Chapter 16 Making caustic soda,
This is crude distillation. After the first distillation is completed, the oil and water will be separated, and then it will be distilled two or three times to obtain high-purity flower oil.
At dusk, I saw a lot of gold and silver waving to him.
Xu Miaojin thought, "You want to make spices?"
Spices are indeed expensive.
Especially tribute spices are far more expensive than those circulated in the private market, but spices are generally powder or granular, so there is no liquid form.
Smile at dusk, "Shower Gel."
Xu Miaojin looked question marks and pouted and dissatisfied with the dusk's deception, "You said you were going to do Chanel before."
Dusk laughed dryly, "I said it casually."
Xu Miaojin "..."
After all, he was a yellow girl. I was embarrassed to stay here for too long and said softly, "I came here today to tell you two things. One thing is that Zhu Di ascended the throne and planned the year name Yongle. The second thing, Zhu Di ordered that Fang Xiaoru be executed at Jubao Gate and the ten clans will be executed."
It's confirmed.
Dusk did not make up random things. He was really a time traveler who could predict some things in the future.
The dusk is dark.
I felt a little guilty when I failed to save this scholar.
He stood up, bent down to the direction of the treasure gate in his heart, and sighed softly, "Mr. Xiangcheng, go."
Fang Xiaoru, whose courtesy name was Xizhi, and whose name was Xigu, and whose pseudonym was Xunzhi, once named his study school by "Xunzhi". Because his hometown was originally from Kuchengli, he was called "Mr. Qiancheng"; because when he was a professor in Hanzhong Prefecture, King Xian of Shu named his study place "Zhengxue", also known as "Mr. Zhengxue".
He died on July 25, 1402 at the age of forty-five.
Posthumously named Wen Zheng.
The only great scholar in history who was killed by ten clans.
Wu Yubi whispered, "Brother Sunset, the direction is wrong, there, and it has not been executed yet."
The dusk is extremely awkward.
Xu Miaojin said again, "I already know the conversation between you and Zhu Di in Jinshen Hall that day. Although you didn't save Fang Xiaoru, you also tried it. It's just that the world is like this. You and I can't resist the imperial power. Don't blame yourself. You have saved Huang Guan, the three-yuan genius, and you are worthy of this scholar in the world."
Xu Huizu is in trouble now.
It does not mean that Xu Miaojin is in a miserable state. With Empress Xu supporting him, the Xu family is still a royal relative after all. There are many old friends in Jianwen in the palace, so Xu Miaojin can still know a little about the palace.
"I'm leaving."
Xu Miaojin took Xu Yin away.
He sat down again at dusk, and found out from the corner of his eyes that Wu Yubi was in a bad mood, and sighed inwardly.
I'm afraid this is one of the reasons why Wu Yubi is unwilling to enter the officialdom.
Not forced.
Wu and Bi continued to grow wildly. If he forced himself to make up for his simple thoughts about his career and really participated in the imperial examination and became an official in the future, then at most, there would be one more Qing minister in the Ming Dynasty.
But there will be one great scholar of Neo-Confucianism and educator.
Times of Day.
At dusk, I finally got the purified lotus oil, and the porcelain bottle as big as a teacup was almost half filled.
It's enough for the time being.
In the evening, Wu Pu returned and pulled the dusk into the study, saying sadly and shockedly, "You really got it right. General Fang Xiaoru was executed by Jubaomen and killed ten clans. Friends and disciples are the ten clans."
It was sad because of Fang Xiaoru's death.
The shock is because dusk can really predict the future.
Dusk nodded, "Uncle Wu believes that I am a time traveler now?"
Wu Pu restrained his desolate thoughts and said in confusion, "What is the time traveler?"
Xun smiled, "Time traveler, it's very simple. It's actually a profession, similar to a fortune teller, but the fortune teller is stronger because he is the chosen son of God, so he can truly predict the future, and the fortune teller can only speculate."
These words were also fooling Zhu Di.
But I didn’t dare to say that the son of God was chosen at that time. Otherwise, when Zhu Di heard this, I would be the emperor. You said that you are the son of God, and you want to rebel too?
Drag out...
Then I probably can't get out of the Forbidden City.
Wu Pu suddenly realized, "Is it comparable to "Tuibei Tu"?"
Dusk thought for a while, "I am more accurate than "Tuibei Tu" in these hundreds of years, but six or seven hundred years later, "Tuibei Tu" is more accurate than me."
Hundreds of years?!
Wu Pu was stunned on the spot.
After a long time, after reacting, my eyes became much hotter when I looked at dusk, and I was as respectful as a god.
Dusk felt very uncomfortable and smiled and said, "Uncle Wu doesn't need to do this. I'm in your house now. Just treat me as your nephew. If you don't dislike me, we will be a family in the future."
Wu Pu smiled.
I read that right, dusk is indeed maturity and stability different from his age.
Good.
After confirming the ability of the time traveler in the evening, Wu Pu no longer cared about the troubles at home these days at dusk. It was still the same rule at night, so they randomly checked the knowledge of the two.
Wu and Bi passed the test successfully.
At dusk, there were some words in "Thousand Character Text" that could not be recognized.
Wu Pu was not in a hurry either.
Just learn this speed again at dusk, only about one or two months, and you can probably read the Four Books and Five Classics.
Continue to start a business at dusk.
Lotus oil has been distilled yesterday, and caustic soda is going to be made today.
Caustic soda is sodium hydroxide.
The alum used in fried dough sticks is also called alkali, but it contains impurities such as aluminum, so it is still necessary to chemically react lime and shell powder. Yingtianfu is not near the sea and cannot find shells, so it can be bought, but unfortunately there is no money.
I came back to try the clam shell picked up at dusk.
If the clam shell is not good, sodium hydroxide can also be extracted from the wood ash.
Put the clam shell into stone pounding and crush it into powder. Stone pounding is the original tool for mashing peanuts, sesame and other crops to make rice cakes, similar to the grinders in later generations.
This is a physical job.
Wu Pu's family did not have stone pounds, so he went to Hu Guang's house next door to borrow it.
After working hard all morning, I got a few kilograms of clam shell powder, I returned home and found a large washbasin, mixed the ripe lime and clam shell powder evenly, and added water to stir continuously.
It's still a physical job.
The calcium hydroxide in ripe lime must be fully reacted with sodium carbonate in muss shell powder to obtain calcium carbonate precipitation and sodium hydroxide solution, and be careful.
Sodium hydroxide solution is alkaline and can easily burn the skin.
It was done without any danger.
Put the sodium hydroxide solution into a temporary stove, heat and distillate to remove excess water powder, and obtain sodium hydroxide precipitate, which is also a serious hot alkali.
It's just that because it contains a small amount of impurities, it fails to show colorless crystals, and some white opaque crystals.
There should be impurities such as potassium.
At dusk, I went to the kitchen to get salt, made saturated brine, and rinsed the sodium hydroxide repeatedly.
After that, I finally got pure caustic soda.
The principle is also simple, because the sodium ions in saturated salt water are saturated, and all sodium hydroxide will not dissolve, while other impurities will dissolve into it.
Wine, lard, caustic soda, lotus oil.
All have been made.
Chapter completed!
