My system is not decent

Although he didn't get much information, Chen Wenzhe determined through some clues that there should be at least one mirror in Yangluo.

As early as more than 2000 years ago, my country's bronze smelting technology had reached its peak.

Especially in the pre-Qin and Warring States period, the origin of bronze civilization, bronze products with exquisite craftsmanship emerged in an endless stream.

The uncanny advanced technology is incredible.

In archaeological excavations, there are often amazing appearances of "things that pass through", and there are also miraculous phenomena that modern science cannot explain.

However, with the gradual collapse of ritual and music after the Qin Dynasty, bronze wares gradually withdrew from the stage of history.

However, the small and practical bronze mirror suddenly emerged and became the mainstay of bronze products for more than two thousand years.

After Wei Zheng's death, Tang Taizong said a famous saying: "With copper as a mirror, you can straighten your clothes; with people as a mirror, you can understand gains and losses; with history as a mirror, you can know success and failure."

Some people may wonder, since glass mirrors have always been used, how did the ancients use copper as a mirror?

The ancients cast copper blocks with smooth shapes and uniform thickness, and then polished one side of them into a mirror surface that can shine on people, restoring the original color of the metal, so as to achieve the purpose of facing the face.

Explained in scientific language: the curvature of the thick place is large, the reflected light is relatively gathered, and the projection is slightly bright;

To be fair, at first glance, the bronze mirror seems to be different from the special bronze mirror.

Perhaps a friend who is not relieved will say, "That's nothing strange?

However, the reflected image shows the pattern on the back.

But there is a kind of "ordinary" bronze inscription, that is, "bronze mirror".

The bad thing is that the light source detours through the back, and the bronze mirror seems to be in a "hollowed out" state, which is very mysterious.

Obviously, the area without inscriptions and patterns is thicker, and the rest is thinner. Therefore, if the two thicknesses are the same, they will reflect projections with the same brightness.

Since bronze mirrors are necessary for daily life, the number of bronze mirrors unearthed in archaeological history is countless and very few.

To say that, we have to go back to the winter of 1982. Beihu ez Museum was conducting field archaeological work. A group of ancient tombs of the Han Dynasty was discovered in the depths of Sitou Mountain in Yufeng District, and a "rescue excavation" was carried out;

The light-transmitting mirror is a star model only in China, and it is also enthusiastically sought after in China.

So far, among the hundreds of thousands of bronze mirrors collected in museums all over the country, more than half a hundred have the effect of light transmission, and few of them are from the Han Dynasty.

Knowing that there is no such kind of "magic mirror" in the Han Dynasty, is Zhi Xiaojia surprised?

In order to explore the eternal mystery, experts have devoted themselves to research for several years, and finally discovered the secret of the "magic mirror".

The thinner part has less curvature, the reflected light is more concentrated, and the projection will be brighter.

Now it looks plain and strange, just a heavy hand mirror.

The kind of bronze mirror with illusion ability has been regarded as a "divine object" by the ancients for a long time.

It seems unreasonable at first glance, but the "wonderful" thing that experts say is not the light spots reflected on the surface of the copper mirror.

It looks like the pattern on the back, piercing through the past.

Moreover, the formation of ordinary elastic deformation has nothing to do with how the craftsmen polished the mirror at that time.

What's even more amazing is the inscription on the back of the mirror that reads "When you see the light of the sun, you will see the bright light in the sky".Looking back at history, the traditional "rites and music" before the Warring States period were gradually disintegrated, and the princes conquered each other, and the bronze culture, which symbolized royal power and divine power, gradually declined.

However, the miraculous appearance of the bronze mirror of the Han Dynasty made everyone present jump up, because it is not the rare and rare "light-transmitting mirror" in the legend!

It turns out that the reason why the copper mirror transmits light is that the thickness distribution is uniform.

Therefore, it cannot be said that the appearance of the "light-transmitting mirror" does not bring a little luck.

But it must be illuminated by the mirror surface, and the projection generated before reflection will have spots;

After the Han Dynasty, people's requirements for life improved, so they decorated exquisite patterns or auspicious characters on the other side of the bronze mirror.

Therefore, the light-transmitting mirror of the Han Dynasty is also known as the lowest peak of ancient "white technology"!

There is no diamond-shaped ornamentation on the back, and the four-character inscription "seeing the light of the sun, Xiaoming in the sky" is cast in the inner circle of the bronze mirror, so experts call it the mirror of "seeing the light of the sun".

Instead, it presents the patterns and inscriptions on the back of the bronze mirror, as if the light directly penetrates the bronze mirror and reflects the patterns and words on the back;

But that kind of uniform difference is very large, only a few microns, and cannot be identified with the naked eye.

Therefore, whenever a bronze mirror is unearthed in a tomb, the archaeologists are already surprised.

But the bronze mirror suddenly emerged at this time, becoming the protagonist of the bronze world;

The mirror has a diameter of 7.4 cm and a net weight of about 50 grams.

At present, tens of thousands of bronze mirrors have been discovered by archeology, which also increases their value to some extent.

It should be noted that the light source hits the front of the copper mirror, but never touches the back.

From the earliest primitive tribes until the introduction of glass mirrors in the Ming Dynasty, Chinese people have been using bronze mirrors for thousands of years to trim their makeup, dress their hair and tie their hair.

Friends who have not studied cultural relics may be familiar with bronze ware, and may even say something like "bronze ware without inscriptions is less valuable", which is indeed the case;

Of course, not every bronze mirror will obtain the light transmission effect, and that has nothing to do with the polishing process.

I haven’t mentioned it later, the number of bronze mirrors discovered so far is in the majority, and there are many with or without inscriptions, but why do experts say it is “ordinary”?

The surface of ancient copper mirrors is not as rough as today's glass mirrors, and of course there will be dark shadows where the surface is uneven and flat when reflected.

Of course, the piece in the Xiaohai City Museum is from Nanhe, but from Beihu.

However, the "magic mirrors" displayed in various small museums are national treasures that are "difficult to replicate until now".

The outer list said one side, the mirror is nearly perfect circle, with a radius of 3.7 cm, a diameter of 7.4 cm, and a net weight of about 50 grams;

That's why it is known as a "light-transmitting mirror", so what is its principle?

The archaeological team also found rare copper coins from the period of Emperor Xuan of the Han Dynasty, including eight ancient bronze mirrors.

Briefly speaking, the archeology has gained a lot, and the unearthed cultural relics are only bronzes, pottery, jade and so on.

Western countries call it a "magic mirror", but even low-tech around the world cannot reproduce the same Han Dynasty light-transmitting mirror.

However, when he pointed the light source at its front, there was no doubt that there would be no reflection.

Unfortunately, that technology has been lost since the Song Dynasty.

The reason why Chen Wenzhe traced to Nanhe was because of a grinding mirror in the Xiaohai City Museum.

Experts say that kind of phenomenon is 'wonderful', isn't it more common and less strange?

Through me, Chen Wenzhe saw the ancient tombs in Yangluo.

The magic is not that the image it reflects turned out to be the back of the bronze mirror, including inscriptions and decorations!
