These copper blocks have just solidified and have different shapes, but the temperature is still very high. The color is not pure copper purple-red, but more redder.

Xu Chen is familiar with the components of various ores. Although the specific content of the ore cannot be detected at present, whether it is chalcopyrite, copper ore, or chalcopyrite or other types of copper ore, it cannot be a complete copper compound, but it will be mixed with various associated ores such as silver, zinc, cadmium, nickel, iron, and some will even be mixed with gold.

Most of these metal impurities are filtered out in the form of slag, but under continuous incineration of nearly 1000 degrees, some of them will be mixed into the copper juice and flow out together. Especially zinc, the melting point is only more than 400 degrees, which is not much higher than lead and tin. Ordinary stoves can melt it. Therefore, using this simple method, it is absolutely impossible to smel out too pure copper.

In fact, for Xu Chen, he does not need too pure copper. It is best to contain some tin and lead. The copper obtained in this way may be more useful.

Unfortunately, the copper blocks obtained at the moment do not look like they contain these two metals.

"Bang bang bang..."

Xu Chen used a small wooden stick to clamp a hot copper piece onto the stone slab and gently smashed it with the stone a few times. The copper piece slowly expanded into a bumpy copper piece, emitting a purple-red metallic luster under the strong sunlight.

A lot of copper blocks fell into the sand were digging out, which looked like two or three pounds. Xu Chen had a lot of pieces of them in a pottery bowl.

It has been more than ten minutes since time passed.

Four kiln workers are still busy dealing with the remaining kiln fire.

Xu Chen estimated that the copper inside the mold should have been completely solidified, so he gently knocked it out with a wooden stick to open the mold, revealing the purple-red copper ware inside.

These bronze ware are not big, and the mold is also very simple to make. Two small knives, one small sword, and three small hammer heads of different sizes. The largest one is a square copper plate with a side length of about two centimeters thick.

This copper plate alone almost used up half of the smelted copper.

After all the bronze ware was knocked out of the mold, they used a pottery pot to scoop water and poured it over and over again. The steam of the water attracted four kiln workers. When they looked at the strange-style purple-red metal objects in front of them, they seemed to see the most incredible thing in the world, and couldn't help but exclaim again.

The water that was burning red just now was obviously still hot, but in the blink of an eye it turned into a strange solid.

After pouring water several times in succession, Xu Chen took the copper ware to the puddle to wash it clean after it was no longer hot.

"Take it, finish the work and go home!"

Xu Chen was still happy and still laughed so hard that he couldn't stop. He put some scattered copper pieces and a few small objects into the basket, and then pointed to the most important piece of copper plate for a kiln worker to help him carry it.

At first, the savage didn't care, but he couldn't help but exclaim in his hand.

"Moxie Gaga?"

The other three kiln workers rushed over and asked nervously.

"Chongga!"

The kiln worker held the heavy copper plate in both hands, and his face was full of incredible expression.

"Try it!"

Someone grabbed it in his hand and his face instantly showed a look of horror.

This thing is a little bigger, but it is actually very heavy. Although the ore at the beginning is also very heavy, it is completely incomparable to this copper plate.

Of course, they have also seen more dense things, such as gold. A small amount of gold appears in the six tribes every year for party trading. However, most of the dog-headed gold in nature is very small in size. Even if the thumb size is large, it looks like half a pound per pound. Moreover, those are naturally present, and everyone is not surprised.

The copper plate in front of him was different. He was a kiln worker himself. He was naturally surprised to see it burned out of a pile of messy stones.

This palm-sized copper plate is about five kilograms.

The comparison between weight and volume obviously exceeds the psychological range of a group of savages.

So on the way back, four kiln workers rotated and held them in their hands. After returning home, they even showed the achievements of their hard work in the kiln factory next to the room to show all the men and women.

Although Mu Ba and others were very curious about these things that exuded purple-red metallic luster, heavy and strange, they were a little confused about how many big men had worked so hard for so long.

