Chapter 491 Taking shape

[Wori…it’s **** shocking my mother for a hundred years]

[My mother asked me why I was kneeling to watch the live broadcast]

[Is this the GOD? 】

[So glucose is firewood, and carbon is charcoal, scratching your head? 】

[Dude, don’t you understand? In fact, I am too, shy]

[Yes, glucose is the firewood that needs to be boiled for water, and charcoal is the elemental carbon]

A simple one-pass analysis, the audience in the live broadcast room was shocked, and the barrage surged.

What’s more, it’s a big reward.

Emperor?

Is it a rare creature?

After thanking everyone for their support and rewards, Bi Fang continued to work. He piled up the clay to form a closed kiln.

“Charcoal is usually fired in two ways: pit firing and dry distillation.”

“The former builds a kiln with mud, fills it with wood, and then ignites and burns the wood to carbonize the wood in the kiln, volatiles escape and the remaining charcoal remains.”

“The dry distillation method is to place wood in a dry distillation kiln and heat it to decompose the charcoal under the condition of isolating the air. This is wood dry distillation.”

“The dry distillation method is based on the method of exiting the kiln. Generally, there are two types of black carbon and white carbon. However, we use the cellar burning method here, and all produced are black carbon.”

The piled up clay looked like a well, and Bi Fang poured a lot of wood into it, explaining:

“Don’t build the wood very well, because we need them to carry out the combustion reaction. If the wood is built tightly, it is very likely that charcoal cannot be formed inside.”

Then he inserted wooden strips around the “well” and moved closer to the middle like a tent to form a semicircle structure. With support, clay can be smeared on the semicircle to make a sealed lid. Next sip.

Bi Fang raised the torch and ignited the wood through the small hole reserved. When all the inside began to burn, and after thick smoke came out, he quickly pasted the last clay on the top to form an isolated environment from the outside world.

Under high temperature, the moist clay quickly dries and changes color, sealing the cellar firmly.

“Oxygen is isolated, and a high temperature and oxygen-depleted environment is formed inside. When the temperature subsides, we can harvest charcoal. If you barbecue in the wild, you can also make it with a tin pot and wood, but we need a larger amount, even if It’s the cellar burning method, and I may have to do it twice.”

Taking advantage of the wood turning into charcoal, Bi Fang once again came to the stove he was making now.

After a noon of drying and baking, the stove was completely formed, and the square cover on the side fell on the stove, even making a sound like cement colliding.

“Next, we are going to make the chimney. The chimney is built at the opening of the center of the circle here. The higher the better, but make sure the speed is not too fast. Wait until the next section of the chimney is dry before building the previous section, otherwise it will collapse. .”

Bi Fang picked the large frame of cement to his side and pushed the clay around the opening.

The whole process is very simple, no different from playing with clay in a kindergarten handicraft class, like building a castle on the beach.

“You should have seen chimneys. There are squares and rounds, but there are differences. Squares are easy to build, rounds pursue efficiency, and the smoke is evenly exhausted, and the wind resistance is small, so today’s large factory chimneys are generally Round, but homes are usually square for ease of construction.”

A straightedge is enough for a square building, but a round shape is far from simple and requires a lot of things. A little unevenness may also lead to easy collapse.

“So I chose to build a square chimney. The iron smelted here is far from the point where efficiency is required.”

Bi Fang piled up the clay squarely at the smoke outlet, and accumulated it little by little to the heights. The speed was not too fast, and the whole was very well-proportioned.

Every time a dozen centimeters are made, Bi Fang will use a relatively straight branch to measure it, and then continue to accumulate after confirming.

Soon, a half-person-high chimney appeared in front of everyone. Of course, this height was still not enough.

“Now let’s go see if the charcoal is ready.”

Bi Fang wiped the clay in his hand, came to the previously closed cellar, and reached out to touch the temperature of the wall.

Not hot.

“Wen, it should be almost the same. Let’s open it up and take a look.”

The clay dried at high temperature feels like cement, rough and hard, and it is not easy to open.

Bi Fang picked up the stone hammer on the side and slammed it on the dry and hard cellar. The well-proportioned cellar cover cracked and collapsed, several pieces of broken soil fell, and faint white smoke floated from the gap.

Breaking apart the lumpy, cement-like mud blocks, black charcoal appeared in front of everyone.

Bi Fang was not afraid of being hot, so he stretched out his hand and turned it over. It was warm, and all the wood underneath turned into black charcoal. Under the flip, the charcoal collided with each other, making a sound of gold and iron hitting.

[Fuck, I heard right? Why does it feel like black iron? 】

[Has Fang Shen already practiced iron? Secretly cast magic? 】

[Fantastic, I already said Fang Shen is an alien, you still don’t believe it]

Bi Fang picked up two long pieces of charcoal and blew the white ash on it: “This is black charcoal, commonly known as earth kiln charcoal. The surface is pure black or ash with white powder that can be blown off. The flaming charcoal is formed by cutting off the air in the kiln and extinguishing the fire.”

“The hardness of black charcoal is small, and it can be easily broken by pinching it. When it is tapped, it will make a hoarse sound, and its texture is soft.”

