…

Two hours later.

Lu Yu put the finished blower aside.

I walked to the charcoal kiln and leaned over to observe the fire inside through the ventilation holes below.

At this time, the fire above had completely spread to the bottom of the kiln.

The firewood below was bright red.

"Everyone, it's almost done after it's burned like this..."

Pulling out a large piece of clay from the bamboo basket, Lu Yu continued:

"The next step is to plug all the vents with mud."

"Including the opening above the kiln roof."

"The purpose of this is to slow down the burning speed of the charcoal and allow it to be completely carbonized. By then, as long as all the volatile gases have escaped, you will be done."

"The whole process may take some time, so we still have to wait for a while."

Taking advantage of this time, Lu Yu ate something casually to replenish his energy.

Then he ordered the stove to be started.

A fire was rearranged.

And take out most of the remaining mud.

Around the fire.

A small cylindrical furnace was built round and round.

"Someone asked in the barrage, why do we need to build another furnace when we already have an earthen kiln?"

After looking at the barrage, Lu Yu explained:

"Actually, it's very simple. Bigger is not always better."

"For smelting metals, a small furnace is easier to concentrate the temperature than an earth kiln. Secondly, because we have limited materials, if we use an earth kiln, more charcoal will be wasted, so it is necessary to build a separate small furnace."

While talking.

Lu Yu first smoothed the edge of the furnace with his hands.

Then a moderately sized charcoal outlet and air inlet were opened at the bottom.

The role of the air inlet is obvious.

Just to connect the hair dryer of the blower!

The function of the charcoal outlet is also easy to understand.

With it.

After the refining is completed, the copper material reduced by charcoal fire and high temperature can be easily retrieved from the furnace.

It has much the same function as the charcoal kiln door opening line.

…

Live broadcast here.

With the blower, furnace, ore powder and charcoal, the preliminary preparation work is basically complete.

Next.

As soon as the charcoal comes out of the oven.

Just throw the ore powder into the furnace.

Covered with charcoal and smelted.

By the time.

After continuous refining at high temperatures, the copper contained in the ore powder will naturally be gradually restored and turned into copper material.

After that, just melt the copper material into liquid copper.

Pour into molds.

You can turn it into the shape you want!

Like an ax blade, a knife blade.

Even arrowheads are no longer a problem.

…

Time flies.

It was two o'clock in the afternoon in a blink of an eye.

Wait for the charcoal to come out of the oven.

Lu Yu was not idle either.

He kept chatting with the audience word by word.

It wasn't until the green smoke at the entrance of the charcoal kiln stopped evaporating that he stood up and walked over to check.

Arrived at the kiln.

He first felt the temperature of the kiln wall with his hand.

Then, he checked the fire on the top of the kiln.

After a while, he said:

"Friends, the fever should be almost over."

"Without any further ado, let's open it first and see what's going on inside -"

After five hours of firing and cooling, the fire in the kiln has been completely extinguished.

Not even a single spark can be seen.

After the pyrolysis of the firewood, a strong smell of charcoal came over with overwhelming force.

Say it.

Lu Yu casually picked up a small wooden stick from the ground.

Along the gully of the goal line, there was constant beating.

Not much longer.

The hard soil inside the goal line suddenly collapsed.

A dark mass emerged from inside.

Steam and smoke are constantly rising.

See this.

Lu Yu felt happy and hurriedly zoomed in on the camera to take a closer look.

"Brothers, look -"

At this moment, the originally gray-white eucalyptus branches had already turned into fragmented charcoal blocks after incomplete combustion.

After gently picking them up with a wooden stick, they all rolled down.

This amorphous charcoal not only fully maintains the original structure of the wood.

There is also a lot of tar remaining in the pores.

At the end of primitive society, it was this amorphous charcoal that people used when smelting bronze and iron.

With this thing, smelting copper by fire will be much more convenient!

As long as you control the temperature and restore the copper material, it shouldn't be a problem!

"6666!"

"Really turned into charcoal!?"

"I'm getting better!"

“BBQ is ready!”

“Thousands of miles away from Jiangling, I also gave the anchor 666×10 as a gift in one day!——It’s quite interesting!”

"If I don't practice immortality for a day, I will feel uncomfortable. I will give the host a plane x 1! - Damn it! The host is really awesome!"

"Ride the bike to 80 miles and give the master super rocket x 1 as a gift! - Convinced!"

Talking.

Lu Yu casually picked up a piece of charcoal with good integrity and showed it to the audience:

"Looks pretty good."

"This amorphous charcoal can not only provide high temperature, but also be a great reducing agent. If it is used for heating and grilling food in cold areas, it is also a good choice."

"These charcoals should be enough for us to use for a long time. Even if it is not enough, it doesn't matter. If necessary, we can just burn a kiln again. The method is also very simple. Just like before, pile up the firewood first, and then use mud to block the door line. As long as the door line is still there, the charcoal kiln can be used repeatedly, which is very convenient."

As Lu Yu spoke, he used a wooden stick to take out the charcoal in the kiln and put it aside for use.

When he returned to the furnace again, he first added some firewood to the fire to maintain the fire.

When the fire was almost burned, he spoke:

"Okay, everyone, everything is ready."

"Let's start-"

"First, lay a layer of charcoal as the base. After the charcoal is completely red, you can directly put the mineral powder. No container is needed, just throw it into the fire and burn it."
