The ceramic basin was tilted, and the clarified water inside flowed down the edge into another basin, leaving behind the wood ash that had completely turned into mud.
Han Cheng added clean water into it again, stirred it to clarify it, and then poured the water into another basin.
This water will not be poured away directly, but will be retained to make nitrate leather. It would be best if it can be recycled.
After doing this three times, it stopped.
He took out the wood ash in the basin that had already been completely soaked with water and divided it into two parts.
The wood ash just out of soaking is soft and cannot be lumped together at all. There is no need to worry too much about this. The same is true when cement and white lime are just mixed. Once it dries, it will become extremely solid.
He found several wooden sticks with a diameter of three or four centimeters and pieced them together into an irregular rectangular frame, which was pressed down with stones on the outside. This could prevent the sticks from rolling around and destroying the shape designed by Han Cheng.
After making the simple mold, Han Cheng poured some wood ash that had been rinsed with water several times into it and tried to flatten it with his hands.
He stood here and watched for a while, then washed his hands, told the witch not to let anyone touch these things, picked up the small basket he always carried, followed by Fu Jiang, and went outside the courtyard wall.
If Han Cheng's hair was braided into two pigtails, her leather skirt was a little less sexy, and she hummed a song like "Mushroom sauce, it smells so good...", she would be a perfect mushroom-picking girl...
However, he did not go to pick mushrooms. Instead, he wanted to get some sand and mix it into the remaining wood ash, just like cement in later generations. By comparing the two, he wanted to see which one was stronger.
Logically speaking, the material mixed with sand should be stronger, but this thing is wood ash after all, not cement.
He had never used wood ash as an adhesive before, so it was necessary to conduct some experiments to verify the results. Otherwise, it would be troublesome if he found something wrong after pasting it on the roof.
The sandy area is a bit far from the tribe, about two miles away at a bend in the downstream river.
When Han Cheng walked out, he happened to meet the eldest brother and Shang, who were walking past the door, each carrying a load of manure, and they stopped them.
Let them put their burdens aside, take up their weapons and accompany him downstream, just to take a rest.
Because of the presence of such a large group of people, there are generally no large wild beasts around the Qingque tribe.
When these monkeys that walk upright and wield sticks gather together to survive, the overlords of the ancient world generally do not easily provoke them.
But this is hard to say for sure. After all, animals have feet and can run. Although most large beasts have their own fixed hunting territories and will not wander around easily, there are also some unruly and freedom-loving overlords who like to be wandering bards.
If he were unlucky enough to encounter one, not only would it swallow him whole, but it would also raise its huge claws to attack him like a monkey stealing peaches. Han Cheng felt that not only would he be a eunuch, but even this book would probably be finished...
The sand in the downstream river bend is not particularly fine. This may be related to the fact that the place where the Qingque tribe currently lives is closer to the source of the creek and the sand in the river has not been washed by enough waves.
The senior brother held a basket full of sand in his hand. Han Cheng was carrying the sand with great effort. He could not tell how heavy it was in the senior brother's hand. Han Cheng shook his head and thought to himself that he should eat more, sleep more, and exercise more in the future. He should grow taller as soon as possible and have great strength. Only in this way can he do more things and not be overwhelmed...
The sand in the bay is washed very clean by water. This kind of sand is the best and will not affect the firmness of the cement.
After the eldest brother and Shang escorted the Son of God back to get the sand, they were reluctant to leave immediately.
Han Cheng knew what they were thinking and did not urge them. Instead, he took some sand and mixed it with the remaining wood ash.
Don’t add too much sand. Everything should be done in moderation. It is best to add sand so that the original color does not show through.
Of course, this is just a rough standard. More detailed standards will need to be divided according to different uses in subsequent practice.
Han Cheng put the mixed, extremely unique cement into a simple mold in the same way as before, waiting for it to dry and solidify.
The eldest brother and Shang, who were standing aside watching the fun, couldn't help but look at each other in confusion, obviously not understanding the Son of God's intention.
Han Cheng smiled and said to them, we will know the result after waiting.
The two of them didn't ask any more questions and went back to their job of carrying manure.
Han Cheng took a look and saw that there was no water stain on the surface of the 'ingot' of pure wood ash that had been placed there before, so he broke off a thin grass stem, poked it slightly, and found that it was still very soft, so he cleaned the clay basin that had been used to mix the mud before, in order to prevent it from drying up and being difficult to clean.
The two cement 'ingots' are located out of direct sunlight to prevent high temperatures from affecting solidification.
What needs to be done has been done, and the rest can only be left to the magical catalyst of time, waiting for the results it brings, whether good or bad.
Han Cheng stayed here for a while, and seeing that it would not be possible to see results in a short time, he took Fu Jiang and went back to the autumn wilderness.
Fu Jiang must be taken out. No one will touch the things that Han Cheng has ordered not to be touched, except for Fu Jiang, the lawless fool...
Outside the courtyard, the people of the Green Bird tribe are still busy. If you want to wear the crown, you must bear its weight. If you want to enjoy better living conditions, you must work hard for it.
The sun sets and dusk slowly descends like a huge net.
Tired birds return to the forest, and the people of the Qingque tribe, who have worked all day, also rush to the courtyard with their tools in the twilight. They stop working and enjoy this rare moment of leisure...
Smoke from cooking rises, and the aroma of rice mixed with the twilight fills the tribe, making people feel extremely at ease...
Han Cheng didn't need to say anything, as there were talkative little children guarding the two slightly solidified cement ingots. When they saw someone passing by, they would tell people to be careful and not step on the things made by the Son of God, like little tape recorders.
In fact, the place where Han Cheng placed the two cement ingots was five or six meters away from the main road in front of the cave, and generally no one would go there.
After they shouted like this, the people who had returned came closer to see what was happening, and the children shouted even more excitedly when they saw the adults coming.
As dusk gradually fell, the light dimmed and it was impossible to see the true appearance of the object surrounded by wood. However, the people who came to watch still looked at it carefully for a while, and then left with some expectation and satisfaction...