Bi Fang took out two pieces of black charcoal and tapped it lightly, and suddenly there was a dull metal knocking sound, and everything would shatter with force. For many people in big cities who had never seen it before, it was indeed very miraculous.

The product of burning wood actually emits a metallic sound!

He took out all the charcoal in the cellar and put it in the wooden frame, and Bi Fang put a lot of firewood in it.

Exactly the same operation, continue to cover the production.

“The charcoal in one cellar is theoretically enough, but to be on the safe side, I have to make another cellar.”

After finishing it, Bi Fang went back to the stove and continued to build up the chimney.

Gu Di By five o’clock in the afternoon, the charcoal was burned and the chimney was finished.

Bi Fang looked at the chimney that was more than two meters taller than his own, and was satisfied.

The chimney is square and straight, and the top section is even made of clay steps.

“I am 1.85 meters tall. As you can see, the chimney is half taller than me. It looks like two meters. It’s enough.” Go under the stove and start adding firewood.

After a while, white smoke began to rise from the tall chimney.

[You’re too long, you’re too long, it’s polluting the environment! 】

[What is this cigarette, it will degrade naturally. . . 】

[There’s not a lot of cars lined up yet]

【This is true】

[This chimney is too high, I feel like iron making is promising]

【The progress is very fast】

The audience ridiculed, but they didn’t pay much attention. Compared with the emissions produced by modern industry, Bi Fang’s amount of this amount was degraded by a few trees.

Under the setting sun, Bi Fang, who was smeared with red mud, was shining with golden light all over his body. He was wearing only a grass skirt and a necklace of animal teeth hung around his neck. He was wild.

Bi Fang wiped the sweat from his forehead, feeling a little tired.

Today, the workload of the day is not small. Not only has the blast furnace been built, but also a hill of charcoal has been piled up. Now my stomach is growling with hunger.

“I can start dealing with iron bacteria tomorrow, and maybe I can start iron smelting in the afternoon. When I went to pick up clay, I also cut two good branches, and I am going to build a bow and arrow tonight to see if I can hunt any pheasants tomorrow. Hare, improve the food.”

I eat fish every day, and many still have spines. Bi Fang is also tired of eating and tired of eating, especially today at noon, I was stuck by a fish bone, which is really uncomfortable. Fortunately, there was no major problem later, but now my throat is still a little sore. There is a sense of foreign body.

In the evening, Bi Fang cooked a pot of vegetable soup with stinky vegetables and fish and enjoyed dinner.

The water monitor lizard, which had been basking in the sun for a day on the slope, also began to come alive, hurried to the edge of the puddle, dragged two fish and left, one of which stood out quickly, accurately and ruthlessly.

Bi Fang noticed it, but didn’t bother to care.

Tired, so be it.

It is strange to say that as a cold-blooded animal, the water monitor lizard should not eat so frequently. Maybe it is because he is eating, so he is also hungry?

Or do you need food more during breeding?

Animals eat more simply and rudely than humans. The two fish shred and swallow them directly. The well-fed water monitor lizard spotted a big tree, used its sharp claws to slowly climb up, and lay motionless on the branch.

[By the way, can we see the birth of the little water monitor lizard before the end of the live broadcast? 】

[Impossible, didn’t Lao Fang say that eggs are born in June and July? How about a month or two? By then, Fang Shen will leave early]

[I checked just now, my dear, this thing can live to be one hundred and fifty years old]

[Wori? One hundred and five? Are you **** kidding me? 】

Seeing the audience discussing, Bi Fang thought about it and found that it was not impossible.

“It is normal to lay eggs in June and July, but in fact, water monitor lizards have the ability to lay eggs at any time, which is relatively rare in the animal kingdom, especially in areas lacking significant dry and wet season climate characteristics, water giants have the ability to lay eggs at any time. The lizards can spawn at any time of the year.”

“If this water monitor lizard is special and not born in June or July, then we might encounter the possibility of a baby monitor lizard being born.”

Bi Fang’s words gave the audience a great surprise.

[Damn it, can you really see it? 】

[Too arrogant, right? 】

[How does Lao Fang know everything? 】

Because I have seen breeding records of water monitor lizards.

Bi Fang complained in his heart~www.readmtl.com~ Every year, the Forestry Bureau releases water monitor lizards almost every year. So far, more than 300 have been released.

Although I haven’t seen it with my own eyes, I still know a little bit about it.

When the audience fantasized, Bi Fang, who was cutting wood and preparing to make bows and arrows, poured a basin of cold water again.

“Don’t think too much. The Banna rainforest has a distinct climate in the wet and dry seasons, so the possibility of production is not high in June and July, and the hatching time of this guy’s eggs is uncertain.”

“It is possible from two and a half months to 10 months or even longer, usually six months. Even if it is possible, it can be negligible.”

【Ah this】

[This guy is so ugly, how could anyone like him? scratching his head]

[plus one, I feel so ugly, this guy is setting up a nest not far away, I can’t count every day]

【I feel ugly and cute】

[The taste is too heavy! 】

Bi Fang smiled, the stone knife in his hand did not stop, and continued to cut the bow and arrow branches.

After all, a stone dagger is inconvenient. It would be nice if there was an iron dagger.

Looking at the sawdust under his feet, Bi Fang began to imagine the results in a few days.
