2Fe2O3+3C will generate 4Fe+3CO2 in a high temperature environment.

This equation is the key to making iron, and at the same time, the sulfur in the plant ash can accelerate the liquefaction of the metal and reduce the temperature required for ironmaking.

The high temperature and charcoal raise the temperature, and the plant ash lowers the required temperature, and the two sets of combination punches are played together to successfully refine qualified iron.

【what the **!】

[Why can't I understand at all?] 】

If the domestic audience can still understand, the foreign audience is already confused.

Why do you never seem to have heard of these things?

Did you really go to school?

[Why do I feel like I've never learned?] 】

[Education in China is terrifying! 】

[I remember we also taught, you didn't listen carefully in class......]

[I went to play basketball.] 】

[I might be in a relationship]

Mix all three kinds of ash together, add water to mix, and knead them flattened and rounded.

Making a piece of clay cake, Bi Fang said: "We are not doing experiments, there is no need to make the proportion so clear, as long as it is about one to one, three in one to make a piece." ”

[This is the DLC of the Earth OL, the Iron Age!] 】

[I'm so excited, there will be iron ingots soon, and soon there will be small iron swords]

[I bet five cents, after refining, there must be local tyrants who buy it at a high price! ] 】

The audience fantasizes that they are the lucky one, but when they think about it, they know that it is basically impossible.

Damn, they want it too!

[Lord Mu is gearing up, this discus, I want it! ] 】

[And Mr. Lin, who do you look down on, fight and fight]

[Mr. Lin doesn't seem to watch the live broadcast much, or Mr. Yao is a little more idle]

[I'll give 10 million! If Fang Shen agreed, then I didn't say it]

Rub it, roll it, and another black cylinder appears.

This was already the third piece, and Bi Fang put it aside to dry, and the time came to noon.

Today's weather is very hot and humid, Bi Fang wiped the sweat on 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 in direct sunlight, and Bi Fang removed the stone slab of the stove, placed it on the bridge, spread wood around it, lit a fire, poured in a large amount of black charcoal, and covered it.

[How long will this burn?]

[It should be soon, right?] 】

[No, I remember that the purple clay pot seems to be going to burn for a day? 】

Bi Fang estimated that it would take a long time, but it was definitely not as long as the purple clay pot.

The low-temperature pottery he made can be finished in about three to four hours, and it will definitely be good before dinner, and he can try the meat in the jar today.

"Now it seems that two cellars of charcoal are still a bit insufficient, and we will have to burn another cellar later."

Bi Fang looked up at the sky, the weather was too hot today, and the trees in the rainforest were tall and blocked the sky, so he couldn't judge the weather well.

"Looks like it's going to rain again?"

The drone's lens moved up, and everyone saw that the originally clear and cloudless sky had become gloomy again.

The audience is speechless, this rain is coming like this?

[Isn't it, it's raining again? 】

[Is there any mistake, it rained for five or six days on the eleventh? Raining half the time? 】

[Will it affect pottery making?] 】

Bi Fang nodded, but shook his head again, and said: "There will be a little impact, but the impact is not very big, after all, it is the rainy season, I took precautions against this situation when I built the blast furnace, and the construction of the entire shelter and blast furnace is on high ground." ”

The shelter has a wall, and although the bottom of the blast furnace is at the bottom, the overall terrain is high, and if the rain is not very heavy, the rain that falls on that square meter alone will not cause a great impact.

The clay pot was not prepared, and at noon Bifang still ate fish, vegetables, and two grilled chicken wings.

The taste of all wild animals is almost impossible to avoid firewood and dry, even if Bifang brushes fish oil, but for the wilderness, this is not a disadvantage at all, no matter how chai's meat, it is also meat!

Especially for Bi Fang, who has eaten fish for ten days in a row.

Fragrant!

It's easy to plug between the teeth, Bi Fang doesn't know if there is a gold coupon for orthodontics in the system's store, if there is, he must replace one

However, if it has not been professionally treated by the hospital, there are some problems with human teeth, and many people do not even know that they have worm teeth.

Bi Fang has never cared for it, although the teeth are straight, but two of them are insect teeth, which are not obvious, and there is no effect, that is, after a hot drink, there is a sudden cold drink, and there is obvious pain, and there is no other problem, so it has not been treated.

"Pheasant meat has 2.5 times the protein and one-fifth the fat content of regular chicken, which sounds good, but in the middle of the wilderness, I'd rather it be the other way around."

Bi Fang chewed all the bones and meat, and continued to knead the cake with the rusty soil, and the muffled thunder sounded.

It's raining in the sky.

It's a light rain, dripping.

The contents of the drying were moved into the inside of the wall, and the audience was relieved.

All the work was stopped because of a rain, and there was a rare free time.

Bi Fang moved a stone and sat under the eaves, water droplets flowed down the turquoise palm leaves, dripping at his feet, mixed with dust and rolling into beads, and the blast furnace not far away emitted white smoke, and the water vapor mixed with white smoke drifted into the gray sky.

Looking up at the sky, surrounded by tall trees, I looked like a frog at the bottom of a well.

