The Ultimate Live Superstar

"666666!"

"True Alchemist!"

"Learn about the copper smelting addiction?"

"The anchor will start soon? Can't wait!"

"Fuck, are you finally going to make a copper axe?"

"Support, come on!"

The few words in the opening remarks instantly ignited the atmosphere in the live broadcast room!

The barrage suddenly increased.

It hasn't calmed down for a long time.

After calming everyone's emotions, Lu Yu continued:

"After several days of hard work, the relevant preparations are almost ready."

"Clay crucibles, copper materials, furnaces, blowers, everything..."

"Next, as long as you follow the steps and smelt these copper materials, you're basically done. However, before the official start, there is one more thing that we need to pay attention to, that is, modeling."

"The purpose of fusing the copper material is to cast it into the shape we want, not random."

"So, making molds is also one of the essential links."

Usually, the molds used for casting metal are mostly made of heat-resistant materials.

Such as platinum, quartz, silicon carbide.

But these things are not the first choice for Lu Yu.

Even if you can get it, there is no relevant tool to turn it into a mold that suits you.

Therefore, the above-mentioned materials are no longer within the scope of his consideration.

In the current situation, the most reliable is clay.

Molding with clay is also an ancient method of casting.

Convenient and easy to take.

The forming rate is also very impressive.

The production process is not as complicated as one might imagine.

It is nothing more than to use a sharp tool to describe the type of mold you want on the paved mud.

Finally, pour the molten liquid metal into it and let it air dry to fix it.

Nothing difficult.

But one thing that must be paid attention to is the soil quality of the clay.

It is best to use good quality dry clay.

Water content is large, not competent.

But the clay next to the water source is mostly wet.

So, have to find another way.

"Molding is the most critical part in determining the quality of the final product."

"Weaving baskets and baskets, the key is to close the mouth."

"Don't be careless, otherwise, all the previous efforts will be in vain..."

While speaking, Lu Yu had already returned to the house, put the bamboo basket on his back, and strode away from the camp.

Be prepared to try your luck in the woods first.

"Refractory clay is usually distributed around water sources, but there are exceptions, and there are also a small amount of distribution in rock or coal-measure strata."

"Many people ask me why I don't go to the river to look for it?"

"The fundamental reason is that the soil with too much water content is not easy to pour. Even if there is no sand, it is not a good choice. Although it is not impossible to use, it is best not to take this risk in order to be safe."

"Because there are more secure options for us to choose from."

After entering the jungle.

Lu Yu went around and found a rock dike splitting zone.

Drive forward along the overgrown ravines on the left bank.

While paying attention to his feet, he carefully observed the changes in the soil layer, and did not miss any clues.

Compared with the wet clay in the water source, the clay produced by the rock formation is mostly formed by the weathering of silicate minerals on the earth's surface.

The particles are larger.

The composition is also relatively close to the original stone.

This clay is called primary clay or primary clay by geologists.

The fire resistance of virgin clay is stronger.

It is also more capable of smelting operations.

into the Bronze Age.

In addition to fully mastering the method of metal smelting, people have also entered a new field for the application of other natural materials.

Clay is one of them.

In order to be able to smelt bronze more efficiently, people gradually gave up low-quality clay.

At this time, the native clay naturally became their favorite object.

Nowadays, in the remains of many ancient civilizations that have been discovered, more or less shadows of native clay can be seen.

The reason.

In fact, it is the inevitable result of the development and expansion of production technology.

...

Without direct sunlight and continuous heating.

Conditions in the jungle finally improved.

A breeze hits.

Much cooler.

It sets off the last tranquility before the rainy season breaks out completely.

Carrying a bamboo basket.

Walked forward for a while.

The trend of the fault zone of the rock dike suddenly changed.

Immediately afterwards, a huge deep pit came into sight for no reason.

Bend over to see.

The deep pit fault is obvious.

It should be formed by earthquakes, flash floods, or crustal changes in the island.

In the pit, the root systems of many trees can be seen crisscrossing each other.

The exposed soil layer of luo is gray-white and looks very delicate.

It was the native clay that Lu Yu was looking for.

"Look."