The most important thing is that Xu Chen explained that this kind of thing called copper is useless now, and it is almost the same heavy gold that comes back from pottery.

Why are you getting useless things?

So after a group of men, women, young and old watched the noise, they all scattered and went to work their own work.

The four kiln workers who couldn't show off were also frustrated. They put the copper plate in Xu Chen's room and went to do something else with their heads hanging down.

This is the most frustrating and meaningless thing they have done since they became kiln workers.

Not only does it take time and effort to achieve little results, but it is useless.

Fortunately, it was something Xu Chen wanted. If they burned this thing themselves, they would probably be scolded by their mother.

Faced with the emotional changes of the tribe members, Xu Chen didn't care.

Primitive people still do not understand the significance of smelting metals for the progress of human civilization.

Because they are still at the stage of worrying about the simplest food, including the houses that are already in existence, linen, pottery, water wells, etc., which are actually not essential. It is just because Xu Chen needs it, so they appear one by one.

In fact, what Xu Chen really did the most influence and meaningful thing on the primitive tribe was the bows and arrows and fishing nets that he ignored the least.

These two things greatly changed the survival status of the entire tribe and greatly enriched the food source and quantity.

In fact, in the long history of human development, metals did not appear as production tools for a long time, but existed in the form of ritual vessels.

The social structure represented by the ritual vessel is that the class has been produced, which means that human beings’ status in social production and life is no longer equal.

It is still the matriarchal clan stage of the Paleolithic era, with primitive humans having equal status. A tribe is a family that is in love with each other. There is no high or low status or magnitude of status, so it is impossible to produce ritual instruments representing different identities and statuses.

The only thing in the clan that shows different identities is the bird feathers inserted on the woman's head.

But this does not mean power, it only means age and age.

Of course, it is not that there is nothing that represents power at all. There is still a very special existence, that is, the scepter in the hands of the patriarch and the witch.

But the source of the power of the scepter is not human, but God. It represents the power and wisdom of God, and has nothing to do with power.

Therefore, even if the smelted copper is very exquisite, very special and incredible, for the primitive tribes at present, this exquisite and special nature is just beautiful and decorative. Anyone can own it. It will not have the possibility of being superior because of its rare value, and there will be no older people who want to occupy it and use it as their own personal belongings to demonstrate and enhance their identity and status.

The rare gems such as gold, turquoise, amber and a large amount of copper ore exchanged back in front were just Xu Chen's favorite and curiousness for Moba and all the tribesmen. Now that he burned the copper ore into these strange copper blocks, he could not enhance Xu Chen's power at all. At most, he used his own methods to make more magical and meaningless decorations.

Seven or eight new bronze ware and a bowl of strangely scattered copper blocks were placed on the brick desk in the dormitory.

There is a piece of suede underneath.

These crudely cast bronzes exuded a charming purple-red metallic luster.

Two half-foot-long knives, one foot-long sword, and three different hammer heads. Most of these small pieces are only half a pound per pound. The heaviest one is the square copper plate. It is picked up and put down, and it falls on the table and makes a dull sound.

Xu Chen picked up a few things and watched them carefully. After using a wooden ruler to make a simple gesture and measure them, he then took a stone axe and cut back a few pieces of wood. He sat under the eaves at the door and started to chew and chew.

Half a day passed by. When the sun began to set west, there were already a few decent things in front of Xu Chen.

Two copper knives with handles, one copper sword with handles, and three copper hammers with handles.

After installing the handle of the knife and hammer, Xu Chen found a flat and delicate stone, took it to the edge of the well and started watering and polishing.

The copper is soft and is not suitable for knives, but he really doesn't know what to do when he smelted this first time.

Hotpot is a good thing, but it is obviously not suitable at the moment. When eating green vegetables and grain porridge every day, it is not enough to be so crazy to enjoy it.
