I was a village chief in a primitive society

Chapter 308: Ironmaking. (2 more please customize)

"Make more."Su Bai said with a smile.

To produce iron, iron sand is indispensable. Of course, the more the better. There are not many that can be attached every time, so it takes a long time. As time goes by, every minute Three hours passed. There was already a lot of iron sand in the big wooden barrel they brought.

There was a whole barrel. Although it was black, it still glowed under the radiation of the sun.

"Wu, it's much better."Yanhua stood up and put the iron sand in her hand.

Niujiao Niang had sweated a lot on her forehead, but she didn't look tired.

"That should be enough, right?"Yu Ying is different. She looks very tired.

After all, she is not a warrior. She will inevitably have a little backache after bending down and getting up many times.

The fox-eared girl has been breathing heavily and reached out to wipe her hands. Sweat running down my forehead

"Hahaha......"Su Bai smiled when he saw the fox-eared girl,"That's enough, take a rest and then go back to the tribe."

He also bent down and absorbed a lot of iron sand. Since the system was improving every day, he didn't feel tired.

When Yuying heard that it was time to rest, she relaxed and quickly ran to the shore and sat down.

Yanhua and Shalan were still standing in the river. They felt that the flowing water was very cool and the feeling of passing over their feet was quite good.

After all, the sun is so bright in the sky, and the only way to cool down is to play in the water.

After everyone rested for half an hour, they washed their faces by the river and prepared to return to the tribe.

"Tap tap tap......"

Su Bai and others headed towards the tribe and returned to the tribe half an hour later.

"Wu, these things have been recovered, how can we make iron? Yanhua asked curiously.

She kept squatting in front of the barrel, reaching out to poke at the iron sand with a curious look on her face.

"Is it okay to just pinch these things together?"Shalan used the magnet in his hand to absorb the iron sand.

"You also need to prepare charcoal, it will be great if you have charcoal."Su Bai added

"carbon? This is very simple. There are many tribes, so I will go and get them."Yu Ying said immediately.

Yan Hua blinked her red eyes and asked curiously:"Witch, would it be better to have charcoal? So simple?"

"But what should we do after we have charcoal? With the iron sand sucked up from the river?"Sha Lan is also very curious.

"Well, just mix iron sand and charcoal at a ratio of 4:1 and heat it."Su Bai nodded lightly.

"So that’s it, then this is simple. Yanhua said.

Su Bai raised the corners of his mouth slightly and said,"This is not that simple. It is different from our firing of porcelain.""

"have difference? Aren’t they all put into the fire and burned? Yanhua scratched her head and said

"Because the maximum temperature for burning wood is only 700 degrees, but to turn iron sand into iron, the temperature must be as high as 150 degrees."Su Bai explained

"If this is the case, then the temperature is completely insufficient."Sha Lan put down the magnet in his hand.

"Heating is enough, as long as oxygen is continuously fed into the kiln, that is, air is fed in, so that the temperature can be increased to 1500 degrees."Su Bai said in a deep voice.

Yanhua nodded thoughtfully, clapped her hands and said,"Leave this to me, it's very simple."

"This is not easy. You will know in a moment. Let's start burning the fire in the kiln."Su Bai smiled.

After he asked people to light the fire in the kiln, he started to make a blower.

The original kiln had many small holes, and the blower made by Su Bai also had a small hole..

It just so happens that the small hole is aligned with the small hole in the kiln. As long as the blower is kept fanning, a steady stream of air will come in.

The production of the blower is also very simple. It is made with a piece of animal skin and two wooden sticks..The overall appearance is like a coin purse, with two wooden sticks tied to both sides of the opening, just like a bag, with a hole left on one side.

"Wu, the charcoal you want is ready."Yu Ying's cute voice sounded, and a lot of black charcoal was placed on the ground.

"Um."Su Bai began to put iron sand and charcoal in a porcelain basin at a ratio of four to one.

Then he put the porcelain basin into the kiln, and asked people to start adding firewood to it and start lighting the fire.

"crackling......"

The inside of the kiln began to burn, and the holes around the kiln were blocked by the blower.

Except for Su Bai, Yan Hua, Sha Lan and others all squatted in front of a blower and began to fan the blower desperately.

"Huhuhu......."

As the blower continued to fan, the flames in the kiln also began to grow.

In more than a minute, the flames in the kiln had turned red, but the girls were also tired.

The first one to fall down from exhaustion was the fox-eared girl. Her hands could no longer move and she collapsed completely on the ground.

The others could only hold on for five or six minutes at most. Their foreheads had already begun to sweat, but it was much better than the fox-eared girl. The fox-eared girl only lasted one minute.

"I said it’s not an easy thing, but I can’t stop."Su Bai smiled.

"Huhuhu......"

Yanhua gritted her teeth and continued to flap her arms, with a look of refusal to admit defeat, even if her hands were soft.

"Talk to others when you are tired, and keep the air flowing in continuously without stopping."Su Bai put his hand on the shoulder of the horned girl.

If he didn't say anything, the horned girl would keep competing with him until she was really tired and fell down.

The girls continued to fan for a minute, and then they couldn't do it anymore. , had to let others continue

"It's a chore, you have to keep changing people, otherwise you won't be able to get the temperature to 1500 degrees."Su Bai said

"Wu, how long is this going to last?"Yu Ying asked curiously

"It will take a long time, and it is a very arduous task."Su Bai said with a smile.

It takes dozens of hours to transport air into the kiln, so people need to be replaced frequently during the process. Otherwise, just one group of people will not be able to survive.

"Making iron is really not an easy task."Yu Ying kept swinging her wrists. She was so tired that she almost suffocated.

"Huhuhu......"

There was smoke coming out of the opening above the kiln, and the raging fire inside the kiln could be felt from the outside.

"It seems to be a long time coming."Su Bai turned his head and said,"Let's do something else while waiting."

"Wu, what do you want to make? Is it related to iron? Yanhua asked curiously.

When the Horn Girl first heard that Tie was going to be used to make a very powerful weapon, she had been in a state of excitement.

So when she was fanning the blower just now, the girl worked extra hard. It's the same even when iron sand is absorbed in the river..........................................
