The production of salt was basically done by Han Cheng and the children of the tribe as well as the sick and disabled women and children.
The most powerful generals in the tribe, the senior brother and others, did not participate much, because just going out to hunt and obtain enough food for the tribe had already spent almost all their energy.
All they could do was take advantage of some rare free time to transport rock salt from the salt mountain to the river.
This makes Han Cheng quite helpless. The food problem is always a knife hanging over his head. If the food problem can be solved, the productivity of the tribe will be greatly liberated, and more people can be produced.
Use your energy to do other things.
But, how easy is this thing?
Han Cheng's motherland in his previous life was strong enough and had a long enough history. It was only in the past twenty or thirty years that the people were truly free from the fear of hunger...
Fortunately, the consumption of salt was not too large. As they became more familiar with the salt-making process, Han Cheng and the others were able to produce about ten kilograms of salt every day. These ten kilograms of salt were almost enough for the tribe to use for a month.
After the tribe's salt storage amounted to five jars exceeding one hundred kilograms, Han Cheng was no longer as hasty as before.
Instead, the amount of salt produced every day was reduced by nearly half.
On the way to making salt, they fired pottery from two kilns again, mainly casting pottery basins and pots that were needed for making salt.
When the pottery in the tribe was enough, under the initiative of Han Cheng, it was decided to reform the pottery making technology.
The focus of the reform was not the method of making pottery, but the kiln in which the pottery was fired.
The advantage of using this simple clay kiln is that it is more convenient to build and easy to master. The disadvantage is that it is too troublesome and requires re-pasting every time pottery is fired.
It is not as convenient as using a kiln built with bricks.
Of course, a kiln built with bricks was very troublesome at the beginning, especially building a kiln. Han Cheng only knew a rough idea about this.
In addition to overcoming the difficulties of digging cellars, making bricks, and designing shapes, we also need to explore the control of fire and other things bit by bit and sum up experience.
But it doesn’t matter. Which technology development has not gone through such steps?
If we are afraid of this trouble and that trouble, then the world will stop moving forward.
The Qingque tribe can only use simple clay kilns in the future, and their pottery-making technology has stopped here.
Don't stop eating because of choking.
They can't make bricks now, not only because they don't have a kiln for burning bricks, but also because they don't have enough fuel.
Baking bricks takes too long. If you rely on firewood alone to bake the bricks, it will take at least four or five days to bake the bricks and make them strong, even if there is a brick kiln.
If it is Shaoqing bricks, a large amount of water needs to be poured from the top of the kiln, and it will take almost two days to turn off the water filling.
Four or five days of non-stop burning, not to mention manpower and material resources, just the firewood burned is a huge burden for the Qingque tribe with low productivity.
Burning bricks at this stage is really not worth the gain.
Of course, pottery is different from firing bricks, because the kilns used to bake pottery are relatively small, and the temperatures required are far less high than firing bricks, and the pottery is thinner, so it consumes much less fuel.
Han Cheng couldn't help himself without bricks. He could still build the kiln without bricks.
It's not that he has any superpowers, but that he can use a substitute for bricks - brick embryos.
Brick embryos are relatively easy to make, that is, mix mud, then put the mixed mud into a mud mold and press it into a rectangular parallelepiped, and then dry it in the shade.
Bricks of later generations were generally five thick, ten wide, and twenty long. Such specifications now obviously do not meet Han Cheng's requirements.
So he multiplied the length, width and height of the brick by two.
As for the earth pit needed to build the kiln, it can only be dug slowly with simple tools.
Fortunately, there was no rush to build a kiln and make pottery. They had enough time to do it. After all, pottery was not a one-time consumable, and they also had a simple clay kiln to support it.
However, he is not in a hurry about this matter, but Hei Wa is very anxious. After all, he is now the number one pottery maker in the Qingque tribe.
(Of course, except for the Son of God, because the Son of God has many fantastic ideas, but his hands-on ability is not good)
Heiwa gained his confidence from this. Because he felt a sense of accomplishment from making it, he became more and more fond of pottery making. After hearing Han Cheng say that there was a better way to make pottery, he couldn't sit still.
.
He is the most energetic person when it comes to digging pits and making adobe bricks.
According to the rules of the tribe, Hei Wa is now an adult. If it were before, he would have to go hunting with his senior brother and the others every day.
But things are different now. The appearance of salt and pottery has made the senior brother realize the importance of these things to the tribe.
And Hei Wa was a good pottery maker, so he didn't let him go hunting much, but concentrated on making pottery and boiling salt.
In the process of doing this, Han Cheng did not miss the rapeseed. As early as more than ten days ago, he led his people to suspend the production of salt and transported the mature rapeseed back in half.
During this process, Han Cheng specifically told them to be careful and never touch the rapeseed pods too often.
Han Cheng did not wait until the rapeseed was completely dry before harvesting it, otherwise he would not be able to collect it. Instead, he harvested it while there was dew. Even if he touched the rapeseed pod, he would not be able to throw away much.
The recovered rapeseed was placed in a small open space not far from the entrance of the tribe to dry.
This open space was opened a few days ago under Han Cheng's instruction.
In addition to removing the weeds and saplings above, Han Cheng also asked people to take advantage of the wetness to smash the area of about 11 to 12 square meters with flat stones.
Go over and smash the soil firmly, and smash all the small stone particles on the soil into the soil.
In this way, when the time comes to beat the rapeseed, there will be no floating soil and there will not be more small stones than the rapeseed.
Even though this area is only 11 or 2 square meters, Han Cheng and the others spent a lot of effort to get them out.
Due to the lack of tools, it took a lot of effort just to clean up the weeds, some small trees and bushes on it.
This is because there are no big trees in this small area. If there were big trees, they would just stare.
If you want to bring down a big tree, you can only rely on stone axes or bone axes, and everyone can go into battle and dig around for a whole day and night, but it will be impossible to do anything.
