Chapter 495 Earth OL Iron Age
2Fe2O3＋3C will generate 4Fe＋3CO2 under high temperature environment.
This equation is the key to Bifang iron making. At the same time, the sulfur in wood ash can accelerate the liquefaction of metal and reduce the temperature required for iron smelting.
High temperature and charcoal raise the temperature, while wood ash lowers the required temperature. Only when these two combinations are used together can qualified iron be successfully produced.
【WHAT THE ＊＊！ 】
【Why can’t I understand it at all? 】
If domestic audiences can still understand it, foreign audiences are already confused.
How come I have never heard of these things?
Have you really been to school?
Why do I feel like I've never learned anything?
【Huaxia’s education is horrible! 】
[I remember we taught this before, but you didn’t listen carefully in class…]
【I went to play basketball. 】
[I might be in love]
Mix all three kinds of ashes together, add water and mix, then roll it into a flat and round shape.
After making a clay cake, Bifang said, "We are not doing an experiment, so there is no need to make the proportions so clear. As long as it is roughly one to one, three in one will make one."
[This is the DLC of Earth OL, the Iron Age! ]
[I’m so excited! There will be iron ingots soon, and soon there will be a small iron sword.]
[I bet 50 cents that after refining, there will definitely be a rich man who will buy it at a high price! ]
The audience all fantasizes about being the lucky one, but if you think about it, you will know that it is basically impossible.
Damn, they want it too!
[Lord Mu is rubbing his hands in anticipation. I want this discus! ]
[And there is General Lin, who is he looking down on? Let’s fight, let’s fight]
[Mr. Lin doesn’t seem to watch live broadcasts very often, Mr. Yao seems to have more free time]
[I'll offer 10 million! If Fang Shen agrees, then just ignore what I said]
After rubbing and rolling, another black cylinder appeared.
This was the third piece. Bifang put it aside to dry. It was already noon.
Today's weather is very hot and humid. Bifang wiped the sweat from his forehead with his arm: "It's time to eat, but let's make the pottery first."
At this time, the small pots on the ground were all dried under direct sunlight. Bifang removed the stove stone slab, placed it on the stove bridge, spread wood around it, lit it, poured in a large amount of black charcoal, and covered it with a lid.
How long will this burn?
[Should be soon? ]
[No, I remember that it takes a whole day to make a purple clay teapot?]
Bifang estimated that it would take a long time, but definitely not as long as a purple clay teapot.
What he made was low-temperature pottery, which could be fired in about three to four hours and would definitely be ready before dinner. I could try the meat in a pot today.
"It seems that two pits of charcoal are not enough. We need to burn another pit later."
Bifang looked up at the sky. Today's weather was too hot. The trees in the rainforest were tall, blocking the sky, making it difficult to judge the weather.
"It looks like it's going to rain again?"
The drone camera moved upwards, and everyone saw that the originally clear and cloudless sky had become gloomy again.
The audience was speechless. How could the rain come just like that?
[No way, it's raining again? ]
[Are you kidding me? It rained for five or six days on the 11th? It rained half the time? ]
[Will it affect pottery making? ]
Bifang nodded, but then shook his head and said, "There will be some impact, but not a big one. After all, it is the rainy season. I prepared for this situation when I built the blast furnace. The entire shelter and blast furnace were built on high ground."
The shelter has a wall. Although the bottom of the blast furnace is underneath, the overall terrain is high. If the rain is not heavy, the impact of the rain falling in that one square meter will not be significant.
The pottery jar was not yet prepared, so Bifang still had fish, vegetables, and two grilled chicken wings for lunch.
The taste of all wild animals is almost inevitably tough and dry. Even if Bifang is brushed with fish oil, this is not a disadvantage in the wilderness. No matter how tough the meat is, it is still meat!
Especially for Bifang who had eaten fish for ten days in a row.
Delicious!
It's just that it easily gets stuck between teeth. Bifang doesn't know if there are any gold coupons for tooth correction in the system's store. If there are, he must exchange for one.
Human teeth will have some problems unless they have been professionally plastic surgery in a hospital. Many people don’t even know they have cavities.
Bifang has never been taken care of. Although her teeth are straight, she has two cavities. The teeth are not obvious and have no impact. She only feels obvious pain when she suddenly drinks cold water after drinking hot water. Apart from that, there are no other problems and she has never had any treatment.
"Pheasant meat has 2.5 times the protein of regular chicken and only one-fifth the fat of chicken. It sounds good, but in the wilderness, I would rather it be the other way around."
Bifang chewed up all the bones and meat, and continued to knead the pancake with rust. Muffled thunder sounded.
It is raining.
It was a light rain, drizzling.
The spectators heaved a sigh of relief when all the items that were being dried were moved inside the enclosure.
All the work came to a halt because of the rain, giving us some rare free time.
Bifang moved a stone and sat under the eaves. Water drops flowed down the green palm leaves and dripped at his feet, mixing with dust and rolling into beads. White smoke was emitting from the blast furnace not far away, and water vapor mixed with the white smoke floated into the gray sky.
Looking up at the sky, I was surrounded by tall trees and felt like a frog in a well.
