[Please do not study the details of making pottery]

The reddish-brown clay found by the river is used as the raw material for making pottery, and a stone slab with a slightly raised back is selected as a runner, and then some dried firewood and grass are collected in just three steps, and the preparation for making pottery is completed, and two other clansmen need to cooperate.

Placing the raised side of the stone slab that was used as a runner on the ground, Su Yan took a small ball of clay and smoothed it into a circle that was only the size of an adult's palm, which was the bottom of the pottery.

After that, Su Yan took the clay again, kneaded the clay into oblate and round strips, kneaded the clay into oblate strips, and made round clay circles, and then stacked the clay rings one by one, and a semi-finished product of a bowl-shaped pottery embryo was formed.

At this time, the two clansmen needed to play, Su Yan asked the two clansmen to squat opposite each other on both sides of the slate, hold the edge of the slate with both hands, and then work together to make the slate rotate in a counterclockwise direction in place.

The rotation speed of the slate is relatively slow, but with the current poor conditions, it can only be done, and better tools will definitely appear in the future with Su Yan's efforts, but not now.

Of course, Su Yan could also make the two clansmen use force to speed up the rotation of the slate, but at this time, the rotation state of the slate was relatively unstable, which was not suitable for Su Yan to take the next step.

After the rotation speed of the slate stabilized, the semi-finished pottery embryo on the slate also rotated steadily, Su Yan stretched out a pair of small hands, and slowly smoothed the semi-finished pottery embryo inside and out, and finally formed the embryo of the finished product.

Su Yan is also making pottery for the first time, and it can be said that the finished embryo is ugly and ugly, and the thickness of each area of the embryo is also different, some thick and some thin.

Su Yan looked at the finished embryo and was in a good mood, although this ugly embryo is a defective product, but this is also a pottery embryo, how can he be unhappy when he successfully made an embryo.

Putting the first completed embryo in the sun, Su Yan continued to make the next embryo, and under such primitive conditions, Su Yan didn't know how low the chance of successfully firing the embryo into pottery was, so he could only make a few more embryos and explore.

On the first day of trying to make pottery, Su Yan made a total of sixteen embryos, and the first embryo took the longest time to make, and the first embryo was the ugliest and the worst quality.

In the subsequent attempts, Su Yan's speed of making embryos became faster and faster, and the appearance of the embryos gradually conformed to Su Yan's aesthetic concept, and the quality was slowly improving.

In the afternoon of the next day, Su Yan divided the 16 pottery embryos that had been dried into two batches, first laid out two places with firewood and grass in the open space, and then placed the two batches of pottery embryos on two piles of firewood and grass, and then covered the pottery embryos with firewood and grass, and finally lit two piles of firewood and grass to fire the pottery.

The flames were blazing, and Su Yan stayed quietly not far from the fire and watched the pottery embryos in the fire.

In Su Yan's memory, he vaguely remembered that firing pottery required a constant temperature, and the best way was to put the pottery embryo in a pottery kiln for firing, which made it easier to control the temperature and improve the yield of pottery.

In addition, in the process of making pottery, Su Yan also thought of a simple but very important thing - brick making.

The pottery embryos have been made, isn't it simple to make bricks, and this brick doesn't need much hardness, just the worst adobe bricks, and you can build a pottery kiln with adobe bricks.

It's not just a pottery kiln, think about the cave where the snake tribe lives now, the area inside is so large, except for the position occupied by Wu, Derpy, the leader, and Su Yan, the sleeping places of the other clansmen are very small, almost all of them are crowded together.

If there is masonry, you can directly build a house with bricks and stones, even in winter, it can resist the cold to a certain extent, and then add a clay kang to the room, then there is no need to be afraid of the cold winter.

Quack!

A crisp sound interrupted Su Yan's train of thought, and the sound came from the fire, more precisely from the pottery embryo in the fire.

Under the firing of the flame, the essence of the pottery embryo is changing rapidly, but the temperature of the flame cannot be controlled, and the quality of the pottery embryo is uneven.

Quack! Quack!

Just as Su Yan thought, after that, several sounds of pottery shattering came out, and the first pottery embryo was directly shattered.

This is just the beginning, and the other pottery embryos also emit "Quack! Sound.

After more than an hour, Su Yan prevented the tribesmen from adding firewood and grass to the fire, there was no longer any need for complete pottery in the two fires, and the sixteen pottery embryos had been shattered.

When it was getting dark, Su Yan used a wooden stick to pull a few times in the two ash piles, and several pieces of pottery were pulled out, and Su Yan picked up a piece of almost black pottery shards to observe carefully.

This casual can be called pottery casual, but it has no use, only intact pottery is useful, and what is the use of such a pottery fragment.

No, it can't be said that it is useless, the Xiaohua Xiaoyue sisters beside Su Yan like this pottery fragment with a shiny surface, and the other children's eyes are also shining when they look at the pottery fragment.

Su Yan didn't care about handing the pottery fragments in his hand to Xiao Yue, and then asked Xiao Yue Xiaohua to go to the ashes pile to find the pottery fragments by herself, at this time there was no heat in the ash pile, but the black ashes were very dirty on her body, so Su Yan used a wooden stick to pull it.

Sister Xiaohua Xiaoyue happily squatted on the ash pile to find pottery shards, and the other children ran over to join the army in searching for pottery shards after seeing Xiaohua Xiaoyue's movements.

Su Yan glanced at the children playing in the ashes, shook his head, turned around and left to find a place to sit, thinking and waiting for dinner.

Today's failure in the first attempt to make pottery did not make Su Yan depressed, don't they all say that "failure is the mother of success", you can also accumulate experience when you fail, and you can succeed in the end if you fail more times.

What's more, now Su Yan thought of bricks and stones that are more important than pottery, making adobe bricks is simpler than firing pottery, and it is easy to make them on a large scale, building houses with adobe bricks can live in people, and building a wall with adobe bricks can block wild beasts.

Masonry is no less useful than pottery.

Su Yan decided to postpone the firing of pottery, and was ready to start making bricks and stones, first building walls, then building houses, and finally building pottery kilns to burn pottery, just because many clansmen had more free time when the fish cage appeared, and now Su Yan wanted to find something to do for them.
