When Lame covered the newly made hole with the last piece of animal skin from the inside out and nailed it shut with copper nails, this great problem was finally solved.
"call!"
Lame pushed the handle of the cork to push the cork forward. After the air was squeezed, it blew away the animal skin covering the first hole, and air flowed out from there.
At the same time, the airflow generated by pushing the wooden handle will blow the animal skin nailed on the inside of the second hole tightly against the wooden board, completely blocking the second hole, and no air will escape from here.
"call!"
He exerted force on his lame arm and pulled back the cork that had been pushed to the bottom.
As he pulled, the animal skin covering the first hole was firmly sucked onto the wooden board, and no air flow came in from there.
At the same time, the animal skin covering the inside of the second hole opened up, and the outside air flowed in through the open hole.
Seeing this scene, Heiwa's face was all smiles, his face turned a little red, and he couldn't help rubbing his hands back and forth vigorously.
Bo knew what Heiwa wanted to do most at this moment, so after pushing and pulling it a few times, he simply handed the wooden handle in his hand to Heiwa.
Heiwa replaced Lame's position. After taking the wooden handle from Lame's hand, he couldn't wait to start pushing and pulling. As he pushed and pulled, his face became more and more rosy, as if he had drunk alcohol. He was so excited that he couldn't describe it.
After having the wooden bellows made by Bo, Heiwa gave up his plan to make a bellows with pottery.
Because after comparison he found that wood was undoubtedly more suitable for making this thing.
Of course, the one that Bo has just made cannot be used directly, because it is just a prototype. It is small in size, cannot generate enough wind, and there are still many imperfections in some places.
However, after overcoming these technical difficulties, it will not be difficult to manufacture a large bellows. It is just a matter of copying others.
Of course, the gourd is still in Jinguan City, and Bo and his friends have not seen it yet, but this does not prevent them from possessing this skill.
As Lame began to get busy, the sounds of clinking, saws cutting wood, and planes scraping boards could be heard again in the carpenter's room.
Time passed quietly amidst such noises, leaving behind scraps and sawdust all over the floor, but at the same time, a large bellows appeared in the carpenter's room.
Compared with the previous small experimental bellows, this several sizes larger bellows has undergone many changes.
For example, there is only one hole for letting air out, but it is larger, while there are two holes for letting air in.
However, the two holes are not as big as the one used for venting air.
This is because the pressure is too great when the air is pushed out, and the animal skin is relatively soft. If the hole is too large, the animal skin will easily be pressed out of the hole.
A wooden board was also installed on the side where the bellows handle existed to seal the entire bellows.
Of course, there is a hole for the handle on the wooden piston to move.
At the same time, the handle installed on the wooden piston has changed from one to two.
This is because during the pushing and pulling process, Bo and Heiwa discovered that if only a handle was installed in the center of the wooden piston, the wooden piston would easily tilt if not properly installed during pushing and pulling.
If you install two handles, one above and one below, you won’t have such trouble.
In order to facilitate pushing and pulling by hand, a short wooden handle that is more suitable for pushing and pulling by hand is installed at the end of the two handles exposed outside the bellows, and the two wooden handles are connected together.
In addition, the wooden piston inside the bellows has also undergone some changes compared to before.
The wooden pistons in the past were made purely of wood, but now they are covered with a layer of smooth leather without any hair.
This is mainly because during the pushing and pulling process, Heiwa and Bo discovered that a simple wooden piston could not completely block the gap between the wooden piston and the inner wall of the bellows.
The existence of these gaps means that when the wooden piston is pushed downward, a lot of wind will flow upward through the gaps.
If the wind escapes from here, the wind going out from the hole below will be reduced a lot.
After wrapping it with a layer of animal skin like this, this problem is greatly solved.
Although it is impossible to block all the gaps and prevent even a tiny bit of wind from running upwards, after such an operation, the wind running upwards was suddenly reduced a lot...
Outside the Qingque main tribe, a huge wooden bellows was being pushed and pulled, making a whistling sound.
As the whirring sound was heard, the flames inside the kiln kept rising. Even though the weather was cold now, you would still feel the heat if you got close to it.
Compared with the simple wind bellows that Han Cheng had made before, this closed bellows is undoubtedly more convenient and easier to use.
Heiwa held the handle of the wooden piston of the bellows with his hand, pushing and pulling it continuously, sending streams of air into the stove.
In such freezing weather, sweat was actually streaming down his forehead.
Heiwa didn't care about all this. He just pulled the bellows again and again, sending gusts of wind to the bottom of the kiln, just wanting to make the fire in the kiln burn more vigorously. He seemed to know no fatigue.
Looking at the blazing flames, Heiwa's heart also began to burn...
The bellows stopped breathing, and the flame gradually became smaller until it went out.
The red-hot charcoal gradually became dim, with some whitish ash appearing on it without any light.
As time passed, the charcoal lost its temperature and the warm stove slowly became cold.
A lot of people gathered around the kiln, including Wu and the eldest senior brother.
Everyone looked at the kiln which was not very warm, and then looked at Heiwa standing beside it. They all felt expectant and nervous.
Heiwa was even more excited. Although he had opened the kiln many times before, he suddenly felt like he had no idea where to start.
He shook his hands vigorously, took a deep breath, and then went to open the kiln.
As he moved, the closed kiln door was opened, and fine dust flew out from inside, revealing some whiteness.
Heiwa reached his hand into the kiln, which was not very warm, touched the utensil closest to the edge, and took it out.
When his fingers touched the instrument at the edge, Heiwa's heart couldn't help but beat violently.
Because the feeling from the fingertips is different from the pottery I have touched before.
Even glazed pottery does not have this smooth feeling.
