Five hundred and ninetieth chapters people than people
The bronze ware restoration competition was held in the afternoon. After the "emotional communication" at noon, Yuan Jie suddenly stuck to Luo Tian and sat close to Luo Tian to watch the competition.
"You haven't signed up for the Bronze Group competition?" Luo Tian asked Yuan Jie: "What types of repairs are you good at?"
"Porcelain and jade are the main ones. Ancient books and ancient paintings are not very good, and the others are also average. They originally reported to the jade group, but you were hit hard by you. They lost confidence, so they withdrew from the competition." Yuan Jie is now
He talked more directly, and he didn't feel so sarcastic: "If I had known you had withdrawn from the competition, I might as well try the bronze group. Go back with the first and 100,000 yuan bonus, and my dad's face would look much better."
Businessmen generally measure value by money. Luo Tian expressed his understanding. For Yuan Jie, he did not lack the 100,000 yuan, but what he lacked was a sense of accomplishment and the warmth of being recognized.
"Look, how about the bronze ware on the stage?" Zhu Jingzhi patted Luo Tian's legs and pulled Luo Tian back from his contemplation. Luo Tian looked at the stage. Most of the bronze tripods on the stage were bronze utensils, as well as wine utensils.
The shape is smaller, and the main areas that need to be repaired include deformation and fragmentation. If you want to completely restore it to the original quaint style, you need to add a link - to make it old.
"The identification should not be difficult for these players. It mainly depends on which method they use to deal with deformation and fragmentation, and whether they will miss the old things." Luo Tian said affirmatively: "The restoration of bronze ware is not only
To address the completeness of the instrument type, we must also pay attention to restoring its quaint style."
Huang Lide nodded: "Yes, in the restoration of antiques, making old is a very important part. In order to restore its original appearance, it must be separated from the usual fakes."
The players on the field have completed the appraisal link, and most of them have entered the restoration stage. After everyone entered the grid, Luo Tiancai said: "The main problem of bronzes on the stage is deformation, the ancient bronzes unearthed.
Long-term erosion by different soils, and due to the collapse of tombs and changes in the formations, the bronze ware will be deformed to varying degrees. Before repairing it, you should first understand the casting age, alloy composition, utensil shape, etc. of the bronze ware.
You should not start rashly, thinking is more important than action.”
Yuan Jie looked at Luo Tian stupidly, swallowed after finishing his mouth: "You are so good, why don't you participate in the Bronze Group competition?"
"I'm tired, so I don't want to participate." Luo Tian's random reason sent Yuan Jie away.
"Uh." Yuan Jie had nothing to say, and sighed at the same time. Sure enough, people are different from others. Compared with others, they will make people angry.
"Not bad." Zhu Jingzhi said: "Pinxuantang has less repairs to ancient bronzes, but I also know that for bronzes with light corrosion and thin copper tires, molding can be used, tin is made into molds and divided into two pieces.
On one side is the outer mold and on the other side is the inner mold. Put the deformed copper sheet between the molds in a suitable arc, opposite to the shape of the mold, clamp the mold in the large table jaw or press on the hydraulic press
, the first pressure can restore the deformed copper sheet to one-third."
"However, it is not suitable for today's competition venue." Luo Tian said: "If the effect of using the large table jaw will not be as effective as that of a hydraulic press, I guess most players will choose the pounding method, but this will only slow down the deformed part.
If the slow outward expansion is corrected, the speed will be slower."
"That's right." Huang Lide agreed with Luo Tian's opinion: "But this only applies to bronzes with strong willfulness. If bronzes with poor texture, they can only use sawing solutions."
This is where Yuan Jie interrupted: "I know this. If you take the tripod as an example, you can first find the diameter before deformation based on the perimeter of the tripod mouth. According to this, you can design the saw seam on the deformed mouth. Generally, you can choose the saw seam.
On the fractures where the wall of the instrument is compressed and deformed, do not select parts with inscriptions and patterns, especially the shortest saw seam. You should use a hacksaw to open a seam from the inner wall of the bronze ware. The depth of the saw seam is about the thickness of the bronze ware.
Two-thirds of the two-thirds, and the remaining one-third are clamped with a vise, and the sawed pieces are first orthopedic and then spliced."
"It's not bad." Luo Tian looked at the fat man in surprise: "I didn't expect you to look fat and you're very careful." Luo Tian's words didn't look like good words. Yuan Jie groaned and didn't say anything.
"The fragment splicing of bronze ware can be spliced with welding, pin lamps and bonding, and the conservative repair method of splitting bronze ware is mostly used to use tin soldering method, which is to heat the fragments and use tin as the adhesive to make it repaired and perfect
One way to do this is to carefully observe and understand the copper ware before welding, and to operate and control whether there are inscriptions, patterns, inlays and inscriptions under the rust layer. The welding port is generally selected on the inner wall of the copper ware.
, want to know about Marco Polo antique bricks, which perfect the appearance of the surface. If the shape of the instrument is special, but it cannot be welded on the reverse side, the weld must be in a place without the pattern. Sometimes, in order to increase the overall firmness, interrupted spot welding or two-sided welding ports can be used
Large copperware uses continuous welded ports. This method has a greater opposition to bronzeware, so try to use as little as possible." Luo Tian said.
"Pinto look at bronze ware with larger shapes and bronze tripods. Because the mouth edge is simple and the shape is heavy, the welding strength is not enough with glue bonding, so you can add another pin to the mouth edge." Zhu Jingzhi also became interested.
"There are also drill joints and bonding methods. Some abnormal copper ware has patterns or paints on the outlines, and antique furniture pictures. Large-area welding is not allowed. At this time, drill joints and bonding methods can be used. Drill joints are generally used for swords.
The use of weapons such as knives, ges, and yue is mostly flat, narrow and long, and the drilling and jointing method can enhance the mechanical strength and tension of the objects. The actual operation method is: first, clean the copper rust at the cracks of the objects.
Then drill several small holes on both sides of the crack, use acetone to clean the slag, then apply epoxy resin, add nails to stabilize, align the interface and press the broken joints, and wait for solidification. Adhesion refers to the use of epoxy resin
The glue (or other adhesive) bonds the residue. The drilling and bonding method are always used together to play a particularly strong role. The drilling and bonding method is still broken but not completely
Disconnected copperware is more suitable. They can effectively connect the more urgently corroded pieces, thin copper body, and parts that cannot be welded during repair."
After saying that, Zhu Jingzhi took a deep breath: "Oh, I'm old and I almost couldn't breathe when I say so much in one go. But you see, it's so hard to just talk about it, and it's very difficult to really repair it.
I guess we'll sit here until evening today."
"Master, I have withdrawn from the competition. If I want to leave early, it's OK." Luo Tian called Zhu Jingzhi to speak out to Master. Yuan Jie's eyes almost fell off, and he could only say "uh".
