Chapter 1088 Guess
"Don't you still have questions about the rhino-picking box?" When this happened, Old Qi rolled up the "Six Volume Pages of Baiyang Qingteng" to see if his posture was ready. He took it back to the room and continued to observe it for a while: "Take it out and have a look."
"This is it." Zhou Zhi took out a brocade box, opened it and took it. Showing what’s inside: “It’s mainly the bottom that confuses people.”
The sunshine in the north is abundant in winter. This rhinoceros box has experienced natural oxidation and long-term rubbing, and has produced a strong flavor. The patina, coupled with the fine layers of paint and an occasional red silk lacquer pattern in the middle, gives it a horny texture in the sunlight, more and more like a rhinoceros horn.
One of the most valuable types of rhinoceros horns is when the rhinoceros gets old, a white core grows inside the horn, extending from the bottom to the top, which is called the "Bongtian Rhinoceros".
The processed objects also have layers of naturally growing textures sandwiched with a trace of white lines, which is very similar to the visual effect of the current rhinoceros box.
"Is this the box you are talking about?" Mr. Wang picked it up and looked at it.
There is no doubt that the door of the thing is wide. The big problem now is that the box has been repaired and there are still some old traces on it, which is a bit ridiculous.
It stands to reason that the craftsmanship of the Qing Palace Building Office can be repaired to perfection, but this box seems to have been deliberately left with some clues.
"The gold characters on the primer, regardless of workmanship and format, conform to the craftsmanship of the lacquer workshop of the Manufacturing Office." Mr. Qi spoke first: "The gold characters on the gold paint are the prescribed method for lacquer workers."
"However, this rhinoceros carving technique is sophisticated and the moiré lines are beautiful. It is more exquisite than the crabapple basin I collected." Mr. Wang rubbed the box: "The texture has been softened. It should not be something from the Qianlong Dynasty, and it can only be repaired later. The bottom is repaired, not as if there is any damage to the object itself, but more like adding a layer of paint, specifically to leave an engraved base. "
Using a magnifying glass, he carefully observed the rhino-tickling box on the bottom of the lacquer box, which had been covered up by the later work. Qi Lao asked, "Old man, are the words carved on the inside of the bottom of the rhinoceros-tickling box? Style, is it just..."
"Then it is most likely the word 'Zhang Chengzao'!" Mr. Wang slapped his thigh.
"Who is Zhang Chengzao?" When it comes to miscellaneous appraisal knowledge, Zhou Zhi is completely inadequate in front of the two old men.
"Zhang Chengzao" means Zhang Cheng, who was a famous lacquer master in Jiaxing, Zhejiang during the Yuan Dynasty. Because Jiaxing during the Yuan and Ming Dynasties had a superior geographical location and a high economic level, it became an important lacquer manufacturer in the south of the Yangtze River. As a business center, a number of famous lacquer masters such as Zhang Cheng and his sons Zhang Degang, Yang Mao and Peng Junbao emerged. ”
Qi Lao said: ""Jiaxing Prefecture Chronicles" records that 'Zhang Cheng and Yang Mao were from Yanghui, Xitang, Jiaxing, and Tihong is the most famous one.' "Gegu Yaolun" also said, 'Zhang Chengyang was born in Yanghui, Xitang, Xitang in the late Yuan Dynasty. Maotihong is the most famous, but the red is thin and not strong. It is loved by Japan, Ryukyu and Japan. This thing'."
"We have Zhang Cheng's red gardenia flower plate in the National Museum, and his red box with the picture of walking on a waterfall, and there are also private collections in the island country."
Wang Lao said: "But his rhinoceros picker is relatively It is so precious that there are only two pieces at present, one is a lacquer box with rhinoceros moire pattern, which is hidden in Anhui Museum, and one is a plate with rhinoceros moire pattern, which is kept in the Palace Museum. "
"From the knife work, decoration and lacquer color. Look, now this one is almost the same as those two. If the covered traces are the words 'Zhang Chengzao', then this is a Yuan Dynasty artifact that was stamped on the bottom by Qianlong craftsmen."
"You should have a better look," Qi Lao said. Do you guys take a closer look? ”
Everyone looked carefully again and were almost certain that there should be three characters there. The first character was indeed a left-right structure, with the starting position of the stroke being the same as the character Zhang, and the last stroke being a long stroke; the second character had a heavy stroke on the lower right. , it is not clear whether it is a reverse hook or a backstroke. The starting point of the third character and the backstroke at the bottom can be vaguely distinguished.
"If you follow the structure of the three characters 'Zhang Chengzao', it can fit in." Lin Wanqiu said: "But whether it is specific or not cannot be arbitrary."
"If you want to make a conclusion, , then we have to take X-rays." Mr. Wang said, "How about taking it to the National Museum for identification tomorrow?"
< br>"If we do X-ray, will it affect the next appraisal?" Zhou Zhi asked: "Don't you mean that one X-ray will make the carbon 14 appraisal hundreds of years longer?" "Hahaha..." Mr. Wang Le Le: "This is true, but after being X-rayed, you can no longer make carbon 14."
"Actually, it's okay to make carbon 14 first," Qi Lao said, "but you have to take samples, which will be harmful to the artifacts."
"Is there any other way?" Lin Wanqiu asked.
“There are many ways to identify the age of organic matter.” Qi Lao said: “But they all have the effect of radiation, otherwise you need to take samples of the artifacts.”
“Has anyone tried infrared in China now? Thermal imaging scan?" Zhou Zhi suddenly asked.
“What?”
Zhou Zhi heard a story in his previous life, that is, a scientist used infrared imaging technology to scan Picasso's work "The Blue Room", and found a portrait of a man wearing a bow tie under the image.
The scene in "Blue Room" is of a woman taking a bath, while infrared thermal imaging technology scanned a man with a beard, leaning slightly forward, and holding his chin with his right hand.
This is a "painting within a painting". It is possible that Picasso painted a male portrait first, and then for some unknown reason, it is most likely that the male portrait did not sell, so the painting was The Blue Room was repainted on canvas.
This situation is not an isolated case. This discovery has also led major museums to use this technology to scan their own collections, and many "pictures within paintings" have been discovered one after another.
There are similarities between painting with oil paint and covering with raw lacquer, and Zhou Zhi couldn’t help but think of this method.
"It is to scan the reflected light that is invisible to the naked eye, photograph it and adjust it to be visible to the naked eye." Zhou Zhi explained how this thing works: "For example, at night, we cannot see a person in the dark with the naked eye, but the person himself With temperature, it will release infrared rays, and infrared imaging technology can detect heat sources in the dark. "
"The stacking of different layers of paint will also cause different parts of the object to absorb and reflect thermal radiation to varying degrees. The difference should also be able to be imaged in It is reflected in the above. "
"You mean that things that cannot be distinguished by human eyes do not mean that instruments cannot distinguish these three words. You can use the instrument you mentioned, or you can see them. Out?"
"About That's what I mean, but I think it's hard to find hospitals or general scientific research institutions with this kind of equipment."
"Where can I find it? This is the capital. If you can think of it, we can probably find it. .”
"There must be one at the Institute of Optics of the Chinese Academy of Sciences, or it's the army."
"Then let's go and find out about the Chinese Academy of Sciences." Mr. Wang said: "There is the army..."
" Let me ask Mr. Ma." Yu Bin took out the big brother.
