortable. It’s really reasonable that he is so comfortable.

The hired workers knew that Li Longji was easy-going and had no airs, but they didn't expect that he would eat so casually. They sat with everyone and ate so happily, and their favor towards Li Longji increased a little.

Although Zheng Qing helped cook the dishes, it was mainly cooked by Wang Chen, because Li Longji said that she had to taste her skills. Unexpectedly, the dishes cooked with gritty teeth were praised by Li Longji. She was so happy that her eyes disappeared all of a sudden, and she said with a smile: "Prince, you are praising me! How can the chefs in the East Palace cook deliciously?"

Li Longji smiled and said, "Auntie, what you said is wrong. The dishes in the East Palace are rich, very fine, and the taste is not bad. It's just that there is no atmosphere like you eating around the table. You are always served by people in front of others, just like watching monkeys jump around the circle. Your dishes are full of country flavor, wonderful!"

The teasing words attracted a lot of laughter. The employees never expected that Li Longji would say such a joke, and they would not be able to laugh.

"The prince is so capable, there is always something to say." Chen Wang was in a good mood and couldn't help but praise him.

Li Longji took out a jade pendant from his arms: "Auntie, I'll give this to you, you've put it away."

Chen Wang hurriedly refused: "Crown Prince, this doesn't work, it won't work."

Li Longjisai was in her hands: "This is not a reward, it is a gift for you, just to think about it."

I wanted to say thank you for your honor, but when I heard this, I changed my words: "Thank you for your honor. The prince is free, so I often come to your house. I will cook for you."

"Sure, certain!" Li Longji stood up: "Shopkeeper Chen, are you okay? Let's go and have a look." While saying that, he wiped the fine sweat from his forehead, which was very comfortable.

Mrs. Chen looked at the jade pendant, her eyes shining, and she couldn't help but be happy. What else is more gratifying than the prince's gift?

Chen Wanrong responded and went out with Li Longji and the others. He came to the mold, squatted down and took a look. The mouth of the cup had condensed and formed, crystal clear, shining in the sunlight, as dazzling as pearls.

Li Longji had already seen it and high-fives and exclaimed: "Miaomiao! It's really transparent and beautiful! Shopkeeper Chen, he has a clever idea!"

Yang Sixu, Gao Lishi, and Wang Maozhong also praised him and looked at the cup in the mold in surprise.

Glass products are everywhere in modern society. What a wonderful idea? Chen Wanrong didn't argue. He said in a humble way: "The prince has been too much, and once he gets it, he doesn't dare to be the prince's reputation." When he touched the mold with his hand, it was only a little warm and almost cold: "Move back." He re-engage the two molds together, picked them up and left.

Li Longji, Chen Zairong, Yang Sixu, Gao Lishi, Wang Maozhong, and Zheng Jianqiu helped him move to the house and put it in. Chen Wanrong carefully took out the solid body and saw that the wall of the cup was as smooth as a mirror and was well cast.

Put the mold flat and separate it, revealing the high-legged glass wine glass, and a surprise sounded: "So beautiful! So beautiful!" Zheng Qing and Qing'e couldn't help but clap.

Li Longji looked at it for a while and praised it: "I know a lot of things. I haven't seen many rare treasures in the world before. This amber cup is a kind of. It's a blessing to see such a treasure today!"

Glass cups were very popular in ancient times because of their bright colors and exquisite workmanship. In comparison, glass cups did not have such complicated craftsmanship, and their main advantage was transparency, which was unimaginable to the Tang people. Not to mention that this is a modern shape, and the shape of a tall foot is bound to be popular.

Chen Wanrong put two wine glasses on the table, and everyone immediately surrounded him, stretched his neck and looked at him carefully, nodding and applauding, and was amazed.

"Shopkeeper Chen, why is this thing transparent and other things opaque? Even if the bronze mirror is polished very smoothly, the figure in the mirror will have a faint yellow color." Li Longji's talent was quick, and he began to study it in admiration.

To know why glass is transparent, you must first know why matter is not transparent. Any matter is empty from the inside of an atom, and the volumes of the atomic nucleus and electrons add up to account for a very small part of the total volume of the atom.

The reason why metals are opaque is because of the barrier of free electrons. Substances that can absorb light, benzene ring, benzenequinone, benzylline or other conjugated systems can absorb photons and thus be opaque. Transparent substances such as glass and ice are not transparent due to their breakage.

When others were amazed, Li Longji was already pursuing the whole story. Chen Wanrong praised his quick reaction from the bottom of his heart. If he really explained this, there would be more knowledge involved. Even if Li Longji was extremely smart, he would be confused. Chen Wanrong thought for a moment and said, "I also found this fun, so I made it and saw it. It should be like ice cubes, which is transparent."

