The small fish on this dish were made in a mold and then attached to the surface before it was glazed. At Longquan, best known for its celadon glaze, “dragon kilns” more than 200 feet long were built into the hillsides. As many as 12,000 vessels could be fired in a single kiln chamber at one time. During the 100-year Mongol dynasty, trade in ceramics, spices, and natural resources provided income for the lavish lifestyles of the invaders. It also served to maintain their military campaigns. The Longquan kilns were required to produce extraordinary quantities of wares, which were exported to Southeast Asia, the Middle East, and even East Africa.