The drone flew out from under the eaves, kept rising, and came to the trees, and in an instant, the world opened up, and all the depression disappeared.

The mist shrouded the green forest, birds flew in the rain and swept a curtain of rain, and the last row of black ants lined up into the burrow, and the squirrels rolled their big fluffy tails against the heavy rain to send nuts into their warm tree holes, and the big fish in the pit bubbled up.

The blisters burst, and a bird flew down and stopped on top of the wall, shaking off the rain.

Bi Fang was pleasantly surprised by this uninvited guest and delighted in this moment of harmony.

On the dirt slope behind the shelter, the water monitor lizard looked at the sky, not understanding what it was about, and looked down at the birds on the wall.

It's rare for a bird to land on the ground......

The water monitor lizard licked the corners of its mouth, but looking at the figure at the doorway, it finally gave up the idea in its mind, turned into the cave to hatch the eggs, and swept the dust from the doorway with its huge tail.

After resting for a while, the bird jumped a few times and flew into the sky again.

Bi Fang watched as it flew into the distance until it disappeared.

"Maybe it's in a hurry to go home, and like the water monitor lizard, there are young birds waiting for it."

Bi Fang had a shallow smile on the corner of his mouth.

There is a shelter in the rainforest, and there is plenty of food and clothing, which is probably the most basic happiness of human beings.

"Fly with all your might, so that when you are old and listen to the rain under the eaves, you will have those horse-like moments flowing through your mind, and you will not regret it."

You've traveled all over the world, and you're going to a place, even if you don't have a goal, but you have to believe that it's going to be beautiful.

Taking out the slate, Bi Fang continued to make mud cakes.

On rainy days, indulge in silky smoothness.

......

In the afternoon, more than 20 pieces of earth cakes of all sizes were placed on the ground, and nearly half of the iron bacteria were used, and according to estimates, these 20 pieces of bread were enough.

Braving the rain to come to the blast furnace, this time Bi Fang did not add charcoal, he removed the stone slab, and the flames inside would not be extinguished, braving the boiling heat.

Holding the branch and turning over the ashes, one of the five pottery pieces was completely shattered and turned into slag, and one had obvious cracks on the surface, leaving only three intact.

"Sixty percent of the finished product, we're lucky."

Bi Fang used two branches to clip out the pottery in the blast furnace, and the rain fell on it, quickly evaporating and emitting white smoke.

Sandwiched between three clay pots, Bi Fang immediately brought them into the shelter to prevent them from being washed by a large amount of rain and cracking under thermal expansion and cold contraction.

"Early bonfire-fired pottery was mainly round-bottomed to avoid sharp corners that could easily break down."

"The earliest kilns built for purpose were cave kilns or trench kilns, where a hole was dug in the ground and then filled with fuel, and the hole in the ground provided the best insulation for better control of the firing process."

"In addition, the fish bone meal and stone powder I added also provided an open texture of the billet so that the water and other volatile components could easily leave the clay."

"And the coarser particles limit the internal shrinkage of the pottery body when it cools, reducing the speed of the whole process and reducing the possibility of thermal stress and cracking."

"That's why I added extra substances, but even so, I originally estimated that there might only be one or two, but I didn't expect that there were as many as three, which is quite unexpected."

Inside the house, the three pottery vessels were now neatly placed on the ground.

The drone flies next to it, shooting at 360 degrees without dead ends.

Although the appearance of the clay pot has not changed, the luster is completely different from before entering the furnace, the surface is significantly smoother, with a faint oily shine, and the sound of tapping with a branch is also very crisp.

After natural cooling, Bi Fang picked up a clay pot, put his fingers in it and turned it around, and did not notice any obvious cracks.

Pour the water and let it stand, no signs of leakage.

Hit the jackpot!

The crowd rejoiced.

Bi Fang lights a bonfire, cleans the pot, places it in the flames, and then chops the blanched pheasant into small pieces and places it in it.

After blanching, the blood foam in the pheasant was further removed, which made Bi Fang regain some confidence and use all his strength to cook this chicken soup.

These days, Bi Fangruo has collected a lot of good things in the neighborhood, even wild ginger!

Ginger, go to the fishy artifact!

Slice the ginger at the bottom, put in the chicken pieces, sprinkle with lemongrass grass, and finally cover the lid, and simmer a whole chicken at the same time with the three spouts.

"The pheasant meat is also strong, we have to simmer for more than half an hour, and then put 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......

[, pepper? 】

[Wori, there are still peppercorns in the mountains? I'm not dazzled, am I? 】

[This was found in the wild?] 】

[Lao Fang found it when he was above, why didn't he remember? ] 】

[It is indeed in the mountains, yesterday morning, the old party went out for a walk, and brought back a lot of strange things, this is not pepper, it is wood ginger]

"Yes, wood ginger is also called mountain pepper, which belongs to mountain goods, and is generally only available in midsummer, but we were lucky enough to meet a premature baby."

The fruit of the wood ginger is like smooth and round green peppercorns strung together on the weak stalks, and the taste is completely different, lemon, lemongrass, menthol......

Presumably a mixture of these smells.

------Off topic------

Ants don't sleep, but they doze twice a day for eight minutes.
