In the evening, my father came back, and he was still carrying the alkali stone, miscanthus salt, lime and other things that Zhang Chao had bought for him.
Entering the door, Dad couldn't help but be surprised when he saw the broken cave that had changed greatly.
The dilapidated cave was replaced with a new stove, and Zhang Chao also took his Zhang family class to pour out the old cave inside and out.
A few simple beds, tables, and cabinets were scrubbed and rearranged, and the room was re-filled with loess and tamped.
Even the walls and roof of the cave have been cleaned, the cobwebs and soot have been swept away, the old windows Keshan have also been repaired, and new reed curtains have been replaced.
Walked around the courtyard of Daddy's house a few times, smiling with satisfaction.
"You put the kang up."
Zhang Chao smiled and talked about these things that happened today, and my father heard that Zhang Chao accepted Keshan Ke Wu as an apprentice, and also set up a Zhang family class, ready to specialize in pankang and stove transformation technology in the future, but also nodded in praise.
"Brother Muramasa is a shrewd person and a person who talks about rules, and he is also for your good."
"This kang stove is really easy to use," the old man turned around the new kang stove a few times, and finally asked with some anxiety.
The cowhide has been blown out, and Zhangjiaban has set it up, if it is found to be useless in the end, it will be embarrassing.
"You'll find out in three days."
The kang can't sleep right away, and the stove still has to be dry.
Therefore, this meal in the evening is the filial piety of Zhang Chao's two apprentices.
Now Zhang Chao's family is no longer a family of two, the two soldiers sent by the military government, and the two Bai Zhi and Zhiyi sent by the county, these four people are now in the Zhang family, so they eat and live in the Zhang family.
Ke Shan and Ke Wu knew that their father's family couldn't get together today, so they each sent the steamed cakes.
The steamed cakes sent by the two families are actually yellow steamed buns, made of millet flour after grinding, and red date paste is also placed in it for filling.
The amount is quite sufficient, but Zhang Chao still feels very sour when he eats it. barely ate two, and Zhang Chao had no appetite.
While the sky was still a little bright, Zhang Chao took alkali stone, miscanthus salt, and lime to refine alkali.
The chemical name of miscanthus nitrate is sodium sulfate decahydrate, alkali stone is also trona sodium bicarbonate hydrate, and lime is mainly calcium oxide.
Miscanthus nitrate can be used to make soda ash and sulfuric acid, and soda stone can also be used to make soda ash.
It is very convenient to use these things to refine alkali in later generations, there are many methods, and it is also efficient and high-energy.
But in Datang, there are many materials that are not available, so it will be more troublesome.
However, Zhang Chao does not need a large amount, and he does not have such high requirements for purity, so he can still get the desired alkali if it is more complicated.
The two government soldiers and the two juniors in the village saw Zhang Chao holding a lot of medicinal herbs in the courtyard, and began to set up a clay pot to make a fire.
Dad came over to take a few looks, and felt that Zhang Chao seemed to be burning Dan with a Taoist.
After asking a few questions, Zhang Chao said that it was not alchemy, but just a medicine, which was used to make pasta seasoning, and the pasta would not be sour after use, but it could be fluffy and delicious.
He was a little incredulous, but he just shook his head and stepped aside.
He has already gone to the county today to hire a feng shui master, and he will come to see feng shui tomorrow.
After looking at Feng Shui, he has to officially prepare to start building a cave, there will be many things to build a cave, and he has a lot to think about.
No one bothered, so Zhang Chao started his experiment seriously.
This is an experiment that consists of multiple chemical reactions, and finally refines what you need.
Soda stone, that is, the trona block in the saltwater lake, is sold in pharmacies.
It seems that all kinds of chemicals are either used in medicine or alchemy, so it is difficult to buy them elsewhere, but doctors and alchemists will definitely have all kinds of chemical materials in their hands.
In the Ming Dynasty, the divine doctor Li Shizhen's herbal medicine had alkali stone written in the wood, and in the Ming Dynasty, there were already smart people who found that alkali can be obtained by refining alkali stone, which is used for laundry and pasta, and makes a lot of money.
However, at present, there are only two functions of alkali stone, one is that it is used as medicinal materials in some prescriptions, and the other is that it is used by Taoist priests for alchemy.
Trona is the most convenient way to process caustic soda, first make the alkali stone into lye, then add a certain amount of lime, and finally after multiple processes, it finally becomes caustic soda.
However, what Zhang Chao needs is edible soda for pasta, not this highly corrosive caustic soda.
But Zhang Chao still refined and synthesized a small part of caustic soda first, just because caustic soda is the best synthetic, and caustic soda is still very effective, such as soap and paper, but this kind of thing is needed.
Zhang Chao carefully checked the caustic soda he made, the quality is not so good, and the purity is not high, but it is definitely caustic soda.
But now Zhang Chao is not in a hurry to make soap, the successful refining of caustic soda just now let him know that the little chemical knowledge he remembers in his head is still useful.
The successful refining of caustic soda shows that the method of making soda ash and baking soda and even the method of making sulfuric acid is feasible.
It's just a little more complicated.
Zhang Chao's enthusiasm for fighting was high, and then he was in full swing into refining.
While thinking about building a house, Dad glanced into the courtyard from time to time.

