Liu Feng looked at the earthen kiln in front of him, just like the kind of kiln that Liu Feng had seen in the book in his previous life, but the kiln was not small, about eight meters long, three meters wide, and about one meter six high, and the slightly smaller kiln next to the left hand was seriously damaged. The flue, the kiln bed were destroyed.

"Do you know when the kiln was smashed?" Liu Feng asked

"When the bandits attacked the fort yesterday, our fortists guarding the entrance of the kiln all went to the walled gate, and I don't know who came in and smashed it." Zhaozhi said with some shame that he was responsible for the destruction of the kiln.

"Who told you to take the burghers away, or could someone get in?" A thin girl's voice complained in a low voice, Liu Feng heard the voice and looked back, he knew this girl, she was Zhaozhi's daughter, when Zhaozhi was taken in by her grandfather Liu Yunshan, she was a dirty and thin little girl, as if her name was Zhao Xuewei! Now it's a little bit long.

Zhao Zhi coughed a little embarrassed, glared at his daughter Zhao Xuewei, Liu Feng waved his hand to show that he didn't mind, after all, it was the predecessor who was impulsive and let the enemy take advantage of his own loopholes, not to mention that he didn't have such a small amount of energy to compare with a little girl.

There are several kilns near Cizhou, in addition to the kiln of Liujiabao, the Yu family in Cizhou City is also a kiln, but the kiln mouth of the Yu family is not as good as the porcelain fired by the kiln mouth of the Liu family, durable and durable, they use the same porcelain clay, but the kiln mouth of the Liu family, the temperature of the porcelain is higher than that of the Yu family, plus the glaze of their own formula, so the porcelain of the Liu family is sold well in various places.

Everyone looked at the destroyed kiln in front of them, they were at a loss, they just waited for Liu Feng's mother Bai Naren to come back and couldn't solve it for a while, it was not so easy to build a kiln, it was necessary to constantly debug, and there were enough refractory bricks, how to maintain the temperature in the kiln was the most important. They watched Liu Feng look left and right beside the kiln entrance, opened the kilns, and entered the kiln room to see, which was a little inexplicable.

Zhao Xuewei was even more disgusted with Liu Feng, she knew that Liu Feng usually didn't come to the kiln except for practicing martial arts, how could he know how to repair the kiln, but watching Liu Feng turn around, her mouth kept muttering, she was full of curiosity.

Liu Feng carefully observed the kiln, their kiln is a coal-burning kiln, but because of the change of fuel, the kiln has changed slightly, and the change is not very large, so even if this kiln is not smashed, Liu Feng will have to rebuild it.

"Ok! It's not too difficult, let's discuss it together and see how to build another kiln. Liu Feng, who finished watching the kiln, breathed a sigh of relief, and he vaguely remembered the approximate proportion of the kiln bed, fire chamber, and chimney where coal was burned.

After Liu Feng finished speaking, he took Zhao Zhi and they returned to the conference hall, Zhao Xuewei also secretly followed behind, Zhao Zhi was a little embarrassed, and Liu Feng didn't take it seriously.

"Our kiln is a coal-burning kiln, which is different from the previous firewood-burning kiln, even if it is not smashed, I think it will be rebuilt, but the kiln is smashed, we have to check this matter, and we will calculate this account later! Now I have an idea to build a kiln and discuss it with a few uncles. Liu Feng said.

Liu Feng walked to the table and picked up a pen to draw his impression of the coal-fired kiln, in fact, it is very simple, the current kiln in Liujiabao is an oval kiln, with three chimneys, the area of the fire chamber and the kiln bed is 1:2.8, and the temperature of Liujiabao is increased by sacrificing the number of porcelain. Now Liu Feng painted an apple-shaped kiln.

A kiln is simply divided into six parts: fire channel, kiln door, fire chamber, kiln bed, smoking hole and chimney, and one of the cores is the area ratio of kiln bed, fire chamber and chimney. In the kiln painted by Liu Feng, the plane of the kiln chamber is apple-shaped, the fire passage is generally shortened, the kiln door is narrowed, the fire chamber area is smaller, the ash pit is greatly deepened, the kiln bed area is increased, and the chimney area is increased.

As soon as Liu Feng finished painting, the picture was copied by Zhao Xuewei, who had already peeked at the side, Zhao Xuewei originally wanted to see this guy's joke, she had already found that the current kiln was a little unreasonable, and she had already told her father and Lord Liu Bao, but there were more and more orders for porcelain, and she couldn't verify her idea for a while.

Until Liu Feng drew the picture, she had some ambiguities in herself, and she was also determined, looking at Liu Feng's picture, the words of the dog crawling, and the lines of different thicknesses, she was also full of curiosity.

As soon as Liu Feng's picture was in the hands of the expert, it was not worth mentioning, so Liu Feng returned to the council hall and said his thoughts. Everyone in the conference hall is engaged in matters related to kiln firing, except for Bayar, who doesn't know anything, everyone looks at the picture drawn by Liu Feng, and they all feel that there is some truth, and even some speculation is that the kiln making map left by the Liu family very early.

With the map and the planned area ratio, the most important thing in Liujiabao is clay, and everyone worked in a hurry.

Liu Feng commanded on the spot, everyone was in full swing, he and Zhao Xuewei had a pair of talking, and slowly he found out that this girl is a master of porcelain art, whether it is the selection of clay materials or pulping, embryonic, drawing, glazing, kiln, she is talking about the head is the way, fortunately Liu Feng himself is also a master of porcelain burning. In particular, he is clear about the sintering temperature of each clay.

The more Zhao Xuewei and Liu Feng chatted, the more speculative they became, Zhao Xuewei seemed to have found someone to talk to, and discussed everything she knew about porcelain burning with Liu Feng, and in the heated discussion between the two people, the kiln was built.

The kiln they built has a door 0.6 meters wide and 1.5 meters high. The fire chamber is semicircular, 5.9 meters long from north to south, 1.6 meters wide from east to west, and 1.9 meters deep with the kiln bed. The kiln bed is 6 meters long from north to south and 2.7 meters wide from east to west. Two large chimneys are located side by side at the back of the kiln chamber, with a circular plan, made of bricks, with a diameter of 1.4 meters and a height of about 2.8 meters.

A group of people looked at the kiln they built, and at this time, the largest kiln in Cizhou, if the temperature can be reached, the porcelain burned by Liujiabao can be sold more and more. The next step is to coat the outside of the kiln with a thick layer of clay to ensure that there is no hot gas leakage and smuggling air pouring into the kiln.

Next is tomorrow's test burning, everyone is very worried, the big kiln next to him has been built several times before it succeeds, I just don't know, what will happen to this kiln, of course, Liu Feng and Zhao Xuewei are also nervous.

This is the first time the two of them have built a kiln, they are full of expectations, and they are really verifying their ideas, Liu Feng and Zhao Xuewei entered the kiln, making the final preparations, originally women were not allowed to enter the kiln, but before everyone had time to explain the reason, Zhao Xuewei was pulled into the kiln by Liu Feng.

Zhao Xuewei blushed and followed Liu Feng into the kiln. Seeing that Liu Feng seemed to be like a normal person, he was coated with refractory clay on the kiln bed, and he was a little angry for a while.
