The Rise of Primitive Tribes Farming

Chapter 311 The First Tinware

A tall furnace, made of clay, was built outside the pottery workshop.

In the middle of the bottom of the furnace, there is a ceramic disc with a mouth protruding from the outside of the furnace, which is where the tin flows out after liquefaction.

"Boss, can you just put this stone into the furnace?"

Wu Teng had never smelted metal before, and knew nothing about it, so he was very uncertain. He didn't even believe that the stone would turn into the shape of water as the leader said.

But he didn't know that Chen Bei had never smelted metal, he had only watched videos of similar iron smelting methods, and had no practical experience.

However, this is tin, which has an extremely low melting point, about 200 degrees, and it will start to melt, and the temperature is definitely enough to smelt it in a furnace.

Chen Bei said: "You put it in first, and try to burn it."

According to Wu Teng, he put the tin ore into the earth-built blast furnace, with a layer of coal on the bottom, a layer of crushed tin ore on top, and some limestone in it.

One end of the blast furnace is connected to a device similar to a hand-operated windmill.

Chenbei asked carpenters to make it in the shape of a windmill. It is similar to a blower. It looks very simple. It is a strange-looking windmill with a big belly. There is an air inlet at one end, but the air outlet is very slender and small. It is connected to the stove. .

After putting the tin ore in, Chen Bei rubbed his hands together nervously, and said, "Light it up!"

Wu Teng loaded a few pieces of burning coal with a stone shovel from the workshop, put them into the center of the furnace, and buried them in the coal.

"Blow!" Wu Teng said to the person in charge of blowing.

A craftsman in the pottery workshop began to shake the small windmill violently, and the coal burned violently in the stove, and the blue flame rose high.

Gradually, all the coals started to burn, and the inside of the stove was glowing red, and the temperature was very high.

Wu Teng used a long stone stick to poke it in from time to time to see if the tin ore had melted.

"Hey, it seems to have really melted."

Not long after, when Wu Teng pulled out the stone stick, he was surprised to find that there was a layer of silver-white liquid attached to the stone stick, which shone brightly under the light of the fire.

"let me see."

Chen Bei leaned over, took a closer look, and said with satisfaction: "Yes, this is molten tin, continue."

The melting point of tin is very low, and soon all the tin in the furnace will be melted.

After melting, it has the characteristics of a liquid and begins to flow from high to low. Impurities adhere to the coal and limestone, while relatively pure tin water flows to the bottom of the blast furnace and flows into the pottery circle. plate.

Then, through the long mouth of the disc, it flowed out of the blast furnace and fell into the clay pot.

"It's done!"

Looking at the silver-white tin water, Chen Bei was very excited.

People in the tribe may not understand what this thing means, but Chenbei knows very well that this is the first piece of metal smelted by the Mang tribe!
Utensils made of metal are not only beautiful and durable, but also can be recast. Most importantly, they can be produced in batches and quickly.

Tools made of high-quality stone are also very durable, but once they break, they are completely scrapped. Metal utensils are different. Even if a metal utensil is smashed into pieces, it can still be returned to the furnace for rebuilding.

In addition, each piece of stone tools requires a long time for stone tools to be polished, while metal tools only need to make molds and then pour them in batches, which is much more efficient than making stone tools.

Of course, whether it is stone tools or metal utensils, the best batches of them have their own advantages, and it is difficult to manufacture and takes a lot of time.

After all the tin water in the stove flowed out, Chen Bei got a pot full of tin water. He had made a rectangular mold with clay and sand. After the tin water flowed out, he directly poured it into it with his bare hands. mold inside.

The tin water gradually cooled down in the mold, and finally turned into a tin ingot.

"Ding!"

Chen Bei poured the tin ingot out of the sand mold and knocked off some of the sand on it. The tin ingot was heavy to the touch and much brighter than the raw ore.

The raw ore is dark silvery white, but the refined tin ingot is bright silvery white. Although the surface is a little rough, in Chen Bei's eyes, he likes it no matter how he looks at it.

Wu Teng came over, carefully observed the tin ingot, and then said to Chen Bei: "Boss, what is this thing used for? Can it be used as a weapon?"

Chen Bei shook his head and said, "No, tin is too soft and cannot be directly used to make weapons, unless it is refined into a hard alloy by adding other metals."

"Alloy?" Wu Teng scratched his head, what Chen Bei said was beyond his cognition, he couldn't understand these words.

Chen Bei didn't expect him to understand, he took the tin ingot and looked at it over and over again, saying: "Let's use this tin ingot to make the simplest tin bowl first."

Wu Teng looked at the tin ingot, made a gesture, and said, "Boss, what should I do? Find a stone tool master to polish it?"

Chen Bei shook his head and said, "Crush it again, put it in a clay pot, and melt it."

"Huh? Melted again?"

Wu Teng and the craftsmen of the pottery workshop were all dumbfounded. They just melted tin ore into tin water, then cooled it to get this tin ingot, and now they have to melt it again. Isn’t this unnecessary?

Chen Bei didn't explain that much to them, anyway, he will understand after doing a lot in the future, so there is no need to say more.

As a leader, that's all it takes. What he says, the people below must do. Even if they have doubts, they don't dare to say more.

Chen Bei also made a model of a bowl with clay and sand, making it very round, and then brought a real pottery bowl and smoothed the bottom.

Then, Chen Bei broke the tin ingot into pieces with his bare hands, put them into a refractory clay pot, and put it on the stove.

"Huhuhu..."

The craftsman in charge of blowing the wind turned the windmill quickly, and the fire burned violently, slowly burning the clay pots red.

The tin in the pot was melted again into tin water.

Chen Bei used two thumb-thick stone sticks to easily clamp the clay pot out of the fire, and then poured the tin water in the pot into the sand mold he had made.

Finally, he put the bowl with the flattened bottom into the sand mold, and pressed the tin water to overflow.

The pottery bowl is smaller than the sand mold, and there is a gap of about one centimeter between the two.

This gap is just filled with tin water, and the excess tin water is skimmed aside.

Soon, the tin water gradually cooled down.

Chen Bei took the pottery bowl away, and saw a very rough tin bowl lying in the sand mold.

It is not only rough, but also very thick. This is also because it is the first time to make it and there is no experience. After slowly improving the pouring mold, it will definitely be beautiful in the end.

Chen Bei picked up the tin bowl, cleaned the sand on it, and then found a rough stone to polish it finely.

After an hour of polishing, the surface of the tin bowl became smoother, and it no longer looked so ugly. It shone with silver-white metal, which made Chen Bei feel particularly fulfilled.

"This is the first tinware of our Mang tribe, and I will use it to eat from now on!"

Chen Bei raised the tin bowl high so that everyone could see it. The surrounding clansmen were a little confused, but they cheered in unison.
