Book excerpt: Despite its beauty, individuality and variety of design, the red or brown unglazed stoneware produced at Yixing in Jiangsu Province has received less attention than other branches of Chinese ceramic art. The Yixing potters have always specialized in the making of teapots, whose use became widespread during the Ming period as a result of the innovation of making tea from rolled leaves, rather than using it in the fine-ground, powdered from in which it had previously been supplied.
