Although the jade is high in hardness, it is easy to break if it is accidentally. The jade is broken, and its value is greatly reduced. Of course, it is a pity. Therefore, in ancient China, there was a method of repairing damaged jade. The following is a detailed introduction for everyone.
There are five main methods of jade repair:
split into two
After some jade breaks, the designer and the engraver always analyze its original shape according to its damage, after some ingenuity, and then subtly divide it on the basis of the original, split it into two, and divide the original carving into two parts. Two or more small pieces that are independent or related to each other. Such repairs, because generally do not make a big discard, so reduce or make up for the original loss, and even the value of the repaired jade, sometimes not inferior to the original.
However, this method requires the repaired technician to have a high design ability, and the ability to innovate, and the amount of repair work is also large.
Gold and silver inlay
The method is inlaid on the damaged jade with precious metals such as gold and silver to cover the damage or connect the fracture. Since gold and silver itself is a very expensive metal, and it is often used to make a variety of decorative objects, the way of gold and silver with jade is widely accepted. In addition, in the traditional culture of our country, there are often the sayings of 'Golden Jade Edge' and 'Golden Jade'. Therefore, the repair method of gold and silver inlay is the preferred solution for jade repair.
However, due to the high price of gold and silver itself, the method of gold and silver inlay is relatively costly.
Re-repair
Generally, the damage of the jade is mostly at the angular and protruding positions, and the fracture can be covered by simple re-leveling and polishing, but generally it is easy to affect the proportion and coordination of the original shape.
A complicated repair requires re-re-creation of the original work according to the damage, and it is used to repair the high-low, fat, thin, bad, and broken. Large amount, high difficulty of innovation, but if it is really unique in creativity, it is often the most complete repair method with the overall effect being the closest to the original work.
Fracture bonding
Generally speaking, after the jade is broken, it is considered that the splitting is not cost-effective, it is not worthy, or it cannot be re-engraved. The general operation of this bonding method is: carefully clean the fracture surface first, then apply it evenly with high-efficiency adhesive (polyvinyl acetate float or epoxy resin), and then carefully align the original The part is strongly bonded, and the adhesive of the crack is extruded, and then wiped with acetone. During the process of solidifying the adhesive, it is best to fix it with tape or press it with a heavy object to avoid misalignment.
This method is somewhat efficient and maintains the original jade. The disadvantage is that it is not suitable for jade materials with high transparency, and it affects the original value of jade.
Filling
If the jade has only a few tiny breaks or ports, it can be repaired by filling the gap. Generally, talc powder is mixed with synthetic resin, applied to the missing parts, and repaired by engraving. It is also filled with a sealing wax and then smoothed with a hot knife or similar flat metal.
The advantages and disadvantages of this method are the same as for the bonding method. The original appearance of the utensils was retained, but it affected the original value. It is a helpless choice.
