I Am the Crown Prince in France

Chapter 372 New Artifact

Joseph had no idea that Queen Marie had arranged a new "marriage" for him, and it was a very cute little girl.

At the dinner, he was still cautiously preparing to continue to deal with his mother's urging to get married, but the queen just gave him a look of "I understand" from time to time, and did not mention it again, but talked about some Russian customs.

At the subsequent dance, Joseph became the focus of all the nobles.

A prince who was less than 16 years old led his troops to defeat the Prussian and Hanoverian armies on the battlefield, which made the nobles constantly compare him with the Sun King Louis XIV.

Some people even said that "His Royal Highness the Crown Prince will definitely surpass the Sun King."

When Louis XVI said that he wanted to build a statue for the crown prince, some ministers did not agree, after all, the king himself did not have a formal statue in public.

After the news that the Guards Corps defeated Charles II was sent back to Paris, no one raised any objections. Artists from all walks of life gathered at the Palace of Versailles upon hearing the news, vying to sculpt the statue of the crown prince.

The ball started with the passionate music "Triumph", and all the way was about war and victory. The nobles also changed their usual gentle style and danced in a military style.

When the ball was halfway through, a famous poet came to the center of the Hall of Mirrors and recited a hymn to Joseph loudly, which directly pushed the atmosphere to a climax.

Joseph looked at the nobles who were extremely excited at the ball and praised him generously, and couldn't help but sigh in his heart: Sure enough, victory in foreign wars is the best stimulant for a country. The dissatisfaction and opposition caused by the abolition of noble privileges have now basically subsided. At least on the surface, the nobles have become extremely supportive of the royal family. I hope this can reduce the resistance to the land redemption policy on the noble side.

The ball lasted until late at night, and Joseph was able to return to the palace. Various social activities made him feel more tired than fighting three days on the front line.

The next morning.

Joseph had a simple breakfast and dragged his tired body to the Royal Armoury next to the plane tree forest on the southeast side of the Palace of Versailles.

The British Foreign Secretary would not arrive in Paris for about a week. He had to take advantage of this gap to hurry up and make the bulletproof inserts that he had been planning for a long time.

As soon as he walked out of the palace gate, Joseph saw that the spacious corridor was full of noble ladies dressed up in fancy clothes. In an instant, all kinds of bold, graceful, and resentful seductive eyes came from all directions, making his scalp numb.

Eman leaned close to his ear and whispered: "Your Highness, most of them have been waiting here at three or four in the morning. Some even didn't leave after the ball ended..."

Perna, who had just finished a routine examination for Joseph, followed him out. The eyes of the ladies around her suddenly became cold and murderous, which frightened her so much that she lowered her head and fled back to the imperial doctor's office on the second floor.

Joseph ignored the beautiful scenery along the way and walked quickly to the outside of the Palace of Versailles.

When he arrived at the square, he touched his chin with stubble and gritted his teeth in his heart: Let you jump! When my puberty is over, I will definitely pick a few to "slaughter"!

Martinel, the head of the Royal Ordnance Factory, obviously expected that His Royal Highness the Crown Prince would come, and he waited at the door with a group of managers early in the morning.

Joseph nodded to the bowing group, and then went straight to the point: "Mr. Martinel, are all the things I asked you to prepare ready?"

The latter hurriedly pointed to a shed on the west side: "Yes, Your Highness, everything is ready, just put it there."

When Joseph was in the Southern Netherlands, he wrote a letter to list the materials needed to make bulletproof inserts, attached simple process requirements, and sent it to the Royal Ordnance Factory.

After entering the shed, Martinier had boxes of iron sheets, porcelain sheets, silk and other things placed in front of the crown prince, and asked for credit: "Your Highness, look, I asked the craftsmen to make iron sheets of different hardness and thickness for you to choose. The porcelain sheets were customized from the two top workshops in Sevres, and Quimper also had a trial copy made."

Sevres is a porcelain-making sanctuary in the western suburbs of Paris. Most of the nobles who can't afford oriental porcelain and disdain British goods will choose the products here. Quimper is the center of painted pottery in Brittany, and its main sales target is ordinary people, but the workshops here also have many unique firing techniques.

Joseph nodded with satisfaction. After all, the Royal Ordnance Factory was personally in charge of by his father, and he was quite reliable in doing things.

He asked the most concerned question again: "What about the adhesive? Does Mr. Lavoisier have any suggestions?"

"Yes, Your Highness." Martinier pointed to a large glass bottle on the table, "Mr. Lavoisier recommended this special casein glue."

"Casein glue?" Joseph looked at the beige viscous liquid in the bottle curiously.

"It is an adhesive made from milk." Martinier said hurriedly, "First, ferment the milk to remove the grease, and then add alkali, water glass, slaked lime and other substances to promote coagulation, filter..."

Joseph had never heard of adhesive made from milk, but for now he could only trust Lavoisier.

He immediately took out iron sheets, porcelain sheets and other items of different specifications from the wooden box and called the craftsmen to prepare for trial production.

He had seen a documentary introducing bulletproof inserts before, and immediately instructed the craftsmen: "Please stick the iron sheets, porcelain sheets, silk, and iron sheets together in order. Note that they must be compacted as much as possible.

"Put the silk on the outer layer, followed by the iron sheet and the porcelain sheet, and finally the silk.

"Use the iron sheet on the outermost layer, followed by the silk..."

He was unsure of the effectiveness of these 18th-century alternative materials, so he asked the craftsmen to try out five combinations according to different combinations. At the same time, each combination required the use of plates of different thicknesses and different amounts of adhesive, and a total of more than 40 test samples were produced.

It was around 3 pm that a craftsman told Joseph that the casein glue processed by heating and drying had It was dry.

Joseph took the plug, which was about the same size as the tablet computer of later generations, and tried to pull the iron and porcelain pieces to the sides.

It didn't move at all, very strong. He was relieved immediately. It seemed that this adhesive made from milk was basically usable.

He didn't know much about adhesives. In fact, casein glue has the advantages of high viscosity, fast curing speed, and strong bonding force, and it is still widely used in the 21st century.

And Lavoisier specially adjusted the manufacturing process according to his requirements to maximize the bonding strength. It is definitely impossible to break it apart by hand.
