That's a lot of efficiency.

But the kiln of firing pottery, the structure is very simple, but the requirements are actually very high, so quickly built something, can it really work?

Mingshan was silent, walked to the front and took a closer look.

After just one glance, his eyes widened slightly, and he took another step forward.

At the same time, Qin Lianying, who was beside him, had already asked what was in his heart: "What kind of kiln is this?"

The kiln that burns bricks is different from the kiln that burns pottery, but there are similarities in the structure, and Qin Lianying also knows a little about it. But the one in front of him is completely different from all the structures he knows, what is this?

Xu Wen finished a job and had come back to his senses, he raised his head and looked at the chief inquisitors in front of him, stunned for a moment.

"I've seen you. He quickly relaxed and saluted.

"Is this going to be fired pottery?" Qin Lianying asked the question just now.

He walked closer and saw better.

The kiln was built along the hillside, about one and a half years tall from the outside, and a ditch was dug out of the hillside, and then stones were laid up layer by layer, paved in the shape of a step, and then capped, forming a kiln chamber from the entire ditch.

The kiln chamber is divided into several parts, and Qin Lianying is very familiar with the process of firing pottery, and vaguely identifies the respective uses of these parts.

There is a combustion chamber, a flue, a chimney, and a bottom kang......

The composition is the same as what he knew before, but the structure is completely different, he has traveled all over the country, and he has never seen it!

"Yes. Xu Wen glanced up at Jing Nanhai and said with a smile, "The adults put the location here, and the materials in the camp tent and the ready-made coal were originally planned, right?"

Jing Nanhai was noncommittal, and Mingshan was more curious about something else: "Then what kind of kiln is this?

"This is called the inverted flame kiln, which is developed on the basis of the previous rising flame kiln and steamed bread kiln. From here, the fire burned, rose to the top, blocked the way, poured down, and flowed through the kiln chamber......"

Xu Wen explained in detail, and Qin Lianying and Mingshan heard the advantages at the same time: "In this way, the temperature in the kiln is very similar!"

"You can also make large pieces of pottery. ”

"Big and small, it's flexible. ”

The eyes of the two masters lit up, and they circled around the inverted flame kiln for a long time, and saw a lot of details.

Xu Wen built this kiln quickly, but it is actually very detailed and has a lot of details.

For example, there is actually a compartment between the kiln wall and the outer layer, which is used for heat preservation. There is more than one flue in the kiln, but there are two main branches, and the branches are arranged in a non-zigzag shape, which is also for temperature control.

Obviously, this pottery kiln is by no means a work of a pat on the head, but a design that has been carefully thought out?

"Is this what you think?" Qin Lianying knew that Xu Wen's mind was very flexible, so it was logical to think so.

"No, it was designed by a local boy surnamed Ni. Xu Wen said frankly, not at all.

The inverted flame kiln in history, developed on the basis of the ancient kiln, officially appeared in the Ming Dynasty, and was originally the crystallization of the wisdom of the ancients.

However, Xu Wen did not expect to see its birth with his own eyes.

Ni Tianyang is such a person, he should not be born to take the imperial examination, his talent in physics and chemistry is too strong.

It's just that he is in this era, and he can only do some things with his strong interests, and many advanced ideas are even formally formed after encountering Xu Wen and fall into the practical category.

How many such people have been buried in such a long history?

"Surname Ni Tianyang?" Jing Nanhai suddenly asked.

"Your Excellency, do you know?" Xu Wen looked up, really surprised.

"A weirdo in Greenwood Town, I didn't expect to have this ability. Jing Nanhai said.

"Let no man be a disfigurer. There is indeed something ingenious about this kiln, and it is worth recording!" Mingshan touched his beard, took out a booklet and a pen from his sleeve, and prepared to write something on it.

He was just about to start writing when he suddenly remembered and asked Xu, "Can I remember?"

Tianshan Liuzhen Garden records the world's craftsmanship, this is what Mingshan ancestors have been doing for generations, seeing this new kiln, of course he sees the hunting heart.

But this is obviously not in line with the principles of the ancients, Mingshan asked this sentence, and immediately prepared to introduce himself.

"Please. As a result, before he could speak, Xu Wen had already nodded first, and asked him, "Do you need me to introduce you?"

He said as he walked the other way.

There, Nanyue craftsmen have just dug a new soil ditch and are ready to build a new kiln.

It is of course more convenient to explain the construction of the kiln.

"That's the best!"

Next, Xu Wen began to build a kiln while explaining to Mingshan.

He can't be dual-minded, just what he is doing, just report the name and purpose of this part.

Mingshan stood at the front, desperately recording in the book.

He's obviously used to doing this kind of thing, and he's writing very fast, and the speed of recording is amazing.

The other three were a little behind and listened carefully.

Qin Lianying is a good hand at burning bricks, and he is no stranger to firing ceramics, he listened quietly, silently comparing with what he knew.

Jing Nanhai's face was expressionless, and he didn't know what he was thinking.

Although Lin Xie has been exposed to a lot of craftsman-related things, he is not an insider after all, and he doesn't understand it.

After a while, he grabbed a young man next to him and asked, "Do you know about this Ni Tianyang?"

He happened to catch Luo Wei, who had been training in the Yinmahe cement field for a while now, and had a lot of dealings with Ni Tianyang.

Luo Wei and the others are not locals, and they don't have a deep feeling about Ni Tianyang's previous "notoriety", but because of these later things, they have a good impression of him.

Luo Wei said what he knew, emphasizing Ni Tianyang's ability and helping him say a lot of good things.

"Hmm...... In this way, this man is really interesting. Lin Xie said with a deep groan.

"The key is to really have the ability!" Luo Wei emphasized.

"Definitely. Lin Xie nodded.

"That's not right, is it?" said the two of them, as voices came from the other side.

Lin Xie turned his head and saw Qin Lianying frowning at Xu Wen and questioning.

He was stunned for a moment, then walked over to listen.

"The kiln chamber should be sealed, and your inverted flame kiln should let the fire pour down from above and distribute it evenly in the kiln chamber. As a result, you are going to use these miscellaneous stones to build a kiln now? Granite and ginger stone are the same thing? Their hardness and refractory properties are the same?

"It is true that it would be better to use the same kind of stone, but the resources in front of us are limited, and it is simple because of the ugliness, so it can only be like this. Xu asked.

"Nonsense! Because it's ugly, it's simple, and it must be usable. You're just afraid that the kiln will blow up before the thing is fired!" Qin Lianying said.

"I've thought about it...... Xu Wen thought about it, and found that it was really difficult to explain, so he shook his head and said, "Why don't I burn a kiln for you first?"
