The dark blue glaze covering this jar derives from cobalt, an oxide ore that was later used as a pigment for blue-and-white porcelain—the development of which in the mid-fourteenth century changed the course of global ceramic history. Mines in the Henan and Gansu Provinces may have been the source for the native cobalt that first decorated funerary and trade ceramics in the eighth and ninth centuries C.E.
