2fe2o3+3c will generate 4fe+3co2 in a high temperature environment.
This equation is the key to Bifang's iron-making. At the same time, the sulfur in plant ash can accelerate the liquefaction of metal and reduce the temperature required for iron-making.
High temperature and charcoal increase the temperature, and plant ash lowers the required temperature. Only when the two sets of combined fists are punched together can qualified iron be successfully refined.
【what the **!】
[Why can’t I understand it at all?]
If the domestic audience can still understand it, the foreign audience is already confused.
Why do you seem to have never heard of these things?
Did you really go to school?
【Why do I feel like I’ve never learned anything?】
【Chinese education is too scary!】
[I remember we also taught it, but you didn’t listen carefully in class...]
【Went to play basketball.】
【Maybe I'm in love】
Mix all the three types of ash together, add water to the mixture, and flatten it into a round shape.
After making a piece of earth cake, Bi Fang said: "We are not doing an experiment, there is no need to make the proportions so clear, as long as it is roughly one to one, three in one will be made into one piece."
[This is the DLC of Earth OL, the Iron Age!]
[I’m so excited, there will be iron ingots soon, and there will be a small iron sword soon]
[I bet 50 cents that after refining it, some rich man will definitely buy it at a high price!]
The audience all imagines that they are the lucky one, but after thinking about it, they know that it is basically impossible.
Damn it, they want it so much!
[Prince Mu is gearing up, I want this discus!]
[And Mr. Lin, who do you look down on? Let’s start a fight]
[Mr. Lin doesn’t seem to watch live broadcasts very much, but Mr. Yao is more leisurely]
[I will pay 10 million! If Fang Shen agrees, then pretend I didn’t say anything]
After rubbing and rolling, another black cylinder appeared.
This was already the third piece. Bi Fang put it aside to dry, and the time came to noon.
The weather today was very hot and humid. Bi Fang 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 pot on the ground was all dry under direct sunlight. Bi Fang removed the stove stone slab, placed it on the stove bridge, spread wood around it, lit a fire, poured in a large amount of black charcoal, and closed the lid.
[How long will this take to burn?]
【Should it be soon?】
[No, I remember that the purple clay pot seems to have to be boiled for a day? 】
Bi Fang estimated it and felt that it would take a longer time, but it would definitely not take as long as a purple clay teapot.
What he makes is low-temperature pottery, and it can be fired in about three to four hours. It will definitely be ready before dinner, and I can try the pot meat today.
"Now it seems that two cellars of charcoal are not enough. We will have to burn another cellar later."
Bi Fang looked up at the sky. Today's weather was too hot. The tall trees in the rain forest blocked the sky, making it difficult to judge the weather well.
"It seems like it's going to rain again?"
The drone lens moved up, and everyone saw that the originally cloudless sky had become gloomy again.
The audience was speechless. Is this rain going to come just like this?
【No, it’s raining again?】
[Is there any mistake? It rained five or six days out of the eleventh day? It rained half of the time?]
【Will it affect pottery making?】
Bi Fang nodded, but then shook his head and said: "There will be a little impact, but not a big impact. 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 top of the terrain.
Somewhere high."
The shelter has walls, and although the bottom of the blast furnace is underneath, the overall terrain is high. If the rain is not heavy, the impact of just one square meter of rain will not be great.
The clay pot was not prepared yet, so Bifang still had fish, vegetables, and two grilled chicken wings for lunch.
The taste of all wild animals is almost unavoidable. Even if Bifang uses fish oil, this is not a shortcoming at all in the wilderness. No matter how dry the meat is, it is still meat!
Especially for Bi Fang who had eaten fish for ten days in a row.
Fragrant!
It's easy to get stuck between teeth. Bi Fang doesn't know if there are gold coupons for orthodontics in the system's stores. If there are, he must get one.
As long as it has not been professionally treated by a hospital, human teeth will have some problems, and many people do not even know they have cavities.
Bi Fang has never taken care of him. Although his teeth are straight, two of them are cavities, which are not obvious and have no impact. It is only after a hot drink and a sudden cold drink that he feels obvious pain. Other than that, there are no other problems, so he has been there.
No processing.
"The protein of pheasant meat is 2.5 times that of ordinary chicken, and the fat content is only one-fifth that of chicken. It sounds good, but in the wilderness, I would rather it be the other way around."
Bi Fang chewed up all the bones and meat, and continued kneading the cake with the rust, and a muffled thunder sounded.
It's raining.
It's light rain, pattering.
All the things that were being displayed were moved inside the wall, and the audience breathed a sigh of relief.
All the work stopped because of the rain, and I had rare free time.
Bi Fang moved a stone and sat under the eaves. The water droplets flowed down the green palm leaves and fell on his feet, mixing with the dust and rolling into beads. The blast furnace not far away was emitting white smoke, and the water vapor mixed with the white smoke.
Smoke drifted high into the gray sky.
Looking up at the sky, surrounded by tall trees, I felt like a frog at the bottom of a well.
The drone flew out from under the eaves, continued to rise, and reached the trees. In an instant, the world opened up, and all the worries disappeared.
