In October 1977, local villagers in Xichuan Xiasi discovered an ancient tomb washed out by a reservoir near Longshan on the west bank of the Danjiang River.

There are many bronzes and jades scattered in the ancient tomb.

When the cultural relics workers learned of the situation, they quickly went to collect cultural relics and sent people to protect the scene.

In May 1978, archaeologists discovered that 5 large and small spring and autumn tombs were distributed in an orderly manner on the small Longshan ridge.

One of the tombs, numbered m2, was verified by experts to belong to Wang Ziwu, the son of King Zhuang of Chu, who aspired to the overlord of the Central Plains during the Spring and Autumn Period.

That is, during the period of King Chukang recorded in the literature, Yin Zigeng, the order of the state of Chu.

Chen Wenzhe is very familiar with this person, because Prince Wu Ding is also his, so can you not be familiar with him?

With the discovery of this large tomb, there will be many treasures unearthed by archaeologists.

Despite the robbery, 6089 pieces of bronze ritual vessels, musical instruments, chariot and horse vessels, jade and bone vessels were unearthed, and there were 551 pieces of large and small bronze vessels alone.

Among them, cloud-patterned copper has complex decorations and fine casting. It is the earliest lost-wax casting found in the era so far.

Jin is the eucalyptus that the ancient nobles placed on the temple to hold wine glasses and jugs during feasts or sacrifices.

Because Zhou people learned the lesson of merchants who "drunk the country with alcoholism", it meant "abstinence from drinking alcohol".

From March to April 1979, 3, scientific excavations were carried out on the Xichuan Xiasi cemetery.

A total of [-] large and medium-sized tombs, [-] small tombs, [-] chariot and horse pits, etc. were cleared out here, and more than [-] precious cultural relics were unearthed.

Among them, the most precious one is the copper ban, which has a rectangular shape as a whole, and its conception is very peculiar.

The four sides of the copper ban are decorated with transparent multi-layer cloud patterns. Under the cloud patterns, several layers of copper stalks of different thicknesses form intricate and exquisite patterns.

The inner layer uses thick and straight copper stalks as the backbone, and the middle layer of copper stalks is slightly thinner and extends from top to bottom, protruding to both sides and then bending upwards.

The copper stalks on the outer layer are the thinnest, in the shape of independent curly grasses.

The inner, middle and outer layers of copper stalks are nested with each other, but the inner layer of thick copper stalks plays the main role of supporting and restraining the body.

In the middle of the forbidden surface, leave a rectangular flat and bright plain surface.

There are 12 dragon-shaped monsters clinging around the upper part of the forbidden body, 4 on the front and back, and 2 on the left and right.

They bow their waists and curl their tails, protrude their heads and stick out their tongues, facing the center of the forbidden area, forming a scene of a group of dragons guarding them, which is very spectacular.

The lower part of the ban is 12 tiger-shaped monsters, three on each of the two long sides, one on each of the four corners and two short sides, squatting under the ban as feet, supporting the body.

This well-proportioned design, ingenious shape, and exquisite casting technology make the whole utensil full of domineering, forming a mysterious and distinct artistic effect, which is amazing.

This cloud-patterned copper ban is the earliest lost-wax casting discovered in my country.

The lost wax method is one of the three casting methods invented in ancient my country. It uses the meltability of wax to cast parts with complex structures and not easy to separate.

On January 2002, 1, the State Administration of Cultural Heritage issued the "Catalogue of the First Batch of Cultural Relics Prohibited from Exhibiting Abroad (border)", stipulating that 18 pieces (groups) of precious cultural relics were the first batch of cultural relics prohibited from going abroad (border) for exhibition, and the spring and autumn cloud pattern copper was banned as one of them.

According to literature records, the earliest use of the lost-wax process in my country was in the early Tang Dynasty, and the unearthed moiré copper ban pushed forward the history of the lost-wax process in China by 1100 years.

...

On February 2018, 2, the Spring and Autumn Cloud Pattern Bronze Ban was exhibited at the "National Treasure Special Exhibition" in the Jianting Square of the Forbidden City in Shendu.

So why is it called a national treasure besides its complicated craftsmanship?

The main reason is that the moiré copper is banned, and the whole is cast by the lost wax method.

According to the literature, the earliest time when my country used the lost wax method was in the early years of the Tang Dynasty.

Therefore, the academic circles generally believe that the lost wax process in my country originated from the Three Kingdoms of Afghanistan.

However, the unearthing of the cloud-patterned copper ban pushed forward the history of my country's lost-wax casting process by 1100 years.

Therefore, the academic circles believe that the lost wax casting process was quite mature in my country at least 2500 years ago.

In this way, it is naturally impossible for the message to come from Ah San.

Looking at the cloud pattern copper ban in front of him, Chen Wenzhe still couldn't help feeling that the production of this thing is really too complicated.

Especially around the rectangular surface and the four walls, it is made of coiled copper stalks with multiple layers of inner and outer layers and different thicknesses.

The intricate and exquisite hollow moiré pattern on it is a bit dizzying to look at;
There are also 12 dragon-shaped monsters around the forbidden body. The beasts have big horns. They open their mouths and stick out their tongues.
The four corners of the base are 12 high crowns of jewelry, with the head raised and the tongue protruded, the chest raised and the waist concave, and the tiger-shaped feet supporting the body of the raising tail supporter build the solemnity and sanctity of the bronze ban.

And such a national treasure with a complex shape, when it was discovered, the forbidden body was broken into more than ten pieces.

At that time, the copper stalk of the copper ban was broken, and the cloud pattern peeled off.

The attached beasts and seated beasts all fell off from the main body, and most of them were incomplete.

It can be said that when the copper ban was discovered at that time, it had been broken into hundreds of pieces, copper stems and copper slag, and several bags were packed.

It was just such dilapidated pieces that were eventually repaired by Mr. Wang Changqing, a senior technician of the Nanhe Museum, and several of his apprentices. It took 4 years to complete the restoration.

Through splicing, orthopedic, bonding, mould-turning, supplementary matching, and old-fashioned treatment, they finally completely restored the moiré copper ban and restored the copper ban to its original appearance.

During the restoration process, firstly a plaster mold was made with a relatively complete animal body, and then cast in tin to form two and a half animals. Depending on what was missing from the animal body, it was cut from the top to make up for it.

The top flower on the top of the head and the tail flower on the tail fall off and are broken, and it is almost impossible to find a complete one. The larger pieces are turned over and bonded.

It is a pity that the copper ban is broken to such an extent, but on the other hand, it can provide convenient conditions for observing the structure of the copper ban and studying the casting process of the copper ban.

The cloud-patterned copper ban has a peculiar shape, delicate and complicated decoration, and complex and exquisite craftsmanship. The lost-wax technology used in its casting process is the earliest physical example discovered in my country.

Its excavation is not only of great value to the study of ancient Chinese bronzes and Chu culture, but also of greater significance to the study of the history of ancient Chinese science and technology.

Of course, for Chen Wenzhe, the most important thing is to restore this national treasure so that our domestic experts can become more familiar with this bronze ware and understand its production process.

Chen Wenzhe is also very interested in the craftsmanship of this treasure, after all, its shape is too complicated and delicate.

It's just that he just used backtracking and saw the maker of this treasure.

He was not Wang Changqing, but his son.

During this period, he also saw Wang Chen follow his father, Wang Changqing, to repair the "cloud-patterned copper ban", and also repaired the Prince Wuding during the period, which can be said to be an unexpected harvest.

Chen Wenzhe really didn't expect that there would be something else to be gained from examining this imitation cloud-patterned copper ban.
