Hand rubbing nuclear fusion live in the wilderness

Chapter 95 Copper Alchemist
It took half a day for Han Yuan to dig away a lot of the soil around the piece of copper on the ground, but the piece of copper is still not completely exposed.

This single piece of copper is not small in size. The part that has been dug out is estimated to be at least about half a cubic meter. Only a small piece is exposed to the ground, and most of it is buried in the ground.

For the time being, he couldn't take all of such a large piece of copper back, so he could only choose to chop off a few pieces with an iron ax and put them in a bamboo basket.

After harvesting enough elemental copper, Han Yuan searched around again, and successfully found a few pieces of chalcocite ore.

This chalcocite is a typical rich ore.

Not to mention the elemental copper, even the chalcocite ores found have a copper-green patina, and the distribution is very wide. One can tell at a glance that the copper content is not low.

Throwing the few pieces of chalcocite found into the bamboo basket, Han Yuan put the bamboo basket on his back and was ready to return.

The audience in the live broadcast room saw him collecting chalcocite ore and bringing it back. Many people were puzzled and asked why.

After all, in the eyes of most people, is it unnecessary to smelt copper instead of using high-quality single copper?

Seeing the barrage of inquiries, Han Yuan smiled and said, "Aren't you happy that I'll show you how to refine metal copper?"

Demonstrating copper smelting is just an excuse. As for the real reason is to complete the smelting task, this cannot be said.

This reason is justified, and the audience didn't think much about it, but became happy, after all, they can see what they like to watch.

Returning to the camp with a bamboo basket of heavy elemental copper and chalcocite ore, Won lit a bonfire.

The melting point of copper is much lower than that of iron. Even simple copper has a melting point of only more than 1000 degrees.

If it is mixed with some lead, tin, sulfur and the like, the melting point can even be as low as below [-] degrees.

The main component of chalcocite is cuprous sulfide, and its melting point is much lower than that of simple copper. The kiln and charcoal previously used for ironmaking can be used for copper smelting.

As for the kiln and charcoal, he had already fired them here when he was building the concrete wall two days ago.

Including the hand blower, he made a new one.

The blower this time is not the crude thing made of bark like last time, but made of planks sawed with a wood saw, which is stronger and more durable than the previous ones.

After the bonfire is lit, the old method is to add a layer of charcoal in the kiln first.

Then it is completely ignited, and then a layer of charcoal and a layer of chalcocite are added inside, which is no different from ironmaking.

It's just that the reaction inside will go through twice.

For the first time, the high temperature reduced cuprous sulfide, the main component of chalcocite, to copper oxide.

The second time is that under the action of high temperature, charcoal reduces copper oxide to elemental copper.

So charcoal smelting copper is also possible.

Time passed quickly, in the blink of an eye, several hours passed, and the copper in the kiln was basically restored.

The Korean won was pushed directly into the kiln, and then the charcoal that was still burning inside was scraped away to find the elemental copper.

After a while, he found the restored brass in the charcoal.

Because the temperature in the kiln has exceeded the melting point of copper, the copper smelted this time is somewhat different from the condensed pig iron.

The smelted copper melted into grains, and its color was golden yellow with a hint of purple awn.

It was very troublesome to use iron tongs to pick up the copper particles in the charcoal, so Han Yuan simply brought a basin of cold water and poured it into the still burning kiln.

Immediately, hot air and mist filled the sky with fine dust rising into the sky, covering the sky and covering the ground.

One pot was not enough, and another pot was added, until all the charcoal in the kiln had cooled down, he went straight to look for the golden copper particles inside.

After a while, all the smelted copper particles were collected, and finally a small half pot was harvested.

These copper particles are of different shapes, piled up in the pottery basin, shining golden and dazzling light, just like gold, but with a hint of mysterious purple, it is very beautiful.

Seeing that the copper particles have been extracted, discussions started in the live broadcast room.

[True Copper Alchemist (dog head)]

[Why do I feel that smelting copper and iron is so simple? 】

[Why does the smelted copper look like gold, so golden? 】

[I've collected broken copper and rotten iron, I changed the washbasin and bathtub! 】

[As far as the host has these, I can buy them at most fifty cents. 】

[Copper is a strategic resource. It would be a pity if this copper mine was in China. 】

Han Yuan put away the copper grains, glanced at the sun that had begun to slant west, and said.

"The chalcocite ore collected in the morning has been extracted, and now the sun is about to go down, so today's live broadcast will probably end here first."

"Tomorrow I will build a thicker kiln, and I will show you how to do it in the last few days. Just remember to watch it."

Hearing this, the audience in the live broadcast room sent bullet screens one after another to ask what the show was doing.

It's a pity that the Korean Won closed the live broadcast too quickly, causing many viewers to see a black screen before sending out the barrage, and many people were itchy.

After the broadcast was off, Han Yuan started to make dinner for himself and his two little ones.

I just ate something casually at noon, so dinner naturally had to be bigger.

As for what to eat tonight, he has already planned it.

The eye spot bream that has been raised for two or three days will become hungry and thin if it is not eaten.

The spotted sea bream that has completed its mission is swimming happily in the pool, not knowing what kind of crisis it will face.

Waiting for the water in the pool to drain, I noticed that the dangerous eyed snapper started to jump wildly.

It's a pity that Han Yuan quickly held him down, and then he stabbed his head back.

The spotted sea bream, which was struggling non-stop, was like a dried salted fish, unable to even turn over.

After a comfortable dinner, Han Yuan sat at the door of the wooden house and opened the system task panel.

After completing the smelting of chalcocite today, the last smelting exploration task is only three short, and it is expected to complete the rest in the next two days.

And tomorrow's arrangement, he has already planned.

Since it is a show operation, it is natural to choose the most familiar one.

Knead pottery and burn porcelain!Still the glazed one.

It just so happens that he knows and is familiar with this set of procedures.

More importantly, he also found feldspar and quartz in the forest.

There are feldspar and quartz, plus clay, crushed and mixed with plant ash water, and the enamel can be initially produced.

Ceramic and enamel are two new materials that can be used to complete side quests.

In order to present all the complete steps tomorrow, he just made a kiln this evening, prepared all the materials and went to sleep.

As for the rest of the work, including making tools, embryos, and grinding glaze water, etc., it will be put to tomorrow.

The next morning, Han Yuan woke up, washed up, ate some breakfast, and started the live broadcast.

When the live broadcast started, countless viewers poured in.

【First! 】

[What is the operation of the show today, anchor! 】

【Please finish your sentence next time, okay? It's very annoying! 】

[Gan!You ran so fast last night! 】

[The anchor is so short, can you give me your address?I will send you something to ensure that you can grow up in the future! 】

　Two consecutive updates have been delivered, and there will be more in the afternoon, please follow-up, monthly and recommended tickets.It's the beginning of the month, and everyone will get two guaranteed monthly tickets.
