The manufacture of salt is basically done by Han Cheng and the children in the tribe, as well as the sick and disabled women and children.

The most powerful senior brothers and others in the tribe did not participate much, because it had already taken almost all of their energy just to go out hunting and obtain enough food for the tribe.

All they could do was take advantage of some rare free time to transport the rock salt from the salt mountain to the river.

This made Han Cheng quite helpless, the problem of food is always a knife hanging over his head, if the food problem can be solved, the productivity in the tribe can be greatly liberated, and he can have more energy to do other things.

It's just that this matter is not easy to say?

Han Cheng's motherland in his previous life was strong enough and his history was long enough, and it was only in the last twenty or thirty years that he could really achieve that the people were free from hunger......

But fortunately, the consumption of salt is not too large, and with the maturity of the salt-making process, Han Cheng and the others can also refine about ten catties of salt every day, which is almost enough for the tribe to use for a month.

After the salt storage capacity in the tribe was more than one hundred catties in five jars, Han Cheng was not as tight as before.

Instead, the amount of salt produced per day has been reduced by almost half.

On the way to make salt, they also burned pottery from two kilns again, and the main casting was pottery pots and pots, which were needed to make salt.

When the pottery in the tribe was sufficient, under the initiative of Han Cheng, it was decided to reform the pottery-making technology.

The focus of the reform was not on the method of making pottery, but on the kiln in which the pottery was fired.

The advantage of using this simple clay kiln is that it is relatively convenient to build and easy to master, but there are also disadvantages, that is, it is too troublesome, and every time the pottery is burned, it needs to be re-pasted with mud.

It is not as convenient to use a kiln built with bricks.

Of course, the kiln built of bricks was very troublesome at the beginning, especially the kiln, and he only knew a rough idea of this Han Cheng.

In addition to overcoming the difficulties of digging cellars, making bricks, and designing shapes, it is necessary to explore and sum up experience little by little for the mastery of fire and others.

But it doesn't matter, which technology hasn't gone through such a step?

If you are afraid of this trouble, and if you are afraid of that trouble, then the world will stop.

In the future, their Qingque tribe could only use simple clay kilns, and the technology of pottery making came to an end.

You can't choke on food.

They can't make bricks now, not only because there is no kiln for burning bricks, but also because they don't have enough fuel.

It takes too long to burn bricks, and if you want to burn the bricks to be cooked and sintered, it will take at least four or five days to burn the bricks under the premise of having a brick kiln.

If there are few green bricks, a large amount of water needs to be poured from the top of the kiln, and it takes almost two days to turn off the irrigation.

Four or five days of uninterrupted burning, not to mention manpower and material resources, just the firewood burned, is a great burden for the Qingque tribe, which is not highly productive.

At this stage, it is really worth the loss to burn bricks.

Of course, pottery is different from brick-fired pottery, because the kilns used to fire pottery are smaller, and the temperature required is much lower than that of brick-fired pottery, and the pottery is thinner, so it consumes much less fuel.

Without bricks, it is difficult to resist Han Cheng, and without bricks, he can also build a kiln.

It's not that he has any superpowers, it's that he can use a substitute for bricks, brick embryos.

The brick embryo is still relatively easy to make, that is, and the mud, and then put the mud into the mud fan and press it into a cuboid, and dry the water in the shade.

The bricks of later generations are generally five thick, ten wide, and twenty long, and such specifications obviously do not meet Han Cheng's requirements now.

So he multiplied the length, width, and height of the brick embryo by two.

As for the soil pit needed to build the kiln, it can only be dug slowly with simple tools.

Fortunately, there is no hurry to build a kiln to burn pottery, they have enough time to do this, after all, pottery is not a one-time consumable, and they also have a simple clay kiln to top.

But he is not in a hurry about this matter, but Heiwa is very anxious, after all, he is now the first person to make pottery in the Qingque tribe.

(Of course, the Miko needs to be excepted, because the Miko has a lot of wonderful ideas, but the hands-on ability is not good)

Heiwa's self-confidence was picked up from this, because of the sense of accomplishment made on it, so she loved pottery more and more, and after hearing Han Cheng say that there was a better way to make pottery, she couldn't sit still.

Digging earth pits and making adobe is the most energetic.

According to the rules of the tribe, Heiwa is now an adult, and if it was before, he would need to follow the senior brother and them to participate in hunting every day.

But now it was different, the appearance of salt and pottery made the elder brother realize the importance of these things to the tribe.

And Heiwa is a good potter, so he didn't let him go hunting, but concentrated on making pottery and boiling salt.

As early as ten days ago, he led people to suspend the manufacture of salt and transported the ripe rape back from half off.

In this process, Han Cheng deliberately explained that he should pay attention to some things, and never touch the rapeseed pods all the time.

Han Cheng didn't wait until the rapeseed was completely dried before harvesting it, so he couldn't get it back, but took advantage of the dew to get it back, even if he touched the rapeseed pod, he couldn't throw much away.

The recovered rape was dried in a small clearing not far from the tribe's entrance.

This vacant land was carved out a few days ago at the behest of Han Cheng.

In addition to removing the weeds and small trees on it, Han Cheng also asked people to take advantage of the wet exhalation and use flat stones to smash the area of about eleven or twelve square meters with flat stones twice, smashing the soil firmly, and smashing the small stone particles on the soil into the soil.

In this way, when the time comes to beat rapeseed, there will be no floating soil, and there will be no situation where there are more small stones than rapeseed.

Don't look at this area that is only eleven or twelve square meters, in order to get them out, Han Cheng and they have made a lot of effort.

Because of the lack of tools, it took a lot of effort to clean up the weeds and some small trees and bushes on it.

It's because there are no big trees in this small area, and if there are big trees, they will only have to stare dryly.

If you want to bring down a big tree, you can only rely on stone axes and bone axes, and everyone will go into battle and chisel around it for a day and a night.
