The Ultimate Live Superstar

"Support, come on!"

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

The barrage suddenly increased.

It took a long time to calm down.

After calming everyone's emotions, Lu Yu continued:

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

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

"Next, as long as we follow the steps and melt these copper materials, we will basically be done. However, before we officially start, there is one thing that we need to spend some time thinking about, that is, mold making."

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

"Therefore, making molds is also one of the indispensable links."

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

For example, platinum, quartz, and silicon carbide.

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

Even if they can be obtained, there are no related tools to turn them into molds suitable for themselves.

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

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

Using clay to make molds is also an ancient casting method.

It is convenient and easy to obtain.

The molding rate is also considerable.

The production process is not as complicated as imagined.

It is nothing more than using a sharp tool to carve out the type of mold you want on the flattened clay.

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

It's not difficult.

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

It is best to use high-quality dry clay.

Clay with a high water content is not competent.

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

So, we have to find another way.

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

"The key to making baskets is the closing."

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

As he spoke, Lu Yu had returned to the house, put on the bamboo basket, and strode out of the camp.

Prepare to try your luck in the woods first.

"Refractory clay is usually distributed around water sources, but there are exceptions. There is also a small amount distributed in rock or coal formations."

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

"The fundamental reason is that the soil with too much water content is not easy to pour, and 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 for the sake of safety."

"Because there are more reliable methods for us to choose."

After entering the jungle.

Lu Yu wandered around and found a dyke split zone.

Along the weed-covered gully on the left bank, he moved forward all the way.

While paying attention to the ground, I carefully observed the changes in the soil layer, not missing any clues.

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

The particles are larger.

The composition is also closer to the original stone.

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

The fire resistance of primary clay is stronger.

It is also more competent for smelting operations.

After entering the Bronze Age.

In addition to fully mastering the method of smelting metals, people have also entered a 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, primary clay naturally became their favorite object.

Nowadays, in many of the remains of ancient civilizations that have been discovered, the shadow of primary 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 has finally improved.

A breeze blew.

It was much fresher.

It set off the last tranquility before the rainy season broke out completely.

Carrying a bamboo basket.

Walked forward for a while.

The trend of the rock vein fault zone suddenly changed.

And then, a huge deep earth pit suddenly came into view.

Bending over to check.

The deep pit fault is obvious.

It should be formed by earthquakes, mountain torrents, or crustal movement on the island.

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

The exposed soil layer is grayish white and looks very delicate.

It is the original clay that Lu Yu is looking for.

"Look."

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

"There is something we want in it."

"The original clay contained in the rock strata is a very perfect soil."

"With them, our molds are settled. Think of a way to get some up."

After that,

Lu Yu jumped without hesitation.

He came to the bottom of the pit from the edge.

He found a place with rich soil and looked around.

The result was unpredictable.

He was shocked when he saw it!

Lu Yu was so happy that he almost laughed out loud.

This kind of soil.

It is not ordinary native clay.

It is very rare kaolin!

You know, high-quality kaolin is second to none in terms of both fire resistance and adsorption!

"Everyone, look at what I found..."

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

He put it under the camera.

"Eat?"

"Host, I don't have much education, don't lie to me, isn't this just ordinary soil?"

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

"Eat soil?"

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

"Yu Shen, don't keep us in suspense, reveal the answer quickly!"

Looking at the barrage, Lu Yu laughed.

Full of joy:

"Brothers, this is not ordinary native clay."

"It's kaolin!"