This is to avoid the problem. There is no way, I can’t explain it for a while, so I can only do this. Li Longji thought for a while and said, “That’s right, ice can be transparent, why can’t glass be transparent?”

Everyone took out the wine glasses and placed them neatly on the table. At first glance, Bai Huahua was covered with crystal clear and transparent, and it was a spectacular sight.

Many hired workers rushed over and squeezed into the house, staring at the glass, and while admiring, they couldn't help swallowing their saliva, thinking that it would be great if they could take one home.

If so many glasses were put together in modern society, no one would come to see them. Even if someone came to see them, they would not be so surprised and admirable. At most, they would just talk a few words. Looking at the surprised faces, Chen Wanrong couldn't help but want to laugh.

Li Longji picked up a wine glass, looked at it for a while, and said with a smile: "Shopkeeper Chen, give me a few, how good? I have seen many rare treasures, which is not as good as this wine glass."

Even if he didn't say it, Chen Wanrong would give him a few, and the prince would come to see him in person. If he didn't give it a few, he would nod and nodded, "The prince loves him very much, and dare not disrespect him."

Li Longjiliu thought for a while and said, "I want eight."

There were only about twenty in total, and he only wanted eight, and he had a big appetite. Chen Wanrong originally planned to give two Yuan Tiancheng and a few Zheng Jianqiu, and then keep a few himself. In this way, he would disrupt the overall plan and politely reject his request: "Prince, the wine glass I made this time is good, but there are still a few problems that have not been dealt with, it is not annealed, it is fragile, and it cannot be collided. It would be better to give it to the prince."

"There are still questions?" Li Longji was very surprised.

Chen Wanrong explained: "Yes. This glass is the same as steel. It is not of good quality without annealing, so annealing is necessary. I don't have equipment in this area now, so I haven't done it. After annealing, the quality has been greatly improved and it is much better."

"It's going to be." Li Longji insisted on the original proposal, aiming at Chen Wanrong who was a little embarrassed: "That's what I think. There are male and female swords, and there are dragons and phoenixes in the cup. If one does not deserve respect, two must be polite. I want two, the father and the emperor want two, two, two of them, two of them in total, eight, how about it?"

The two princesses Jinxian and Yuzhen are closest to Li Longji. Li Longji loves these two sisters very much. When they meet good things, they naturally cannot miss them.

Ginseng gave a gift, and wine glass gave a rude thing. This was reasonable. Chen Wanrong could not refute it and nodded, "Thank you to the emperor, princess, and the supreme glory."

Li Longji was relieved. When he asked for something, Chen Wanrong would definitely not refuse. However, if Chen Wanrong was too embarrassed, he would not be willing to ask for it and smiled and said, "Shopkeeper Chen, I don't want your things in vain. I can satisfy your wish. However, I have to remind you, not to be too much." He was afraid that Chen Wanrong would make an excessive request such as the crawler camp, so he reminded him.

The prince's words certainly benefited Chen Wanrong a lot, but after all, he had to rely on himself. Chen Wanrong is the kind of person who is based on himself. Even if he doesn't remind him, he will not be too much. He thought for a while and said, "Crown Prince, let me speak with you."

It must be something that cannot be made public, otherwise Chen Wanrong would not do this. Li Longji agreed happily and followed Chen Wanrong out of the house. Seeing that there was no one around, Chen Wanrong then said: "Crown Prince, I have a reluctant request, and I would like to ask the prince to allow it."

"Tell me! If you can help, I will definitely help." Li Longji always left room for his speech.

Chen Wanrong thought for a while and said, "I want to book a marriage, but I haven't found a suitable matchmaker to propose marriage. If possible, please give the prince a golden word."

"You are bold!" Li Longji pointed at Chen Wanrong, his tone increased a lot: "I want this prince to be a matchmaker? I am illegal. I am sorry that I cannot agree."

Chen Wanrong smiled and corrected, "The prince's words are wrong. How can the prince run like a matchmaker with a huge gold body? I want to invite the prince to marry him, just one word." The prince's words are worth ten matchmakers in Chen Wanrong's mind.

"I will do my best to marry and be in a good way. Is it Miss Zheng?" Li Longji thought for a while and finally agreed.

Chen Wanrong was overjoyed: "The prince is wise!"

Li Longji folded his fists and congratulated: "Congratulations to Manager Chen. I should prepare a gift, but I came in a hurry. Please forgive me. When you get married, I will disturb you again."

"Thank you, Prince!" Chen Wanrong felt extremely honored to congratulate him with regular rituals.
