This is also a good thing, which is beneficial to the people. There is nothing wrong with Chen Wanrong of course agreed: "It's fine if the prince said it's okay. Then ask Master Wang to help you do it."

What an honor to do for the prince. Wang Zhongze never dreamed of such an honor. He kept saying, "Do it well, it must be done well!" He has never spoken loudly, but today he made an exception: "If I can't do it well, I won't be a carpenter in the future."

Li Longji smiled slightly and praised: "Master Wang has good skills and will definitely do a good job!"

The prince was praised by his ancestors, and the king's face turned red: "Thank you, the prince's golden mouth!" The other carpenters' eyes were full of admiration, and they wanted Li Longji to praise them.

Li Longji looked at the bellows and asked casually: "Shopkeeper Chen, where are you planning to use for making bellows? It's not like cooking."

With a unique vision, if someone else wants to think that Chen Wanrong is used to cook, there will be no such question. Chen Wanrong replied: "Back to the prince, this is a tool for making glass. If there is no bellows, it will not be hot enough and it will be difficult to make."

"What is glass? Can you make it for me?" Li Longji was curious.

Although Chen Wanrong's historical knowledge is not good, he still knows a lot about Emperor Minghuang. He appreciated Li Longji's early push to the full rise of the Tang Dynasty. In his later period, he sighed with regret and regret. His feelings for Emperor Minghuang were very complicated. Now facing the future Emperor Minghuang, Chen Wanrong deeply felt his extraordinaryness, grand, wise, extraordinary demeanor, lofty ambitions, and a gaze. It makes people convinced from the heart. He believed that it was appropriate to meet his requirements: "The prince must see it, but there is nothing wrong with it."

"What? You say, it depends on whether I can do some effort." Li Longji planned to help Chen Wanrong make glass. He is the prince, and he wants people and power. If there is any difficulty, it will definitely not be a problem to help solve it.

Chen Wanrong knew what he meant. Not to mention the prince, even the emperor could do it: "You have to wait until the mold is done before you can do it."

"Shopkeeper Chen, are you here?" As soon as Chen Wanrong finished speaking, Yuan Tiancheng's voice sounded. He came in from outside, looked at it for a moment, and asked, "What are you looking at? There have been so many people."

They were watching the prince pulling the bellows, and they couldn't say this. Chen Wanrong smiled and said, "It's okay, a little new thing will make the shopkeeper Yuan laugh. Manager Yuan, but the mold is ready?"

"That's it, that's it. Can I not rush to do what Manager Chen wants? Manager Chen, please come and have a look." Yuan Tiancheng turned around and walked out, and Chen Wanrong followed.

Li Longji was extremely smart, and his thoughts flashed and he knew the truth. He nodded and followed him out.

If these hired workers miss the opportunity to see the prince up close, they will definitely regret it for the rest of their lives. It will be very happy to say that to their children and grandchildren in the future. Li Longji has no airs and is very easy-going. He knows that the hired workers regard him as a strange thing, but he doesn't care and let them see it. Naturally, the hired workers will not leave behind and follow them.

When I arrived in the yard, I saw a mold placed on the carriage. Chen Wanrong picked up one and saw that the wooden board was a cover, and there was pressed soil inside. There was a pit on the soil, half of the cup-shaped side. The two were put together to make a wine glass. Adding a solid body, it was completely in line with his own requirements.

What made Chen Wanrong most happy was that Yuan Tiancheng was unique. There were four horizontal mud strips on the solid body, and four small grooves on the mold, which could fix the solid body so that the thickness of the wine glass was very uniform and there would be no thicker and thinner on the other side.

"Okay, okay!" Chen Wanrong was particularly satisfied with his change and kept praising him.

Yuan Tiancheng smiled and told him: "Shopkeeper Chen, don't forget my amber wine glass." If he had given him a gold and silver cup, he might not have wanted it. The glass wine glass was fresh and unique, and he would have wanted to have it long ago.

"Sure, certain!" Chen Wanrong agreed.

Li Longji asked, "Oh, Shopkeeper Chen, can you actually make an amber cup? A clever hand!"