He suppressed his excitement and carefully took his hand out of the kiln.
Everyone's eyes were on it.
Although they had never seen porcelain before, after seeing the cup taken out of the kiln by Heiwa, everyone immediately confirmed that this was the porcelain that the Son of God had mentioned!
Because this cup looks so good! So beautiful!
It completely surpassed the pottery that already existed in the tribe.
This is a qualitative leap, a leap so huge that one can tell the difference at a glance.
Before, just by hearing what the Son of God said, everyone thought the porcelain was very good. Now when they really saw this piece of porcelain that had just come out of the kiln, everyone discovered that this porcelain was even more exquisite than what the Son of God had said before!
Heiwa held the cup in both hands, with a look of intoxication in his eyes.
He looked at it carefully, not daring to make any big movements, for fear of accidentally breaking this exquisite thing.
The eyes of the rest of the people were also focused on Heiwa's hands, full of amazement.
For a moment, the place became extremely quiet, and some people even forgot to breathe.
“Let me see…”
After this silence lasted for a while, the witch's voice was heard, trembling slightly.
Heiwa then woke up from his dream, holding the porcelain in his hand, and walked carefully to the side of the witch, handing the porcelain carefully to the witch.
Wu took the porcelain that seemed to be emitting some luster, held it in his hands and looked at it carefully. His cloudy eyes became exceptionally bright at this moment.
His rough fingers kept rubbing it gently, and he was reluctant to let go for a moment.
After standing here and watching for a while, Heiwa realized that there was still porcelain in the kiln, so he quickly came to the front of the kiln and reached out his hand again to take out the porcelain.
The others also gathered around.
A large white bowl, smooth and round in surface, seems to be emitting luster under the sunlight.
A small spoon, also extremely smooth, was placed in front of my eyes and looked at in the sunlight for a while, and it seemed to be somewhat translucent...
With Heiwa's careful movements, pieces of porcelain made of kaolin were taken out one by one.
I tapped it with my hand with a little force, and sure enough, a pleasant sound came out, which was very delightful.
However, compared with fired pottery, the yield rate of porcelain is lower. Only three or four out of ten pieces can be made, and the rest are mostly broken.
But even so, it was enough to make Heiwa and the rest of the Qingque tribe happy.
People with higher status in the tribe could each hold a piece of porcelain and look at it carefully, while people with lower status could only hold a piece of broken porcelain and look at it carefully.
Porcelain is not only beautiful and lustrous, but also very hard. Some of the broken parts have thin gaps that can even be used to cut meat.
The exquisiteness of the porcelain was beyond the imagination of everyone in the tribe. They even felt that such things could only be carefully placed on display, and it was a sin to use them to hold food.
Some people, such as Wu, even think that such things can be passed down from generation to generation as treasures.
This mentality is actually mainly caused by the fact that there are too few porcelains in the tribe and the people in the tribe are seeing porcelains for the first time.
As more and more porcelain is produced in the tribe and people gradually get used to the existence of pottery, everything will be fine.
Because of the appearance of pottery that was so exquisite that it could not be described in words, the Qingque tribe was in a state of extreme excitement and joy for a period of time.
The witch has placed exquisite porcelain on the stone platform in front of the totem pole more than once, hoping that the great gods would also take a look at these exquisite things.
In fact, rather than showing it to the gods, the witch wanted to tell the good news to the Son of God who was far away in Jinguan City as soon as possible, so that the Son of God would know that the tribe had already fired the porcelain according to his instructions.
However, the Son of God is not in the tribe now, and Jinguan City is too far away from the main tribe, so it is inconvenient to pass information between them. Therefore, Wu can only pin his hopes on the very cold God, hoping that the God he is talking about will tell the Son of God who is far away in Jinguan City about this very good news...
Inside the pottery workshop, Heiwa and some other people who know how to make pottery are working hard with kaolin to make clay models.
They wanted to produce more exquisite and unusual porcelain so that all citizens in the tribe could eat their meals with exquisite porcelain bowls.
At the same time, they also wanted to use this exquisite porcelain to exchange for more food and some other things from other tribes.
In the past, pottery could be exchanged for many things from other tribes. Now, this porcelain, which is much more exquisite than pottery, can definitely be exchanged for many more things!
Heiwa and the others couldn't help but feel excited just thinking that their tribe could use one kiln to produce a lot of porcelain bowls, and could exchange them for food or other things that other tribes had collected for a long time.
This excitement is even stronger than being able to fire porcelain itself.
Because of the existence of Han Cheng, the unscrupulous son of God, the primitive people who were originally simple and honest and had simple ideas have become less simple and honest than before...
Through previous manufacturing and firing, Heiwa and his friends have discovered some tips on making clay embryos with kaolin.
For example, it is necessary to make the clay as thin as possible, which will be very difficult when making large pieces of porcelain.
As they continued to work, clay embryos made of kaolin began to appear.
Some people are still using tools to scrape off some of the excess material on the dried mud embryo to make the mud embryo smoother and more shapeable.
When a batch of clay pieces has been made, the kiln will be opened to fire the next batch.
Heiwa was never absent during the firing process.
He had been paying attention to the situation in all aspects, and recorded them in a small notebook according to the method that the Son of God had previously explained, so as to facilitate future review and identification of deficiencies.
Time passed quietly while we were busy. After dark clouds covered the sky, the dry and cold weather finally came to an end temporarily.
Without a whistle of wind, snowflakes began to fall from the sky, hitting the ground and bouncing and rolling.
However, when more snow particles gather together, the latecomers will not be able to jump anymore.
After the snow particles covered the ground with a layer of impure white, snowflakes began to fall.
While heavy snow fell in the Qingque tribe, the sun was still shining in Jinguan City in the south...
