Chapter 332 Small Iron Beads

In the courtyard of the Qingque Tribe, Hei Wa was digging a hole in an empty space.

Han Cheng used the soil dug out by Heiwa to water and mud.

They are going to rebuild a kiln or an iron furnace here.

The earthen kiln beside the small river outside the Qingque Tribe is fine for firing pottery and tiles, but it is too big for putting charcoal and iron.

Digging soil and mud, building vents... These things were done very smoothly, and within half a day, a brand new small stove came out.

There is a flame burning inside the stove, and the ventilation effect is very good.

It has to be said that Heiwa's technology in building these things is getting better and better.

Han Cheng went to the stone slab and picked up some mud lumps to see, but they were only half dry.

After thinking about it, I took out a dozen or so and put them on the edge of the stove to roast them with fire, so that they would dry quickly and the experiment could be carried out as soon as possible.

After a while, see that the mud bumps are almost dry, and put the charcoal that was burned before into the stove.

On top of the charcoal there are four lumps of mud.

The iron smelting experiment had just begun, and Han Chengcheng discovered the problem.

The charcoal fire of the stove is not burning strong enough.

The solution is to get a small blower or bellows out.

Han Cheng is no stranger to the blower. When the weather turned cold when he was a child, people who fried popcorn would come from the village one after another during the slack season.

Set up a simple stove with a fire inside, and put something that looks like a bomb on it, burnt black.

It contains corn or rice.

After burning on the fire for a while, the 'bomb' was removed from the fire, put one end into a long pocket, kicked hard, and after a loud explosion, hot popcorn was born...

Han Cheng's favorite thing to do at that time was not picking up the popcorn that was thrown to the ground with other playmates, but squatting next to the stove and shaking the blower, also known as Fenggulu.

The structure of this thing is relatively simple, the main thing is to collect the wind generated by the rotation of the fan leaves inside through the narrow air outlet, and blow it into the stove.

People who see hope are full of energy.

Complicated Fenggulu Han Cheng can't make it, and there is no problem with simplicity.

If there is no iron sheet to make the outer shell, the model is made of clay, and after drying, it is fired into pottery.

There are no iron rods for shafts or iron sheets for fan blades, so wooden sticks and bark are used instead.

Carve a cross on one end of a wooden stick with a stone knife, and cross two pieces of bark ten centimeters long and four centimeters wide.

A gap of two centimeters is carved at each intersection, and they are stuck together, and then stuffed into the tree stick of the cross.

Tie it up with a thin rope, so that a rotating shaft with fan blades is ready.

Put it in the shell made of pottery, put a stone with a small hole under it, and rub it with your hands, and the wind will come out of the seal.

Put a pre-made clay pot on the air outlet, and insert the other end into the air inlet of the stove. When you rub it hard, the wind will flow into the stove along the pottery tube, and the fire in the stove will become much stronger immediately.

Heiwa's eyes lit up immediately.

After rubbing like this for a while, his hand hurts. Han Chengcheng found a hand press drill, removed the drill pipe, put the shaft with fan leaves in it, and pressed it back and forth a few times, and it seemed easy.

There is one thing that needs to be said, the general Feng Gulu is placed vertically, but the one made by Han Cheng is placed flat, so that the hand press drill can be used to fan the flames.

"Whirring whirring……"

Heiwa pressed his hand to press the drill, and looked at the flames in the furnace that fluctuated with his movements, his eyes were bright.

It was very similar to when Han Cheng squatted beside the fried popcorn and shook the wind.

With Feng Gulu, it will be much faster to burn these iron-containing mud lumps.

After half an hour, the iron bacteria pimples placed in the stove turned red.

It burned for a while, showing signs of melting and softening.

Seeing that the heat was almost ready, Han Cheng used two long wooden sticks to clamp it out of the stove.

Put it on a stone that had been prepared a long time ago, put out the fire on the two sticks that were on fire, and picked up another large stick to strike while the iron was hot.

"Bang bang bang!"

With his beating, the red slag disappeared in a flash and rolled to the side.

It didn't take long for the group of iron bacteria to turn from red to black.

Han Cheng beat for a while and saw that he couldn't move, so he stopped.

At this time, even half of the previous iron bacteria was gone.

After throwing it into a pottery pot aside and soaking it in water, I picked it up, held it in my hand and looked carefully, and found that this irregular piece was far from the iron.

After thinking for a while, Han Cheng found a stone and smashed open the piece of iron, which was not considered a semi-finished product. After watching it carefully for a while, Han Cheng found the figure of the small iron bead inside.

Looking at the eight small iron beads in his hand, the largest of which was no larger than mung beans, Han Cheng couldn't help smiling.

Iron!

This is iron!

It has been four years since I came to this era, and now I finally saw traces of metal, how could Han Cheng not be excited, how could he not be excited?

Hei Wa on the side looked at Han Cheng who was grinning behind his ears, and then at the small bumps in Han Cheng's hands. He really couldn't figure it out. so happy?

Can this thing make tools that are harder and more durable than stone?

But he soon laughed too, it wasn't that he figured things out, but that he was having fun with Shenzi.

"Burn! Continue to burn!"

Han Cheng cherished the small iron beads in his hand and put them into a clay pot. He yelled excitedly like chicken blood, and put more than a dozen mud bumps into the stove at once...

Starting from this day, the newly built furnace in the Qingque Tribe burned for five consecutive days before finally stopping temporarily.

"Clatter..."

"Clatter..."

Han Cheng hugged the not too big but heavy jar, shaking it from time to time, with an idiotic smile on his face.

This side is filled with large and small iron beads. This is the result of continuous labor in the past few days, and it weighs about two catties.

This is the scale accumulated after the iron bacteria near the Qingque tribe were scoured.

With these iron beads, he became more confident in the following matters.

With the high-purity iron beads, the next thing to do is to heat and melt these iron beads to make a block of iron.

After much deliberation, Han Chengsi decided to put a layer of charcoal in the stove first, then put the iron beads into four pottery bowls of different sizes and put them on the layer of charcoal.

Then add a thick layer of carbon on top and start to ignite.

This crude method and tool consumes a lot of charcoal and time.

But now is obviously not the time to think about these things. It is already thankful to be able to get the iron out. How can there be any time to consider the loss?