Pointing to a soil layer, Lu Yu raised his voice and said:

"There's what we want in here."

"The native clay contained in the rock formation is a very perfect soil."

"With them, our molds will be available, and we will find a way to get some up."

The words fall.

Without the slightest hesitation, Lu Yu jumped up immediately.

From the edge of the pit to the bottom of the pit.

I found a place with a lot of soil and watched it.

As a result, do not see do not know.

Startled at a glance!

Lu Yu's brows were instantly overjoyed, and he almost laughed out loud.

this soil.

Not your average virgin clay.

But very rare kaolin!

You know, high-quality kaolin, whether it is fire resistance or adsorption, is second to none!

"Everyone, let's see what I found..."

After grabbing a handful of kaolin, Lu Yu opened his palm.

Put it under the lens.

"food?"

"The anchor, I read less, don't lie to me, isn't this just ordinary dirt?"

"Look at Yushen's little expression, won't you find something to eat again?"

"Eat dirt?"

"Fuck, I seem to have seen this kind of soil in Jingdezhen, what is it called?!"

"Don't give up on Yushen, let's reveal the answer quickly!"

Looking at the bullet screen, Lu Yu laughed.

Eyes full of joy:

"Brothers, this is no ordinary virgin clay."

"It's kaolin!"

"Kaolin is a very high-quality non-metallic mineral, most of which are clays and claystones dominated by kaolinite clay minerals. Because of its whiteness and fineness, we Chinese call it dolomite."

"Kaolin clay is mostly dull, and when it is pure, its color is white and delicate. If it contains impurities, it can have gray, yellow, brown and other colors. Depending on its origin, its appearance can be in the form of loose soil blocks or dense rock blocks..."

After a brief introduction, Lu Yu moved closer to the camera again.

Take a pat on the details of the clay in the palm of your hand.

Then went on to say:

"The kaolin here, look at the color, the purity is really evident."

"Pure kaolin, white and delicate, in the form of soft clay, has good physical and chemical properties such as plasticity and fire resistance. Its mineral components are mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite and quartz, minerals such as feldspar.”

"Kaolin is very versatile, mainly used in paper, ceramics and refractories, and it's perfect for casting moulds."

The density of kaolin is between 254-260 g/cm3.

The melting point is about 1785 ℃, and it is very refractory.

At the same time, it also has plasticity.

Wet soil can be molded into various shapes without breaking, and it will stay the same for a long time!

"Kaolin is highly regarded in China and is named after Gaoling Village, Jingde Town, Jiangxi."

"However, it is not unique to China."

"In nature, it is widely distributed and exists in a large amount, almost 20 billion tons."

"Among them, there is a very large kaolin deposit in the Australian mainland, which is the closest to us, so it is not surprising that kaolin can be found here."

talking room.

Lu Yu had already unloaded the bamboo basket.

Scrape off the soil in one fell swoop.

It was filled one by one.

Because it's just to build a mold, it doesn't take much anyway.

It's almost enough to get half a basket.

Rather than taking them all back to the camp, they'd better leave them here and take them as they go.

Also a lot more convenient.

"Okay, brothers, it should be almost the same."

"These soils are enough for us to create a perfect mold..."

Carrying the bamboo basket on his back, Lu Yu walked around in the pit.

Finally, I found a relatively low place, climbed up, and returned to the camp according to the original road.

...

to the place.

Lu Yu put the clay aside first.

Turning around, he turned over the wooden slat tile mold that was used to make the tile.

"This tile mold can help us a lot, and the size is just right."

"Otherwise, we have to do it all over again."

Done.

Lu Yu sat down beside the furnace.

Put the tile mold on the muddy stone slab.

Then, I poured a large handful of kaolin into it, and it didn't stop until it was completely filled and compacted.

With this clay mold, all you need to do next is to carve the desired shape on it.

"Because the recovered copper material is limited, there is basically no hope of getting a large jungle axe, but it is more than enough to get a Viking battle axe for fun."

Holding a stone knife.

While carefully drawing on the clay mold, Lu Yu explained to the audience:

"The Viking battle axe is the most common weapon used by the Vikings."

"In the age of cold weapons, almost everyone has one. It is improved from the commonly used logging axe. Talk again."

