Chapter 39 The First Iron Tool

The fire burned all day and all night.

After the temperature of the burrow dropped, several men jumped down and brought up pieces of pottery.

The quality of this batch of pottery is very good, even better than the pottery of the Taotang tribe, only a few are damaged, and the rest are high-quality pottery. It can be seen that the craftsmanship of the tribe is not bad, it is just a technical problem of firing, Li Yan Solved the problem of temperature, making tribal pottery a qualitative leap.

Li Yan held the two pieces of pottery he made and returned to the tribe full of joy.

After that, he dug some earth to make pottery.

After the two pieces of pottery were assembled, Li Yan turned them with one hand and supported the clay with the other. It didn't take long for a pottery bowl to be completed in two-thirds, and the efficiency was quite fast.

The pottery women onlookers all stared wide-eyed. Now they finally know how to use the pottery tool made by Li Yan. There is no doubt that with this tool, the tribal pottery can be produced in large quantities. In addition to that kiln, Taka The pottery level of the tribe can catch up with the Taotang tribe.

"This is called a potter's wheel. You should use this tool to make pottery in the future." Li Yan said to them.

"Uh-huh."

"Let's try."

Mu and several women hurried over to study the pottery wheel made by Li Yan.

"Mum, where did you get your red powder?"

"Chifen is ground from Chishi, and it's in Xishan."

"Uh-huh."

Li Yan washed his hands clean, and sent a few men to Xishan to fetch red stones.

Xishan is where the waterfall is, and there is a place with many stones.

Li Yan and the others came to rummage in a stone pile in Xishan, and they found many red stones.

So they collected several baskets of stones and returned to the tribe.

He asked Wingo to help break the iron ore.

Then he went to the place where pottery was made and made a crucible. This time the crucible he made was not made of clay, but ordinary red clay. There is a lot of red clay at the foot of the mountain. This kind of red clay is more delicate and does not have many impurities. And gravel, so that glaze will not form at high temperature and pollute the molten iron.

A few days later, the tribe's second batch of pottery came out, including this crucible made by Li Yan. Besides the crucible, there were also many clay bricks and a knife mold.

He found a few more men, built a furnace with these earthen bricks, and sealed the gaps with mud.

After the iron ore powder was crushed, Li Yan put the iron powder into the crucible.

However, ironmaking requires high-temperature fuel.

Charcoal is by far the most readily available material.

So he took people to cut some trees and came back.

Making charcoal is very simple, just burn it in an oxygen-deficient space, and it will be suffocated.

So he piled the logs on the ground, put some branches and dry grass on the surface of the logs, and then wrapped the outer layer with a layer of mud.

When the mud was a little dry, he lit a fire in several openings under the pile of mud.

These openings are then slowly closed, thus completing a sealed high-temperature condition.

On the second day, Li Yan came back again and knocked open the pile of mud.

Sure enough, there were pieces of charcoal in it.

Gather those chunks of charcoal and bring them back to the ironworks.

Now that you have charcoal and a stove, you need a blower.

He also fashioned several pipes leading to the iron furnace out of clay, and a flat container fired in pottery, which was connected to the pottery pipe, with a smaller opening on the top, and a fan wing made of bark and branches. , the fan wing is connected to a wooden stick, assemble the fan wing into a pottery container, find a bow and wrap it around the wooden stick, and pull the bow to turn the fan wing to generate wind.

At this time, Wen Ge and several men were watching expectantly, and even Mu and Black and White Witch came to watch.

"You watched."

"Ge, I'm going to teach you the technology of making iron."

Li Yan is full of confidence in this iron smelting.

Soon, all the tribesmen came to watch.

Put iron ore powder and charcoal powder in the crucible.

Put the charcoal and this crucible in the furnace, light the charcoal in the lower opening of the furnace, and turn the clay blower.

call!
call!call!
The blower whirred, adding oxygen to the furnace, and the charcoal blazed.

The temperature of the furnace was a bit high, and Li Yan kept wiping off his sweat.

His hand became numb when he drew the bow, so Li Yan asked Wen Ge to do it for him.

As the temperature continued to rise, the iron ore powder and charcoal in the crucible began to react, and some red water slowly precipitated.

"almost."

"Let's work harder."

The more Li Yan looked at it, the more excited he became. The crimson water is molten iron. This crucible is not only convenient for iron smelting, but also can reduce impurities, which is much better than the ancient block iron smelting.

time flies.

The iron ore powder in the crucible gradually turned into molten iron, but there was not enough charcoal powder in the middle, so Li Yan added some more to it.

almost.

Li Yan found two flat stones, clamped the crucible, and carefully poured the molten iron in the crucible into the knife mold.

When the molten iron was poured into the mold, some smoke rose, which was very powerful.

The crucible just filled the mold.

Now everyone still doesn't know how to use this water thing.

After an hour, the molten iron in this mold slowly hardened.

But still hot.

So, Li Yan put the mold in a water tank.

times~~~
A white mist rose up, like a god descending from the earth.

This is called quenching, which can form martensite on the surface of the iron and increase the hardness of the surface of the iron.

After a while, Li Yan directly reached into the water tank to fish out the mold.

Then go back to the hearth and break the mould.

Gradually, a somewhat dark object appeared.

This is a blade about forty centimeters long.

"Wingo, here you are."

Li Yan handed the blade to Wen Ge.

"This is iron. It is made of red stone. This thing is harder than stone and can be shaped into various shapes. It can be used to make iron picks, shovels, and even weapons. It must be more powerful than stone tools."

While listening, Wen Ge stared at the iron blade in his hand with bright eyes.

I saw Wen Ge squatting down again, grinding the blade of the iron blade against the stone. His professional habits, he wanted to sharpen any hard things he saw.

Wengo was right, though.

Wen Ge was indeed a craftsman, and he saw at a glance that the iron knife still needed to be sharpened.

Li Yan was very satisfied, and said again: "Ge, this is called an iron knife, it becomes sharper as it is sharpened, even sharper than a stone tool, and it needs to be wrapped with animal skin or wood around its handle."

"Uh-huh."

Wen Ge touched the iron knife, and then lightly tested its sharpness with his thumb.

"Ha! Ha!" Wen Ge suddenly laughed happily, which shocked everyone present. Even Li Yan wondered if he was insane.

"Patriarch, this knife is a good thing. It is as powerful as a witch weapon. Patriarch, you can create this weapon that is more powerful than a witch weapon without using a witch stone. You are really amazing."

Wen Ge's eager gaze made Li Yan shudder.

Hearing this, the black witch hurried over and snatched the iron weapon.

"Wow! Wow! Wow!"

"This iron knife is very hard, as powerful as a witch knife. Ordinary people can kill Pangu warriors with this knife!"

"Witch stones are so precious, the patriarch can actually make a weapon as powerful as a witch weapon out of wood and stone!"

The black witch also lost his nerve, and kept praising the iron knife.

When the tribal men around heard this, they surrounded Hei Wu and Wen Ge one by one.
