Chapter 368: Lime
"Bang dang!" The charcoal was knocked out, much better than expected, although there were still large sticks that didn't burn through in the middle, but it was only a minor problem. Pen % fun % Pavilion www.biquge.info
The burned charcoal is stored in a dry place for later use, and this is certainly not enough, and it needs to be continuously stored. Because he didn't know exactly how much charcoal he needed.
Maybe one day he will think of planting trees, but not now, after teaching some people how to burn charcoal, he will withdraw first.
Two days later, people from the three tribal alliances sent food one after another, and sure enough, they were all defective, such as wild vegetables that had just emerged, sour fruits, and even grass roots and some edible leaves.
There is really not much to eat in this season, except for these, there is also meat, but it is either very thin or with a lot of bones.
He said that as long as the things he brought were filled with a small clay pot, he could come to pick up the clay pot when the moon was full, not a pure fool, but whether the clay pot was not fired and could be exchanged for spot in the future.
Fortunately, he has never had a bad record, and outsiders are willing to believe that there is no way, and the day when the business reputation will always pay off.
However, the real situation is that the three major tribes can't afford to provoke them, and they can only admit to being deceived, and they break their teeth and swallow them in their stomachs.
The problem of charcoal is solved, and the wood is also constantly in storage, and the branches and other branches that have been cut down can also be used.
The stones are also easy to get, the clansmen are moving stones on Xiyi Mountain, and the ones without color are used as ordinary stones, and the colored ones are stacked separately, waiting for Su Yang's next step.
In addition, food is also needed in the early stage, in addition to the Kasa to find a way to send some, the base camp has the Xiong clan is also carrying out material support, and the salt mine has been activated again, at least the team is not short of salt.
He also appropriately arranged for people to hunt, and his life could always go on, not asking for good, but for food.
Tin ore is constantly collected, although it accounts for a small proportion of copper ore, but it is indispensable. The other is the secrecy work, bronzes are epoch-making products, related to the rise and fall of the tribe, but the smelting process is complicated, and there is no need to worry about leaking out in a short time.
According to his requirements, the clay pot has more patterns, mainly used to cooperate with smelting.
At this time, he is working on a blower, which must be used, if it is just a small stove, it is okay to make a hole in the copper pot, and it is okay to use a fan, but for the furnace, to maintain the temperature continuously, reaching thousands of degrees to melt the copper, it needs air support.
So the blower is indispensable, only he can do it, he has been testing for a day, and it has not been successful for the time being.
In addition to this, the modeling also needs to keep up, there are only two methods, either use the existing materials, pottery, wood, bamboo, bone, stone, etc., and after a little processing, it becomes a mold. And then there are more creative, modeling with clay, pouring, this is a bit more troublesome.
Because the mold is often reversed, such as movable type printing, the model of the word is inverse to the normal word.
It's like looking in the mirror, obviously the hair is to the left, and the mirror is to the right, and he still has a little experience, if the mold is wrong, it will be smashed and restarted.
Slow work and meticulous work, not in a hurry, waiting for him to make a standard mold, in the selection of smart people to learn, mass manufacturing.
At this time, he suddenly thought about whether to make some copper coins, and forget about the copper coins, this is too Qing Dynasty. Can you get some knife coins or something, or have his head printed on copper dollars?
If later generations of archaeology found copper coins in this period, and found the head on it, they would definitely exclaim, the one who sold cakes had the emperor in the primordial.
After wiping his saliva, let's smelt the red copper first, and when the time comes, there will be slag, clay, and limestone, and this recipe is actually cement.
Shaking his head, he didn't think about the cement for a while, and then he spent several days modeling it, just coming up with some simple structures, such as the tools needed today, axes, scimitars, chisels, hammers.
Axes and scimitars are used for cutting, chisels and hammers are used for quarrying stone, and hoes and other things are too expensive to consider for the time being. The next step is to first meet the military weapons, and then to meet the agricultural tools, which is more economical than the spearhead.
Of course, some such as pliers, piers, etc., are also needed for hammering weapons. Thinking of these, I always feel that the picture is too beautiful and is about to be developed.
Where there is input, there is output, and rows of sheds are built here, without walls, but with watchtowers, it is more like a village.
The first clay pots were made and placed under the wooden shed to dry in the shade, not in the sun, otherwise they would crack. With the current weather, it will take more than ten days to dry in the shade, which is almost enough to catch up with the full moon.
He invested fifty people to make pottery, ten per person a day, that is, five hundred pottery, in half, plus scrapping, how can there be one or two hundred, almost enough.
In addition to the clay pots, there are also some special tools, such as water diversion pipes, which are completely fired with pottery and used to drain copper water, and the rest of the things cannot withstand the heat. Pottery is a good thing, thousands of degrees without pressure, no deformation, no cracking.
Everyone has something to do, and the progress of finding ore is not slow, mainly in the early stage, a lot of stones can be picked up, and a lot of the surface of the mountain can be dug out, but the more you go to the back, the more difficult it is, and you need better tools to support it.
After a few days like this, I didn't expect Spring to come back so soon, with about two hundred people, all carrying limestone on their backs.
Although the stones are very heavy, the average person can't carry much, but it is completely enough to cope with the early stage.
"Smash, smash as many of these rocks as you can."
It's not that the stone can't be burned if it's too big, but it's a waste of time.
He spent some time in a cement factory in the present era, just because the cement produced by that factory was an old variety of slag and gangue cement, and it still used a vertical kiln, and there was no cooler, so it was on the verge of bankruptcy. Then the boss switched to pig farming, which was also a tragedy.
Burning cement is nothing more than two grinding and one burning, at the beginning is to crush the mined limestone with a machine, and after burning, it is manually transported out to cool and grind.
At this time, of course, there is no need to be so troublesome, just try to smash a little, too small is not good.
The temperature of calcined limestone is 800 and it can be operated, and if there is coal, even ordinary coal can be burned, which is not complicated.
The calcination process and time are related to the temperature, the temperature is about 900, and the limestone with a diameter of three centimeters can be burned through in one hour; The temperature is about 1,000, and it can burn through 6 centimeters, reaching more than 1,000 and 1,000 centimeters, and burning through more than 10 centimeters.
Of course, this is a theoretical value, in fact, because the thermal conductivity of lime is less than that of limestone, that is, when the outside is burned into lime, the remaining stone inside will be more difficult to calcin, so if the diameter of limestone is more than 15 cm, the calcination time will be more than one day.
Of course, if it can be solved with a rotary kiln in modern times, saving several times the time, the principle is to preheat in advance, and the temperature is used in the pipeline back and forth, and there is basically no pollution, but now in the primitive period, it is not easy to burn lime with a vertical kiln.
