The Ultimate Live Superstar - Chapter 396

“666666!”

“True Alchemist!”

“Come on copper addiction?”

“Anchor is about to start? Can’t wait!”

“Lying trough, are you finally going to build a copper axe?”

“Support, come on!”

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

The barrage suddenly increased.

It hasn’t subsided 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 clay crucibles, copper materials, furnaces, blowers, everything…”

“Next, as long as you follow the steps and melt these copper materials, you are basically done. However, before the official start, there is one more thing that we need to think about, that is, to model.”

“The purpose of melting the copper material is to cast it into the shape we want, and it does not come randomly.”

“So, making molds is also an essential part.”

Usually, the molds used to cast 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 it can be done, there is no relevant tool that can turn it into a mold suitable for you.

Therefore, the above materials are no longer within his consideration.

Judging from the current situation, the most reliable one is clay.

Molding with clay is also a method of casting found in ancient times.

Easy to access.

The molding rate is also considerable.

The production process is not as complicated as expected.

It is nothing more than the use of sharp tools to describe the type of mold you want on the flattened mud.

Finally, pour the melted liquid metal in and let it dry and fix.

There is nothing difficult.

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

It is best to use high-quality dry clay.

Those with large water content are not competent.

But the clay beside the water source is mostly wet.

Therefore, we have to find another way.

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

“Weaving baskets and baskets, focusing on closing.”

“Don’t be careless, otherwise, all previous efforts will be in vain…”

During the speech, Lu Yu had already returned to the house, carrying a bamboo basket on his back, and left the camp with great strides.

Prepare to try your luck in the forest first.

“Refractory clay is usually distributed around the water source, but there are exceptions. There are also a small amount of distribution in rock or coal strata.”

“A lot of people asked me why not go to the river?”

“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 unusable, it is best not to take this risk for foolproof.”

“Because there are more secure methods for us to choose.”

After walking into the jungle.

Lu Yu went round and round and found a rock vein splitting zone.

Along the weeds on the left bank, we moved forward.

While paying attention to the feet, I carefully observed the changes of the soil layer, and did not miss any clues.

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

The particles are larger.

The composition is relatively close to the original stone.

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

The fire resistance of virgin clay is stronger.

Also more competent for smelting operations.

After entering the Bronze Age.

In addition to fully mastering the methods of smelting metals, people have entered a completely new field for the application of other natural materials.

Clay is one of them.

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

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

Nowadays, in the ruins of many ancient civilizations found, the shadow of native clay can be seen more or less.

The reason.

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

…

Without direct sunlight and continuous heating.

The situation in the jungle finally improved.

The breeze hit.

A lot of refreshing.

Before the rainy season broke out, the final tranquility.

Carrying a bamboo basket.

Walked forward for a while.

The trend of the rock vein fault zone suddenly changed.

Immediately afterwards, a huge deep pit broke into sight without any reason.

Look over.

Deep pit fault is obvious.

It should have been formed by earthquakes, torrents, or changes in the island’s crust.

The roots of many trees can be seen crisscrossing in the pit.

Luo’s exposed soil layer is grayish white and looks very delicate.

It was the original clay Lu Yu was looking for.

“Look.”

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

“There is something we want inside.”

“The native clay contained in the rock strata is perfect mud.”

“With them, our molds have fallen, and find a way to get some up.”

The words fall.

Lu Yu did not hesitate at all, and immediately jumped.

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

I found a place with rich soil and took a look.

As a result, I don’t know.

Startled at first sight!

Lu Yu immediately frowned, and he laughed out loud.

This soil.

It is not ordinary native clay.

It is very rare kaolin!

You know, high-quality kaolin, whether it is fire resistance or adsorption, is the first to exist!

“Everyone, look at what I found…”

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

Put it under the lens.

“food?”

“Anchor, I don’t have enough books. Don’t lie to me. Isn’t this just ordinary dirt?”

“Looking at the small expression of Yushen, won’t you find something to eat again?”

“Eating dirt?”

“Lying trough, I see this kind of soil in Jingdezhen, what’s the name?”

“Feather **** don’t sell the key, quickly reveal the answer!”

After seeing the barrage, Lu Yu happily.

Full of joy:

“Brothers, this is not ordinary native clay.”

“It’s kaolin!”

“Kaolin is a very high-quality non-metallic mineral, mostly clay and clay rocks mainly composed of kaolinite clay minerals. Because it is white and delicate, we Chinese call it dolomite.”

“Kaolin is mostly dull, and when it is pure, it is white and delicate. If it contains impurities, it can have gray, yellow, brown and other colors. The appearance can be loose soil and dense rock depending on the cause…”

After briefly introducing two sentences, Lu Yu zoomed in again.

Patted the details of the clay in the palm.

Then he said:

“The kaolin here, look at this color, the purity is really visible.”

“Pure kaolin, white and delicate, is soft and soft, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite and quartz, Composed of minerals such as feldspar.”

“Kaolin is very versatile. It is mainly used in papermaking, ceramics and refractory materials. Using it to create pouring molds is perfect.”

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

It has a melting point of about 1785°C and is very fire resistant.

At the same time, it also has plasticity.

Wet soil can be shaped into various shapes without breaking, and can remain unchanged for a long time!

“Kaolin is highly respected in China and is named after Gaoling Village in Jingde Town, Jiangxi.”