In ancient China, amber was believed to be a tiger soul and could be used as medicine to treat diseases. In addition, it can also be used for viewing, but it is too difficult to make wine glasses, so Li Longji asked this question.

Chen Wanrong shook his hand: "It's not an amber cup, it's a glass wine glass. But the name is not good, so it was changed by Manager Yuan."

Li Longji nodded, Yuan Tiancheng looked at Li Longji with extraordinary temperament and handsomeness. Cheng Yijia's young master suddenly felt good and bowed with fists: "Yuan Tiancheng is brave, dare to ask the young master for a big shot."

"Shopkeeper Yuan is so serious! I met Shopkeeper Chen at the time of the lower Dou Ji. I came to visit him today and met Shopkeeper Yuan unexpectedly. I am very lucky!" Li Longji did not want to disclose his identity as a prince, but still met under a pseudonym.

Yuan Tiancheng has a lot of affection for Li Longji: "Mr. Dou is a good young man. Yuan Tiancheng will meet the young man today, and he will be lucky in his three lives." If he knew that this was the prince, it would not be lucky in his three lives, but for generations.

Li Longji smiled: "It's easy to say, it's easy to say!"

Chen Wanrong asked someone to move the mold down and put it aside. Yuan Tiancheng said goodbye. Li Longji clasped his fists and joked: "Speak of Cao Cao, Cao Cao is here, shopkeeper Chen, is it time to start construction?"

"Okay!" Chen Wanrong also wanted to verify the refractory performance of the crucible and lay the foundation for the future large-scale production of glass.

Li Longji rolled up his sleeves and said, "Shopkeeper Chen, I will help you what you want to do." Yang Sixu, Gao Lishi, and Wang Maozhong also looked eager to try.

Chen Wanrong could not have thought that Li Longji would help, and shook his hands: "The prince's body is worth ten thousand gold, this is absolutely impossible."

Li Longji smiled happily: "There is no prince today, only Li Longji and Manager Chen, just treat it as Dou Ji coming to visit."

"The prince doesn't know that this glass is very dangerous and has high heat. If it splashes a little on the body, it will be a hole. If something happens, I can't afford it." The melting temperature of glass is very high and the splash is also very powerful. If one accidentally splashes on the body, a hole will definitely burn. The prince's gold is so precious that it is a serious crime. Chen Wanrong is unwilling to take such unnecessary risks.

Li Longji was determined to look at the strange thing: "Shopkeeper Chen, if you don't say this, I can consider not helping. Since there is such a risk, I still have to do it. You have to know, if there is no risk, how can I succeed?"

Born to be unwilling to give in and like to take risks is Li Longji's personality. This personality was manifested when he was young. When he was seven years old, he participated in court sacrificial activities. At that time, Wu Zetian was in power and Wu clan was in power. Li Yizong retreated. When Wu Yizong took his child seriously, he scolded his guard. Li Longji became angry and stared at Wu Yizong and shouted: "This is my Li family's court. What's your business? How dare you scold my guard!"

Wu Yizong was so strange that Li had to retreat when he met him. Unexpectedly, he scolded a seven-year-old boy on the spot and was stunned. He had no choice but to complain to Wu Zetian. Not only did Wu Zetian not blame Li Longji, but instead appreciated his courage.

It is both fresh and risky to do glass. It is a matter of his temper. Chen Wanrong was stunned when he heard him speak with no room for maneuver. After thinking for a while, he said, "The prince must do it, but he has to listen to me."

Li Longji's face sank, "I am the prince, I can't listen to you, I have to do it myself."

Chen Wanrong was not showing any weakness: "If this is the case, I would rather offend the prince than take risks. The prince should know that the popularity is so high that even if the wood hits it, it will ignite. The prince does not know that if it splashes on his body, I can't afford to be guilty, and it's better not to do it!"

"I am the prince, and it's useless to speak?" Li Longji was very surprised. He didn't take his words seriously, and there was no other one except Princess Taiping. Chen Wanrong actually rejected it. He really couldn't imagine that.

