C352 Mirror and knowledge

Gao Yang left. Xiao Wen looked at the dagger in his hand, then looked at the extremely blatant team that was following Gao Yang in the distance, he was completely sure that Gao Yang had already left.

Until now, Xiao Wen had never actually seen an emperor. But, the princess had already met two people — Lu Yuan and Gao Yang.

Xiao Wen knew that these two princesses had never left behind good reputations throughout history.

Lu Yuan was lustful of power, hence he was addicted to politics. For power, she could give up everything. Even after marrying Zhang Ao, her death wish had not changed. He even used his own husband and son as political bargaining chips.

Xiao Wen knew that this woman had inherited her mother's personality. Essentially, Lu Yuan and Lv Zhi were the same type of people.

However, Lu Yuan was a little different from Lv Zhi. Because her father was the emperor, and judging from the man's history, she couldn't possibly have an emperor as her husband.

Unlike Lv Zhi, she did not have an emperor as her husband. The talent that she had inherited from her mother, Lv Zhi, was unable to be displayed.

Maybe, if she was reborn in another dynasty, and had the fortune to become a queen, she could also be like Lv Zhi, a mother to the world, and become an outstanding statesman.

Her father was Liu Bang, and her mother was Lv Zhi. Family factors, coupled with feudal jurisprudence, prevented her from displaying her talents.

Lu Yuan was ambitious and capable. However, her position would determine her ambition and ability. It was a very dangerous thing.

Thus, when faced with Lu Yuan's approach and provocations, Xiao Wen would always be on his guard.

But Xiao Wen was sure that Gao Yang was a stupid girl.

Xiao Wen was not sure if Gao Yang had ever tried to negotiate with a monk. However, at least, she had not lost the right to inherit Fang Xuanling's title in the struggle for the rights to her room, and from how she was killed because of conspiracy, it could be seen that this woman's political abilities were mediocre.

But other than this, Xiao Wen was unable to confirm what kind of person Gao Yang was.

The contradictions recorded in history had made this woman an enigmatic existence. At the same time, it also made Xiao Wen not dare to act rashly.

"Well, sir, how are my sisters? They're not bad, are they? It should have cost her a lot of money to give you this priceless dagger. Although it is not as valuable as the mirror you have given to Emperor of the Tang, it is still more considerate. " Sun Shangxiang knew that although Gao Yang had a lot of pocket money, if he really didn't bid for the dagger, he would probably lose a lot of money.

Obviously, Sun Shangxiang was very happy with Gao Yang's loyal actions.

But Xiao Wen shook his head and said: "Compared to the mirror, knowledge is more valuable. The mirror seemed to me worthless compared to the knowledge in my head. Compared to the knowledge that I gave to Emperor of the Tang, it was not even worth a penny. "

Mirror practice, in this era people look very difficult. But with enough craftsmen, if you want, you can customize a machine with parts at a micron error (an ancient jeweller could do that, just like the modern top-level locksmiths).

Relying on that machine, Xiao Wen could have as much glass as he wanted. If he wanted to, he could sell two or three palm sized mirrors.

Two or three mirrors, each priced at five hundred thousand silver taels, was enough to make a profit.

That was why Xiao Wen said such worthless words in the mirror.

After all, to Xiao Wen who had transmigrated from the twenty-first century, there was more than one mirror in his house. In the twenty-first century, this sort of thing doesn't require much money to buy.

To Xiao Wen, the making of mirror glass was very simple. After all, with the super library, Xiao Wen wouldn't encounter any technical problems when it came to developing his productivity.

Back when he had just transmigrated into this world, Xiao Wen had already been thinking about opening a glass or mirror factory to earn money.

But taking into account the value of the glass production technology, Xiao Wen didn't really dare to take it out. If he had dared to open the glass factory without drawing enough allies to protect him, he might not even be able to survive the next day.

"Xiao Liang, Wan'er, let me ask you." Suddenly, Xiao Wen spoke to Zhuge Liang and Shangguan Waner, showing his interest in the exam.

Xiao Wen asked: "Do you all know when this mirror appeared in the world?"

