Chapter 1423 Northern Ware
This Osaka-built cup has a cyanotic glaze and an excellent degree of vitrification. The oil drop patterns on the glaze are scattered in an oval shape, and the overall color is pure silver, with a slight golden tint. Although the diameter is not too large, the metal mirror has a strong metallic mirror effect, and there will be a layer of blue light on the surface under light. This is the finest partridge spot handed down from generation to generation.
Because it was highly valued, the Jianzhan was still in the middle of the Ming Dynasty, and its mouth was inlaid with gold by the famous people who owned it. After years of precipitation, the gold rim has become integrated with the Jianzhan, forming a golden rim. , black glaze, gold and silver drops, and iron tire aesthetic elements.
"Zhou Sang, you are so hardworking." Ono, a staff member who came to work, opened the door of the appraisal room and was greatly impressed when he saw Zhou Zhi sitting in front of the collection of cultural relics for another night.
"It's daybreak?" Zhou Zhi looked up and found that his neck was a little stiff, so he stood up and walked to a spacious place to practice Tai Chi routines to relieve his body.
"I brought you some fruit and milk tea." Xiaoye was more than ten years older than Zhou Zhi, but he was extremely polite to Zhou Zhi.
"Thank you, Mr. Xiaoye." Zhou Zhi smiled and said: "Put it on the table, I will eat it later."
"Zhou Sang's style of study is worth learning." Xiaoye put the things down, Bowing to Zhou Zhiyi: "No wonder I made such a major discovery not long after I came into contact with Jianzhan!"
"That has nothing to do with me coming into contact with Jianzhan," Zhou Zhiyi said. Zhi smiled and said: "It's because I am relatively familiar with the northern kilns in the Song and Jin Dynasties."
This is why Ono Heiji respects Zhou Zhi so much, because Zhou Zhi gave Anzhai Eiichi the porcelain collection. While doing the appraisal, I also conducted some research on the porcelain collection of the museum, especially the Jianzhan, which I usually have difficulty accessing, and invested a lot of energy in.
Then Zhou Zhi discovered another oil drop lamp in the museum's collection. It was not from the Jian kiln, but should be from the Cizhou kiln of the Jin Dynasty.
Cizhou Kiln is not far from the famous Jun Kiln and Ding Kiln in the north during the Song Dynasty. After the north fell to the Jin Dynasty, some of the kiln workers at the kiln began to disperse and brought the manufacturing technology to the surrounding areas. Cizhou Kiln then It is one of the key areas.
Cizhou kiln is most influenced by Ding kiln, and is famous for its "white ground engraving", "rust flower", "pearl ground", "white ground brown color", "white carved flower" and "black glaze carved flower" "," "pyrene pattern engraving" and other techniques are the most distinctive features of the black-glazed porcelain on white ground. There are also celadon and red and green porcelain from the Song Dynasty inherited from the Tang Sancai and similar in style.
The shapes and decorations of Cizhou kiln are popular among the people. They have a wide influence and develop rapidly. Eventually, a huge Cizhou kiln system was formed with the central kiln farm in Guantai Town, Handan City.
As a result, later Hebi Ji Kiln in Henan Province, Xiuwu Dangyang Valley Kiln, Pacun Kiln in Yu County, Quhe Kiln in Dengfeng Province, Jiexiu Kiln in Shanxi Province, Huoxian Kiln in Shanxi Province, Zibo Kiln in Shandong Province, and Gansu Province A large number of porcelains similar in style to Cizhou Kiln have been unearthed from Jizhou Kiln in Jizhou, Quanzhou Kiln in Fujian Province, and Guangyuan Kiln in Shu Province.
Therefore, until later, for a long time, Chinese porcelain still had the saying of "Jingde in the south and Pengcheng in the north".
The Cizhou kilns in the north can influence central Fujian and Shuzhong. In the same way, the Jianzhou kilns in central Fujian in the south can also influence the north.
The size, roundness, and distribution of the oil droplets on the oil drop lamp in the art museum are all extremely uniform. Compared with the other ones, there are much less changes.
