The MAI Foundation (the Ch'eng Yang Foundation) Collection of Chinese Yixing teapots is among the best in the world, containing rare examples from the late Ming through the early 20th century. In addition to the unadored and elegantly-shaped pots, the collection also includes superb examples of inscribed and painted pots; some were done by known artists and many commissioned for the imperial court and its officials. Each item illustrated is fully described in both Chinese and English, with prefaces by Sung Po-ch'ing and Chiang Jung, and an authoritative essay on the development of purple clay ware in the Ming and Qing dynasties.
