Therefore, next to the copper furnace, there is at least a tin pot and a furnace that mixes copper and tin to produce bronze. Pen, fun, and www.biquge.info

Normally, copper ore is usually surrounded by tin ore.

The copper mines in Liucun are no exception.

So, the ore they transport also contains a small part of tin ore.

Blister copper is soft and has a high melting point, making it unsuitable for pouring.

Even if it is poured into an instrument, the service life is not long. If it is made into a weapon, not to mention compared to the alloy iron produced by the system, even compared to the black iron wood that grows naturally on the Great Wilderness, it is slightly inferior.

Once tin is added, according to a certain ratio, the smelted bronze is much harder than pure copper, and it is very wear-resistant.

In fact, the name of bronze was given to it by later generations. Because it is buried in the ground all year round, it will become cyan after the rest of the reactions such as oxidation. You must know that the bronze that was originally produced was yellowish to reddish.

Three furnaces, one for copper, one for tin, and finally one for bronze, which was then poured directly.

In this way, it would take at least fifteen clansmen to be able to keep busy.

However, there are only about 30 men in Wang Village. Except for other things to do every day, Wang Hao can draw up to seven or eight people. Savages don't have to worry about them leaking their skills, but they're too stupid to do some hard work. And such an important place as the copper smelting furnace cannot be touched by those people from other villages for the time being. Therefore, after careful consideration, Wang Hao finally decided that only one copper furnace will be used at present.

The refining of bronze is divided into three waves.

On the first day, the molten copper is refined.

Wait until the next day, smelt tin.

On the last day, tin and copper are melted into alloy bronze in a certain proportion, and then poured through a clay crucible to get what you want.

Today the sun is shining, and it is another sunny day.

Wang Longtou looked at the clouds in the evening, and then told Wang Hao that such good weather would last for a long time. At this time period, for Wang Hao, copper smelting is absolutely enough.

Today is the first day of steelmaking. Sacrifices and prayers are essential.

The Great Wilderness is different from the earth, in the Great Wilderness, there are evil gods who can enter the human brain domain, so Wang Hao will not be too surprised if anything strange happens.

The theory of ghosts and gods is very tenable in the Great Wilderness, so these seemingly superstitious and useless prayers and sacrifices, Wang Hao is still unswervingly ready to inherit them.

Wang Lung has now become the same figure as the clan elder in the village. On occasions like this, he always presides over them.

There is no way, Wang Hao is good at everything, but he just can't remember those oral prayers, even if he teaches them more than ten times.

When Wang Long finished praying, Wang Hao prayed again. If you get closer, you can still hear Wang Hao chattering, let the ancestral god bless this copper furnace from exploding.

In fact, how can an ordinary steelmaking furnace explode for no reason without putting explosive materials, but Wang Hao has a phobia of explosions, although he understands it in his heart, he just can't help but worry. Just like many people know, those fleshy caterpillars are not lethal at all, but every time you see them, you will feel creepy.

The inside of the stove has been burning since last night, and now the preheating has been completed.

The one-meter-thick furnace wall completely isolates the heat inside, and even if it is close to the furnace wall, you will not feel the temperature.

With Wang Hao's order, a clansman standing on the top of the furnace added the charcoal piled up on the side with a shovel.

The four savages twitched their bellows with all their might, fueling the charcoal.

When the temperature rose to a certain level, a clansman pushed a wheelbarrow full of mineral particles and carried it up the slope of bricks and stones on the side of the copper furnace.

After pouring it on the top of the furnace, the people who had been waiting there filled it with shovels along the top feeding opening.

Because it was the first time to smelt copper, this time only half of the material was added for the sake of insurance.

After Wang Hao saw that it was almost from the observation hole, he asked the people above to stop.

Moving the lid on the top and closing the feeding hole, the four savages desperately puffed up the wind below.

Wang Hao once heard that some large factories only need 30 minutes to smelt a furnace of copper with those electrically heated instruments.

In the Great Wilderness, it is impossible to reach this time.

Because it was the first time to smelt copper, the experience was insufficient, and the temperature in the furnace did not reach the requirements, so copper was added.

As a result, the fire in the furnace collapsed, and it took a long morning for the temperature of the inner furnace to rise.

During this period, the charcoal fire alone was added twice.

The strength of the people of the Great Wilderness is great, but it does not mean that it is endless.

Wang Hao found that four air vents were completely redundant, but in fact, two air vents were completely sufficient to support combustion.

Because of this, the four wildlings were divided into two groups. Take turns resting. After all, the repetitive mechanical movement still has a very large damage to the muscles, and even the people of the Great Wilderness cannot insist on pulling the bellows all day.