After Zhou Zhi’s research, he discovered that these “oil droplets” are actually small kiln deformation areas with bubbles as the core. Such silver spots are half the size of the other iron-containing matrix glazes of the other lamps. In the melted state, the secondary reduction kiln transformation caused by ions floating on the glaze is completely different in principle.
Such patterns also lack the blue-based effect of oil droplets that can be obtained through reflection, similar to the diffraction and reflection effect of colorful oil films, but a simple reflection effect similar to "raindrops".
Zhou Zhi is very familiar with this difference. In the process of studying Jun kilns, Zhou Zhi knows that this "paradoxical" situation also exists in Song Jun, Jin Dynasty Jun kilns, Ming and Qing Jingde and Neiyu kilns imitating Jun kilns. That is the result of one kiln imitating another kiln without mastering the core technology.
When he studied the fetal bones again, Zhou Zhi suddenly felt happy. Isn’t this the familiar Cizhou kiln clay without makeup clay? !
The origin of the name Cizhou is because of the magnetite produced there. The spots on the kiln are actually related to the iron contained in the carcass. The properties of the fetal bones are different, and the spot effects are also different. Produce various changes from obsidian to oil droplets to rabbit hair.
The kiln is built with an iron tire, which is a black billet containing coarse-grained quartz and an iron content of up to about 8%. This characteristic makes some of the billets in the kiln look restored brown, but It is also due to oxidation in the middle and later stages of the kiln, so the inside of the body is still black.
The embryonic body of the Cizhou lamp can obviously imitate the Jian kiln, but because the glaze is made of black glaze ground from the northern unique piebald stone, the composition is completely different from the Jian kiln glaze body. The background color is more stable, but the blue is lighter. A lot, the overall light changes are not as rich as Jianzhan, the oil droplets are rounder, smaller, and more uniform.
Of course, Zhou Zhi's ability to discover this has little to do with the level of the island country's researchers themselves, but is determined by the different samples and research methods of the two countries.
Mainland-made wares tend to be defective and less complete, with the carcass exposed. The glaze color is mostly tortoise shell glaze, rabbit hair lines, but less oil droplets and less obsidian.
The lamps built by the island country are complete products and complete vessels, but the quantity is very rare. Almost all of them are treasures, with many sunglasses and oil droplets, but few rabbit hairs and tortoise shells.
Therefore, the islanders have studied the glaze color and glaze spots of Jianzhan more deeply, but they rarely see the dissected fetal bones. They only study the fetal feet with thick pulp, which is obviously insufficient in experience.
The mainland is just the opposite. Because there are so many remnants, the underglaze fetal bones of Song porcelain kiln mouths have been studied very thoroughly. Among the glaze colors of other kiln mouths, they are all good, except for Yaobian Tianmu and oil. High-grade jianzhan such as Di Tianmu lacks samples for in-depth study.
Although the two countries are still in the "honeymoon period", they have more cooperation in electronics and finance. In terms of culture and sports, there are more projects such as Go and table tennis, and there are many exchanges in cultural relics. They are rarely exhibited, but rarely go into academic research.
Zhou Zhi and Heiji Ono unexpectedly completed such a collaboration at the Osaka Museum of Oriental Porcelain that surprised both parties.
"Ono-kun, you stayed up all night, right? Is your thesis completed?" Zhou Zhi finished Tai Chi and sat down to eat wagashi: "What did the University of Tokyo say?"
"The results of the spectrum analysis have come out." Ono Heiji said with a smile: "With this experimental result, our paper can be sent out today."
"Zhou Sang, your inference is completely correct. That Jianzhan...well, it seems to be more accurate to name it as 'Yudropzhan'. Its soil and glaze are very close to the spectral results of Cizhou kiln and Jianzhou kiln." The spectrum results deviate greatly."
"Of course, except for the iron content of the fetal bone."
"Then I will continue to ask Mr. Ono for the next thing." Zhou Zhi smiled and said: "It's a pity that I have to go back in a few days. Otherwise, doing research with Mr. Ono would be a difficult task. Things that make people happy”
