    This step is glass melting, which is to obtain a uniform, transparent, and pure glass liquid to prepare for forming.  There are five more steps in the melting stage, and there are no obvious boundaries between these steps. Often one process has not ended before the next process begins.

    The first step is the silicate formation stage. This stage is generally between 800 and 1,000 degrees, and the ingredients undergo a series of chemical, physical, and physicochemical changes.  The main changes are the heating of the powder, evaporation of water vapor, decomposition of salts, polycrystalline phase transformation, melting of components, and solid-phase reactions of quartz sand and other components.

    The temperature has just come up now, this process is going on, and it is not melting.  Chen Laoshi was preconceived and thought it was melted.  As soon as he started shouting, everyone joined in, and that was how he got such momentum.

    Yang Sixu was blowing the bellows. When he heard this, he couldn't hold it in any longer. He put down the bellows and ran over to take a look. He was surprised: "It's really transformed! It's amazing!"

    Li Longji¡¯s insight was astonishing, and he frowned: ¡°Don¡¯t talk nonsense, it¡¯s melted somewhere, it¡¯s stronger.¡±

    The first stage will not melt, but will form a sinter of silicate and free silica, which is opaque and denser. Li Longji¡¯s words hit home.

    After talking about it, everyone finally saw it clearly, and they all asked: "It's already like this, can it be burned?" In their impression, it is very rare for a stone to be burned like this, which is beyond their imagination.  .

    "It's almost there." Under the current circumstances, it can be heated to a high temperature of thousands of degrees. Chen Wanrong was very satisfied and confident. He looked at the sintered object with interest and said: "It will start to melt after a while."

    Although everyone does not understand what melting is, they are not in the mood to investigate now. It is only right to be optimistic about the changes in the crucible. If a small detail is missed, it will be a huge loss and a pity.

    Wang Maozhong's interest greatly increased, and he strode over and said, "I'll pull it!" He grabbed the lever and pulled it hard, and the stove hole burst into laughter.

    "I'm going to add coal!" Chen Zairong volunteered without waiting for Chen Wanrong to do it. He came to the stove and put a lot of coal in: "If you need to add more, it's done!" After adding coal, he trotted back and looked at the crucible.  , as if afraid of missing a detail.

    At this time, everyone felt nervous, no one spoke, and no one could hear their breathing.  Chen Wanrong was also nervous. What he was most worried about was that the crucible could not withstand such a high temperature.  Although there is nothing wrong now, the temperature will be higher after a while, and it may deform or crack. In that case, all the efforts will be wasted.

    Time passed silently, the opaque sintered objects began to sink, and transparent liquid appeared in the crucible. Chen Wanrong could not restrain his excitement and shouted: "It's done!"

    "Look, it's really melted!" Everyone started talking and pointing at the crucible, extremely surprised.  They had never smelted steel or iron, and it was the first time in their lives that they had seen the burning of stone. It was beyond their imagination and they were not surprised.

    Li Longji's observation skills were much stronger, and he couldn't help but nod: "Transparent, like water. Shopkeeper Chen, can this thing make an amber cup?" Although Li Longji was very smart, he just wanted to make the glass as transparent as water.  It was still difficult for him to understand that liquid glass was made into a wine glass. After all, it was beyond his comprehension.

    "Prince, don't worry, if nothing happens, it will definitely work!" Chen Wanrong said without a doubt.

    Li Longji looked at Chen Wanrong and asked, "What's the accident? Is there a way to deal with it?"

    Chen Wanrong said worriedly: "What I'm most worried about is that the crucible will be burned, deformed and cracked. If this happens, it won't be possible. If there is graphite, we can make a crucible that is more resistant to burning, and it will be foolproof."  .¡±

    Porcelain crucibles can generally only withstand high temperatures below 1,200 degrees, and it will be very troublesome if it exceeds 1,200 degrees.  The temperature at which molten glass forms is around 1,200 degrees, which is the current temperature.  This has entered the second stage.

    " Staring at the crucible, fortunately there was no deformation or cracking. Chen Wanrong breathed a sigh of relief, but he still did not dare to take it lightly, because the temperature behind it was even higher, and that was the real test.

    Li Longji looked at the crucible and asked, "What is graphite? Where can I find it? Tell me, and I'll see if I can send someone to help you."

    Chen Wanrong heard this and felt happy in his heart. To make glass, you must have graphite, and he didn¡¯t know where to find it. If Li Longji was interested, he would get twice the result with half the effort: "Thank you, Prince!"

    "But let's make an agreement first! I helped you, what benefits do I get?" Li Longji's shrewd side showed up, and he didn't suffer at all.

    If Chen Wanrong had not heard it with his own ears, he would not have believed that the dignified prince actually cares about such small profits. He only heard Li Longji continue:"

    After all the talk, there was no way to persist, so Chen Wang had no choice but to go.  Looking at her back, she is not walking, but floating, or flying. The prince wants to taste her craftsmanship, how can she not be so happy that she floats?

    Zheng Qing smiled sweetly and followed.  Chen Wanrong was relieved. Zheng Qing was good at cooking. With her help, she could deal with it.

    Then he looked back at the crucible and saw that the splashing was getting worse. Li Longji frowned and said, "If it keeps splashing like this, it will be gone after a while."

    Chen Wanrong smiled and said: "Prince, please be relieved, no. After a while, there will be less splashing." He looked at the crucible, motionless, as if there was a treasure on the crucible.

    Chen Zairong touched him: "Brother, what do you see?"

    "I was checking to see if there was any change in the crucible. Now is the time for the test." Chen Wanrong was very worried.  After melting, it should be clarified, and clarification requires a very high temperature, usually between 1,400 and 5,000 degrees.  Such a high temperature has long exceeded the endurance range of the porcelain crucible, so there is nothing to worry about.

    After looking at it for a while, fortunately, there was no change.  I don¡¯t know what method Yuan Tiancheng used to find out how the porcelain crucible can withstand such a high temperature. I have to ask him.

    "Zairong, help me place the mold." Chen Wanrong returned to the house and brought the mold.

    Li Longji, Yang Sixu, Gao Lishi, Chen Zairong, and Zheng Jianqiu came to help and moved there in one go.  After setting up the mold and looking at the crucible, there is still one more step to make the wine glass.  (To be continued.
