The value of bronze ware that rejuvenates its beauty through complex restoration methods will undoubtedly be greatly improved.

From the perspective of the museum, only the restoration of perfect bronzes can be more valuable for exhibition, appreciation and research.

These experts are like lonely masters in martial arts, with unique skills and a calm heart, and are quiet in the world.

When a bronze ware is restored, they often have a short-term sense of accomplishment and joy.

But as the work was taken away and on display, when I sat in front of a bronze ware full of dust again, huge loss and fatigue also "came arbitrarily".

Focusing on it has long been professional. Anyone who has been with bronze for 37 years can gain something, right?

Just like Chen Wenzhe, he has gained thirty-seven years of experience from others. Until now, he has taken a bronze ware and just glanced at it from a distance, and he can tell the truth or falsehood by himself.

After simple words, the depth of vision and skills are the integration of humans and cultural relics has become natural.

This is a master-level skill that is naturally obtained without cheating.

Of course, these are some restoration techniques of Dahai City and the Jing School. This time, Chen Wenzhe saw the techniques of the Southern School in this antique bronze museum.

Especially for the restoration of the bronze mirror, Chen Wenzhe has increased the breadth of technology.

Because he saw the top restoration skills on one of the antique bronze mirrors.

This imitation of broken bronze mirror is still a familiar thing, because Chen Wenzhe knew that his treasure should be hidden in the Yangluo Museum.

In 1998, when the Yangluo Museum was preparing for the "Yangluo Cultural Relics Essence Exhibition", the city's cultural relics work team transferred a batch of bronze mirrors.

One of them is a bronze mirror inlaid with gold-mounted characters from the Warring States Period. The shape and patterns are extremely rare in the local area, and they are of great ornamental and research value.

However, due to the long burial, the lens was broken by 51 pieces when it was unearthed.

The largest fragment is 10 cm long and 5 cm wide.

The smallest fragment, only 1 cm long.

Due to the serious damage, this mirror can no longer be displayed normally, which has seriously affected its research and storage work.

In order to make its body truly and completely reproduce, it must be repaired in order to fully reflect its value and truly reflect its extraordinary artistic charm.

To restore a precious cultural relic, the first thing to do is to carefully analyze and study its fragments and make a comprehensive judgment based on actual conditions.

Based on the judgment results, a detailed repair plan was formulated.

The restoration plan should take into account the situations that will occur at each step during the restoration of cultural relics.

The methods adopted must be effective and reliable and must not have any negative impact on cultural relics.

It is even more important to use cultural relics as experimental items to try some methods that do not have complete safety guarantees.

The restoration of this bronze mirror requires the development of respecting objective facts based on its own technical level, its brokenness, and the current status of the fragments.

Only in this way can the cultural relics be successfully repaired under an absolutely safe restoration plan.

Before restoring cultural relics, the first thing to do is to clean the stains on the surface.

Most of this bronze mirror is covered with earth rust among the 51 remaining fragments.

Moreover, the copper is damaged and the mineralization is serious, and the surface is covered with deep cracks.

If the method is used incorrectly during processing, the fragments are at risk of breaking again.

Therefore, be extra careful when handling it.

When cleaning, first dip degreased cotton with 95% ethanol to continuously soak the soil rust area.

After it is loose, gently remove it with a scalpel, and finally wipe it clean with a wet cotton ball.

In this way, each fragment should be processed. During the treatment, you should also carefully observe whether each fragment is infected with powdery rust.

Powdery rust is called the "terminal illness" of bronze ware. It is the product of corrosion caused by chloride in bronze ware that is constantly produced under a certain humidity environment.

After being infected by it, the corroded parts of the bronze ware will continue to expand and penetrate deeper until the entire utensil is perforated, rotted, and finally dissolved.

It is on the surface of the bronze ware, which is light green, loose and expanding.

After careful observation, fortunately, no signs of infection were found in this lens, so the next step of repair can be carried out.

After cleaning and testing the fragments, they must be spliced ​​together in advance.

According to the axiality at the fracture and the pattern on the surface of the copper mirror, after careful docking on the operation platform, it was found that six of the fragments did not belong to this mirror.

And these six pieces of fragments made up a quarter of the outer contour of another bronze mirror.

After careful verification and confirmation, the six fragments are separated and processed separately.

After the confirmed 45 fragments of this mirror are spliced ​​together, its initial characteristics are also revealed.

About one-third of the mirror body is lost, and it is made into a round shape, a round button, and a round button seat.

The outer edge of the tower is decorated with "shan" characters, and the inner and outer parts of the characters "shan" characters are decorated with 20 material beads, of which 4 of them are inlaid with gold foil.

After mastering its initial shape, you must carefully draw its appearance.

The drawing ratio is 1:1, so that the patterns in the missing pieces can be correctly inferred based on the remaining patterns, and the exact location of each fragment can be confirmed.

Accordingly, it can be joined.

There are two methods for joining the mirror.

One is soldering method, that is, the solder we usually use now to solder;

The other method is adhesive, which is to bond the cross section with adhesive.

When determining the repair plan, the adhesive method was selected after comprehensive consideration.

Because if welding is used for welding, with so many sections of this mirror and its own decaying copper, poor welding may damage the mirror body.

And it is also difficult to achieve and very satisfactory welding strength;

If adhesive is used and appropriate filling materials are used to repair the mirror body, and the surface cracks can be filled and reinforced, it can not only ensure the bonding quality, but also greatly increase the firmness of the mirror body.

More importantly, the bonding method is simple and reliable. If the material is selected properly, it can also ensure that the long-term shape remains unchanged.

After the adhesive method is established, which adhesive is used to bond these residues, so that satisfactory bonding strength can be achieved after bonding, so that the mirror can be preserved for a long time, which is very important for the selection of various adhesives.

After comprehensive review of various adhesives, it was finally selected to use epoxy adhesives produced in Guangdong Province and "502" glue for bonding.

The epoxy adhesive is packed in two-component pipes, evenly prepared when used, and cures after six hours.

Its characteristic is that it is easy to bond and firmly bond. In recent years, this adhesive has been used in many small cultural relics, and the bonding effect and strength are particularly outstanding.

"502" glue is a monocyanoacrylate adhesive among acrylic resin-based adhesives.

It has the characteristics of rapid bonding, easy to shape, good permeability, etc. It is suitable for rapid bonding of fine fragments. It is also the most commonly used and most convenient to use in cultural relics restoration.

When bonding, first place each fragment on the operating platform and place it roughly according to its respective orientation. Pay attention to the fact that the specific situation of each bonding surface must be accurately grasped during bonding.
