The pottery basin was tilted, and the clarified water inside flowed along the edge of the basin into another basin, leaving behind the plant ash that had completely turned into mud.
Han Cheng added water to it again, stirred it until it was clear, and then poured the water into another basin.
This water will not be thrown away directly, but will be retained for tanning. It is best if it can be recycled.
After doing this three times, it stopped.
He took out the plant ash that had been completely soaked in water in the basin and divided it into two parts.
The newly soaked plant ash is soft and does not stick together at all. Don't worry too much about this. The same is true when the cement white ash has just been mixed. Once it dries, it will become extremely strong.
He found several wooden sticks with a diameter of three to four centimeters and pieced them together into an irregular rectangular frame. The outside was pressed with stones, which could prevent the wooden sticks from rolling randomly and destroying Han Cheng's designed shape.
After the simple mold was made, Han Chenggong poured some of the plant ash that had been soaked in water several times into it and tried to flatten it with his hands.
After standing here and watching for a while, he washed his hands and told Wu not to let anyone touch them. Then he picked up the small basket he always carried, followed by General Fu, and headed outside the courtyard wall.
If Han Cheng's hair was styled into two braids, his little leather skirt was made less sexy, and he hummed "Mushroom sauce, it tastes so fragrant...", he would be like a little girl picking mushrooms...
However, he is not going to pick mushrooms, but to get some sand back and prepare to mix sand into the remaining plant ash, just like the cement in later generations. Compare the two to see which one is stronger.
Logically speaking, the one mixed with sand should be stronger, but after all, this thing is plant ash, not cement.
He had never come across the use of plant ash as an adhesive before. It was very necessary to conduct certain experiments to verify the results. Otherwise, he would not find anything wrong until the roof was pasted.
But there is some trouble.
The place with sand is a bit far away from the tribe, at a bend downstream of the river, almost two miles away.
When Han Cheng walked out, he happened to meet his senior brother and Shang, each carrying a load of dung walking past the door, so he stopped them.
Let them put their burdens aside first, pick up their weapons and accompany him downstream, just to rest.
Because of the existence of this large group of people, there are generally no large beasts around the Qingque tribe.
When these monkeys that walk upright and wield sticks gather together to survive, the overlords in the wild will generally not easily provoke them.
But this is not certain. After all, animals all have legs and can run. Although generally large beasts have their own fixed hunting territories and will not wander around easily, there are also some who have their territories robbed or who love freedom uninhibitedly.
The ancient overlord likes to be a wandering bard.
If an unlucky man encounters him, not to mention swallowing him whole, but just raising his huge paw to hit him with a monkey stealing peach, Han Cheng feels that not only can he be a eunuch, but he can also play this book.
over……
The sand in the river bend downstream is not particularly fine. This may be related to the fact that the Qingque tribe now lives close to the source of the river, and the sand in the river has not been washed by enough large waves.
A basket full of sand was carried in the hands of the senior brother. Han Cheng was carrying a very strenuous piece of sand, but he couldn't tell how much weight it weighed in the senior brother's hands. Han Cheng shook his head and said to himself, it seems that he will have to eat more, sleep more and exercise more in the future.
, grow taller as quickly as possible and have great strength, so that you can do more things and not be overwhelmed...
The sand at the inlet 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 unwilling 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 plant ash.
You can't mix too much sand, and you have to pay attention to the right amount in everything. It's better if the sand is mixed so that the true color doesn't leak out.
Of course, this is only a rough standard, and more detailed standards will be divided according to different uses in subsequent practice.
The mixed, extremely unique cement was put into a simple mold by Han Cheng as before, waiting to dry and solidify.
Senior Brother and Shang, who were standing aside to watch the excitement, couldn't help but look at each other in confusion, obviously not understanding the Son of God's intentions.
Han Cheng smiled and said to them that they would know the result after waiting.
The two of them stopped asking any more questions and went back to their work of picking dung.
Han Cheng took a look and saw that there was no water stain on the surface of the pure grass ash 'spindle' that he had placed previously, so he broke off a small grass stem, poked it a little, and found that it was still very soft, so he used it before
The clay pot was cleaned to prevent it from drying on it over time and making it difficult to clean.
The two cement 'spindles' are placed out of direct sunlight to avoid high temperatures 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 longer. Seeing that the results could not be seen in a short time, he took Fu Jiang back to the autumn wilderness.
Fu Jiang must be taken out. No one will touch the things that Han Cheng has instructed no one to touch, except Fu Jiang, this lawless silly dog...
Outside the courtyard, the people of the Qingque tribe are still busy. If they want to wear the crown, they must bear its weight. If they want to enjoy more superior living conditions, they must work hard for it.
The sun is setting in the west, and twilight is slowly covering the sky like a big net.
The tired birds returned to the forest, and the people of the Qingque tribe, who had worked hard all day, also took their tools and rushed into the courtyard in the dusk. They stopped working and enjoyed this rare moment of leisure...
Smoke rises from the cooking pots, and the aroma of rice mixed with the dusk fills the tribe, making people feel extremely at ease...
Han Cheng didn't need to speak, there was a talkative little kid standing by the two slightly solidified cement ingots. When he saw someone passing by, he would say something to make people pay attention not to step on the things made by the Son of God. Small review
Same machine.
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. Generally, no one would go there.
After they shouted like this, the people who came back came over to see the strange things. The children shouted even more happily when they saw the adults coming.
Dusk gradually fell, the light was dim, and the true appearance of the thing surrounded by wood could not be seen clearly, but the people who came to watch still looked at it carefully for a while, and then left with some expectation and satisfaction...
