Chapter 1534 The Customs of the Ancestors
"Wait a minute, elbow..." Xu Bangda couldn't help but be dumbfounded: "We tried the syringe, because the slurry was too thick, and it was difficult for the needle to come out of the slurry? Later, we were together Make a hole in the empty space, remove the needle and then inject."
"You never thought about it. A big needle used by veterinarians?" Zhou Zhi almost laughed to death: "Cut off a section with a small sand disc and smooth the top. It's very useful."
Xu Bangda and the students couldn't help but look at each other. They didn't care at all. Knowing that syringes are also for veterinary use, why is there so much mess in this kid’s stomach? !
However, Xu Bangda and his disciples overcame many difficulties and finally took off all the supporting silks, put the painting core on the wall, and restored Tang Yin's painting to its original state. .
The next step is to patch it up.
Another reason why this painting suffered serious problems after the first restoration was that it violated the repair rules and painted a whole piece of repaired old silk directly behind the painting core.
This method saves a lot of energy and time, and the effect is also good. Even in terms of profit, using a whole piece of old silk is still expensive, which shows that the previous owner does not know how to frame it. I was very fond of this painting and decided to make a big investment.
Of course the result is that the picture will be torn even more miserably after many years.
Now the painting heart has completed the three steps of washing, uncovering and scraping, and the rest is to patch it up.
The first thing is to repair and expose the waste.
The problem of uncovering waste is especially prominent on paper, because the paper fibers will be stuck to the paper, and uneven thickness will appear in the uncovered area.
This must be smoothed with patching paper of different thicknesses and sizes according to the size and depth of each piece of wasteland to avoid uneven brushing in the later stage.
It is even more troublesome to uncover the waste of silk. What is stuck is the warp and weft near the cracks and gaps.
After these threads are glued away, the related silk threads that were originally bound by them will become "stubble" and lose their function. Therefore, the repair of silk is different from that of paper. It must be done first. Subtract, remove these stubbles, and then add, looking for old silk whose warp and weft density, thickness, and color are very consistent with the core of the painting to fill these holes and cracks.
This is the biggest bottleneck in silk restoration today. Some of the old paper used for restoration today is still alive in the Forbidden City and the National Museum. After all, paper is much easier to preserve than silk.
However, it is almost impossible to find old silk that can be used. The current method is to clean the old silk removed from the back of the old painting, select the usable part to replenish the painting core, and then use it again The new silk is used as the life and support silk for new clothes, making the ancient paintings look shiny for decades.
This kind of repair method has actually been used for a long time. The final result is that like the current Tang Yin lens, the problem is left to future generations. The more repairs are done, the more troublesome it will be for the second one to take over.
“The unveiling of silk cannot just look at the painting core.” Xu Bangda has his own understanding of this: “From the mounting process, we should treat the painting core and the supporting silk as a whole. Just like the ancient painting Xuan Paper is made of several layers of paper pressed together. "
"If you understand it this way, if you damage the supporting silk or even further damage the core of the painting during the mounting process, it will be considered a scandal."< br>
"Of course, these are all understandings from the past." Xu Bangda finally revealed the answer: "Starting from today, we have a new way to repair our ancient silk books, because we can no longer dig at the ground and tear things apart to make up for the west. Okay, this time the Tang Yin Landscape Mirror We will use a new restoration method that no longer resembles paper, because we have restored the texture of antique calligraphy and painting silk that is almost the same as that of Song and Ming silk paintings!”
“Really? "The studio was suddenly filled with excitement. "The thing is here." Zhou Zhi pointed to the silk that Xu Bangda had been holding in his hand and said.
Xu Bangda put the antique silk that had gone through strict processes on the table, and finally said a word of praise: "Look at it, this matter is really difficult. ”
A disciple took the antique silk However, after only lightly weighing it, his expression changed a bit. He opened a booklet from the laboratory bookshelf. Inside was a book-like cardboard with a transparent lamination on the surface, and underneath the film were some silk samples. Under each sample, a card is used to indicate the origin of the silk.
Zhou Zhi also curiously put his head among a group of heads and found that the oldest sample inside actually came from the Warring States Period, and the farther back it went, the closer it was.
In fact, the method of writing and painting on silk should have originated in the pre-Qin Dynasty. Historical records record that King Mu of Zhou once painted his eight horses on silk. This was the first "Eight Horses Picture".
However, due to its age, coupled with problems such as the techniques used by ancient people to make cooked silk and the purity of alum, it is extremely difficult to preserve the silk.
It is generally believed that the earliest silk painting in China is Gu Kaizhi's "Pictures of Women's History" in the Eastern Jin Dynasty, which dates back more than 1,500 years. Unfortunately, the real object is gone, and only the Tang Dynasty copy exists. Therefore, the earliest silk painting recognized by the world is "Spring Outing" by Zhan Ziqian.
However, with some archaeological discoveries, this record has been rewritten. The "Silk Painting of Figures, Dragon and Phoenix" from the Warring States Period, unearthed from the Chu Tomb in Chenjiada Mountain, Hunan Province, became the earliest silk painting today.
But if it weren't for the special environment in the Chu tomb in Dashan of the Chen family, the silk painting would never have been preserved for so long.
The Warring States silk samples in this booklet in the restoration room probably came from this way.
Under the 80x magnifying glass, the thickness and quality of the silk were clearly revealed. Finally, the disciple turned to a page. The silk sample was only about two fingers wide and two inches long; there was an old label card underneath. On it is written "Sample of the life silk of Emperor Huizong of the Song Dynasty's "White Falcon", obtained from the restoration project in 1956. Comrade Song Xiao from the Palace Museum sent it, and Comrade Li Ruiqin from Rongbaozhai took it in. "
"Except for being too neat and uniform, the weight, thickness, density, and quality of the antique silk are the closest to this one."< br>
“How about comparing it with the Ming Dynasty?” Zhou Zhi said.
The disciple turned back a few more pages, and the picture silk samples on the album became larger and larger, and finally turned to two palm-sized samples. On the label card was: "Mingwen Zhengming's running script "Fengtian Palace Morning Poetry Scroll" life silk, Silk, restored in 1979, this sample is from Xu Comrade Bangda collected it during the restoration. The left side is the life silk, and the cracks have been repaired. The right side is the support silk. It should be remounted in the Qing Dynasty. Later, Zhou Zhi saw it and could not help but sigh. "You can see the inheritance from this thick pile." No!"
"The silks of the Song and Ming dynasties are not much different apart from their fineness, oxidation level, thickness and count." Xu Bangda introduced to Zhou Zhi: "The main reason is not that the silk weaving technology of the Ming Dynasty was not as good as before. Progress, but our tradition A trend in culture..."
"Zhuyuan Mugu!" Zhou Zhi was very happy, clasped his hands and said with a smile: "The ancestors have saved us so much trouble!"
