Background Informations:
One of the five most famous locations of kilns in the Song Dysnaty of China, the Ruyao Kilns sat in Baofeng County, Henan Province, and was named after Ruzhou Perfecture, which Baofeng was part of in the Song Dynasty. The kilns uesd to produce blue galzed porcelains for imperial use. The biscuits are of the colour of incense ashes, and usually bear no painted patterns. Glazing is the main means of decoration. A finished product is glossy and blue, bearing fine crackles. The simple and fine glazing, combined with the shape of the product, forms a very graceful style, giving an impression of brightness and liveliness. The porcelains of Ruyao Kilns, hard to come by even in the Southern Song Dynasty, are very precious today, with only less than 100 of them left.
