From Chief to Ball

The key to smelting is to smelt the slag well. The slag is not smelted well, the metal and the slag are not separated, and the blister copper has too many impurities, and in that case the shaft furnace is disposable, and the furnace can only be smashed to take out the slag.

After loading the ore materials, Chen Jian still prayed silently. This is his first metal smelting in this world, and he prayed for a success.

The first wisp of blue smoke from the copper furnace came out, and the people in charge of pulling the bellows on both sides began to work hard, pumping the simple leather bellows vigorously, sweating profusely from exhaustion, and some smoke came out from the flue on the top of the furnace. I caught a dodo bird and let it stay in the smoke for a while, and I was relieved when I found that it was not dead.

Some copper ores will be fused with arsenic, and that kind of smoke will kill people. It seems that I am lucky, there is no such poisonous thing in these copper ores.

Looking at the clansmen who were taking turns pulling the bellows, Chen Jian encouraged: "Keep working hard. After you know how to smelt, you can sit down and let the slaves do it. You just need to be responsible for watching with your eyes."

After breathing for a long time, the color of the smoke in the upper flue gradually faded, and the temperature in the furnace should be very high.

Chen Jian opened the observation hole near the tuyere and took a look. The ore inside had melted, but there was only one layer at the bottom, because there was not much ore added when loading the material, mainly charcoal.

Another part of the material was added. The copper content in the mineral material is not high, and the slag must be more than copper.When the slag was about to approach the observation hole, the slag discharge hole was opened.

The melted slag was sticky, and the clansmen were shocked to see the stones melted by the fire, and were amazed.

The fluidity of the slag is not bad, at least for the first smelting, this is extremely rare.

After the slag is discharged, immediately block the slag discharge port with the prepared wooden sticks and some charcoal ash to maintain the temperature in the furnace.

This is just the beginning. Chen Jian estimated the level of charging, and there is only about ten catties of copper in the furnace. The amount is too small, and he has to keep adding materials.

The person who pulls the bellows has changed six or seven waves, and a lot of slag has been discharged, and finally it is time to produce copper.

Chen Jian rubbed his hands. In such a cold day, his palms were already covered with sweat, and his heart was pounding.

According to what he said, the two tribesmen had already waited until the copper hole came out, and prepared the clay pots.

When they counted to three, two people picked up wooden sticks and poked open the copper hole vigorously. The molten copper juice immediately flowed into the jar obediently, and immediately replaced it when it was full.

After the copper juice is almost flowing, close the outlet and continue to add materials. Now it seems that the smelting is still successful. The two blowers provide enough oxygen, and there is no insufficient combustion and insufficient temperature.

The copper did not flow out completely, because the copper outlet hole was higher, and the remaining copper juice could maintain the temperature in the furnace, which was convenient for continuous smelting.

As long as the smelting starts, it is best not to stop the furnace unless there are too many impurities in the furnace to continue smelting.But now there is not much mineral material, and it is impossible for these people to keep running without sleeping, so they had to add some charcoal to maintain the high temperature in the furnace, and discharge all the slag to prepare for shutting down the furnace.

After the copper juice cooled down, the clansmen looked at the two large jars and felt that they were very heavy when they lifted them up.

I broke the jar and took out the copper block formed inside. The color is not bad, and the copper content should not be low.

Chen Jian caressed the two pieces of thick copper, because the shape of the pot was small at the top and big at the bottom. Then he looked at the copper stove that looked like a goat's milk bag, and he seemed to suddenly understand why copper was called gold in ancient times, and why copper was called gold in ancient times. Why did Kim write that again.

Jin, doesn't it look like a copper smelting furnace?

Copper was supposed to be the earliest metal to be smelted, so it would naturally be associated with things like copper furnaces and crucibles. It is estimated that the clansmen would easily accept this word when it was coined.

He drew a character that looked like gold on the ground. The people who participated in the smelting recognized it as a copper furnace at first sight. People were standing on the copper furnace to add materials...

The pronunciation of this word is based on the original sound. It is a word describing a purple-yellow color.

At least, when describing the sunset in the future, the clansmen added another adjective—golden sunset.

This gold is metal gold and is no longer stone.

Chapter 43 Only sleep with me, okay?

At last the coldest days were over, as if the rising flames of the furnace had driven away the wind, the sun was getting higher and higher every day, and the nights were no longer so long.

For more than ten days after the successful copper smelting, Chen Jian has been kneading beeswax in the house.

The beeswax accumulated during the warm period finally came in handy. There are no ash poles and ash worms here, and beeswax is the only source of wax.

