Chengdefang.

Yang He was holding a piece of soap in his hand, marveling.

Zhao Xu was beside him, and Qu Sheng was introducing him to the entire production process of soap shop.

The Mining Search Department was established and officially launched the important task of mining search within Yanzhou.

Qu Sheng reported to him that the soap workshop was completed within two days.

There is no doubt that Yanzhou is currently developing steadily according to his plan.

"These pools are specially used to prepare caustic soda." Qu Sheng pointed to the twelve rectangular pools that lined up.

White calcium hydroxide precipitates in the pool.

Calcium hydroxide is slightly soluble in water, so most of it precipitates under the pond.

Above is a saturated calcium hydroxide solution.

At this moment, the craftsman was pouring out the clear solution in the pool and put it into the water tank.

Another craftsman poured soda ash into a water tank and stirred it.

There was a white film on the surface of other water tanks that had been left for a while.

The craftsman collects the film and sets it aside.

The rest is simple, just boiling meat oil and collecting the by-product glycerin.

"Qu Sheng, I did not misunderstand you. This soap shop is very good." Zhao Xu smiled with satisfaction.

Now the craftsmen of the soap shop are carrying out various processes in an orderly manner.

Batches of soap are produced.

"Thank you Your Highness to praise you." Qu Sheng said with excitement, "But for you, it is even more fascinating to be able to learn these skills that shock the world and the earth with Your Highness."

Yang He took the soap and looked at it for a long time, smelling it again and smelling it again.

At this time, I couldn't help asking: "Your Highness, what is this thing for?"

"It's used when bathing," Zhao Xu said, "In the future, you can add essence to it to add fragrance."

"Bath?" Yang He suddenly felt a little itchy, "Your Highness, let's go back and try it now."

After saying that, he saluted and slipped away with the soap.

Zhao Xu and Qu Sheng smiled and shook their heads.

"Your Highness, the matter of this soap shop has given the next inspiration that this caustic soda belongs to one of the three acids and two alkalis. Since caustic soda can be made now, why not just build a workshop and make all the three acids and two alkalis into the workshop production. After all, they are the basis of chemistry." Only two were left, Qu Sheng suddenly said.

During this task of independently building a soap shop, he experienced a kind of happiness.

That is the joy of turning things in the textbooks into reality.

Otherwise, no matter how much you learn, what's the use?

"Hahaha, you and I really want to go to the same place. I have said that this soap shop is just the beginning, and there are a lot of things you have to do next." Zhao Xu said with a smile.

The three acid and two bases are nitric acid, sulfuric acid, hydrochloric acid, caustic soda and soda ash.

In the history of chemistry, they are the earliest chemicals to appear.

Then, more chemicals are synthesized and evolved.

It can be said that in the chemical industry, they play an important role.

It is no less than the steam engine in physical principles and the artillery gun gun in military technology.

"It turns out that Your Highness has already been calculating." Qu Sheng chuckled softly.

Zhao Xu nodded. Another reason why he admired Qu Sheng was his neither humble nor arrogant attitude.

This is a person who does practical things, not a flatterer or a frivolous person.

In this way, he would be relieved to hand over the chemical industry in Yanzhou to him.

"You can choose students from the Science and Technology Academy to assist you. Next, you will build these three acid and two alkali projects." Zhao Xu patted his shoulder.

"Yes, Your Highness." Qu Sheng replied yes.

After patrolling the soap shop again, Qu Sheng returned to the Military Affairs Office, and Zhao Xu returned to the royal palace.

Next, the soap shop will be handed over to the business bank for management.

...

Yang Mansion.

When Yang Cheng returned home, he entered the bathroom.

Soon, he walked out of the bathroom with a comfortable face.

He looked at the pancreas in his hand and threw it on the ground, asking his servants to keep the soap well.

In Dasong, the thing that the rich people bathe is called Panzi.

This pancreatic seed is made of wood ash mixed with lard, and looks dark and dirty.

Now, he used soap, and he felt even more disliked when he looked at the pancreas.

"It's so magical. I've used it once, and I'll feel uncomfortable if I don't need it next time." Yang He sighed.

This soap washed away all the greasiness on the body.

He could imagine that he would not need this thing to take a shower, it would be like not washing.

In his opinion, as long as you use this thing, you will definitely be addicted.

Wear official robe.

He immediately went to the business bank. When this new business came out, as the head of the business bank, he naturally had to turn it into silver.

Even if His Highness King Yan doesn't say it, he will still move.

You can't ask the King of Yan to remind you of everything.

"Come here, summon the merchants in Yancheng and ask them to go to Shanshui Bath Hall to wait for the official, and they said that the official wanted to invite them to take a bath." Yang He said with his eyes turning around.

At the same time, he asked him to go to the soap shop to get a batch of soap and send it to Jinling, so that Dong An could do it in the same way and make the soap profitable as soon as possible.

He heard that Yanzhou was about to carry out large-scale infrastructure construction, and the money would be spent just like money.

As the head of the business, he naturally could not let Yanzhou lack money, otherwise he would be unqualified.

...

The palace.

When Zhao Xu came back, he also brought some soap back.

That day, he kept Feng'er and Luan'er in silence.

Now it's time to give them some experience.

"Soap? Can this wash away the greasy?" Feng'er asked holding the clean white soap.

Luan'er also looked curious.

Zhao Xu smiled wickedly when he heard this, "I want to know if it's not easy, so I will force you to take a shower with you."

"Your Highness..." Feng'er and Luan'er said in a sweet voice at the same time.

Zhao Xu laughed and pushed the two of them to the backyard.

Half an hour later, the three of them came out of the bathroom of the royal palace and were refreshing.

"In the hot summer, it's so comfortable to bathe this thing." Feng'er looked happy.

Luan'er said: "Your Highness, this thing is really not inferior to perfume."

"That's right, I'm going to add fragrance to it, so it will be fragrant after washing it." Zhao Xu said.

However, soap is just one of his purpose of establishing the soap shop.

Another important factor is that he also wants to get glycerol, a by-product in the soap manufacturing process.

At present, Yanzhou's firearms are facing a problem.

The quality of the gun barrel and barrel is comparable to that of the 19th century.

But you can only use the most primitive gunpowder, the black gunpowder.

This will undoubtedly limit the power of guns.

However, glycerin can be used to create a smokeless gunpowder with stronger kinetic energy than black gunpowder explosion.

However, in addition to glycerol, the production of this gunpowder also requires the cooperation of the three acid and two alkali chemical industry.

This is why Qu Sheng is given this task.

"Can you add flavor? Your Highness, this soap will definitely be very popular." Feng'er almost jumped up excitedly.

Seeing Zhao Xu's face showing contemplation, she didn't know that Zhao Xu was thinking about the problem of glycerin, but just thought that it was King Yan and thought about how to sell soap for a high price.

So he said, "Your Highness, the last time the Perfume Empress said it was very popular in the palace. Because the empresses in the palace liked it, it was soon passed to Jinling City. This time it might as well send some to the palace, which can also show your highness's filial piety."

Zhao Xu came to his senses when he heard this, and nodded, "Well, it makes sense, just do it."
