I Am the Crown Prince in France

Chapter 410: Sharp Weapon of Exit

Joseph frowned immediately. Although he didn't see clearly what happened just now, Alexandra was walking well and didn't turn towards the "extras". Why did she step on that person's foot?

It must be that the latter stretched out her foot herself.

He frowned and shook his head, ignoring the noble lady who was making trouble.

"Your Highness..."

Several noble ladies saw that the crown prince had no intention of condemning the little Russian girl, and they couldn't quarrel with a seven or eight-year-old child - it was probably asking for trouble if they really quarreled - they immediately stood up angrily, helped Triss walk out of the theater, and muttered quietly:

"It's impossible to perform on the same stage with such a rude woman!"

"Let's help Triss go back to the room to rest."

"I will tell everyone about her rude behavior..."

Alexandra looked at the few people who were about to leave, knowing that they wanted to isolate herself.

She blinked her eyes and chased after him:

"Dear ladies, are you angry because you wanted to attract the attention of His Royal Highness the Crown Prince but failed to do so?"

If an adult said this, it would sound weird, but when she said it as a child, it was innocent and sincere.

"You! You are talking nonsense!" An aristocratic lady immediately denied it excitedly.

"Oh? Then you don't want the Crown Prince to notice you?"

"No, no..." Several female nobles' faces turned purple and they turned around and fled the theater in a hurry.

Joseph, who was watching this scene, almost laughed out loud. He thought that this little girl was quite interesting. She was not willing to give in even when she was right. Are all Russian women so sharp?

Well, it seems to be true. When Elizabeth and Catherine were tsars, Russia was quite strong. On the contrary, when Peter III and Paul I were in power, Russia was in a mess.

Alexandra sighed when she saw the women leave, turned around and bowed to Joseph, apologetically saying:

"Your Highness, I'm sorry, I shouldn't have quarreled with them and prevented your rehearsal from continuing."

"It's not your fault." Joseph waved his hand, "You acted very well and were very brave. I'll find a way to find the missing actors."

In fact, he didn't have to do anything at all. There was a long line of people who wanted to perform on the same stage with the Crown Prince, and rehearsals started again half an hour later.

...

Northern suburbs of Paris.

Antoine Industrial Development Zone.

Yes, relying on the booming papermaking industry, Antoine's workshops and craftsmen are increasing. So Joseph simply designated this place as a new development zone.

In a factory covering more than 10,000 square meters to the southwest of Antoine, Lavoisier looked at the mechanical oven spewing white smoke in front of him, hugged his wife's shoulders standing beside him, and sighed sincerely:

"Dear, how did you make this thing in a month? You are really... the darling of the god of chemical experiments!"

Marianne smiled and said:

"In fact, I just made the specifications, asked someone to draw the drawings, and then handed it over to the ironworks in Saint-Etienne. They took more than 20 days to manufacture it, and a lot of time was spent on testing and transportation. Their equipment and management are much better than before."

"I originally thought that I had to wait for help to complete the work here." Lavoisier looked at his wife lovingly, "I didn't expect you to solve it all by yourself."

He said and looked at the huge equipment in the shed-rotating furnace, centrifuge, evaporating dish, reactor, and the most complicated gas scrubber.

These were basically built and tested by his wife. And before she married him, she didn't even know what chemistry was.

She is definitely a genius in the field of chemical experiments. Well, of course, it is also inseparable from his excellent teaching.

After Lavoisier obtained the Royal Alkali Method invented by His Royal Highness the Crown Prince, it took him less than a week to complete the laboratory preparation - as long as the principle is correct, it is not difficult with his experience.

The difficulty lies in how to mass produce.

In the chemical industry, once the amount of reactants increases, the preparation process will be completely different. For example, in a test tube, you only need to shake it to mix the reacting substances evenly, but when the amount becomes 1 ton, the mixing alone can drive people crazy.

How to make so many materials react fully, how to purify them, and how to preserve them are all big problems. As long as any link is not up to standard, mass production cannot be carried out.

This is especially true for alkali production. You know, according to the requirements of His Royal Highness the Crown Prince, 1.66 tons of soda is produced per day, so the mixed raw materials are several times this weight.

The core of this reaction is the recycling of ammonia, so there are extremely demanding requirements for the sealing of the equipment and the collection of gases.

Especially for the cleaning of ammonia. Ammonia is not only toxic, but also corrosive and flammable. It is very troublesome to clean up a large amount of it, which almost drove the Lavoisiers crazy.

In the end, His Royal Highness the Crown Prince proposed a general plan - Joseph only remembered that the gas scrubber was mentioned in the documentary, as well as the basic principle, but he didn't remember the specific details at all - and then Marianne worked day and night for three and a half months and actually designed this thing!

It can be said that as long as the confidentiality of the gas scrubber is done well, other soda preparation technical manuals will not be able to be copied even if they are given to other countries.

Lavoisier looked at the whole set of alkali-making equipment in front of him, and asked his wife, "Dear, how is the trial production going?"

"The raw material utilization rate is still a little low. His Royal Highness the Crown Prince said that it can reach about 70%, but I can only achieve 50%." Marianne said, showing excitement again, "But the trial production the day before yesterday took only 6 hours to produce 700 kilograms of soda. And the purity is very high."

Although Lavoisier had been mentally prepared, he was still secretly shocked when he heard this number-the current market price of soda is about 33 livres per 100 kilograms.

In other words, he made more than 230 livres by just starting the equipment casually the day before yesterday.

Moreover, soda has always been a priceless thing. It is easy for you to buy dozens of kilograms, but you have to wait a long time for more than 100 kilograms.

Before he could say anything, Marianne smiled and said, "Dear, we don't have to save soap anymore."

Among the raw materials for soap production, the most expensive are oils and soda ash. With the ability to mass-produce soda ash, France can even monopolize the soap industry around the world.

Although this thing is insignificant, if the global market is added up, it will exceed tens of millions of livres!

Lavoisier nodded vigorously: "And glass, paper, and dyes will become much cheaper in the future."

For France, this means that the costs of these industries will be greatly reduced, thus becoming a powerful export weapon.
