Smoking Qingque Tribe has set up a grass shed by the river. Under the grass shed, there are five groups of five, one horizontally and one vertically arranged alternately to form a wall one meter wide and one meter five high.
, bricks more than ten meters long.
The adobe wall runs east-west, with a distance of more than half a meter between each brick. This arrangement is because after the winter here, there are more easterly winds.
This is conducive to ventilation and better preservation of bricks.
These many bricks are the result of the hard work of the Qingque tribe members during this period of time.
In the excavated circular foundation, Han Cheng also laid down the last brick. The arch with a span of two meters was also declared complete.
Then he called his second senior brother and asked him to jump on it hard to test the firmness of the brick arch.
After some jumping, the brick arch was as strong as ever, and Han Cheng had a smile on his face.
Then I spent another two days working with Heiwa to build the internal structure of the kiln using bricks and some adobe bricks in other places, taking into account the air intake and smoke exhaust.
After waiting for a few days, and after it is solid, people will continue to pile up soil around the kiln, slowly covering the things that were built before.
And the soil that was carried was compacted using the same tools used to compact the wall.
Covering the outside of the earthen kiln with a thick layer of earth is purposeful, and its biggest function is to maintain heat.
This is a large amount of work, and it took half a month to complete before it was completely completed.
At this time, the rapeseed has also matured.
Han Chenggong asked most of the people to harvest the rapeseeds. He and Hei Wa walked around the brick kiln carrying bone shovels, tinkering.
Do what you do, love what you do, and stay true to your profession. This sentence is vividly reflected in Heiwa.
He loves making pottery very much, and he also loves all kinds of kilns.
Now that he was facing this kiln that felt very spacious when he entered it, his expectations were even higher than those of Han Cheng, the advocate.
He had never thought of such a big kiln, nor dared to think of it, but now it was built like this and appeared before his eyes!
If such a kiln is easy to use and used to bake pottery, how many pottery can be fired in one kiln?
Looking at the brick kiln with green smoke emitting from the high top due to the ignition of fire inside for drying, Hei Wa thought with longing...
After dozens of acres of rapeseed were harvested and brought to the field, the newly built brick kiln had been thoroughly dried. Under Han Cheng's command, 500 bricks that had been prepared for a long time were sent into the brick kiln.
Then start lighting the kiln.
The capacity of the brick kiln built with so much effort is naturally more than this, but this is the first time that bricks are fired in a brick kiln in a real sense. No one, including Han Cheng, is familiar with the heat, so
We need to explore and explore.
To burn such a kiln, the firewood required is far more than other small kilns. You just add bundles of firewood directly to the fire opening.
The flames were raging below the kiln, and green smoke was rising from above.
This fire lasted for two days and two nights before no more firewood was added to it.
The fire opening was sealed, and everyone who had already prepared according to Han Cheng's previous order began to use clay pots to carry loads of water from the river not far away, to the top of the brick kiln, and then followed the remaining
mouth, pouring one jar after another.
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 carrying 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 other gases, producing a large amount of higher-temperature gases, which permeate the inside of the kiln...
After Hei Wa poured a jar of water down, he was still a little dazed. He didn't understand why he was burning the kiln so well and suddenly had to pour water into it.
If this happens, won’t all the bricks in the kiln be damaged?
Apart from this result, he, who has been dealing with pottery all year round, really can't think of any other results.
The Son of God should know this kind of thing better than himself, but he still let it happen...
This is what makes Hei Wa even more confused.
Is it possible that there are other changes that I am not aware of when operating like this?
He squatted there and took the water from others, while secretly thinking about this seemingly unreasonable and puzzling thing.
Of course there will be other changes. Without the process of watering, there will be no green bricks.
The reason why Han Cheng stubbornly wanted to make green bricks was not because the Qingque tribe also brought a green brick and wanted the green bricks to match the Qingque tribe, but because under such conditions, the green bricks were stronger than the red bricks.
The red bricks that are common in later generations are all extruded by machines, and the bricks themselves are very dense. However, the bricks of the Qingque tribe are purely handmade.
No matter how hard you use to make the bricks, the density of the bricks that come out will still be far inferior to those of later generations.
The red bricks fired from such bricks are easy to crisp, but under the same conditions, they are not as strong as the green bricks.
Green bricks will gradually be replaced by red bricks in later generations, and are almost on the verge of extinction, which is not unrelated to the trouble of firing them.
In later generations, with the use of various machines and changes in kiln-firing technology, a kiln of red bricks could be produced in three or four hours.
Watering is also required, and it is impossible for the green bricks in the stuffy kiln to reach this speed.
And due to the movement of the machine, the fired red bricks are no worse than the green bricks, and are even stronger than the green bricks, so it is natural for the green bricks to be replaced.
Of course, under the current conditions, for the Qingque tribe, Qingzhuan 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 Hei Wa who had sealed the kiln and came down to ask.
Will it be stronger?
Are you sure it won't fall apart?
Hei Wa thought with some doubts in his heart, but did not ask any more questions, because he knew that what the Son of God said was usually correct.
But what is the truth behind this?
Heiwa scratched his hair, looking a little distressed.
The kiln was fired for two days, filled with water on the third day, and then stifled. 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 entrance filled with heat, Han Cheng also looked a little nervous and clenched his hands.
Although he knew what the final product from the brick kiln would look like, he was still not sure whether the brick kiln he built could produce qualified products. After all, this was the first kiln.
Han Cheng called to Hei Wa who was eager to know the result and wanted to go into the kiln. After waiting here for a while, making sure that the inside was ventilated, he put a mask made of linen that had been stacked several layers in.
Mouth, go to the brick kiln.
Heiwa and the others are also dressed in the same way.
