Chapter 28 The method of firing pottery without building an earthen kiln

On the second day, the eldest brother did not lead the people out to hunt after eating as usual, but walked to the small river with Han Cheng, the seven or eight children and the lame.

Along with Wu and other people in the tribe, they were very curious about what good things the Son of God had come up with.

After one night, these mud embryos have dried a lot, and the water on the surface has disappeared. With a light touch, you can feel that these mud embryos are much harder than yesterday.

Wu looked at the things in this area, thinking in his eyes. If these things are really hard enough, they can indeed hold a lot of things, and it is really, as Shen Zi said, far more useful than stone bowls and stone basins.

But the key is that this thing is made of mud, how could it be strong?

Wu was very puzzled, even though he had the knowledge passed down from generation to generation of witches, he couldn't figure out what method the Son of God would use to harden these things made of mud.

Wu is very smart. He knows that the mud is not solid. The Son of God must know it. Since the Son of God knows this and still says and does it, there must be a way that he does not know to make the mud firm.

Use fire, burn.

Han Cheng spoke his way in Mandarin.

It's just that Wu and the big brother were even more confused after this method was told, because in their cognition, fire can burn many things away!

Shouldn't the mud become looser when it is burned with fire? How is it possible to become strong?

There is no way to communicate, because it is too much effort to explain this series of things!

Han Cheng had no choice but to use the old method to attribute all this to the gods. He did not explain too much himself, but explained it with the final results, which could save a lot of tongues.

After coming here for a look, not only did he fail to understand but was even more confused, the elder brother went hunting with everyone who was equally confused, while Han Cheng took the little guys in the cave and continued to make mud embryos.

Wu didn't go back, but watched Han Cheng and the minors in these tribes playing with mud.

Watching them make these mud into strange looking things, Wu also joined the ranks of playing with mud after roughly figuring out the process...

On the third day, the mud embryos made on the first day were half dry. Han Cheng looked at more than fifty mud embryos placed on the ground, and temporarily stopped making mud embryos, but began to lead These people collect things like dead grass, fallen leaves, twigs.

Because it is spring now, and people here do not have the habit of setting fire to the slope, so there is a thick layer of dry grass on the ground.

These minors, after hearing that through fire, they can make the things they made by themselves strong, have already been aroused with strong interest.

It's not too tiring to work hard one by one.

By the afternoon of that day, a large pile of hay and firewood had already been piled up nearby.

On the fourth day, the first batch of mud embryos produced was almost dry. Due to the weather, except for three cracks, the rest were intact, and Han Cheng was secretly relieved. In one breath, it can be regarded as a good start, right?

Han Cheng threw away the three broken ones, and circled a place of about two square meters nearby again. He had someone dig it down to a depth of 30 centimeters, and then spread a layer of hay on it.

With the help of the big brother and others who came to see the rarity, the mud embryos made on the first day were carefully placed on the hay and arranged neatly, leaving a gap of about five centimeters between each mud embryo.

Then, under Han Cheng's demonstration, everyone filled the gaps with the hay and firewood collected yesterday, and pressed the porcelain with their hands.

Then the withered grass was broken into smaller pieces, mainly the burn-resistant stalk-shaped withered grass, and these mud embryos were covered with each covering about ten centimeters, and they were tried to be compacted by hand.

Then we continued to plant the grass until the tank made by Heiwa, which was over one meter high, was covered and the cover was increased by more than ten centimeters, then it stopped.

So far, all the pottery has been covered by the broken grass, not revealing the slightest.

Just when many people, including Wu, thought that the fire could be started, Han Cheng gave them an order that surprised them.

Han Cheng did not let the fire be lit, but asked someone to fetch water from the river, wet the excavated floating soil and mix it with mud.

Different from the relatively hard mud used in making mud tires, according to Han Cheng's request, the mud this time is softer and can be called thin mud.

Well, Hei Wa, Zhuang and the others are just making love with each other now...

Under the watchful eyes of everyone, Han Cheng picked up the mud and paste it on the pile of firewood covered by the mud embryo. From top to bottom, the firewood and grass must be sealed up wherever it passes, until the firewood and grass cannot be seen from the outside.

After the Heiwa and the others came down these days, they were already familiar with playing with mud. After having Han Cheng's demonstration and receiving Han Cheng's orders, they began to imitate Han Cheng's appearance and pile up firewood from different angles. Paste thin mud.

At the bottom of the firewood pile, Han Cheng did not let Hei Wa and the others do it, but made it by himself.

Around the ground, four gaps of 20 centimeters square were left, which were not sealed with thin mud.

Send the fire.

Han Cheng opened his mouth, and he didn't need to appoint a candidate. Junior Brother Sha, who was watching here, had already quickly ran towards the cave.

Although he didn't understand why the Son of God acted like this, he could still feel the difference from this series of orderly steps.

Here comes the fire.

Han Cheng took the burning tree trunks from Junior Brother Sha, moved them to the four vacant places, and lit them one by one.

Because the previously crushed withered grass leaves were used for filling, and they were pressed into porcelain by hand, so they will not burn quickly, and even the open flames are not very good.

Especially after confirming that the fire will not be extinguished, Han Cheng sealed the four ignition ports with thin mud, leaving a small hole with a diameter of less than half a centimeter for each to ventilate, and the flame inside burned even more slowly. up.

Relieved, Han Cheng told Wu, senior brother and everyone that it would take three days to know the result.

This made everyone anxious to know the result a little anxious.

But there was no other way, everyone stayed here for a while, knowing that the elder brother would not be able to see the result in a short time, he took the hunting team out to hunt.

In spring, when the glaciers melt, swimming fish are not as easy to catch as in winter. Hunting wild animals has become the main source of food for Duluo.

Wu did not go back, but stayed here with Han Cheng and others.

After playing around for a while, under the call of Han Cheng, a group of underage primitive people started to make mud embryos again.

However, different from their concentration in the past, today they seem a little absent-minded. From time to time, they will turn their heads to look at the mud-sealed pyre, hoping that the silent pyre will bring magical things earlier.

Not to mention them, even Han Cheng looked at it from time to time, and sometimes crawled to the ground and looked through the small hole to see if the fire inside was extinguished.

After all, this is also his first time making pottery, and he just watched the video once, and he still has no idea whether it can be done in one go.