The old grandmother had already made a model of the child out of clay. After Yu Qianer saw the little clay child, she was terrified for several days. She couldn't figure out how it was born. She always wanted to ask those cousins ​​and aunts, but It didn't feel good again, since she put on the clothes, she seemed to understand what happened to the body covered by the clothes, it's best not to ask others.

Those people were about to give birth in a month or two, and Chen Jian was also busy making wax models of forceps.The forceps can just hold the baby's head, which can be easily dragged out by the midwife. It may cause irreversible cranial damage to the baby, but it is not considered for the time being.When a person is about to die of starvation, it is hypocritical of a bitch to think that eating too many steamed buns may choke to death.

The child is very small, and the whole forceps don’t need to be too big, just enough to hold the child’s head, which is just the limit of the tribe’s casting of bronze today, and longer daggers and the like require technical accumulation. Bronze swords If it is not long, it will break.

He made this wax model for four whole days before it was considered a prototype. It seemed that the first forceps would be too bulky.Chen Jian looked at this simple wax model of obstetric forceps, and said to himself, let’s not talk about anything else, at least there should be no story about Zheng Boke and Duan Yuyan in the history of this world, because his mother would not hate difficult labor and prefer normal labor younger brother.

The flapping of the butterfly's wings only exists in his brain, because it will never happen at all, but he did not expect that the wings in reality have already started flapping.

In a hut, Yu Qian'er was chatting with Lancao, and the two were winding twine.These days the people of the Tian clan spin much faster. The captured woman doesn't need to spin these days, she just needs to tell them how to spin fast, and there are fish to eat every day.

Just as they were about to talk about having a baby, the straw curtain was opened and the civet cat walked in.After seeing Yuqian'er, he smiled and took out a very small stone and shook it in front of her eyes.

Yuqian'er's eyes were immediately attracted by the small stone, which was an irregular piece, only the size of a fingernail, and was blue-green in color.

It's a little cloudy, and it looks very beautiful, just like the feathers of some waterfowls, it's not transparent, and there are still traces of smashing in many places.

The civet cat waved one in front of Yuqian'er's eyes and said, "Do you want it?"

"think."

"Then you go out, I want to talk to your sister Lancao."

"it is good."

Yu Qian'er took the stone, wrapped a beast's tail around her neck to block the cold wind around her neck, pushed aside the grass curtain and stood outside the house, put the small stone in the snow, and watched the sun shine on it .

But the ears stretched out long, like a little rabbit, she wanted to know how the stone came from.

In the house, the civet cat took out several similar small stones, Lancao put down the thread in his hand, and grabbed these slippery stones happily.Women are always the same as those birds who love to dress up, unable to resist the temptation of this kind of brilliance.

"Isn't it pretty? In a few days, I'll give you a hairpin with gold and decorate it with these stones. It must be pretty."

"Where did it come from?"

"Isn't it alchemy a few days ago? I found it from those slags, shining in the sun."

"Didn't brother say what this is?"

"It seems that this is slag glaze? That's probably what he said. He named it casually. It's rare. He said it couldn't be refined. It's like a deer running into a clay pot by itself. It's very difficult to find it from the slag. .This thing is all mixed with slag, and there are only a few of them. I hit them with a stone. It is so sharp that my hands were scratched."

He raised his hand and showed Lancao the wound.Lancao said distressedly: "You go to Song to get some herbal medicine, but don't hurt too much, he can't do any work now, and he can't hold the bone weapon anymore, so you have to be careful."

The civet cat nodded, first put his hands in his arms to warm them up, and then stroked Lancao's belly, lying on it and listening to the child's movements, he laughed.

Lancao looked at this man who was quick to do everything except digging, and felt warm in his heart. He was one of the three people he liked, and he was also the one who often gave himself some good things or played the bone flute for himself.

Originally, the three of them were all the same, but now she seems to like this man a little more, because she likes to see the way this man is praised when he builds kangs for other tribes, and also likes him leading thirty people in the snow by the river. The cry of the ground charge.

Everyone used to be pretty much the same, but since the Jian Rang tribe changed, people have gradually become different, and being strong is no longer the only criterion for choosing a mate.

After a long time, the civet cat raised its body, put Lancao on its lap, helped her hold her hair, and suddenly said loudly: "Lancao, will you only sleep with me from now on? I won't sleep with other women either."

Lancao was stunned for a moment, and the civet cat sighed: "When I see those two people also give you something, my heart hurts, like drinking a whole jar of health-brewed apricot vinegar. The bee stung my heart. I haven't slept with another woman for a long time, and I only want to sleep with you from now on."
