Ruyuan was one of the Five Great Kilns of the Song Dynasty.

The Lotus Candlestick from Ruyuan in the Northern Song Dynasty is a treasured piece of porcelain from that era, classified as imperial ware.

Renowned for its distinctive sky-blue glaze, Ruyuan porcelain is regarded as the quintessential example of celadon throughout Chinese history. The forms of Ruyuan wares are simple yet elegant, with a glaze that is richly lustrous and softly radiant—pure as jade and possessing a distinct, velvety texture reminiscent of rendered butter. The crackle patterns on the glaze are often fine, intricately arranged, and gracefully staggered, commonly referred to as “cicada-wing cracks.”
