A piece of hayloft was erected by the smoking Qingque tribe's river. Under the hayloft, there are five in a group, one horizontally and one vertical alternately arranged into a block one meter wide and one meter high. , Bricks over ten meters in length.

The brick wall runs east-west, and there is a distance of more than half a meter between the bricks. This is because the east wind blows more after the winter.

This is conducive to ventilation and better preservation of bricks.

These numerous bricks are the result of the hard work of the Qingque tribe people during this period of time.

In the excavated circular foundation, Han Cheng also laid down the last brick. The two-meter arch was also declared complete.

Afterwards, he called the second senior brother and asked him to come to the top and jump fiercely to test the firmness of the brick arch.

After some jumping, the brick arch was as strong as ever, and Han Cheng smiled.

Then it took another two days to build out the internal structure of the kiln with bricks and some bricks in other places with Heiwa, taking into account the air intake and smoke exhaust.

After waiting for a few days, people will continue to pile up soil around the kiln, and slowly cover the things built before.

And all the soil was tamped with the tools used to ram the wall.

Covering the outside of the earth kiln with a thick layer of soil is useful, and the biggest function is to keep warm.

This is not a small amount of work, and it has been done for half a month before it is completely done.

At this time, rapeseed has also matured.

Han Chenggong asked most of the people to harvest rapeseeds. He and Heiwa wandered around the brick kiln carrying bone shovel, not repairing them.

Do one line, love one line, three sentences are not far from the old line, this sentence is vividly reflected in Heiwa.

He is very fond of making pottery, and he is also very fond of various kilns.

Now that he faces this kiln that the whole person feels very spacious when he enters, his expectations are even stronger than that of Han Cheng, an advocate.

Such a big kiln was something he had never thought about or dared to think about, but now he has built it like this and appeared in front of him!

If this kind of kiln is easy to use, if the time comes to make pottery, how many pottery can that kiln produce!

Looking at the brick kiln with blue smoke rising from the top of the brick kiln because it was ignited and dried inside, the black baby was full of longing thinking...

After dozens of acres of rapeseed were harvested in the field, the newly built brick kiln was completely dried. Under the command of Han Cheng, 500 bricks that had been ready for a long time were sent into the brick kiln.

Then began to ignite the kiln.

It took such a great effort to make a good brick kiln. Naturally, the capacity is more than that, but this is the first time that brick kilns are used to burn bricks in the true sense. People, including Han Cheng, are not familiar with fire conditions. Therefore, It needs to be tentative and groping.

To burn such a kiln, the firewood required is far from comparable to other small kilns. It is directly added to the burner in a whole bundle.

The flames below the kiln were raging, and there was green smoke rising from above.

This kind of fire lasted for two days and two nights before no more firewood was added to it.

The burner was sealed, and the people who had already prepared according to Han Cheng's previous orders began to use clay pots to pick up a load of water from a small river not far away, to the top of the brick kiln, and then follow along. Mouth, pour it down one by one.

The thick soil outside the brick kiln isolates the heat. Even though the temperature inside the brick kiln is terribly high, people who climb up and down outside the brick kiln with water just feel that the soil is slightly hot.

The cool river water pours into the brick kiln from above, where it meets the hot air and others, and produces a large amount of higher temperature gas, which is filled with the earth kiln...

After Heiwa poured a jar of water, she was still a little dazed. He didn't understand why the kiln was being fired properly, and why he had to pour water into it suddenly.

In this way, won't the bricks in the kiln be destroyed?

In addition to this result, he has been dealing with pottery all the year round, and he really can't think of any other results.

This kind of thing, the **** son should know better than himself, but he still let it...

This is what makes Heiwa even more confused.

Is it possible to operate like this, and there are other changes that you do not know about?

He squatted there while taking the water from others, while thinking secretly about this seemingly unreasonable and puzzling thing.

Of course there will be other changes. Without the irrigation process, blue bricks cannot be fired.

The reason why Han Cheng stubbornly wanted to burn the green bricks was not because the Qingque tribe also brought a green, and wanted this green brick to match the Qingque tribe, but under these conditions, the green brick was stronger than the red brick.

The red bricks that were common in later generations were all extruded by machines, and the density of the bricks themselves was very high, while the bricks of the Qingque tribe were made purely by hand.

Even when the bricks are made, no matter how hard you use them, the density of the bricks will be far less than the bricks of later generations.

Such bricks, the fired red bricks are easy to crisp, and under the same conditions, they are not as strong as blue bricks.

The blue brick will be gradually replaced by the red brick in later generations, almost at the point of extinction, which has nothing to do with the trouble of burning it.

After various machines were used in later generations and the kiln-firing technology was also changed, a kiln red brick could be produced in three or four hours.

It is impossible for the bricks of the kiln to be filled with water to achieve this speed.

Moreover, due to the movement of the machine, the fired red bricks are not inferior to the blue bricks, and even stronger than the blue bricks, so it is only natural that the blue bricks are replaced.

Of course, under the current conditions, for the Qingque tribe, the green brick is still the first choice.

"This way the bricks will be stronger and easier to use."

Han Cheng touched the bricks mixed with sand and gravel, and said to the black baby who had sealed the kiln and came down to inquire.

Will be stronger?

Is it sure that it won't become torn apart?

Heiwa thought about lightnovelpub.net with some doubts in her heart, but did not ask again, because he knew that what the son of God said is generally not wrong.

It's just the truth, what is it?

Heiwa scratched her hair, looking a bit distressed.

Burning the kiln for two days, filling the kiln on the third day, and then stuffing the kiln. In the afternoon of the fourth day, the brick kiln was finally opened amidst the expectations of the Qingque tribe!

Looking at the steaming kiln entrance, Han Cheng also clenched his hands nervously.

Although he knew what the final finished product of the brick kiln would look like, he still had no idea whether the brick kiln he built could produce qualified finished products. After all, this was the first kiln.

Han Cheng yelled for the black baby who was eager to know that he wanted to enter the kiln. He waited here for a while. After making sure that the inside was ventilated, he took a mask made of linen cloth stacked several layers On his lips, he went into the brick kiln.

Heiwa and they also dress in the same way.
