Datang romantic little landlord

The envoy of Yangzhou Chaoji finally realized that he had been fooled by Li Wangyou's words just now, and was still thinking about using history as a mirror and people as a mirror, but forgot to ask Li Wangyou what he said, and what he said What is the relationship between the use of the bronze mirror?

Reminded by Li Er, the Yangzhou court envoy came back to his senses and looked at Li Wangyou: "Uncle Huxian, what you said just now is really thought-provoking, and I admire it very much. But this is different from what you said, the purpose of the bronze mirror , what does it matter? My Yangzhou tribute mirror, what's wrong?"

Li Wangyou chuckled: "Using copper as a mirror can straighten your clothes, but the key is to see clearly. But when I look at the Yangzhou tribute mirror, the mirror surface is not very clear, and the light is blurry. How can this straighten your clothes?"

What he said immediately made the Yangzhou court anxious: "Master Huxian, how dare you humiliate my Yangzhou tribute mirror like this? Just look at it, above this hall, there are no bronze mirrors tributed by states than my Yangzhou tribute mirror." Wait for clarity?"

Of course, he is not wrong in his words, there are hundreds of bronze mirrors on the main hall, Yangzhou Tribute Mirror should be the first.Not only is the workmanship exquisite, but the mirror surface is also polished the brightest.

Li Wangyou nodded: "That's right. As far as the bronze mirrors in this hall are concerned, the Yangzhou Tribute Mirror is the best. But..."

The Yangzhou court envoy rolled his eyes directly, and sure enough, it was "but" again...

He asked directly: "But what?"

"Hey, but compared with the mirror I'm going to present to His Majesty, it's too far behind."

Li Wangyou's words made the Yangzhou court envoy impatient: "Master Huxian, be careful! How dare Ru'an boast so much?"

Even Li Er who was on the side couldn't help shaking his head: "Ziyou, don't say such big words. In Chang'an City, there is really no one who is more powerful than Yangzhou craftsmen. Where do you go to make copper that is better than Yangzhou tribute mirrors?" mirror?"

Cheng Yaojin, an old man, didn't think it was a big deal to watch the excitement, so he came over and said, "Wow hahaha, Ziyou, I don't believe what you say! But since you said that, I think you have some confidence, then Quickly present the bronze mirror you presented to His Majesty, and I will judge you to see how it compares with the Yangzhou Tribute Mirror."

Cheng Yaojin's words also made the officials in the hall nod again and again, even Li Er nodded slightly, indicating that Li Wangyou could give him his bronze mirror first.

In this regard, Li Wangyou could only helplessly shrug his shoulders: "Since Uncle Cheng has said so, then my nephew will present my bronze mirror, and ask uncle and you to see how it compares to Jiang Xin Mirror."

Not long after, a shocking scene appeared.

The bronze mirrors in the Tang Dynasty were all about the same size. The largest bronze mirror unearthed in later generations, the big double fish bronze mirror, was only 43 centimeters in diameter and weighed 12 kilograms.After all, the production of bronze mirrors requires a lot of copper materials, coupled with the limitations of the manufacturing process, it is impossible to have too large a bronze mirror.

And the bronze mirror that Li Wangyou was about to present to Li Er was carried up to the main hall by several servants in the palace, but the size surprised everyone...

607 I like it very much

Several servants in the palace struggled to carry a bronze mirror covered with a red cloth that was as tall as a person into the hall, which surprised everyone.

Cheng Yaojin was dumbfounded, and it took a long time before he said: "Ziyou, this is the bronze mirror you are going to present to His Majesty? Why is it so huge?"

The Yangzhou Chaoji envoy burst out laughing: "Haha, this is the first time I have seen such a big bronze mirror, Huxian Bo is really amazing. But I don't know how to polish such a big bronze mirror?"

The most important thing to make a bronze mirror is to grind the mirror surface.

It is not easy to use materials such as lead, tin, and mercury to make mirror grinding medicine, and to manually grind the mirror surface so that the light can tell people.

This is also the reason why there will not be large-scale copper mirrors.

Moreover, due to the reason of the production material, the copper mirror will oxidize after a period of use, and the mirror surface will gradually become dull, and the image cannot be clearly seen. At this time, the mirror surface needs to be polished again.

"The mirror is originally bright, but it is dimmed by dust and dirt, and its brightness will only appear when it is rubbed." It is said that it is a copper mirror.