Although Wang Hao knew the principle of copper smelting, it was the first time for him to do it. Although there were a series of small problems, everything was going in a good direction.

Wang Lung was on the side, writing down all these questions on the bark. In this way, when they smelt copper next time, they will know to avoid these problems.

After lunch, the scorching sun was in the sky. Under the exposure to the sun, even Wang Hao felt a little uncomfortable, not to mention the clansman who was in the highest temperature when he added materials directly above the copper furnace.

But fortunately, at this time, I finally saw traces of melting of the copper ore from the observation hole.

Seeing this situation, Wang Hao was excited.

"Come on, when you smelt copper, your wages can be increased by 20%!" Nothing is more tempting than black ironwood money. Wang Hao's words made everyone want to do it desperately. Even the vicious sun in the sky is not so hateful.

"You can add whole pieces of fish to your food for the night!" This is the meaning of the translation of the words of the savages. After such a long period of domestication, these savages have understood some simple human words. Especially when it comes to eating, they have an unparalleled talent, and it is often said that they can remember it all over again, and it is almost like a hairball.

Because of the monotonous cooking method, the offal of animals that can be made into food on the earth is not suitable for consumption in the Great Wilderness.

So, most of it was boiled and mixed with edible plants that were ubiquitous during the season, but didn't taste very good, for the savages and captives.

Only when they exceed the standard of work or have a very good performance can they eat a delicious boiled fish like ordinary people.

Those fish that have now been eaten by the people of Wang Village are supreme delicacies to them.

After listening to Wang Hao's words, these savages naturally took out the strength to eat milk and pulled the bellows whirring.

It didn't take long for the molten copper to sink to the bottom of the furnace.

And the burning charcoal, the slag like semi-solidified magma, all floated on top of the copper water, and it looked particularly strange.

Lime powder is added to the furnace as a sinking accelerant. By midnight, it was finally time to open the gate and release copper.

Wang Lung held a long iron tong, clamped a clay pot as thin as a large bowl, and attached it to the copper furnace with a nervous face.

"Don't be afraid, I'm going to open the gates!" Wang Hao said to Wang Lung.

Wang Lung nodded, assuring that he had absolutely no problem.

When Wang Hao opened the gate, the orange-red, dazzling copper water flowed into Wang Long's clay pot like magma.

There was a little stagnant water in the clay pot, and under the high temperature of the copper water, it immediately 'rattled', and then turned into a white mist.

Although Wang Lung said that he was definitely not afraid, when he really saw the power of the copper water, he still trembled with fear after feeling the high temperature contained in it from a distance of more than a meter. His hands trembled, and the clay pots were almost knocked over.

He was like this, and the four shallow savages were even more unbearable.

They were first startled by the evaporation of the copper water, and then after feeling the high temperature contained in the copper water, they were so frightened that they knelt on the ground and bowed to the copper water.

They didn't know that it was copper, but in the eyes of the savages, it was fire.

Although the power of fire is powerful, it cannot be seen or touched. Never heard of anyone who could condense the fire into a ball.

When the savages saw the copper water, they thought it was made by the flames they condensed together.

The untouchable flame has so much power, it can burn the forest and kill everything, so how powerful is the crystallization of this flame?

After worshipping the copper water, the savages suddenly thought that this kind of thing was actually made by Wang Hao. That shows that Wang Hao is a person who is even more powerful than flame crystallization.

Thinking of this, they all kowtowed to Wang Hao again.

Wang Hao couldn't understand what these savages were thinking, anyway, he was used to it a long time ago.

These savages kowtow not once or twice.

They will kowtow to what they eat, kowtow when they see giants, and even kowtow when they see tiger toothfish that have been caught. Seeing Tongshui this time, Wang Hao would feel strange if they didn't kowtow.

It's just that there is no time to care about them at this time, and seeing that the clay pot is almost full, Wang Hao immediately closed the valve.

After changing the clay pot, Wang Lung picked it up again under the copper furnace.

With experience this time, he was not as frightened as he was the first time, but he was also very careful.

This furnace of copper ore has a full seven jars of copper water, although the last tank has a lot of impurities, but there is no problem, anyway, they need to be smelted again.

After cleaning up the slag, the fire was not extinguished, and Wang Hao planned to practice the tin while it was hot.

When the clansmen finished adding ingredients, they looked at the tin ore that melted rapidly. Wang Hao slapped his forehead suddenly, and then said, "Oh, why am I so stupid!" (To be continued.) )
