My system is not decent

Generally speaking, the bronze material is quite strong, and it is impossible for light to pass through the entire bronze mirror.

Even reflection is a natural phenomenon that appears on a relatively flat mirror surface;

Speaking of this, some friends may start to guess wildly. Is this bronze mirror possessed of ancient magic, or is it made by the special craftsmanship of the ancients?

To answer this question, we must first find the answer from historical materials.

According to historical records, bronze mirrors first appeared in the Warring States Period and flourished in the Western Han Dynasty.

Especially in the Han Dynasty, "mirror with ring and inscription" became a major category of bronze wares in the Western Han Dynasty;

Taking the "circle with inscription mirror" as an example, the ring-shaped inscription is generally used as the main decorative pattern, and there are single-circle inscription mirrors and double-circle inscription mirrors.

Ancient bronze mirrors can be divided into Zhaoming mirror, sunlight mirror, Qingbai mirror, Tonghua mirror, Riyouxi mirror and so on according to the content of the inscription.

Among them, the most common ones are Zhaoming and Sunlight, and most of them are small mirrors under six inches in Han ruler. So far, the number of discovered mirrors is the largest, and the distribution is also the widest.

In terms of production techniques, bronze mirrors are mostly round, and the surface is relatively smooth and flat when polished, and patterns are often cast on the back;

There are also characters and stories, flowers and butterflies, birds and beasts in the decoration on the back.

I have known for a long time that there are not many kinds of bronze mirrors in ancient China, and there are very few left today. However, I really thought that I could see so few kinds of bronze mirrors at one time.

Viewed from the back side alone, ancient mirrors of the Warring States period mostly feature geometric or animal patterns.

The key point is that, although under the craftsmanship and flower decoration, the ancient mirrors of the Han Dynasty are slightly "this is".

And for thousands of years, it has been regarded as a "divine object";

This cannot be understood as "the time of heat cooling and solidification is the same, and the thickness and curvature are different, thus forming the phenomenon of bronze light transmission";

In fact, experts have never had such a problem, but before consulting the data, they found that the ancients had already discovered the "magical" bronze mirror.

Bronze mirror is an ancient utensil made of bronze, and it is also an exquisite handicraft.

Where there are no inscriptions or figures, it is relatively thin.

The difference in curvature corresponds to the ornamentation. When the light hits the mirror surface, the reflected light from the part with smaller curvature will be more concentrated, and the projection will be darker.

Of course, modern experts have also not studied the "seeing the light of the sun" mirror, and it seems that they have uncovered the light-transmitting fog that plagued the ancients for thousands of years;

To find this very precious mirror, the first thing Chen Wenzhe thought of was not the museum.

And when I didn't study it, I thought that the bronze mirror was not a magic mirror, but a treasure.

At that point, I really have to learn from the ancients.

Moreover, the flower decorations before the Han Dynasty will become more and more complicated, and their production will naturally be more sophisticated than that in the Han Dynasty;

So it seems more "simple" to say it. In short, the research results of modern experts are roughly the same as the explanations in "Mengxi Bi Tan".

That question is a bad answer, it is difficult to replicate only in modern times, in fact, scientists have retrogressed and imitated for thousands of years;

So, it's more or less "mysterious".

Because of an accident, Chen Wenzhe discovered that there was no broken light-transmitting mirror on the Nanhe Yangluo side.

"Scientists" for thousands of years have never done any research on light-transmitting ancient mirrors.

To be more complicated, the inscriptions and patterns on the back of the "Jianri Zhiguang Mirror" are relatively thick.

This was discovered by modern experts, and it is probably just an accidental phenomenon in the casting of ancient craftsmen.

According to historical records, since the Shang and Zhou dynasties, the ancients have used polished bronze to make mirrors, which are bright enough to illuminate people, but with exquisite patterns on the back.

Further development, in addition to the circular system, rhombus shape and square shape also appeared.

Having said so little, I don't actually mean to explain that the production of bronze mirrors in the past dynasties is poor or poor.

Taking the Xiaohai Museum as an example, there are no fewer than ten thousand bronze mirrors in its current collection.

But that's not necessary at all.

In the words of experts: For a thousand years, that kind of miraculous phenomenon has attracted many scholars from all over the world.

Where the curvature is larger, the reflected light is more concentrated, and the projection is brighter, which results in brighter inscriptions or patterns appearing from the reflected image.

But there are only seven pieces that can show the light-transmitting effect, and all of them are products of the Han Dynasty.

Of course, I will definitely be able to get this restored mirror. I can only learn the craftsmanship of the ancients, and I can't even learn the top modern craftsmanship of bronze restoration.

That is something modern people have studied for a long time before they understand it.

It was very popular in the Warring States Period, and it was even more exquisite in the Han and Tang Dynasties. "Mengxi Bi Tan" records that "this is because the thin part is hot first when casting, but the back text is not thick, and the front is hot but the copper shrinks less. Although the text is on the back, the mirror surface is hidden, so it appears in the light."

I definitely want to see it, if I want to make a favor.

In the Song Dynasty, hand-held mirrors with handles also appeared.

Maybe there is no friend to ask again, is it only modern experts who discovered the light transmission effect of ancient mirrors?

Among them, the "Jianrizhiguang" mirror is the worst preserved and the effect is the most obvious.

First of all, the thickness or curvature difference of the outer surface is very small, it is difficult to detect with the naked eye, and it seems to be in a flat state at first glance;

And the top-notch ancient bronze mirror in your country, the most expensive one is said to be [-] million a side, and there is no such thing.

It is precisely because the thickness is uniform that the copper mirror produces casting stress.

The "Light of Seeing the Sun" mirror is now treasured in the Xiaohai Museum, so Chen Wenzhe can certainly use it to study it, even if I have a chance to take a look.

However, bronze mirrors that can transmit light only appeared in the Han Dynasty.

The most important thing is that people have also researched it.

When it comes to that, maybe no friends are convinced, and the experts haven't explained it yet. Besides, modern technology is far more advanced than ancient times. How could it be possible to make it?

From the mid-Eastern Han Dynasty to the Wei and Jin Dynasties, floating withered animal mirrors and portrait mirrors appeared.

For example, Shen Kuo from the Song Dynasty did not explain it in detail in my "Mengxi Bi Tan".

Moreover, elastic deformation occurs when the mirror is ground, so the curvature of the thick part is large, and the curvature of the thin part is relatively small.

But some people can use experimental methods to confirm their guesses.

In the Tang Dynasty, flat mirrors and mother-of-pearl mirrors appeared.

The amazing thing is that although experts have given a "scientific" explanation, a bronze mirror with a similar effect can still be produced with today's technology.

Unfortunately, there are no museums, so I can only find another way.

But it also shows the wisdom and superb skills of the ancient ancestors, which may not be the main reason why it is called "magic mirror";

At first, I came to a private exhibition hall, and there were not many bronze mirrors on display there.

Or to be more precise, has anyone really copied the mirror that is exactly the same as the light-transmitting ancient mirror of the Western Han Dynasty?

Apart from this, Zheng Fuguang, a scholar in the Qing Dynasty, did not have a similar explanation.

Various reasons caused my trip to Nanhe that time, and that time going out was really not in vain.

I have said everything else, but I just learned the four small fine gold crafts, which is not a small gain.
