Chapter 26 Making a Stone Axe

Making a stove for burning charcoal is much simpler than making pottery, as long as the ground is surrounded by mud to form a circle.

There is no need to sift the soil, and it doesn't matter whether there is gravel or sand in the soil that will cause cracking, just enough moist soil is enough.

On the ground that has just rained, wet soil is everywhere, and it is within easy reach.

Soon, the first round stove with a height of sixty to seventy centimeters and a diameter of half a meter was built.

This is a stove for burning charcoal, and there is no need to cap it for the time being.

After putting in the wood during firing, put wooden branches on the top of the furnace and seal it with soil.

This kind of thing that can be done with hands has no technical content, but the large quantity consumes energy.

Because the embryo wall of the stove is a full five or six centimeters thick.

If it is too thin, it will not stand up at all, and it will collapse if it stands a little higher.

A large area of ​​soil was dug out, and a total of two charcoal-burning stoves and two iron-making kilns were built. The tired Won didn't want to do anything, just want to rest.

Iron-making kilns are slightly different from charcoal-burning furnaces.

The embryo wall of the kiln used for ironmaking is thicker, and although the diameter is similar, it is higher, so that it is convenient to store a large amount of charcoal and iron ore at one time, and it can better increase the central temperature.

Under the iron-making kiln, a circular hole was also dug, which was reserved for the installation of the blower at that time.

At the bottom of the charcoal-burning stove, there are four holes for ventilation to facilitate early-stage combustion.

Now that the kiln is built, the next thing to do is to collect wood.

But as soon as it went down, it was wet everywhere, and the work had to be postponed.

After finding a puddle to wash off the dirt on his hands, and sitting down to rest for a while, Han Yuan suddenly remembered the requirements in the system mission.

In addition to 30 days of survival in the wilderness, there are also requirements for building three stone tools.

After thinking about it, he felt that it would be better to get it done as early as possible, otherwise he was afraid that he would forget about it when the ironware was smelted in two days.

It just so happened that burning charcoal tomorrow will require a lot of wood, so he can make a stone ax to chop down trees.

While looking around for a suitable stone for a stone axe, he chatted with the audience in the live broadcast room.

"The furnace for making carbon and the kiln for making iron have been completed. Next, I will collect a lot of firewood to make charcoal."

"But before that, I need to build a stone axe, which can be temporarily used to cut down trees."

"Although the stone ax is also inefficient, it's still better than my bare hands."

Walking around, Han Yuan saw many stones, but after picking them up and looking at them, he shook his head and threw them away.

[I see that the host has picked up several stones, and there is also a stone ax that looks like a natural stone, which is not suitable? 】

[Is hematite ore not allowed?Iron-containing stones should be quite hard, right? 】

[This is about to enter the Iron Age, why not make stone axes, and then directly make iron axes? 】

[Where there is hematite, there are almost no stones that can be used to make stone axes. If you want to make stone axes, you have to find other places, preferably pebbles by the river, that is a good choice. 】

[? ? ? ?How do you know there is no suitable one upstairs? ? ? ? 】

[This can be judged from the hematite in the hands of the previous anchor. Those few pieces of hematite have metallic luster and fine scales, which are typical mica hematite. 】

[This kind of mica-type hematite is generally the product of sedimentary metamorphism, which also causes the stones near the mining area to be mainly mica, turquoise and argillaceous rocks, and some of these rocks are brittle although they are relatively hard. It shatters when touched hard. 】

[If you don't believe me, ask the anchor to find a random rock and try it out! 】

[I am a third-year student at China University of Geosciences. I am studying geology. I can't figure this out. How can I graduate? 】

[Fuck, it turned out to be the top student from the 985 school, sorry for your disrespect! 】

[Good guy, he pretended to be there! 】

[Is this also common sense? ? ? ? 】

I was also a little surprised to see the information Won on the barrage.

He didn't expect that the top students from the 985 school were watching his live broadcast.

Moreover, what this Xueba said was almost exactly the same as the knowledge information in the system novice gift pack in his mind, and it was even more detailed.

The information in his mind currently can only allow him to judge the type of stone, but he doesn't know what the conditions are, let alone what are the associated stones of hematite.

After all, this is no longer something contained in the basic wilderness knowledge information, but deeper geology.

He picked up a fist-sized stone from the ground and showed it to the audience in the live broadcast room.

"As the classmate said just now, this stone is a combination of argillaceous rock and ocher."

"Not only is it very brittle, it will be broken into pieces when it is hit with a little force, and the structure is very loose, with a lot of quartz sand mixed in it."

"Such a stone cannot be used to make a stone axe, it will shatter when touched."

"Look!"

As he spoke, he took the one in his hand and slammed it on a nearby tree with a 'snap'.

Let go of your hand, the fist-sized stone has been broken into three pieces, two pieces fell directly to the ground, and there is still a larger one in your hand.

And in the gaps between the fingers, there are also a lot of small gravel.

He threw away the stone in his hand, clapped his hands, and said, "As everyone has seen, this kind of stone cannot be used to make stone axes."

"The stone used to make the stone ax must be dense, not fragile, and able to withstand thousands of impacts."

"None of the stones around me are suitable, but I know where to find the right stones."

"The pebbles by the river are a very good choice, but I haven't found the river yet, but I have seen similar large quartz stones by the lake before."

"Like pebbles, the main component of quartz stone is also silicon dioxide. If you can find pure quartz stone, this is also a good choice."

Following the mark made before, Han Yuan walked towards the lake.

It was said to go to the lake to find suitable stones, but it didn't go that far at all.

After walking for more than half an hour, he found that he seemed to have left the hematite mine area, and the surrounding stone materials had also changed.

No, before he got to the lake, he saw a suitable stone on a gentle slope.

Han Yuan stepped forward and took pictures of the stones on the hillside for the audience in the live broadcast room.

"I'm really lucky. I don't even need to go to the lake. There are suitable stones on this hillside."

"These stones are all flint, which was already a good material for making various stone tools in the ancient primitive human period."

"Although the stone axes made of flint are much worse in toughness and impact resistance than those made of quartz stone and pebbles, they are easier to break and damage."

"But I'm just using it temporarily, so I don't have to worry about it so much."

"Moreover, the sharpness of the stone ax made of flint is much higher than that of quartz stone and pebbles, which allows me to cut down trees with less effort."