Seeing Zhang Chao tossing there without distraction, he could only smile bitterly.
After tossing for a long time, after several failures close to success, Zhang Chao finally refined soda ash and sulfuric acid.
In the end, the iron was struck while it was hot, and baking soda was processed from soda ash.
Soda ash is also known as sodium carbonate, while baking soda is sodium bicarbonate.
Soda ash, like caustic soda, is not directly edible, but after being processed into baking soda, it can be used as a food additive.
With soda ash, it is very simple to make baking soda, and you can get it by directly passing carbon dioxide into the soda ash solution.
"San Lang, it's not early, don't mess around."
Daddy couldn't help but come over and shout.
"Get it right, Daddy."
Zhang Chao said to his father with a smile, in front of him, there were already several finished products of his in several pottery bowls, caustic soda, soda ash, baking soda, and sulfuric acid.
There were not many of them, but at least they worked.
Dad looked at the bowls in front of Zhang Chao, there were powders and liquids in them, and he could smell the pungent smell from afar.
"And that's it" "Well, it's done."
"This thing can be used to make noodles, why do I smell pungent?"
"Of the four, only this flour alkali is used to make dough, and the rest are not."
Zhang Chao pointed out the baking soda to his father, and for convenience, he directly called the baking soda a face alkali.
Seeing that his father was still suspicious, Zhang Chao planned to speak with facts.
"Daddy, I'll use this to make some steamed cakes now, and you'll know if it's useful when you see it."
Zhang Chao planned to make the yellow steamed buns he had eaten tonight, he ate less just now, so there were a few left in the basket, and then they would compare them and make a judgment.
"Bring the millet noodles."
Daddy brought the ground millet noodles, which are also called yellow rice or millet rice, which are larger than corn.
"Daddy, bring some more rhubarb rice noodles."
There are also glutinous and japonica noodles, one soft and one hard.
Everyone is accustomed to calling the hard one millet rice, which is not sticky and suitable for steaming cakes.
The soft one is used to be called rhubarb rice, and this one is suitable for pastries.
Zhang Chao wants to make yellow steamed buns, and he doesn't plan to use all millet noodles like the villagers in Zhangjiagou.
Instead, it uses a mixture of millet noodles and seven combinations, and then three combinations of rhubarb rice noodles.
Mix the flour together with seven to three, add water and mix well.
After making good noodles, Zhang Chao put him in a large bowl and took a damp cloth to cover it.
"Wait for him to send an hour's face."
Making pasta and other fermented dishes is a helpless thing, and there is no hurry.
Zhang Chao and his father sat in the house and lit a fire, and several people chatted together on the fire.
It's still about building a new cave, which cellar makers to invite, which villagers to invite to help, what materials to buy, and vegetables to buy, and so on.
Before you know it, an hour has passed.
At this time, it was also completely dark, and the village began to fall silent, and most of the villagers rested at sunset.
At night, I am reluctant to light the lamp and spend oil, either I have to burn a fire to roast, or I have to go to bed early.
Dad lit the oil lamp, and the soybean oil used for the oil lamp was not cheap, although it was used for lighting.
In the peaceful years, you have to pay a pound of 100 yuan, and now the grain is expensive, and this soybean oil is also expensive, a pound is worth hundreds of yuan, and you need at least one or two oils for a night, and it costs dozens of yuan.
The dough has already been fermented, and now it is time to put in the yeast for a second fermentation.
Zhang Chao mixed the old dough yeast with the noodles that had been sent evenly.
It's a pity that there is no sugar.
At this time, sucrose was only refined by Indians, and it was still extremely expensive and scarce.
The people of the Tang Dynasty want to eat sweet, and most of them can only eat honey.
Either you eat maltose, and Datang's maltose even has a special name, called Ao.
And Datang's desserts, that is, the drinks that add gluttony, are sweet and sweet, which comes from this.

There is neither honey nor maltose at my father's house, let alone sugar, so Zhang Chao has to do it.
After putting in the old flour yeast, Zhang Chao added a little bit of flour alkali, which is also the biggest difference between his yellow steamed bun and Datang steamed cake.
After adding warm water and mixing the dough into a moderate firmness, Zhang Chao put the dough into a large bowl and covered it again.
This time, it had to ferment for four hours.
"Okay, when it dawns tomorrow, the noodles will be ready."
"That's good," Daddy, they were all surprised, and there was no difference between ordinary steamed cakes.
"There are red beans and red dates at home, no, if there is, I will make some red bean paste cake filling and put it in the steamed cake tomorrow."
Ke Xiaoba hurriedly said, "My family has it, my family has it, I'll go and get it." ” Before Zhang Chao could reply, he had already run out.
After a while, Ke Xiaoba had already run back, and sure enough, he took red beans and red dates.
Zhang Chao washed and steamed the red beans and red dates and then made them into red bean paste, and everyone was still looking at him.
"Now everyone goes to sleep, tomorrow morning when the noodles are ready, we will make steamed cakes with red bean and date filling."
After a simple wash, Zhang Chao went to sleep.
Before dawn, Zhang Chao was woken up.
When I opened my eyes, I saw that my father and the other four were all dressed and standing beside his bed.
"San Lang, your face is fine."
Zhang Chao looked at their red-eyed appearances, and estimated that they didn't sleep well last night. t1706231537:
