Chapter 93: Casting in Progress (1)

Green Tuanzi, can you sense the location of the iron mines around the tribe?"

Although Nuan Nuan has some broken iron that has been refined earlier, it is far from enough to be here.

Green Tuanzi followed behind her, "Mother, magnetite ore and hematite are very widely spread, and there are many iron ores distributed within the tribe, and there are several ore mountains surrounding the tribe! ”

Nuan Nuan was very surprised when she heard this, and instantly looked up at the towering cliff and stone wall surrounding the tribe, "Great! Let's go over and have a look!"

Thinking of the training camp under the city wall in the south of the tribe and the medicine garden in the south, Nuan Nuan went straight to the cliff in the north of the tribe, she really didn't study the ore deeply, she could only identify gold, silver, copper and iron, but this was also very good.

She had never looked closely at the cliff, but if she looked closely, there was indeed a lot of iron ore and copper ore on the cliff!

Nowadays there are caves of all sizes, all of which were originally inhabited by the people, but now that they have moved, many of them are empty.

"Let's go inside!"

Walking into one of the caves, it was still very dry, and the warm eyes were fixed on the cave walls.

The walls of the cave are uneven, and the rocks are protruding wantonly.

I'll go!

It looks like it's all copper ore rough!

Walking a little further inside, Nuan Nuan found a large piece of iron ore on the cave wall!

"That's great!"

There are treasures under my nose!

Nuan Nuan really regrets not finding out earlier!

Walking out of this small cave, Nuan Nuan turned to another big cave not far away.

She was pleasantly surprised to find that there were pieces of pure black ore and coal mines!!

Nuan Nuan Le is stupid!

It's a coal mine! I just don't know if it's much.

"Green Tuanzi! Look! This 、、、 this, this is a coal mine, right?!"

Green Tuanzi nodded, "Well, this is coal mine, but there are not many on the surface of the tribe here, most of them are very deep underneath. ”

That's nice too!

This large cave is the largest of the currently vacant caves.

At the entrance of the cave, Nuan Nuan raised her hand to condense her spiritual power, and the surroundings were filled with strong earth spirit elements, because she had experience in smelting iron, and was now able to cast magic, so she easily built three huge improved pit high-temperature ventilation furnaces and two small ones.

"Patriarch ——"

"Uncle Chuan, Abba, why are you here?"

"Hey girl, it's nothing big for us to find you, it's just that I'm greedy and want to ask you for some sweet fruit wine. ”

Nuan Nuan smiled sweetly, "I've finished drinking the wine I gave you?" Okay, I'll go and make more wine for you when I'm done." ”

"Huh, girl, what's this?"

Ray curiously touched the towering dirt furnace.

Nuan Nuan smiled even sweeter, "Abba, Uncle Chuan! This is my self-made pit high-temperature ventilation furnace."

You see, our tribe is full of treasures!

Many of the ores on these cliffs can be extracted from fire to make metals, which can be used to make a wide variety of weapons and tools. ”

"Oh my God!

The two middle-aged uncles were shocked, and they did not doubt the authenticity of Nuan Nuan's words at all.

Looking at them, Nuan Nuan calmed down.

Although she knows magic and can easily get these ores down, it is only for what she can see.

What's more, this tribe is not her alone, so mining ore must be done by the tribe's clansmen, and she doesn't know what will happen in the future, after all, she is not a person.

It's better to teach people to fish than to teach them to fish, it's not that she doesn't understand this.

In that case, she had to make a set of tools for mining stones.

Mining tools, pickaxes and hammers.

It's really hard for her, and she needs to do some preparation.

First of all, he ordered a large amount of charcoal to be brought in a wooden cart and stacked neatly in a corner of the big cave.

She took the opportunity to go back to her home, and took a large number of iron beads and pieces of broken iron that had been refined during the harvesting period, and such a large amount should be more than enough to make a set.

The most important preparation is to make the crucible.

The crucible is the most commonly used vessel for melting and refining metal liquids and solids for heating and reacting in human civilization.

Middle school chemistry has been taught for a long time, and Nuan Nuan is glad that she hasn't had time to return it to the teacher, thanksgiving~~

The materials used to make the crucible were warm and warm, but she knew that it had to be very fire-resistant, and what could be more resistant to fire than clay at hand?

Under the eager gaze of the two elders of Lei Chuan, Nuan Nuan took a pile of clay and began to shape it with water.

Clay is much more malleable than ordinary clay, and most importantly, it is very resistant to fire and does not crack easily.

