"Melted!"

"It's tin ore!"

After the charcoal fire continued to burn for a while, the bottom layer of smashed tin ore began to melt.

Han Cheng, who saw this scene through the hole on the side of the stove, shouted excitedly.

The rest of the people who had been waiting for news on the sidelines also cheered.

Han Cheng looked here for a while, and saw that the flames began to spread through the tin ore that began to melt at the bottom and began to spread to the charcoal above, and the gradually melting tin ore had a tendency to flow outward, so he quickly blocked the opening at the bottom with charcoal and clay.

"Huhu~Huhu~"

The person who pressed the wind and purred had already changed to the third.

Han Cheng looked diagonally down from the top of the furnace, and saw that most of the ore inside had melted, so he asked people to poke the hole that was a little higher open, and the melted slag began to flow out of that hole, and the heavier molten metal was left under the furnace.

"Put the clay pot and open the stove!"

When the ore in the furnace had melted and the slag was almost flowing, Han Cheng gave an order, and immediately two people came over with long wooden sticks.

He put the thinner end of the stick against the hole under the stove, and with a sharp force, the blocked hole was pierced.

The stick was quickly withdrawn, and the molten metal flowed out through the holes in the stove and landed in the clay pot.

Even though they had seen copper smelting more than once in the tribe, at this time, when they saw a good stone being burned into water and flowing out, everyone couldn't help but feel a burst of surprise in their hearts.

After cooling for a while, the pot was smashed, revealing a jar-shaped metal ingot.

The shape of this metal ingot really looks a bit like the word 'gold'.

Perhaps when the ancestors made words, they came from this aspect.

Looking at this coarse tin ingot, Han Cheng rose to the idea of making bronze.

Letting most of the people go to mine the newly discovered tin ore, Han Cheng left a few people by his side, and added charcoal to it while the charcoal fire in the furnace was still not extinguished and the temperature was still there.

Then he took some coarse tin from the tin ingots and put it in the furnace to continue to melt, and at the same time put a copper hammer made of blister copper into it, and melted it together with the coarse tin.

The ratio of tin to copper is roughly one to two.

I remember that when I used to read the general history of ancient times, I once saw a record about the ratio of copper and tin, that is, 'gold has six qi'.

Six parts of raw materials, one part of tin and five parts of copper are suitable for what to do, and two parts of tin and four parts of copper are suitable for what kind of utensils......

What proportion of bronze made of copper tin and what kind of utensils are suitable for making such things, Han Cheng can't remember clearly.

Even if he used pinyin to record some things on the pottery tablet before, it was not possible.

Because when it was first written, he was vague about the subject.

But there is nothing to regret, with copper and tin, and know that 'gold has six qi', the rest only need to make these different proportions of bronze, and slowly you will be able to know what they are suitable for.

The wind continued to whirl, and the smoke from the stove became fainter and lighter, eventually turning into inconspicuous green smoke.

As time passed, and after several people who were purring according to the wind, the blister copper and tin in the furnace finally melted and mixed together.

However, Han Cheng did not turn on the stove immediately, because he remembered an idiom - perfect fire.

It is said that when smelting bronze, the best state is achieved.

Now the two metals in the furnace have melted, but they have obviously not reached the point of perfection.

After waiting for a while, the fire finally became pure green as the flame continued to burn.

Han Cheng no longer hesitated, picked up the long stick he had used before, and stabbed hard at the hole, and the cyan molten metal flowed out and fell into the clay pot below.

In fact, at this time, it is best to pour the melted copper juice directly into the model, so that after cooling, you can directly get the bronze utensils with a little correction.

However, Han Cheng smelted bronze in a hurry this time, in order to confirm whether the copper and tin he made were good at refining bronze, and there was no model at all, so he could only get the bronze juice into the jar, wasting this good opportunity to cast bronze in vain.

The clay pot was broken again, and a cyan copper ingot appeared in front of several people.

Han Cheng looked at this piece of bronze and reached out to touch it, it may be a psychological effect, a heavy and hard feeling was transmitted, and the smile on his face couldn't be suppressed.

After a while, Han Cheng picked up another coarse copper hammer from the side and hammered it fiercely against this bronze ingot.

"Dang!"

A metal clash sounded, and Han Cheng was bounced up with a coarse copper hammer in his hand.

Bringing the hammer head to his eyes and looking closely, there were some marks on the rough copper hammer head.

There are also some places on the bronze ingots that have been smashed flat, but not as badly as the rough copper hammer head.

Sure enough, the bronze smelted after adding tin was much harder than the blister copper that was simply smelted before.

"Hahaha...... The Bronze Age is coming! ”

The smile on Han Cheng's face became more and more vigorous, and finally turned into a hearty laugh that he couldn't suppress.

The few people who followed him, Senior Brother Sha, didn't understand what the Bronze Age was talking about, but the joy from the bottom of God's heart was that they knew and understood that their tribe had another good thing.

They were infected by the Son of God, and they all laughed along.

The westerly sun shone on the copper mountain, on the smoking furnace at the foot of the copper mountain, on the blue copper ingot placed next to the smoking stove, and on a group of laughing people.

Heaven and earth are furnaces, creation and transformation are ten thousand work, yin and yang are carbon, and all things are copper.

While the Qingque tribe got the copper, the people in the tribe have become different from before after the tempering of life in the past few years, and they are very different from other people in this era.

The long legs carried a wooden stick in one hand and the lucky charm hanging around his neck with the other hand, and smiled very happily.

On the one hand, it is to be happy that there is an extra good thing in the tribe.

On the other hand, because he provided the tribe with information about the copper mine and found the tin mine, not long ago, the honorable Son of God announced that he would be relieved of his slavery status and make him a citizen of the Qingque tribe.

And not just ordinary citizens, but first-class citizens with beautifully cearthened identity cards!

Such a lucky thing befell the head, how does this make Long Legs unhappy?

He held the lucky charm tightly, reluctant to let go, thinking that the reason why he was luckier than all the slaves was because of the lucky charm......
