I am a Primitive Man

By the riverside of the smoking Qingque Tribe, a piece of thatched sheds was built. Under the thatched sheds, there are groups of five, one horizontal and one vertical alternately arranged to form a block with a width of one meter and a height of one meter five. , Adobes over ten meters long.

The adobe walls run from east to west, and there is a distance of more than half a meter between each block of adobe. This is because there are more east winds after the winter here.

This is conducive to better ventilation and better preservation of bricks.

These many adobes are the result of the emotional labor of the people of the Qingque tribe during this period of time.

In the excavated circular foundation, Han Cheng also put down the last brick, and the arch with a span of two meters was also declared complete.

Then he called the second senior brother and asked him to come up to the top and jump hard to test the firmness of the brick arch.

After some jumping and jumping, the brick arch was as strong as before, and Han Cheng smiled on his face.

Then it took another two days to build the inner structure of the kiln together with Heiwa in other places using bricks and some adobes, taking into account things like air intake and smoke exhaust.

After waiting for a few days, when it is firm, people will continue to pile up soil around the kiln, and slowly cover the things that have been built before.

And the soil that was carried was tamped with the tools used to tamp the wall.

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

This is not a small amount of work, and it took half a month to complete it.

At this time, rapeseed has also matured.

Han Chengcheng asked most of the people to harvest rapeseed, and he and Hei Wa wandered around the brick kiln with a bone shovel, not tinkering.

Do what you do, love what you do, and stay true to your roots in three words, these words are vividly reflected in Heiwa.

He is very passionate about firing pottery, and he is also very passionate about various kilns.

Now facing this kiln that the whole person feels very spacious when entering, his expectations are even stronger than those of Han Cheng, the advocate.

He had never thought about such a big kiln, and he didn't dare to think about it, but now it was built like this, and it appeared in front of his eyes!

If such a kiln is easy to use, if it is used for firing pottery in time, how many pottery can be fired in that kiln!

Seeing that it is drying because it is ignited inside,

And at the high brick kiln with blue smoke coming out from the top, Hei Wa is full of longing thinking...

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

Then start firing the kiln.

It took so much effort to build a brick kiln, and the capacity is naturally more than that, but this is the first time that a brick kiln is used to burn bricks in the true sense. People including Han Cheng are not familiar with the fire, so The world needs to be tested and fumbled.

To fire such a kiln, the firewood needed is far more than that of other small kilns, and the firewood is directly added to the burner in whole bundles.

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

Such a big 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 order began to pick up loads of water from the small river not far away with clay pots, came to the top of the brick kiln, and then followed the left mouth, one jar after another poured down.

The thick soil outside the brick kiln insulates the heat. Even though the temperature inside the brick kiln is frighteningly high, people who climb up and down outside the brick kiln with water only 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, producing a large amount of higher temperature gas, which permeates the earthen kiln...

After Heiwa poured a pot of water, he was still a little dazed, he didn't understand why he suddenly had to pour water into the kiln after it was well fired.

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

Apart from this result, he couldn't think of any other results after dealing with pottery all the year round.

Shenzi should be more aware of this kind of thing than himself, but he still let it go like this...

This is what confuses Hei Wa even more.

Is it possible to operate like this, and there are other changes that I don't know about?

He squatted there while receiving the water handed by others, while secretly thinking about this seemingly unreasonable and puzzling thing.

Of course, there will be other changes. Without the procedure of water irrigation, green bricks cannot be fired.

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

The red bricks that are common in later generations are all extruded by machines, and the adobe itself is very dense, while the adobes of the Qingque tribe are purely handmade.

Even when making adobes, no matter how much effort is used, the density of the adobes produced is far inferior to the adobes of later generations.

With such adobes, the red bricks produced by firing tend to be crispy, but under the same conditions, they are not as strong as the blue bricks.

Blue bricks will be gradually replaced by red bricks in later generations, and they are almost on the verge of extinction, which is not unrelated to the trouble of firing them.

After the use of various machines in later generations and the change of kiln firing technology, a kiln of red bricks can be produced in three to four hours.

It is impossible to achieve this speed for the green bricks that need to be filled with water and boring in the kiln.

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, Qingzhu is still the first choice.

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

Han Cheng touched the adobe mixed with sand and gravel, and said to Hei Wa who came down from the sealed kiln to inquire.

Will it be stronger?

Are you sure it won't be falling apart?

Hei Wa thought with some doubts in his heart, but he didn't ask again, because he knew that what the Son of God said was usually correct.

It's just the reasoning here, so what is it?

Hei Wa scratched her hair, looking distressed.

The kiln was fired for two days, the third day was filled with water, and then the kiln was boring. On the afternoon of the fourth day, amidst the great anticipation of everyone in the Qingque tribe, the brick kiln finally opened!

Looking at the kiln mouth filled with heat, Han Cheng also clenched his hands nervously.

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

Han Cheng shouted to Hei Wa, who was eager to know the result and wanted to enter the kiln, and waited here for a while, and after confirming that the inside had been ventilated, he put a mask made of linen that had been stacked several layers on the On the mouth, go to the brick kiln.

Hei Wa and the others are also dressed in the same way.