In the valley, there is not much else, but the most clay, so to speak, is everywhere, and the high-temperature furnaces are made of clay.

Nuan Nuan hand-pinched a clay jar with a thickness of about 20 centimeters, then opened the lid on the small high-temperature furnace grille, and carefully placed the clay jar in the middle of the grille.

Surrounded by burned red charcoal, she couldn't stand the scorching flames for a while,

A gust of wind blew into the cave, and the flames suddenly rose high, so frightened that she hurriedly retreated, and then laughed.

There are three reasons why the furnace was set at the mouth of the big cave,

First, resist the possible rain and snow;

Second, the ventilation effect is very good, the vent is facing the outside, and the air outlet is also smooth and will not let the cave smoke;

Third, it is convenient to take local materials and avoid long-distance ore transportation.

It didn't take long for the clay jar to burn red, and it seemed like it was time.

Nuan Nuan carefully threw all the broken iron into the simple original crucible, then added some new charcoal around the crucible, and finally covered the earth lid, and began to slowly burn the molten iron.

The biggest advantage of this kind of furnace is that it does not need to be manually blown, which is very labor-saving, you only need to watch the fire, and regularly clean the carbon slag that falls down at the air inlet and under the grille to prevent the air inlet from being blocked.

Waiting for the process of metal melting, Nuan Nuan continued to do the equally important thing, which is to make molds!

The handle is made of wooden sticks, which can be ignored for now, and Nuan Nuan is first cut into a pickaxe model with wood;

A pickaxe is sharp at one end and flattened at the other, forming a slightly curved arc.

The middle hollow forms a cylindrical shape for the wooden rod to be fixed in, and when cutting the model, Nuan Nuan deliberately controls the thickness of the joint to prevent it from breaking after molding.

The spirit is highly concentrated, the finished product is naturally not inferior, and the finished model looks very delicate and sharp. Next is the hammer model, which is much easier, as long as you grasp the connection of the hollow part in the middle.

Build a deep wooden trough, cover it with dirt, place the mold on it and press it down until it's just submerged;

Then carefully tamp and press the surrounding soil, and then carefully take out the mold to prevent the soil from loosening.

The hollow area is carefully padded with wide leaves, and then covered with thick soil to ensure the hollowness of the inside of the mold;

Finally, the mold is compacted with a flat stone,

After thinking about it, Nuan Nuan casually sharpened a wooden chisel, which can be used with a hammer, and carefully inserted the wooden chisel into it and then pulled it out.

The handle Nuan Nuan chose two cooked wooden sticks, which are very strong, and when cutting the wooden model, Nuan Nuan will cut the wooden handle at the same time, and everything is ready.

Seeing this, Lei Hechuan was still confused, he didn't know what Nuan Nuan planned to do, and he didn't dare to disturb him, so he could only continue to look down.

After cleaning out the carbon slag for the fifth time, I opened the soil lid and saw that the broken iron had finally melted!

With an excited heart, Nuan Nuan took the hard bamboo strips that had been prepared a long time ago, and carefully clamped the clay crucible steadily, and then slowly clamped it out of the red charcoal and put it on the ground;

Clamp it firmly again, slowly move to the deep wood groove mold next to it, and then put it down;

Nuan Nuan is very cautious, the temperature of this thing is more than 1,500 degrees, and if you accidentally touch it, you can't even save your bones.

Clamped it up steadily, slowed down his breathing, and tilted the crucible slowly, the silver-brown molten iron was like a silk trickle, and the water vapor splashed everywhere, making a sizzling sound.

A small amount of molten iron spilled out of the small opening, but most of it entered through the small opening, and after the small opening of the chisel was cast, the molten iron was just used up.

After waiting for a while, the molten iron has gradually cooled and hardened.

Nuan Nuan pulls the soil in the trough with bamboo chips, and the chisel is very good, straight and straight,

The bottom is flat and sharp, and the top is just condensed into an irregular but not small striking surface because of the overflow of molten iron, which can be used by the hammer to beat without worrying about hurting your hands!

The hammer is also very good and of great quality;

The most anticipated thing is the pickaxe, Nuan Nuan pulled down, and finally dug the pickaxe body;

Pick out the dirt, warm eyes light up, it's really good!

But after all, there are a lot of blanks, and they still need to be reprocessed.

Nuan Nuan smiled and put the finished product in the cold water on the side, and suddenly the water surface made a sound, it was really not ordinary hot!
