On the way, Shen Hao and Zhao Yungong and Sun Da explained some of the practices of burning bricks, and he actually had a lot of questions in his heart about why the master wanted to make bricks. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

But what! The feeling that Gongsun Xu gave them was really amazing, as if they were omnipotent immortals, able to bring them completely unimaginable things.

After Gongsun Xu inspected the site where Shen Hao's raw materials and bricks were dry, he felt that he was generally satisfied.

At this time in the late Han Dynasty, Shen Hao was able to do such a situation, which can already be said to be commendable, and it is really impossible to expect him to be the same as the managers of later generations.

Gongsun Xu saw that the chimney above the brick kiln was still emitting faint black smoke, and he immediately understood that this brick kiln should have just been extinguished, and he was waiting for him to come here to see the bricks.

Shen Kuo should have refined a few kilns before, and the red bricks he made should be basically consistent with what he said, otherwise, according to Shen Kuo's calm strength, he would not easily call himself here to see the situation when the bricks were opened.

The brick kiln was slowly opened under Shen Kuo's command, and a lot of steaming heat came out from the entrance of the brick kiln, and a heat wave came directly to the face, making Zhao Yun and Gongsun Da and the others feel very uncomfortable.

Although they didn't adapt, curiosity still occupied most of it, and they forced their spirits to look like Gongsun Xu as a treasure.

Since Gongsun Xu led them here to see this burning brick with such fanfare, he naturally had the truth of Gongsun Xu.

To their utter disappointment, the brick kiln was nothing more than red stones, and they didn't feel that such things could be of any use.

Gongsun Xu is different from several of them, he knows the value of these bricks in his heart, and he knows that after the appearance of red bricks, it will change many of his current lives.

The firing of red bricks in the Tufa is very simple, but Zhao Yun Hanyu and Gongsun Da and others were confused by Gongsun Xu, and they really didn't understand what Gongsun Xu could do with such a thing.

Shen Kuo told them that Gongsun Taishou was going to build a house with this kind of thing, which made several of them even speechless. There are countless big trees and stones outside Xiangping City, and it's not okay to build houses with stones and big trees, but now you have to work hard to get such a thing, isn't that the same as taking off your pants and farting?

Gongsun Xu saw the brick factory kiln in later generations, and was very satisfied with Shen Kuo's kiln opening this time, if it was unexpected, the brick firing was very successful.

It's just that Gongsun Xu forgot one thing, that is, it takes a long time to cool down after the kiln is opened.

When producing bricks, the bricks are generally burned inside and out with a large fire, and then the fire is extinguished to cool the kiln and bricks naturally.

At this time, the air circulation in the kiln and the abundance of oxygen form a good oxidation atmosphere, so that the iron element in the brick is oxidized to ferric oxide.

Since ferric oxide is red, it will also be red.

The time to burn the bricks is slightly longer, and the natural cooling time after the kiln is not very long, as long as the brick kiln can enter the people, as long as the bricks can be taken out.

If you want to engage in architecture in this era, many things in later generations cannot be referenced, and you can only move forward step by step according to the most basic and primitive things.

After the successful firing of this kind of red brick, except for part of the chimney for building the steel-making blast furnace and the workshop for building the steel-making blast furnace, the rest of the red brick Gongsun Xu was ready to use him to build the military camp.

In this era, many soldiers in the barracks will freeze sick in winter, and if you build a house with red bricks, and make a modern kind of big kang inside, you can basically meet all the heating problems.

The inside of Xiangping City is better, because of the city wall, there is not so much wind in the city in winter, and it is not as cold as outside the city.

However, most of the houses outside Xiangping City are thatched or wooden, cold in winter and warm in summer, which is a hundred times more tragic than the most dilapidated houses in the countryside that later generations of Gongsun Xu saw.

No matter how sunny it was outside, it was pitch black when you entered the house.

A few wealthy families lived in houses made of rammed earth, and a hole was cut in the wall and hung on it with a wooden board, which was considered a window.

Once it was winter, they had to seal the windows with mud, otherwise the cold wind would blow in.

Every time winter comes, a large number of people freeze to death.

A thought flashed in Gongsun Xu's heart, now here in Liaodong, whether it is a large family or a small household, the kind of charcoal basin is used for heating, and it can be said that it is freezing to death in winter.

Even large families can't afford to use too much charcoal to keep warm for the winter.

If he had set up a professional team to build a fire kang at this time, and bought some of the red bricks by the way, then he would have made a large part of his wealth just before the winter began.

The premise is that the brick kiln of his brick factory can burn enough bricks, and he can promote this kind of fire kang at this time, and if the fire kang is promoted, the coal will naturally be marketed.

After Gongsun Xu came up with the matter of building a kang kang, no matter when the red bricks in the kiln could be formed, he would immediately draw a drawing of the construction of the kang and let some craftsmen start to test the operation now.

Gongsun Xu told Zhao Yun and Gongsun Da that they would let Shen Hao get some food at the brick factory at noon, and they would eat here at noon today, and he would find a few craftsmen to discuss some things.

The process of building a kang is very simple, as long as anyone can build a building, it can be built, but in this era, there is no stone as flat as red bricks, and no one can think of using a kang to keep warm.

If he really starts to build a fire kang according to his ideas, not only the red bricks he has developed now, but also the large amount of coal he mined some time ago, it will have an extremely broad market.

The most important point is that now he is the Taishou of Xiangping City, as long as he sets an example, other big businessmen will follow suit.

When you make a fire to cook, the house will be burned warm, and you can stay on the hot kang at night or during the day, which is definitely a fairy-like day for the cold Liaodong.

Gongsun Xu thought of a lot of things through the matter of building the ondol, as long as he can succeed in the two things of the kang and coal, at least until the spring of next year, he can no longer have to worry about the lack of money in his hands.

Zhao Yun and Gongsun Da Han Yu looked at each other, and they didn't know that Gongsun Xu was playing with the above moth.

Several of them were very dissatisfied in their hearts, and this Gongsun continued to get a few of them to the brick factory to see the bricks, and before they could see the bricks, they looked at some soil and early things, and there was no shadow.
