Chapter 332: Small iron beads

In the courtyard of the Qingque tribe, in an empty space, the black baby is digging a hole.
Han Cheng used the soil dug up by Heiwa to water and mud.
They are going to rebuild a kiln or iron furnace here.
The earthen kiln beside the small river outside the Qingque tribe can be used to burn pottery and tiles, but it is too big to use charcoal fire to strike iron.
Digging the soil and mud, building up the vents... These things were done very smoothly. After half a day was not used up, a brand new small stove came out.
There is flame burning in the stove, and the ventilation effect is very good.
I have to say that Heiwa's technology for these things is getting better and better.
Han Cheng walked to the stone slab and picked up a few mud bumps, but they were only half dry.
After thinking about it, I took out a dozen of them and put them on the edge of the stove to bake them with fire, so that they dry quickly and can be tested as soon as possible.
After a while, to see if the sludge is almost dry, put the charcoal that was previously burned into the stove.
There are four mud bumps on top of the charcoal.
The iron smelting experiment had just begun, and Han Chengcheng found a problem.
The charcoal fire of the stove is not burning vigorously.
The solution is to get a small blower or a bellows.
Han Cheng is no stranger to the blower. When the weather turned cold when he was young, popcorn poppers would come to the village one after another during the slack.
Set up a simple stove, put a fire on it, and put something black that looks like a bomb or burned on it.
It contains corn or rice.
Burned on the fire for a while, the ‘bomb’ was taken off the fire, put one head into a long pocket, and kicked hard. After a blast, the hot popcorn was born...
Han Cheng's favorite thing to do at that time was not to pick up popcorn that was dropped to the ground with other playmates, but to squat by the stove and shake the blower, also called Feng Gulu.
The structure of this thing is relatively simple, the main thing is to collect the wind generated by the rotation of the inner fan leaves through the narrow air outlet, and then blow the inside of the furnace.
People who see hope are full of energy.
Complicated wind gurgling can't be produced by Han Cheng, and simplicity is not a problem.
If there is no iron sheet for the outer shell, the model is kneaded out of clay, and after it is baked and dried, the pottery is made by fire.
There are no iron rods for shafts, and no iron plates for fan blades, so sticks and bark are used instead.
Use a stone knife to carve a cross cut on one end of a wooden stick, and cross two pieces of bark ten centimeters long and four centimeters wide.
A two-centimeter gap was cut at each intersection and stuck to each other, and then stuffed into the cross sticks.
It is tied with a thin rope, so that a shaft with fan blades is completed.
Put it in the shell made of pottery, use a small pitted stone cushion underneath, rub it with your hands, and wind will come out along the seal.
Put a pre-made earthenware pot on the air outlet, insert the other end into the air inlet of the stove, rub it hard, and wind will flow into the stove along the pottery tube, and the fire in the stove will suddenly become a lot stronger.
Hei Wa's eyes lit up suddenly.
After rubbing for a while, his hands hurt. Han Cheng got a hand-pressed drill, removed the drill rod, installed the shaft with fan leaves, and pressed it back and forth a few times. It seemed relaxed.
There is one thing that needs to be mentioned. The general wind grunts are placed vertically, and the one made by Han Cheng is placed flat so that it can be used to fan the flames with a hand-pressed drill.
"Whirring whirring……"
Heiwa pressed her hand to press the drill, and her eyes were bright as she watched the flames in the furnace that followed his movements.
It was very similar to Han Cheng squatting beside the popcorn and screaming.
Burning these iron-bearing mud bumps can be much faster with the wind.
In half an hour, the lumps of iron bacteria in the stove turned red.
It burned for another while, showing signs of melting and softening.
Seeing that the fire is almost finished, Han Cheng used two long wooden sticks to clip it out of the stove and put it on a stone that had been prepared on the side to extinguish the fire on the two burning sticks. Pick up another large wooden stick and start to strike while the iron is hot.
"Boom boom!"
With his beating, the red scum flashed away and rolled to the side.
It didn't take long for this dumpling of iron bacteria to turn from red to black.
Han Cheng beat him for a while and saw that he couldn't move, and then he stopped.
At this time, this piece of iron bacteria is gone even half of what it was before.
After being soaked in the pottery basin, he picked it up, took it in his hand and took a closer look, and found that this irregular object was far from the iron.
After thinking about it, Han Cheng found a stone and smashed the piece of iron that was not a semi-finished product. After watching it carefully, Han Cheng found a small iron bead inside.
Looking at the eight small iron beads in his hand that were no bigger than mung beans, Han Cheng couldn't help smiling.
Iron!
This is iron!
It's been four years since I came to this era, and now I finally saw the traces of metal. How could Han Cheng not be excited, how could he not be excited?
The Heiwa on the side looked at Han Cheng, whose mouth was grinning behind her ears, and then at the little bumps in Han Cheng’s hands. She really couldn’t figure it out. This is just a little bit of a shame~www.mtlnovel .com~How could Godko be so happy?
Can this thing make a tool that is harder and more durable than stone?
But he laughed quickly, not because he figured out things, but silly following the son.
"Burn! Keep burning!"
Han Cheng put these small iron beads in his hand extremely cherished into a clay pot, yelled excitedly like chicken blood, and put more than a dozen mud bumps into the stove at once...
From this day on, the newly built stove in the Qingque tribe burned for five consecutive days before it finally stopped temporarily.
"Wow..."
"Wow..."
Han Cheng hugged the jar, which was not too big, but looked a little heavy, shaking it from time to time, with an idiotic smile on his face.
This surface is filled with iron beads large and small. This is the result of continuous labor over the past few days, which is about two catties.
This is the scale that the iron bacteria near the Qingque tribe have been scoured and accumulated.
With these iron beads, he became more confident in the following things.
With high-purity iron beads, the next thing you need to do is to heat and melt these iron beads to make a lump of iron.
After thinking about it, Han Cheng first put a layer of charcoal in the stove, and then put the iron beads in four clay bowls of different sizes and placed them on this layer of charcoal.
Then a thick layer of carbon was added to it and it started to burn.
Such simple methods and tools consume a lot of charcoal and time.
But now is obviously not the time to consider these. It is thank good to be able to get the iron out. How can there be any effort to consider the loss?