The drone flew out from under the eaves, continued to rise, and landed above the trees. In an instant, the sky and the earth opened up, and all the troubles disappeared.
The sky was filled with mist, covering the endless green forest. Birds were flying swiftly in the rain, leaving a curtain of rain. A row of black ants lined up to crawl into a cave. Squirrels were curling up their soft tails and braving the heavy rain to deliver nuts to their warm tree holes. Big fish in the pit were floating up and bubbling.
The bubble burst, and a bird fell rapidly, landing on the wall, shaking off the rain.
Bifang was surprised by the unexpected guest and delighted by this moment of harmony.
On the slope behind the shelter, the water monitor looked up at the sky, not understanding what was so good about it, then looked down at the bird on the fence.
It's not common to see birds falling to the ground...
The water monitor licked the corner of its mouth, but looking at the figure at the door, it gave up the idea in its mind, turned around and went into the cave to hatch eggs, and swept the dust at the door with its huge tail.
After resting for a while, the bird jumped a few times and flew into the sky again.
Bifang watched it fly into the distance until it disappeared.
"Maybe it's in a hurry to go home, too. Like the water monitor, it has young birds waiting for it."
Bifang had a faint smile on his face.
Having a small hut in the rainforest that can shelter you from the wind and rain, and having enough food and clothing, this is probably the most basic happiness for human beings.
“Fly with all your might, so that when you are old and listening to the rain under the eaves, you will have those fleeting moments flowing through your mind, and you will not regret it.”
You have traveled all over the world. If you want to go to a place, even if you have no destination, you must believe that it will be beautiful there.
Taking out the stone slab, Bifang continued to make mud cakes.
On rainy days, enjoy the silky smoothness.
…
In the afternoon, more than twenty earth cakes of various sizes were placed on the ground, and nearly half of them had been used up by the iron bacteria. According to estimates, these twenty cakes were enough.
Coming to the blast furnace in the rain, Bifang did not add charcoal this time. He moved the stone slab away, and the flame inside was still dying, emitting billowing heat waves.
Holding the branch, he turned over the ashes. Among the five pottery pieces, one was completely shattered and turned into debris, and another had obvious cracks on the surface. Only three were intact.
"With a 60 percent yield rate, we're pretty lucky."
Bifang used two branches to pick up the pottery from the blast furnace. Rainwater fell on it and quickly evaporated, emitting white smoke. When one reached out to touch it, one could feel the high temperature.
Bifang immediately took the three pottery pots into the shelter to prevent them from being washed away by heavy rain and cracked by thermal expansion and contraction.
"Early bonfired pottery was mainly round-bottomed to avoid sharp corners that could easily break."
“The earliest purpose- built kilns were pit kilns or trench kilns, which meant digging a hole in the ground and filling it with fuel. The hole in the ground provided the best insulation, allowing for better control of the firing process.”
“In addition, the fish bone powder and stone powder I added also provide an open body texture, allowing water and other volatile components to easily leave the clay.”
"And the coarser particles limit the shrinkage of the pottery body as it cools, slowing down the entire process and reducing thermal stress and the potential for cracking."
"That's why I added extra substances. But even so, I originally estimated that only one or two might succeed, but I didn't expect there to be as many as three. It was quite unexpected."
Inside the house, the three pottery vessels were now neatly placed on the ground.
A drone flew nearby, capturing the entire scene in 360 degrees.
Although the appearance of the pottery jar has not changed, its luster is completely different from before it was put into the kiln. The surface is obviously smoother and has a faint oily sheen. It makes a crisp sound when knocked with a branch.
After cooling naturally, Bifang picked up a pottery jar, put his fingers into it and turned it around, but did not find any obvious cracks.
Pour water and let it stand, no signs of leakage.
A huge success!
Everyone was delighted.
Bifang lit a bonfire, cleaned the pottery jar, placed it in the flame, then cut the blanched pheasant into small pieces and put it in the jar.
After blanching, the blood foam inside the pheasant was further removed, which gave Bifang some confidence and he used all his skills to prepare this chicken soup.
These days, Bifang has collected a lot of good things nearby, even wild ginger!
Ginger, a magic weapon for removing fishy smell!
Place sliced galangal at the bottom, add chicken pieces, sprinkle with lemongrass, and finally cover with a lid. Stew a whole chicken in three pots at the same time.
"Pheasant meat is tough and tough, so we need to stew it for more than half an hour before adding other seasonings."
Bifang picked the newly found bamboo shoots and took out another strange plant, which was densely covered with small green particles.
This is……
[Fuck, Sichuan pepper?]
[Oh my god, there are peppercorns in the mountains? Am I seeing things?]
【Was this found in the wild?】
【Lao Fang found it when he was up there, why don’t I remember it? 】
[It is indeed from the mountains. Yesterday morning, Lao Fang went out for a walk and brought back a lot of strange things. This is not Sichuan pepper, but Litsea cubeba.]
"Yes, Litsea cubeba is also called mountain pepper, which is a mountain product and is usually only available in midsummer. But we were lucky enough to come across a premature one."
The fruit of Litsea cubeba is like smooth, round green peppercorns strung together on thin, thin stems, and the flavors are completely different: lemon, citronella, menthol...
Probably a mix of those smells.
