Most have a distinctive pale "duck-egg" blue glaze, "like the blue of the sky in a clearing amongst the clouds after rain" according to a medieval connoisseur, The shapes include dishes, probably used as brush-washers, cups, wine bottles (carafes in modern terms), small vases, and censers and incense-burners.They can be considered as a particular form of celadon wares.In 2012 a Sotheby's catalogue note said "Although the exact time of the production of Ru ware is still under debate, all scholars agree that it was made for an extremely short period only.Generally a space of some twenty years is proposed, from 1086 to 1106, although some scholars have argued for a slightly longer period." Shortly after Huizong abdicated the Northern Song period was ended by invaders from the north, and Huizong and his successor were captured in the disastrous Jin-Song wars of the 1120s.Apart from the last, these other styles would not normally be called "Ru ware", and fall within the range of other contemporary northern ceramics.The excavations also found sherds of "official" quality, but in more elaborate shapes than found among the surviving whole pieces.Ru ware represents one of the Five Great Kilns identified by later Chinese writers.The wares were reserved for the Imperial court, with according to one contemporary source only those they rejected reaching a wider market.

Although stoneware by Western criteria (not a category recognised in traditional Chinese thinking), the wares are fired at a relatively low temperature, and are far from fully vitrified, absorbing water at a "fairly high" rate.continues over the rims at top and bottom of the pieces, in contrast to the rival porcelain Ding ware, fired upturned and so with a rough unglazed rim, often covered with a band of metal.Instead Ru ware was kept off the kiln stack surface by being supported on three or five small spurs or prongs, presumably of metal, which left little unglazed oval spots called "sesame seeds" on the underside.There are a few oval "narcissus vases", which is to say planters for daffodils.Many pieces have a subtle crazed or crackled glaze, though there is some evidence that the most admired are those without this, and the effect was not deliberate.
