Han Cheng looked a little disappointed when he looked at the unburned sticks that were revealed after the soil was dug up.
It turns out that this method cannot burn out carbon.
The tree sticks that were pulled out were very similar to those that were burning and suddenly doused with water. They were all covered with a layer of black carbon on the outside and unburned wood on the inside.
This thing is far different from the carbon that Han Cheng saw in later generations, and it cannot be called carbon at all.
Although he thought this method was a bit mysterious before he uncovered it, he still had some expectations. Now that he uncovered the truth, it was inevitable that he would feel a little disappointed.
Wu, who stood aside and watched, was also filled with disappointment.
He had been expecting last night that the firewood that was solemnly buried in the earth by the Son of God would undergo some changes, preferably more firewood would grow out.
Now that he saw the result was like this, he felt uncomfortable.
I felt that the broad road I was thinking of was much further away from the tribe, and there were faint signs of being completely blocked by thorns...
Han Chengxian was a little troubled. He only had a partial understanding of charcoal making, and his first attempt failed. He had no good solution for the time being.
Looking at the people surrounding him who were looking at him in confusion, he asked them to continue with the work they had not finished yesterday.
Tietou and others went to harvest thatch, lame and wood, cut off the wood sections, burned them in the fire, and then polished them.
Han Cheng squatted beside the fire pit, which looked a little messy. He picked up a piece of dark wood that was burned outside as if he didn't give up, and put it in front of his eyes to study it carefully, with a look of thinking in his eyes.
In this situation, Han Cheng suddenly wanted to recite a poem, which was the famous "Charcoal Seller" written by Bai Juyi.
It’s not that I lament the difficulty of making charcoal, sympathize with the old man’s difficulty, or feel indignant that the palace market disturbs the people, but it reminds me of some of the charcoal seller’s experiences in making charcoal.
A charcoal seller was cutting firewood to burn charcoal in the southern mountains. His face was dusty and smoky, his temples were gray and his fingers were black...
The opening two sentences describe the hardships of the charcoal seller making charcoal, but Han Cheng saw something else through this layer.
It's just that his method of burning charcoal really doesn't work.
Because judging from the experience of the charcoal seller, he is most likely a lonely man, old and weak. If he uses the method used by Han Cheng to burn charcoal, not to mention the rest, he is just covering the burning firewood with sand.
This is very difficult to do.
Because the covering process was slow, these branches were all burned by the fire. Where would there be any carbon left on them?
Han Cheng didn't know what others read from "The Charcoal Seller", but he definitely understood from it that his method was not working, although he couldn't explain the reason clearly.
Wu stayed here with Han Cheng for a while, then got up and went back to the tribe. After hesitating for a while, he came to the edge of the rabbit circle, where he lay down and played with the rabbits every day.
It's just that compared to the past, when I petted the rabbit today, I seemed a little absent-minded.
Han Cheng squatted there and thought for a long time. When he stood up, his legs were numb. After staying in the same place for a while, he gradually came out of this sour feeling.
He called Hei Wa, and together they walked to the earthen kiln near the river holding firewood.
As the weather gets colder, Heiwa has not made clay embryos for pottery for several days.
Hei Wa and Han Cheng put the firewood they were holding on the edge of the earth kiln. They couldn't help but feel a little confused. The last batch of clay embryos had been fired a few days ago. At this time, Shenzi was holding firewood again.
What did Chai do when he came to the earthen kiln?
Could it be that this earth kiln is used to burn charcoal?
Hei Wa is not a stupid person. He quickly guessed Han Cheng's intention after contacting what Shenzi had done before.
But the confusion in my heart became even more intense.
He is the only one in the entire tribe who has dealt with this earthen kiln the most. The earthen kiln is well ventilated. Once you put in the firewood and light it, it will burn brightly.
Now that the Son of God has brought so much firewood and put it into the earthen kiln, wouldn't it all be burned? Where can there be the kind of charcoal left behind that the Son of God said...
Han Cheng was also thinking about this matter in his mind, but he didn't have much clue. He could only try a little bit and find experience from failure after failure.
With Hei Wa's help, firewood was put into the kiln where the clay embryos were originally placed, and firewood was also placed under the kiln.
The top of the earthen kiln was blocked by two large ceramic plates. After Hei Wa took out the original version of the fire folder and blew out the flames, he looked at the Son of God with inquiring eyes.
Han Cheng naturally knew what Hei Wa meant, and after a slight hesitation, he nodded gently.
After receiving Han Cheng's confirmation again, Hei Wa no longer hesitated, first lit the hay, and then the dry firewood. Not long after, the match at the mouth of the stove below the earthen kiln, which was specially used for making fires, was already burning brightly.
Not long after, the firewood placed in the earthen kiln also started to burn.
With so much firewood burning together, the fire was very strong. Even though the earthen kiln was covered with ceramic plates, the hot flames still came out of the gaps around it and jumped up to Lao Gao.
Looking at all this, Hei Wa suddenly remembered that the Son of God had people cover the burning firewood with sand yesterday, and couldn't help but feel a little anxious.
After all, this earthen kiln has great uses, and he spent a lot of effort to build this earthen kiln. Wouldn't it be a pity if it was buried like this?
Then he looked back and forth to one side, and found that the two of them were Shenzi himself, and he didn't carry a bone shovel. It was obvious that he would not bury the earthen kiln, which made him, who loved kilns, feel relieved.
But he soon realized that something was wrong. If it wasn't covered with sand, wouldn't the firewood placed in the earthen kiln have to burn out?
Han Cheng had already considered this before, the burning of flames requires oxygen, and he still had this basic common sense.
After watching the fire for a while, Hei Wa was asked to go to the side first and move the large broken pottery pieces and some stones discarded there to the edge of the earthen kiln.
After waiting for a while, Hei Wa used these things to block the burning hole under the kiln bit by bit.
As the burning hole shrinks little by little, the air entering it gradually decreases, and the flame loses its previous arrogance and becomes much smaller.
It's just that the flames in the earthen kiln are still not completely extinguished. This is related to the gap at the burner port under the earthen kiln. After all, Heiwa used pottery pieces to block the burner port, so it is impossible not to leave some gaps.
Han Cheng is also confused now. Should he not completely seal the fire opening? He is worried that the firewood inside will be completely reduced to ashes, so he should seal it completely. He is also afraid that the firewood will be like what he pulled out from the ground today.
It's half-baked, which is also uncomfortable.
After struggling with this for a while, I finally decided to burn it like this once to see if it didn't work. Next time, I would mix mud to completely seal the burning hole.