Chen Wanrong shook his head: "The prince's words are wrong! It's useful or not. It depends on the situation, it's reasonable, and of course it's useful. If it doesn't fit the situation, it's a mistake. The prince should know that these skills have their own reasons. If you don't follow the reason, it will be a big mistake. By then, it will be too late to regret it!"

Staring at Chen Wanrong, after a while of old age, Li Longji chuckled and said, "There is no one who can make Li Longji obedient yet, you are the first one! However, I also have the conditions, you have to let me do it."

"As long as the prince follows the principles, he will do nothing!" Chen Wanrong did not expect that Li Longji would agree.

Li Longji smiled and said, "There are not many people who can convince me. You are the one. How to do it? Tell me!"

"Prepare first!" Chen Wanrong asked Xiao Shangrong to find something, pack the quartz sand, and then pour some of the smashed feldspar and limestone into it. The limestone was requested from the kiln, and they were all long-term trading, so you won't give it to me if you want something.

Make hot water, pour it into a container, add Glauber's salt, soda ash, and charcoal powder, and make people turn it over for a while. The ingredients are all done.

Glauber's salt and carbon powder are added to improve the clarification effect of the glass. Quartz sand and feldspar contain impurities, which will decompose during the melting process and a large amount of gas will precipitate. The gas will escape, but not all gases can escape. A small amount of gas will remain in the melting liquid, and bubbles will form after processing, affecting quality.

In addition, the decomposition temperature of some components is too high, and the decomposition of gas is delayed, forming bubbles and reducing quality.

In order to improve the quality of the glass, the clarification effect must be increased. There are many measures, including prolonging the melting time, increasing the clarification temperature, stirring and gas, boosting or vacuum, ultrasonication, and using clarification agents.

Stirring and stimulating, boosting or vacuuming, ultrasonic waves were unreachable in the Tang Dynasty. There were only three ways to extend the melting time, increase the clarification temperature and use clarification agents.

The most commonly used method is to use clarification agents. Commonly used clarification agents include nitrate, arsenic trioxide, Glauber's salt, ammonia sulfate, antimony trioxide and fluoride. Among these clarification agents, the most suitable one is to use Glauber's salt, because it can be bought in pharmacies. Glauber's salt is the most commonly used clarification agent. The effect of using Glauber's salt alone is not very good, and adding carbon powder will greatly improve its effect.

The reason why water is added is because water is beneficial to the melting of glass. The main benefits are reflected in several aspects: First, adding water can moisten the surface of the sand particles and form a water film, which strengthens the melting and adhesion ability to flux, and good contact speeds up the reaction process.

Second, water enhances the viscosity of the mixing material, stabilizes the position between the particles, makes it easy to blend evenly, and reduces stratification.

Third, water can increase heat conduction during melting, making the mixing material easy to melt.

Fourth, moisture becomes steam when heated, which can turn the glass liquid and bring out small bubbles, promoting clarity and uniformity of the glass liquid.

Fifth, it can reduce flying materials and reduce corrosion on refractory materials. It can reduce dust, which is beneficial to health.

He asked someone to bring the crucible, bellows and coal, put them in the bellows, and then put them on after a little debugging. Xiao Shangrong and others poured the material into the crucible and most of the pot was poured into the crucible.

"These are all stones, can they be burned?" Li Longji was a little puzzled.

It is normal for him to have this question. Among the people present, except Chen Wanrong, there are such doubts. After all, burning the stones in the Tang Dynasty was a difficult thing to believe. Chen Wanrong said confidently: "It must be! The prince should know that steelmaking also starts with stones? As long as it is hot enough, it will definitely be able to be transformed!"

"It makes sense!" Li Longji brimmed his high fives.

Chen Laoshi touched his forehead: "Wanrong, even if it can be burned, what can these sand do?"

"Dad, this is not sand, it is quartz sand. You can't make glass without quartz sand." Chen Wanrong had to explain to him.

Chen Houshi still didn't believe it: "That's not the case. Solid and iron are good stones used for making steel and iron. They are useful. Is your sand OK?"

