Clarification is also a homogenization process, and homogenization mainly relies on high temperature, convection, and stirring. As the temperature increases, the viscosity of the glass liquid decreases, which is conducive to diffusion. Now that the splashing has reduced, there is only an occasional small splash. Chen Wanrong picked up the porcelain rod. This porcelain rod was still fired according to the requirements of the crucible. It was used for stirring. He inserted it into the crucible and stirred gently.
The temperature was too high and it was unbearable. After just a few stirrings, he couldn't even breathe. Chen Wanrong threw the porcelain rod away and stepped away quickly, gasping for air.
"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 come, I'm not afraid!"
"Don't show off, no one can bear the heat. I have to think of a way, and I have it." Chen Wanrong trotted to the well, fetched the well water, poured it on his body, and came back drenched in water.
Zheng Zhou frowned and asked, "Wan Rong, what are you doing?"
Li Longji gave a high-five and praised: "What a good idea. Now I'm not afraid of the heat."
Chen Wanrong held the porcelain rod and stirred it. My body was wet and I didn't feel very hot anymore, so I finally stirred it once. With this stirring, I believe the problem of uneven glass has been greatly improved, and it can be used as long as it is clarified.
When Chen Wanrong stepped aside, smoke was rising from his body like a steamer, which shocked everyone. Chen Zairong urged: "Brother, go and change the wet clothes. Wearing them will make you sick."
¡°No, we¡¯ll have to stir things up later.¡± Chen Wanrong rejected his proposal.
After a while, Chen Wanrong soaked it with well water again, picked up the porcelain rod and stirred it. Several times in a row, Chen Wanrong, which is called annealing, began the last step of melting, cooling!
High temperature and low viscosity are not conducive to forming, so cooling is required to reduce the temperature by two to three hundred degrees before forming. Take out the coals from the stove hole. Without the fire, the cooling will be much faster.
"Wanrong, it's time to eat." Mrs. Chen Wang came over to greet her while wiping her hands.
It¡¯s such a big day, it¡¯s time to eat, and Zheng Jianqiu and the others are ready to respond. Chen Wanrong stared at the glass: "Mom, you eat first, I'll come back after I finish this."
"What else is there? It's been a day, why can't you eat it and cook it again?" Mrs. Chen Wang was a little confused.
Chen Wanrong had no choice but to explain: "The temperature has almost dropped now. If you don't put it in the mold, you will have to start from scratch after eating."
"What should we do?" Chen Wang lost her idea.
Li Longji smiled and said, "Don't worry, Auntie, you eat first." He rolled up his sleeves and asked, "Shopkeeper Chen, what should we do? We'll help you."
"Scoop it into the mold and it's ready." Chen Wanrong checked the mold again. Pick up a porcelain spoon, which is specially used to scoop out glass liquid, scoop up a spoonful of glass liquid and pour it into the mold. I took a closer look and saw that it wasn't too much. I added another spoonful and it was almost there. I picked up the solid body and put it into the small slot. The solid body was flat and stable.
In order to save materials, Yuan Tiancheng¡¯s mold does not make one cup, but two cups. Add four spoons to each mold to make two wine glasses. With Chen Wanrong's demonstration, Li Longji and others helped, Chen Wanrong only scooped up the glass liquid, and they helped put the solid body in, and it was quickly completed.
After ladling out the glass liquid, Chen Wanzhi looked at the crucible carefully, shaking his head and sighing. Chen Zairong looked at the crucible for a while. There was nothing strange about it, so he asked in confusion: "Brother, how much do you sigh?"
Li Longji and the others were also puzzled. This was exactly what they wanted to ask. They stared at Chen Wanrong. Chen Wanrong explained: "The crucible is not working. You see, it is deformed, peeled, and cracked. It cannot work without graphite."
It is already very good that the porcelain crucible can withstand such a high temperature. Yuan Tiancheng has tried his best and cannot expect more. As for how Yuan Tian made the crucible, Chen Wanrong still wanted to ask Yuan Tiancheng.
Li Longji and the others took a look, and sure enough, as Chen Wanrong said, the crucible was seriously corroded, the inner wall was peeling off, and it could no longer be used. 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, which is elemental carbon, but has completely different properties from carbon elemental diamond. It is soft, dark gray, greasy, and can be used to dye paper. Its melting point is above 3,000 degrees, making it one of the most heat-resistant substances.
? Graphite in nature is not pure and contains many impurities. It must be processed before it can be used. You can find a way to deal with it. You must first find the graphite.
We cannot explain Li Longji according to a strict definition. Although he is extremely smart, it is beyond his understanding. Chen Wanrong pondered for a while and said: "It's the same as Tan."Otherwise, Chen Wanrong would not do this. Li Longji readily agreed and followed Chen Wanrong out of the house. Seeing that there was no one around, Chen Wanrong said: "Prince, I have an unkind request, please grant it."
"Say it! If I can help, I will definitely help." Li Longji always left room for words.
Chen Wanrong thought for a while and then said: "I want to arrange a marriage, but so far I have not found a suitable matchmaker to propose marriage. If possible, please give me a word from the prince."
"You are brave!" Li Longji pointed at Chen Wanrong, his voice raised a lot: "You want me to be a matchmaker? It is against the law, I am sorry that I cannot agree."
Chen Wanrong corrected him with a smile: "The prince's words are wrong. How can the prince, who has a body of thousands of gold, run around like a matchmaker? I want to ask the prince to marry me, and it only takes one word." The prince's words are enough to be worth it. Top ten matchmakers in Chen Wanrong¡¯s mind.
"The marriage is a matter of human ethics, and I will take it upon myself to fulfill it. Is it Miss Zheng?" Li Longji thought for a while and finally agreed.
Chen Wanrong was overjoyed: "The prince is wise!"
Li Longji clasped his fists and congratulated: "Congratulations to shopkeeper Chen. I was supposed to prepare a gift, but it came in a hurry, so please forgive me. When you get married, I'll have another glass of wedding wine."
"Thank you, Prince!" Chen Wanrong felt extremely honored that he congratulated him with common courtesy.
Li Longji smiled and said, "Just wait, I'll do it right away." He strode into the house. (To be continued. If you want to know about the funeral, please log on to www.qidian.com. There are more chapters. Support the author and support genuine reading!) (Remember the website address: www.hlnovel.com
