中國五大民窯——汝窯纏枝花卉蓮蓬碗
汝窯燒制的汝瓷因為其絕妙的色澤、獨特藝術價值，深得帝王歡心，有“宋瓷之冠”的美譽。汝窯又與同期官窯（河南開封）、哥窯（浙江龍泉）、鈞窯（河南禹縣）、定窯（河北曲陽）合稱“宋代五大名窯”，位居五大名窯之首。
燒窯、成瓷、成瓷缺陷的修補，做工精細，設計唯美、承藝汝瓷以“釉色層”領先，器型古樸典雅得當，光潤有度，由于汝瓷釉層厚，常有開片如魚鱗、蟬翼狀，久用之后茶色會著附于裂紋處，形成不規則的變換交錯的花紋，故而手感潤滑如脂，似玉非玉之美。
燕閑清賞箋》中提及，“汝窯，余嘗見之，實為瑪瑙末入釉，汁水瑩厚如堆脂，然汁中棕眼隱若蟹爪，其釉色有天青、粉青，還有蔥綠和天藍等。粉青為上，天藍彌足珍貴。有"雨過天晴云破處"之稱譽，釉面可視碧玉，也不為過。所有歷代青瓷應以汝窯為冠。”
Because of its exquisite color and unique artistic value, Ru porcelain fired by Ru kiln won the emperor's heart and has the reputation of "the crown of Song porcelain". Ru kiln, together with the official kilns (Kaifeng, Henan), Ge kilns (Longquan, Zhejiang), Jun kilns (Yuxian, Henan), and Ding kilns (Quyang, Hebei), collectively referred to as the "Five Famous Kilns of the Song Dynasty", ranking first among the five famous kilns.
Ruyao takes the inheritance of art as its responsibility. It uses traditional hand-made ceramics to make a ceramic with up to 13 processes, including mud digging, mud mulling, billet drawing, printing blank, repairing blank, pouring water, painting blank, glazing, Burning kiln, finished porcelain, finished porcelain defect repair, fine workmanship, beautiful design, Chengyi Ru porcelain leads by "glaze color layer", simple and elegant style, smooth and graceful, because of the thick glaze layer of Ru porcelain Fish scales and cicada wings. After a long time of use, the brown color will be attached to the cracks, forming an irregular and staggered pattern, so the feel is lubricating, like the beauty of jade and jade.
The Ouyang Xiu of the Song discussed the Ru kiln in his "Return to the Field Collection": The real beauty of the Ru kiln porcelain is glaze, not azure, but pink jade, which is what we call emerald green today. The real porcelain color of Ru porcelain is made of semi-ceramics, the vitrification is not obvious, and the body is opaque and bright. Therefore, it is not excluded that future generations discard the treasures as "pottery", so it is very rare in the world. In the "Qingbo Magazine", Zhou Hui of the Song Dynasty made a detailed account of Ru kiln. Ru porcelain wins with glaze. Contemporary celadon can not compare with the same. The authentic glaze is flooded in pure blue, pure and warm. The glaze shows a soft and subtle gloss. The opalescence of different Jun porcelains is different from that of Geyao, but a kind of luster similar to ancient jade. At that time, Ru Porcelain was the only one who offered to betrayed by the Emperor. It is now known from the literature that Ru porcelain can also be used for civilian purposes, which is by no means "civil use prohibited." A more comprehensive summary of the self-collected Ru kiln porcelain and the entire Ru kiln was mentioned in the Ming Dynasty scholar Gao Lian's "Yan Xian Qing Appreciation Notes", "Ru kiln, I tasted it, it is actually agate In the glaze, the juice is as thick as fat, but the brown eyes in the juice are like crab claws. The glaze color is azure, pink, green, and sky blue. The pink is the top, and the sky blue is precious. The reputation of "Tian Qingyun broken place", the glazed surface can be seen jasper, it is not an exaggeration. All the celadon in the past should be crowned by Ru Kiln.
金滅北宋后，汝窯也隨之消亡。其開窯時間前后只有二十年，由于燒造時間短暫，傳世亦不多，在南宋時，汝窯瓷器已經非常稀有。流傳到今的真品已不足百件，已知的僅67件半，其中臺北故宮21件，北京故宮17件，上海博物館8件，英國戴維中國藝術基金會（Percival David Foundation of Chinese Art）7件，其他散藏于美、日等博物館和私人收藏約10件，還有在中國內地零散的兩件以及某博物館里的半件。全世界收藏有汝窯瓷器的博物館不到10家。1992年一件直徑8厘米的汝窯小盤在紐約蘇富比拍賣行的一次拍賣會上以154萬美元成交。之后，在香港的一次拍賣會上，一件汝窯三犧尊更是創下5000萬港元的天價。

There are less than a hundred authentic pieces circulating today, and only 67 and a half are known, including 21 in the Forbidden City in Taipei, 17 in the Forbidden City in Beijing, 8 in the Shanghai Museum, and the Percival David Foundation of Chinese Art. There are about 10 pieces in other museums and private collections scattered in the United States and Japan. There are two pieces scattered in mainland China and half in a museum. There are less than 10 museums in the world with Ru kiln porcelain. In 1992, a small 8-cm-diameter Ru kiln was sold for $ 1.54 million at an auction at Sotheby's in New York. Afterwards, at an auction in Hong Kong, a Ruyao three sacrifices made a high price of 50 million Hong Kong dollars.