The water mist in the sky shrouded the green forest that stretched for thousands of miles. Birds flew rapidly in the rain, leaving a curtain of rain. The last row of black ants lined up to get into the cave. The squirrel rolled up its big fluffy tail and carried the nuts to the heavy rain.
He entered his own warm tree hole, and the big fish in the earth pit floated up and bubbled.
The blisters burst, and a bird quickly fell down and landed on the wall, shaking off the rainwater all over its body.
Bi Fang was surprised by this uninvited guest and was delighted by this moment of harmonious coexistence.
On the slope behind the shelter, the water monitor lizard looked at the sky, wondering what was so interesting about it, and then looked down at the birds on the wall.
There are not many birds that fall on the ground...
The water monitor licked the corner of its mouth, but looking at the figure at the door, it finally gave up the idea in its mind, turned around and went into the cave to hatch its eggs, its huge tail sweeping the dust at the door.
After resting for a while, the bird jumped a few times and flew into the sky again.
Bi Fang watched it fly into the distance until it disappeared.
"Perhaps it is also eager to go home. Like the water monitor, there are also baby birds waiting for it."
There was a slight smile on Bi Fang's lips.
There is a sheltered hut in the rainforest, with plenty of food and clothing. This is probably the most basic happiness for human beings.
"Fly with all your strength, so that when you are old and listen to the rain under the eaves, you will have those fleeting moments passing through your mind. You will not regret it."
You have traveled all over the world, and you want to go to a place. Even if you have no goal, you have to believe that it will be beautiful there.
Taking out the slate, Bi Fang continued making mud cakes.
On rainy days, enjoy silky smoothness.
...
In the afternoon, more than 20 earthen cakes of various sizes were placed on the ground. The iron bacteria used nearly half of them. According to estimates, these 20 cakes were enough.
Went to the blast furnace in the rain. This time Bi Fang stopped adding charcoal. He removed the stone slab, but the flame inside was still burning, and there was a billowing heat wave.
He held the branch and turned over the ashes. Among the five pottery vessels, one was completely shattered and turned into slag, and another had obvious cracks on the surface, leaving only three intact ones.
"With a yield of 60%, we are very lucky."
Bi Fang used two branches to pinch the pottery out of the blast furnace. When the rain fell on it, it quickly evaporated and white smoke appeared. If you reach out and touch it, you can still feel the high temperature inside.
Holding the three pottery pots, Bi Fang immediately brought them into the shelter to prevent them from being washed away by heavy rain and breaking due to thermal expansion and contraction.
“Early campfire-fired pottery was mainly round-bottomed to avoid sharp corners that would easily cause breakage.”
“The earliest purpose-built kilns were cave kilns or trench kilns, which meant digging a hole in the ground and spreading fuel over it. The hole in the ground provided the best thermal insulation layer, allowing for a better firing process.
control."
"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."
"Moreover, coarser particles will limit the internal shrinkage of the pottery body when it cools, slowing down the entire process and reducing the possibility of thermal stress and cracking."
"This is the reason why I added additional substances, but even so, I originally expected that only one or two would be successful, but I didn't expect that there would be as many as three, which is quite unexpected."
Inside the house, three pottery vessels were now neatly placed on the ground.
The drone flew next to it, taking 360-degree shots without blind spots.
Although the appearance of the clay pot has not changed, the luster is completely different from before it was put into the furnace. The surface is obviously smoother, with a faint oily sheen, and the sound is very crisp when tapped with a tree branch.
After cooling naturally, Bi Fang picked up a clay pot, put his fingers in and turned it around, but did not notice any obvious cracks.
Pour the water and let it sit. There will be no signs of leakage.
A big success!
Everyone was delighted.
Bi Fang lit a bonfire, cleaned the clay pot, placed it in the flames, then chopped the blanched pheasant into small pieces and put it in it.
After blanching, the blood foam in the pheasant was further removed, which allowed Bi Fang to regain some confidence and use all his strength to prepare the chicken soup.
These days, Bi Fangke has collected a lot of good things nearby, even wild mountain ginger!
Ginger, the magic weapon to remove fishy smell!
Put sliced mountain ginger on the bottom, add chicken pieces, sprinkle with lemongrass, finally cover the lid, and stew a whole chicken at the same time with three spouts.
"The pheasant meat is very chewy. We need to stew it for more than half an hour before adding other ingredients."
Bi Fang picked up the newly found bamboo shoots and took out another strange plant, which was densely packed with small green particles.
This is......
【Holy shit, Sichuan peppercorns?】
[Wori, are there still peppers in the mountains? Am I not dazzled? 】
【Is this found in the wild?】
[Lao Fang found it when he was on the top, why don’t I remember it? 】
[It is indeed from the mountains. Yesterday morning, Lao Fang went out for a walk and brought back many strange things. These are not Sichuan peppercorns, but wood ginger seeds]
"Yes, quince is also called mountain pepper. It is a mountain product and is only available in mid-summer. But we were lucky and encountered a premature plant."
The fruit of Mujiangzi is like smooth and round green peppercorns connected in series on thin thin stems, and the taste is completely different, lemon, lemongrass, menthol...
Probably a mix of these smells.
