I was watching short videos and was seen by ancient people

Chapter 252 Necessary skills for time travel - alkali production ()

"Beisu Qingfeng: If I were a senior in high school, I could tell you the truth clearly, but I have graduated from college for one year [see] [see]. 》

This……

People from all dynasties were shocked when they saw the comments on the sky screen.

This is what they so longed to have this time, but how come they would forget it after graduation in future generations?

This makes them feel incredible, and even feels that future generations have no respect for knowledge.

We must know that in their era, in order to learn knowledge, who did not go through a lot of hardships?

With the emergence of Tianmu, their lives gradually improved, and their children had an environment to learn.

But even so, their children cherish this hard-won learning opportunity.

Unlike the people of later generations on the sky screen, they will forget the knowledge they have learned.

They called their children and repeatedly told them to cherish this hard-won opportunity.

After all, they are living in an era where, if they are like the college students in the sky, they will never have the chance to learn.

Han Dynasty.

Kuang Heng looked at the comments on the marquee and felt that future generations simply did not appreciate the hard-won learning opportunities.

This also reminded him of his childhood, when he had to work during the day and had no time to study. He only had time to study at night.

But he didn't have the money to buy a lamp, so he had to cut a hole in his wall and borrow a neighbor's lamp to study.

However, what makes them most embarrassed is that sometimes there are no books to read. In order to get books, he works for others. He does not accept money from others, but agrees that he can borrow other people's books here.

This kind of learning opportunity, which is not easy to come by, will be remembered for his whole life, and it also allowed him to achieve his current achievements.

He also hopes that the people in the world are like him, and only in this way can he change his destiny.

At the same time, he hated future generations, but he didn't know how to cherish it when he had such a good learning opportunity.

Song.

Ouyang Xiu looked at the comments on the screen and sighed. He also felt that the people of future generations are really blessed in the midst of blessings.

I recall that in those days, he wrote on the sand in order to study and learn to read.

The later generations on the sky were extremely well-developed in materials and there was no shortage of pens, inks, paper and inkstones, but what was the use of such learning results?

This is just a waste of time and will be in vain in the end.

And what is the meaning of such a life? It is better to study hard and show your ambition.

"Freedom of the Wind: Potassium carbonate can also be filtered from plant ash dissolved into water, which can also be used in the early stages. 》

This……

People from various dynasties looked at the comments on the marquee, and he suddenly didn't know which one was correct.

Because the alkali produced by burning plant ashes and the alkali produced on the canopy have different effects.

But if it were different, that wouldn't be right, after all, they can both make soap.

People in various dynasties did not understand, and they did not know which one was correct.

They hope that Tianmu can give them answers, and also hope that they can get more knowledge from Tianmu to change their lives.

"The Sky of Love: I have learned how to make alkali and how to burn glass, so that I can make a fortune in ancient times. Now I am just short of succeeding in time travel!" 》

What is glass? Countless people from all dynasties became curious.

Some of them don't understand, what does this alkali production have to do with glass?

Are glass and soap the same? Can it also be made and sold for money?

If that is the case, they said that a video like this could be published on the awning, so that they can learn how to make glass and change their lives.

"Look at the Storm with Laughter: Three acids and two alkalis are the basis of industry. Our current life can be so materially rich because of the step-by-step efforts of our country's chemists. 》

This……

The emperors of various dynasties did not expect that the abundant supplies of later generations would rely on three acids and two alkali. Now that they have mastered one kind, they are also more curious about what the other two are?

If they master these things, will they be able to make their dynasty as materially rich as future generations?

They are eager to broadcast the technology of these three acids and two alkali on the sky screen as soon as possible, so that their people can become richer and their country more powerful.

"Southern Little Potatoes: Although the textbook talks about how to make alkali, and I know that alkali is the basis of chemistry, I just did a search and found out about the role of alkali.

The functions of bases include but are not limited to:

1. Neutralize the acid produced during dough fermentation to make pasta more delicious.

2. Neutralize organic acids or sulfides on dark green vegetables, remove pesticide pollution, and maintain the original color of vegetables.

3. Strong degreasing effect, can remove excess grease on dry food raw materials.

4. Release niacin that is not easily released in corn to prevent skin disease.

5. Industrially, soda ash is a very important chemical raw material, widely used in glass industry, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine and other fields.

6. Neutralize gastric acid and protect the stomach for patients with gastric ulcers and other gastric diseases. (Because alkali is highly destructive to some substances in plants, it cannot be abused)》

This……

People in various dynasties never expected that this alkali could have so many effects.

Originally, they thought that alkali could only make the steamed buns sweet and white, and it was an important raw material in making soap. However, they did not expect that they could be used in so many other ways.

After seeing this comment, merchants from countless tanneries in various dynasties bought some soda ash and started experimenting.

I found that it was just like what was said on the marquee, it could easily remove the oil from animal fur, making the items they made look better and softer.

They once again admired the superb technology of future generations, and at the same time they also hoped that they could learn more technologies in future generations and make their lives better.

Businessmen from other industries in various dynasties saw the comments on the marquee, and they also started experimenting according to their own industries.

They also found the use of alkali in metal smelting and textiles, but as for other industries, they have not yet found specific uses.

But they also secretly kept it in mind, hoping that they could find specific ways to use alkali in their industry in the future.

The imperial physicians from various imperial courts were extremely surprised when they saw that this alkali could actually cure diseases.

For them, this will be good medicine.

But they don't know how to use this "good medicine" and what the specific dosage should be.

They are doctors. If they let patients use it irresponsibly, it will only harm the patients. This is in conflict with their medical ethics.

In order to know the specific dosage, they could only verify it by themselves, and started experimenting little by little.

After their efforts, they finally experimented with a specific dose.

The imperial doctor who suffered from gastric ulcer even cured his own disease, which made them very excited.

They know how uncomfortable it is when suffering from gastric ulcer, and now that they have found a solution, how can they not be happy?

So they wrote a medical book detailing the main functions and dosage of alkali.

They hope that their verification results can be known to the world, so that more patients can slowly get better.

Doctors in various dynasties saw the use of the imperial physician's instructions. They were extremely surprised.

The medical skills they learned were all passed down from their ancestors, and there was no room for improvement in the future. How could they be taught by a prince now?