When the servant brought it up, the bronze mirror presented by Li Wangyou was not only square, but also surprisingly large.A mirror as tall as a person is no different in size from the later generations of full-length mirrors.

Just looking at the general shape of the bronze mirror covered with red cloth, everyone shook their heads, thinking that Li Wangyou was just messing around.

For everyone's doubts, Li Wangyou didn't explain, just smiled, stepped forward, and directly stretched out his hand to pull away the red cloth covering the bronze mirror.

When the red cloth was pulled away to reveal the real bronze mirror below, there was a sudden gasp in the Taiji hall, the momentum was so loud that Li Wangyou wondered if all the oxygen in the hall would be given by Li Er and the others instantly. Finished smoking.

And the bright mirror, the clear reflection of the image, is like a body fixation technique, instantly freezing everyone in the hall.

All the people who saw this mirror stood motionless on the spot, lost their souls, their eyes fixed on the bronze mirror, and they didn't even blink.

The hall suddenly became completely silent, and it was extremely strange.

Behind Li Er, a servant eunuch stood with the floating dust in his hand, because he was too frightened, he didn't even know the floating dust slipped from his hand.

The floating dust fell to the ground and made a crisp sound, which suddenly woke everyone up.

Cheng Yaojin grabbed Li Wangyou's arm: "Zi, Ziyou, you, tell me clearly, what is this? Is it a treasure from the fairy family?"

Li Wangyou was caught by him vigorously, and he was in pain, so he hurriedly begged for mercy: "Uncle Cheng, let go, it hurts, it hurts! This is the bronze mirror that my nephew presented to His Majesty. What kind of treasure is it? Uncle Cheng, don't make trouble gone."

"It's not a treasure of the fairy family. How can there be such a clear bronze mirror?" After Cheng Yaojin finished speaking, he didn't want to go to the mirror and take a closer look at his own appearance: "Straight mother thief, my old Cheng is still special." For the first time, mother, she saw herself so clearly."

Li Er strode over, pushed Cheng Yaojin aside in front of the bronze mirror, and stood in front of the bronze mirror looking left and right.

In Li Wangyou's view, Li Er at this moment is very narcissistic like a girl who goes shopping in later generations and stands in front of the dressing mirror admiring her graceful figure...

Not only Li Er and Cheng Yaojin, but all the officials in the hall rushed over one by one and stood behind Li Er, even if they could only reveal a little of their own appearance from behind Li Er's figure in the mirror, it still made everyone The big boss of the court was fascinated by it.

It's no wonder that Li Er and these bigwigs lost their composure, it's because the bronze mirror presented by Li Wangyou is too amazing.

There is almost no difference in the clarity of the full-length mirror in later generations. Where has everyone seen such an exaggerated bronze mirror?

The silver mirror can clearly reflect everyone's appearance, and even the pores on everyone's face can be seen clearly.

This bronze mirror was naturally made by Li Wangyou using the methods of later generations.

When Li Wangyou said that he wanted to make a mirror for Li Er, the beautiful boss still sneered at his whimsy.

The reason is simple, there is no glass.

In the cognition of the beautiful boss, glass is necessary to make a mirror that is as clearly visible as later generations.

But in fact, making a mirror does not necessarily require such a thing as glass.

The reason why mirrors in later generations use glass is mainly because the cost of using glass is the cheapest.

The principle of mirror imaging is very simple, the surface is smooth, and objects with the ability to reflect light refract light, using the principle of light reflection to form images.

Glass itself does not have the ability to reflect light, glass only transmits light.

Therefore, determining whether the mirror is clear and capable of imaging has nothing to do with whether glass is used or not.

The use of glass is firstly because it is cheap, secondly because of the flatness of the glass, it is easy to be coated to form a mirror surface, and thirdly because the glass itself can protect the mirror surface.

The general mirror of later generations is to add a layer of coating to reflect light on the reverse side of the glass.In fact, the mirror surface we see is the light reflected by the coating, not the glass itself.

Therefore, on the same principle, Li Wangyou only needs to apply the coating to the copper mirror, and the effect is the same.

In the early mirrors, a layer of tin foil was covered on the glass, and then mercury was poured.The mercury will dissolve the tin foil, forming tin amalgam.The tin amalgam adheres to the glass, forming a mirror surface.Finally, on the back of the mirror, brush a layer of red paint to protect the mirror surface.

When Li Wangyou was a child, the mirrors at home had red paint on the back, which was made in this way.

The same is true of the bronze mirror he dedicated to Li Er.

The difference is that instead of tin foil, he used silver.