“However, it is not unique to China.”

“In the natural world, it is widely distributed and has a large stock, almost 20 billion tons.”

“Among them, there is a kaolin deposit with a very high output in the Australian mainland, which is the closest to us, so it is not surprising to find kaolin here.”

Speaking room.

Lu Yu has unloaded the bamboo basket.

In one fell swoop the soil layer.

Packed up one after another.

Because it’s just a mold, it doesn’t need much anyway.

It is almost the same to get a half basket.

Instead of bringing it back to the camp, it is better to put it here and use it as you please.

It’s also convenient.

“Okay, brothers, it should be almost the same.”

“These soils are enough for us to create a perfect mold…”

Carrying the bamboo basket, Lu Yu stepped around in the pit.

Finally, he found a relatively low place, climbed up, and returned to the camp on the same path.

…

To the place.

Lu Yu put the clay aside first.

Turned around and turned out the wooden strip tile mold used to make the tile blank.

“This tile model can help us a lot, and the size is just right.”

“Otherwise, you have to do it again.”

Finished.

Lu Yu sat down beside the furnace.

Put the tile model on the stone board in the mud.

Afterwards, a large amount of kaolin was poured into it until it was completely filled and compacted.

With this clay model, you just need to sketch the desired shape on it.

“Because of the limited amount of copper material restored, it is basically hopeless to build a large jungle axe, but it is more than enough to have a Viking battle axe.”

Holding a stone knife.

Lu Yu carefully painted on the clay model while explaining to the audience:

“The Viking Tomahawk is the most commonly used weapon by Vikings.”

“In the cold weapon era, it was almost a manpower. It was improved from the commonly used logging axe. Its head is crescent-shaped, and it has great lethality when waving. It also has the effect of breaking the armor and shield. Let me talk.”

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

“And it’s easy to manipulate, far less clunky than people think. It’s a short and tough type. The requirements for materials are not so harsh. It should be our immediate choice…”

quickly.

Draw while talking.

It took less than five minutes.

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

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

This is also one of the characteristics of the Viking Tomahawk.

It is precisely because of such a design that Viking pirates can easily gather the lethality in a little while fighting with a battle axe.

It is very easy to break the protection of helmet and chain mail!

In fact, in the history of Northern Europe, you can often see the description of the Viking warrior splitting the enemy’s armor with a single axe.

“Okay, here, the model is basically ready.”

“Next, let’s go straight to the theme—”

then.

Lu Yu did not stop.

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

Hold the blower’s bow drill and push and pull it.

“Hoohoo!”

When the flame is big and small.

The firewood in the stove finally burned completely.

See you.

Lu Yu first put the pottery crucible with copper particles into the firewood pile.

Then, another round of charcoal was poured.

“After the fire burns, direct the charcoal.”

“Let the charcoal wrap the crucible. During this process, the crucible must be heated evenly, and the firepower should be increased as much as possible. Don’t be stingy with charcoal or your own strength -“

One sentence is not finished yet.

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

“Feather God!”

“Invincible hand speed!”

“Copper addiction + Kirin arm =?”

“Crazy output ing!”

“There are new materials in the Ghost Farm Area!”

“incredible……”

…

It took about ten minutes to operate.

Charcoal fire in the furnace.

More and more red.

The clay crucible has also undergone subtle changes.

Although it has not turned red, but from the structure of the surface of the clay, it seems that the temperature profile in the furnace has already reached the peak.

Looking at the situation in the furnace, Lu Yu did not stop, and poured a pile of charcoal into it.

“Maintaining furnace temperature is the key to smelting metals.”

“Be sure to add charcoal in time.”

“Don’t be in trouble.”

“Because once the temperature goes down, all previous efforts are in vain.”

Speaking room.

An hour passed.

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

The bottom of the crucible also has a very obvious reaction.

Unconsciously, it turned completely red.

The copper material inside seems to be melting bit by bit…

See here.

Lu Yu finally breathed a sigh of relief.

But the movement in his hand still did not stop.

Still holding the bow drill, she kept pushing and pulling.

“When the clay crucible turns completely red, the copper material inside will naturally become copper water.”

“But the process will be very long.”

“Even if everything goes well, it may take an hour.”

“During this time, we must be optimistic about the furnace temperature, if necessary, add charcoal in time…”

The words landed.

Lu Yu summoned the drone to his body, pushed it close to the camera, and took a picture of the fireworks.

The UAV of the system is made of special materials.

No fear of high temperature.

Even extreme violence can’t destroy it. Not to mention the fire of Baidu, even if it is found in the magma, it is a trivial matter.

Next second.

After the lens is zoomed in.

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

Call it magic!

“666666666666”

“Really melted!”

“Lying trough, great!”

“Is the Yushen drone too hard? Is it okay to reach into the fire?!”

“After all, local tyrants are exclusive!”

“It feels like drones are better!”

“233333333”

…

Soon~www.mtlnovel.com~ Another hour passed.

During the period, in addition to chatting with the audience one by one, Lu Yu added another piece of charcoal in the stove.

now.

The continuous high temperature finally burned the crucible red and red, very dazzling.

The copper in it seems to have turned into water.

See this scene.

Lu Yu wiped the sweat on his head and said:

“It’s almost the same to burn to this level.”

“Okay, next, let’s find something to clamp the crucible out, and then pour the copper water inside on the clay mold—”
