At Sotheby's auction in Hong Kong, a "Ru sky blue glaze sunflower washbasin in the Northern Song Dynasty" was auctioned for about 200 million Hong Kong dollars. It is three times more than the highest evaluation. It refreshes the auction record of porcelain in the Song Dynasty at that time.
This Ru sky blue glaze sunflower washbasin and a Ru collection in British Museum are a pair of wares that belong to Mrs. Clark. In 1936, the couple donated one of them to the British Museum. The other one appeared in France in 1937. It is not hard to speculate that this one would have been the Clark's collection before 1936. After Mr. Clark died in 1950, his wife kept the other one until her death in 1976. It is probable that she sold it to local antique dealers in London, and then it was sold to Longquan, Japan.
"Cocoon mountain Longquan hall" is a famous pre-war vintage shop in Japan, which once had the same fame as Zhongshan chamber. Its founder, a Japanese became the biggest merchant for buying Chinese Longquan celadon furnace in the Song Dynasty. He opened his antique shop in Japan. In order to honor buyers who bought the Chinese Longquan celadon, he named his antique shop as "Longquan". This Ru sunflower washbasin has been preserved for decades and finally made a high-profile appearance in Hong Kong Sotheby's spring auction.
The porcelain in the Song Dynasty had reached a high peak in Chinese ceramic history. There Is always a saying that "Ru kiln was the first" among the five famous kilns of "Ru, Guan, Ge, Jun and Ding". Due to the invasion of Jin people, the firing time of Ru kiln is very short. Even the people of the Southern Song Dynasty sighed that it is so rare to get one porcelain. Someone said that the existing member of Ru porcelains is only 79 pieces, and most of them have been collected in the world's largest museums. And the private collections preserved few. Ru kiln is not as rich as Ding and Jun kiln in kinds. It is commonly used in dishes, saucers and washbasins, and a few are used as bowls. Its height is about 20 centimeters commonly, not exceeding 30 centimeters. The diameters of dishes, saucers and washbasins are between 10 to16 centimeters commonly. The diameter of the sky blue glaze sunflower washbasin auctioned in 2012 is only 13.5 centimeters.