"Will you know if it's OK." Facts are better than words, so it's better to speak with facts. Chen Wanrong put the lid on the crucible and half-covered it.

If it is covered, the gas will flush the lid and can only be covered halfway. The reason for covering it is to prevent splashing. The temperature rises and the gas escapes, and the splashing is quite severe. Coal should be added in front of the stove and the bellows should be pulled. It should not splash in front of the stove. The front half should be covered.

"Then I have to take a good look! If Manager Chen can really make good things from the sand, I will reward you with great rewards!" Li Longji was excited and prepared to watch the show.

Chen Wanrong smiled and said, "I dare not think about the reward. If I encounter difficulties, the prince will be grateful for it if I can help me solve it." Although gold, silver and jewelry are cute, they have no raw materials and the equipment is attractive.

Now doing chemical engineering, Chen Wanrong deeply feels the difficulties caused by insufficient equipment. To solve these equipment, it is impossible to rely on himself alone, and he has to rely on other forces, especially the power of the court is more important, because the court has skilled craftsmen. At that time, as long as the prince’s words are said, Chen Wanrong will benefit a lot.

"Okay, if there is any difficulty, just say it and I will try my best to help you." Li Longji spoke with a sense of decent attitude, without taking on too much, leaving room for nothing.

It would be enough to have his words, which can be worth tens of thousands of taels of gold, even more than tens of tens of taels of gold. Chen Wanrong shoveled the coal into the stove hole and lit the fire. Before Chen Wanrong could speak, Chen Zairong grabbed the pull rod and pulled it. The wind blew, and the flames in the stove hole suddenly rose up, making it much brighter.

Chen Wanrong took care of the fire, Chen Zairong pulled the bellows. After a while, Chen Wanrong asked, "Is your hands sore?"

"It's okay!" Chen Zairong blurted out without thinking.

Chen Wanrong looked at him: "Don't be stubborn, it will take a long time, and you can't hold on anyway."

Yang Sixu walked up and said, "Brother Chen, let me give it a try."

"I dare not help Lord Yang!" Chen Zairong hurriedly declined.

Yang Sixu grabbed the pull rod without saying a word: "How can you play with this new thing alone? I have to try it out!" He pulled the pull rod and praised: "Not bad. But if this thing is pulled for a day, it will be exhausting. Fortunately, we have too many people, so we can take turns to pull it."

Gao Lishi and Wang Maozhong rolled up their sleeves and said in unison: "If you are tired, say, I'll do it!"

The bellows were fresh things. After a while, everyone was no longer interested and turned their attention to the crucible.

Not long after, the water in the crucible began to evaporate, and the smoke was swaying, mixed with alkaline smell, which was very bad, and everyone couldn't help but retreat. It happened that Gao Lishi was pulling the bellows, pinching his nose, and holding it back. Chen Wanrong reminded: "Eunuch Gao, get out of the way, and it's okay to pull it when the smoke passes. The fire is still strong, so don't worry."

After only a while of this, Gao Lishi was really unwilling to accept it, but it was so uncomfortable that he had to let go. Everyone stood in the distance, stretched their necks and tiptoes on their toes, looking at the cauldron, the smoke rising up, and could not see anything.

When the smoke was getting smaller, Gao Lishi went back to pull the bellows. Gao Lishi, Wang Maozhong, Yang Sixu, and Chen Zairong took turns to pull the bellows. In the end, even Li Longji couldn't help but pull the bellows, and then stood in the distance and looked at the crucible.

The temperature is getting higher and higher, with the crucible as the center, emitting inaccessible heat, and it is impossible to get close. Fortunately, Chen Wanrong is foresighted and has set the ventilation pipe very close, otherwise it would be impossible to pull the bellows if it was so hot.

Li Longji is the prince, and no one dares to stand in front of him. Standing side by side is also a ritual. Chen Wanrong stood half of his shoulder, and the rest stood behind him, staring at the crucible, not letting go of even a slight change.

"Look! There have been changes, there have been changes!" Chen Laoshi's eyes widened the biggest, and he was the first to discover the changes in the crucible and shouted excitedly.
Chapter completed!
