Chapter 223: Secondary Firing Method!
The two took a rickshaw back to the workshop. It was already a hot July day, and you could feel the heat at the door of the workshop.
When I opened the door, I saw that all the craftsmen inside were shirtless, with sweat still dripping down their bodies.
Since they were not making fake artifacts, there was no previous caution.
Wei Chengbin was teaching them how to burn the kiln in front of the furnace: "After pouring the mold, the mold must not be burned by the fire, otherwise it will not be used next time, so we have to put it on the shelf..."
Wei Chengbin felt like he was back in time when his father taught him how to make porcelain.
But now he has become the teacher and the students have become a group of craftsmen.
The craftsmen watched carefully, fearing to miss any detail!
After all, this learning opportunity is rare and they must seize it.
"You guys are really busy here." Lin Ran said with a smile. Originally, he wanted to put the painting in the workshop, but now it seems that it is safer for him to keep the painting in the store.
I don't know who shouted: "Boss Lin is back."
Everyone turned their attention to Lin Ran and Li Yuanhao.
Li Yuanhao walked away as if nothing had happened, while the craftsmen gathered around him enthusiastically.
Wei Chengbin once told the craftsmen that he learned all his techniques from Lin Ran.
Wei Chengbin's skills were intimidating to them. How high would Lin Ran's level be?
They also gathered around, hoping to learn from Lin Ran.
Since they were so enthusiastic, Lin Ran decided to help them.
"Before making Tang Sancai, you should know that the full name of Tang Sancai is Tang Dynasty Sancai glazed pottery. It is a kind of low-temperature glazed pottery. The glaze contains yellow, green, white, brown, blue and black. In fact, it is mainly yellow, green and white, so it is called Tang Sancai."
The craftsmen nodded, but one stood up and said, "We already knew this."
"Are you sure?" Lin Ran smiled and picked up a work, "Who made this Tang Sancai of the lion?"
A craftsman raised his hand and asked humbly: "Boss Lin, do you have any questions?"
"You are imitating the lion three-color glaze pottery pendant, but didn't you notice that the glaze on the surface is dark? In fact, Tang Sancai should use bright glaze. When it is first fired, it will look bright and dazzling. It will last for hundreds of years. It won’t lose its softness and luster,” Lin Ran said.
The craftsmen looked at each other, only Wei Chengbin nodded thoughtfully.
"The biggest problem you have is that you plan to burn them all at once, which is wrong." Lin Ran looked at Wei Chengbin and asked, "Didn't you teach them the two-time burning method?"
Lin Ran actually knew the secondary firing method!
Wei Chengbin was touched in his heart. This was a secret of his family.
Seeing his embarrassed look, Lin Ran smiled and said: "It doesn't matter. The secondary firing method will soon be circulated in the world. There are already detailed documents in the museum, so there is no need to hide it."
"Well, I was worrying too much." Wei Chengbin nodded awkwardly, clasped his hands on his chest and looked at Lin Ran as he began to explain.
"The firing of Tang Sancai actually used a secondary firing method."
"After the Tang Sancai is made of white clay into a body, it is placed in a kiln for biscuit firing."
"After the raw body is fired, it is cooled, colored, and put into the kiln again for firing."
Lin Ran spoke clearly and the craftsmen nodded. In fact, not only Tang Sancai, but also most of the porcelain was made this way.
They were somewhat unclear about what Lin Ran wanted to express.
Lin Ran smiled and said: "The Tang Sancai you burn will be darker in color. The main reason is the temperature control."
"The temperature of Tang Sancai's plain baking is one thousand degrees, and the temperature of the second time is eight hundred degrees!"
Lin Ran remembered this sentence very clearly, because it was the result of research by several colleagues back then. They argued about it for three days and three nights, and finally came up with specific data, which was even adopted by archaeological magazines and published in on the forum.
Finally, it was recognized by professionals!
Wei Chengbin was slightly stunned. In fact, he made Tang Sancai based on instinct and did not know the specific temperature.
All I know is to burn the iron until it is close to white before firing.
Lin Ran could actually guess the temperature?How did he measure it?
The craftsmen were thoughtful and kept this in mind.
As for how to control the temperature, it is not something he should consider. This is what the craftsmen should do.
Under Lin Ran's suggestion, they happened to be carrying out the second firing work.
So, the worker in charge of opening the fire increased the heat and watched the iron inside burn red to confirm its temperature.
Lin Ran continued to discuss the details of the production with them.
"If we make handicrafts, we need to be able to tell that they are fake at first glance, but they can easily mislead other people's vision."
"For example, soldiers in the Tang Dynasty held a spear with their left hand and a shield with their right hand. We can do the opposite, holding a shield with the left hand and a spear with the right hand."
"Then, we can make slight adjustments in size. For example, if the three-color Tang Sancai soldier figurine is 72 centimeters high, we can make it about 60 centimeters, making it look more compact!"
"Of course, the most important thing is that we have to leave our own secret marks on the handicrafts we make. Even if they are bought by others, we should not be taken advantage of and buy back the sold handicrafts."
Lin Ran said jokingly, and the craftsmen also scratched their heads and laughed honestly.
The short training session is over, and the finished product of the second firing can be taken out.
Putting it aside for cooling, they continued to chat about their learning experiences during this period. Each craftsman had his own understanding, and among the three of us, there must be one teacher for me!
From their conversation, Lin Ran also learned a lot of knowledge that he didn't know before.
Sure enough, the master is among the people!
After they finished chatting, the finished product of the second firing was finally released.
There is also a Tang Sancai painting of a lion. Compared with the previous one, the color has indeed become much brighter, as if it had just been painted.
"It's exactly what Mr. Lin said. It turns out that the second time requires low temperature, and the first time requires high temperature treatment." The craftsman who had objections just now is now in admiration.
Originally, he had some opinions, but he felt that Lin Ran didn't work in the workshop at all and could only talk on paper.
But after seeing his guidance, the craftsman was completely convinced!
Li Yuanhao watched silently from the side, thinking: "I was just like him just now. Mr. Lin is really unfathomable."
Geniuses are not uncommon, but this is the first time he has seen a genius who is proficient in everything!
At least in his mind, Lin Ran was already an all-rounder.
While everyone was praising Lin Ran, there was a rapid sound of brakes outside the door.
The door of the workshop was pushed open.
I saw Yang Jianlong running in in a hurry!
