C352 Mirror and knowledge (2/2)

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!
