The Period of Yuan dynasty (1279-1368 AD) is an important historic time for both cultural and material exchange between China and other countries, and also for the ceramic industry of Jingdezhen city. This book focuses on 14th century porcelain with underglaze blue painting from this period, the earliest blue-and-white porcelain of China and the world. During that time, along with its interaction with outside craftsmanship and cultures, Jingdezhen’s ceramic technology further developed and thus laid a solid foundation for the birth and development of the brilliant blue-and-white porcelain. This book reports Yuan blue-and-white porcelain newly discovered at the Luomaqiao kiln site, which were jointly excavated by archaeologists from Peking University and Jiangxi. The excavation uncovered remains of porcelain production as well as tons of fragments of various porcelain types, which span the Northern Song (960–1127) to the Qing dynasty (1644–1911).
