Ming blue-and-white porcelain of the first half of the fifteenth century shows a perfect balance between ornamental design – here a scrolling floral meander-and-wave border – and the space it occupies. The uneven, slightly blurred character of the underglaze cobalt decoration is caused by tiny bubbles in the thick glaze that distort the outlines. Wares of this type were avidly sought after in the Islamic world; such Ming porcelains inspired the design of ceramics produced at Iznik in Ottoman Anatolia.