"The weight of the Viking battle axe is often not very heavy. It can be thrown and a melee weapon. It is much lighter than a sword."

"And easy to operate, far less bulky than people think, it is a short and powerful type, and the requirements for materials are not so harsh, it should be our best choice now..."

soon.

Chat and draw.

It only took less than five minutes.

Lu Yu carved the rough shape of the battle axe deeply on the clay mold.

The length of the axe blade is moderate, and the curved blade surface is very exaggerated.

This is also one of the characteristics of the Viking battle axe.

It is precisely because of this design that Vikings can easily concentrate their lethality at one point when fighting with a tomahawk.

Helmets and chainmail protection can be broken very easily!

In fact, in the history of northern Europe, it is often seen that Viking warriors split the enemy's armor and men with an axe.

"Okay, here, the mold is basically ready."

"Next, let's go straight to the subject-"

then.

Lu Yu didn't stop.

Hastily fetched the fire and lit the firewood in the furnace.

Grasp the blower's bow drill and keep pushing and pulling.

"Hoohoo-hoo-!"

The flames are big and small.

The firewood in the furnace finally burned completely.

see.

Lu Yu first put the clay crucible with copper grains into the firewood.

Then, pour another circle of charcoal.

"After the fire is burning, direct the charcoal."

"Let the charcoal fire wrap the crucible. During this process, be sure to increase the firepower as much as possible while the crucible is heated evenly. Don't be stingy with the charcoal, and don't be stingy with your own strength—"

Not even a word has been said.

Lu Yu picked up the drill bow again and pulled it frantically!

"Come on Feather God!"

"Hand speed is invincible!"

"Copper smelting + unicorn arm =?"

"Crazy output ing!"

"There are new materials in the ghost animal area!"

"incredible……"

...

It took about ten minutes.

Charcoal fire in a furnace.

more and more red.

The clay crucible has also undergone subtle changes.

Although it hasn't turned red yet, judging from the structure of the clay surface, the temperature profile in the furnace seems to have already reached its peak.

Looking at the situation in the furnace, Lu Yu didn't give up, and poured another pile of charcoal into it.

"Maintaining furnace temperature is the key to smelting metal."

"We must add charcoal in time."

"Don't be troublesome."

"Because once the temperature drops, all previous efforts will be in vain."

talking room.

An hour passed.

At this point, the furnace has eaten three waves of charcoal.

The bottom of the crucible has also reacted very clearly.

Unconsciously, it turned completely red.

The copper material inside seems to be melting little by little...

see here.

Lu Yu finally breathed a sigh of relief.

But the movement of the hand did not stop.

Still holding the bow drill, pushing and pulling constantly.

"When the clay crucible turns red completely, the copper material inside will naturally turn into copper water."

"But it's going to be a very long process."

"Even if everything goes well, it may take another hour."

"During this time, be sure to keep an eye on the furnace temperature, and if necessary, you can add charcoal in time..."

The voice fell.

Lu Yu summoned the drone in front of him, zoomed in on the camera, and took a picture of the situation inside the fireworks.

The drones of the system are made of special materials.

Don't be afraid of high temperature.

Even extreme violence cannot destroy it, not to mention the fire of this thousand and eight hundred Baidu, even if it is probed into the magma, it is a trivial matter.

next second.

After zooming in.

The audience clearly saw the changes in the copper material in the crucible!

Call it amazing!

"666666666666"

"It really melted!"

"Fuck you, awesome!"

"Feather God's drone is too hard-core, isn't it? It's okay to put it into the fire?!"

"After all, it is exclusive to local tyrants!"

"It still feels like drones are a little better!"

"233333333"

...

soon.

Another hour passed.

During the period, apart from chatting with the audience word by word, Lu Yu added another batch of charcoal to the stove.

now.

The continuous high temperature finally burned the crucible to a rosy red, which was very eye-catching.

And the copper material inside seems to have turned into water.

see this scene.

Lu Yu wiped the sweat from his forehead and said:

"It's almost the same when it's burned to this extent."

"Okay, next, let's find something to clamp the crucible out, and then pour the copper water inside on the clay mold-"
