Plate made of heavy-bodied ceramic covered with an elegant pale green glaze in imitation of jade produced in the Longquan kilns. The plate, characterized by a short, smooth and unadorned rim, has the wall of the bowl decorated with an engraved leaf motif. Objects of this type, known in the West by the generic name of Celadon porcelain, were made of stoneware coated with a layer of translucent green or blue-green enamel, produced with iron oxide in a reducing atmosphere. The Celadon family, also cataloged with the Anglo-Saxon term of green-ware, is wide and includes various artifacts made in the most disparate locations in Central Asia (China, Japan and Korea) and South East Asia (Thailand and Vietnam). Under the Song rulers, around the 12th century, the grandiose Longquan kilns were inaugurated in China and this event gave rise to a large-scale production meant for trade routes throughout the East. For their extraordinary solidity, pleasantness to the touch and beauty, the Longquan celadon were highly appreciated both in China and in the Middle East, where they were successfully exported.
