"Well, I'll think about it." Shang Wen thought about it.

"What do you women lack?" Shang Wen looked at Yingyu and asked.

"How do I know. I'm a martial arts woman. Yingyu said.

"Oh." Shang Wen continued to look at Yingyu and nodded.

"What are you looking at me for?" Yingyu asked.

"Look at you, look at your good looks." Shang Wen replied.

"Hey, hey. You're right. Although my Yingyu was born in martial arts, she can be regarded as a beauty. Yingyu happily stroked her hair and said.

"There it is." Shang Wen looked at Yingyu's face and suddenly exclaimed.

"Ouch, it scared the hell out of me." Yingyu complained.

"I say, what do you lack the most?" Shangwen asked.

"What?" Yingyu asked rhetorically.

"Beautiful. Gotta show it. You can really see it. Shang Wen said.

"Aren't you talking about mirrors?" Yingyu asked.

"That's right. You're using a bronze mirror. I'm going to make it. Like, the water can't be described. Anyway, just make your beauty as it sees from my eyes. Shang Wen said.

Yingyu was inadvertently said by Shang Wen. I feel a little embarrassed.

"Why, don't believe it." Shang Wen didn't look at Yingyu's expression at all.

"Letter. Of course I believe it. Yingyu replied immediately. Then he quickly sorted out his appearance with his hands.

"Then I'll start working immediately." Shang Wen said as he took his notebook and began to work.

The invention of mirrors dates back to the 16th century. The cylindrical method was used to manufacture plate glass, and at the same time, the tin amalgamation method, in which tin foil was attached to the glass with mercury, was invented, and the number of metal mirrors was gradually reduced. In the second half of the 17th century, France invented the pouring method of flat glass, and produced high-quality large glass mirrors. Mirrors and their frames are increasingly becoming interior decoration. At the end of the 18th century, large dressing mirrors were made and used on furniture. Although tin amalgamation is harmful to humans, it continued to be used until the 19th century. In 1835, the German chemist J.von Lebiger invented the electroless silver plating method, which made the application of glass mirrors more popular.

All Shang Wen had to do was make a mirror using the tin amalgam method. But for their own safety. Shangwen decided to adopt a certain isolation method to make it. It is mainly operated by a certain simple robotic arm. I don't know how this works. Shang Wen thought he could give it a try.

As for the raw materials of glass. Shang Wen can't think of any good way to do it now, so instead of this, it is better to use another method to stimulate it. That is to increase the use of glass. Encourage the glass industry to separate from other industries. For example, mirrors. eyes, and then there are some specialized instruments and equipment for manufacturing. So. It is a disguised requirement to increase the production of upstream raw materials for glass. In such high demand. Shang Wen felt that even if he didn't solve this problem. Sooner or later someone will solve this problem.

In fact, the development of the glass industry is also very related to the future development of sighting lenses and other close instruments. So, this thing has to be done. It is also necessary to stimulate its production with a high level of demand.

Just when Shangwen should have used some traditional methods to make glass. A man named Meng Chuang in Xianyang is experimenting with a new method of making glass. This man named Meng Chuang is an extremely ordinary glazier. Due to the limited number of materials. There are very few people who can go to work and make glass chips directly. This Meng Chuang is a person who finally got a job making glass pieces. However, because of the high temperature. This makes him very comfortable with the fireside working environment. So, he was quickly replaced. In this life, I have no chance to do this craft.

But this man is stubborn. You won't let me do it, I'll do it. So he quietly collected some materials. Most of these are waste products of glass. Glass factories have not yet realized the value of recycling glass for reuse. Because they have a lot of stress every day. Now the Qin State has expanded a lot of troops at once. Mass production of telescopes is required. In addition, the raw materials are tight. The process is complex, so the output has not been very high.

Meng Chuang also knows the current situation of the glass factory. He also knew. The Qin State has a law called Intellectual Property Protection. There you have this. You can get ahead yourself. So Meng Chuang devoted himself to research.

Because I can't adapt to the working environment like high temperatures. He always melts the glass before pouring it into the mold. But. Every attempt ended in failure. Because of gravity and the special material of glass. As a result, the poured glass is always of different sizes and thicknesses. Meng Chuang believes that this is the reason why he is not good enough to make molds. Or maybe there's something wrong with the material. So they experimented with wood and iron. But without exception, they all failed.

Even Meng Chuang himself felt that the success of the experiment was far away. Plus long working hours. Less time can be spent on experiments. He can only use his rest time to do experiments. The result is still a failure. Losing his patience, he smashed all his experimental equipment in a fit of rage. But this smash smashes a miracle. Originally. He just dropped a piece of tin into the pouring sink. The stove was knocked over and the sink was scorched. Melt the tin blocks. The overturned glass of water flows quickly to the sink. As a result, unexpectedly the glass of water floats on it. Seeing this scene, Meng Chuang stopped the unreasonable actions in his hands. Start paying attention to this scene.

The glass floated unexpectedly on it. This is a big discovery. So, soon Meng Chuang regrouped and began to concentrate on research.

And this is called Meng Chuang's discovery, which is a more advanced method of making glass. Float glass. than pouring. It is more suitable for large-scale production.

The forming process for float glass production is done in a tin bath where shielding gases such as nitrogen and hydrogen are fed. Under the action of gravity and surface tension, the molten glass spreads, flattens, forms a flat upper and lower surface, hardens and cools the upper and lower surfaces, and is led to the transition roller table. The roller of the roller table rotates, pulls the glass strip out of the tin bath and enters the annealing kiln, and after annealing and cutting, the flat glass product is obtained. Compared with other molding methods, the advantages of float are: it is suitable for high-efficiency manufacturing of high-quality flat glass, such as no corrugated bands, uniform thickness, flat upper and lower surfaces, and parallel to each other; The scale of the production line is not limited by the forming method, and the energy consumption per unit product is low; High utilization rate of finished products; It is easy to scientifically manage and realize the mechanization and automation of the whole line, and the labor productivity is high; The continuous operation cycle can be as long as several years, which is conducive to stable production; It can provide suitable conditions for the online production of some new varieties, such as electric float reflective glass, sprayed film glass during annealing, cold end surface treatment, etc.

These are all methods of modern craft production. And now it was discovered in an unexpected accident. It has to be said that it was an accident.