If it was an ordinary old scholar, he would probably say that this thing was made by the Yellow Emperor's wife. However, as an extremely hard-core person, Xiao Wen would naturally not lie to others like this.

Zhuge Liang was stunned for a moment, then remembered that in Professor Xiao Wen's internal affairs class, he had mentioned something about mirrors.

"In the first 4,000 to 3000 BC, mirrors made of polished copper appeared in Mesopotamia and Egypt. About 1000 years later, in the early days of China's slavery society, during the Bronze Age, which was also the Shang and Zhou Dynasties, people learned about the relationship between the composition, properties and uses of the alloys in the long term of bronze smelting and casting practice, and were able to control the ratio of copper, tin and lead artificially. "

At this moment, a person wearing craftsman's clothes suddenly walked over. He said to Xiao Wen and the others: "The ancient book 'Examiner's Record' records that there are six sets of 'gold', which is the ratio of the six types of alloy. One of them finally together: "gold, tin half, so to say the same flintlock." It was the ratio used to make the copper mirror. I originally thought that ordinary scholars wouldn't care about this kind of thing. I didn't expect that there would actually be someone who knew about it. "

Hearing this, the children present were somewhat at a loss. After all, people like Sun Shangxiang and Guan Yu had almost never received a good education from Xiao Wen.

Perhaps they could read and write, but they did not have the time to study some of the ancient books.

Therefore, Xiao Wen explained to them that this "Mirror" was a mirror. Its tin content was relatively high because the copper mirror had grinded out bright surfaces and a silver-white luster.

However, before Qin Guan, Hua Xia had produced a beautiful "light mirror" that reflected the beautiful pattern on the back of the bronze mirror.

This fully illustrates the ancient Chinese excellent mirror making technology and the deep understanding of the light reflection characteristics.

At the same time, Anthony added, "In ancient Greece and Rome, Europeans also used a slightly protruding polished metal disk as a mirror. They carved patterns on its unreflective side, and the earliest mirror was a hand mirror with a handle. By the first century AD, a full-length mirror had appeared in Europe.

In fact, some parts of Europe, such as Venice and Florence and Genoa, were already in the late Middle Ages and could be said to be the richest places in Europe.

In those places, small mirrors in delicate ivory boxes or precious metal boxes become objects that women carry with them.

Just then, Xiao Wen suddenly asked: "May I know who you are?"

"Tang Mo and Tian Wang. I'm the seventh oldest in my family. Everyone calls me Tian Qi."

Tian Wang? This did not seem to be a person who had left a name in history. However, it was the Mo Clan after all. The Mo Clan in the Tang Dynasty had already been submerged in the river of history. However, in this world, the Mo family could do as they pleased during the Spring and Autumn War.

However, in other countries, there would definitely be some minor characters that had not been recorded in history.

And the mirror and its frame are increasingly the interior decoration.

Looking at Tian Wang, Xiao Wen cupped his hands and said: "Greetings, disciple of the Lu family, Xiao Wen."

The Lu family, was naturally Lv Buwei. Lv Buwei's students naturally had the intentions of being juniors.

Although this Mo Clan disciple's clothes were shabby, that was only the style of others. He had obviously read many books before, and knew about Lv Buwei and the trash.

He cupped his hands in respect.

However, they did not continue to talk. After all, Xiao Wen did not want to linger on this matter for too long.

There was no other way. Historically, due to the lack of production techniques, people had created mirrors that were either backward metal mirrors or more dangerous mercury-plated silver mirrors.

It was not until 1835, when the German chemist Libig invented the method of making modern mirrors, that this destructive technique was banned.

So a way to make mirrors on a large, harmless scale was as tempting as the blood of piranhas. If someone knew that he had mastered this technique, Xiao Wen couldn't guarantee that the people in this world would have such moral integrity.

Therefore, he could only conceal the technique of making mirrors.

It was just that when necessary, he would make two large mirrors to give to others in order to build a good relationship with them.

As for when he would open a factory to produce mirrors and glass to earn money?

He would probably have to wait until he could hang and beat up those who coveted his skills!
