Pottery is the process by which ceramic materials are produced, from which ceramic art and other ceramics are made, of which major types include earthenware, stoneware and porcelain. The place where such wares are made is also called a pottery (plural "potteries"). Pottery also refers to the art or craft of the potter or the manufacture of pottery.
The definition of pottery used by ASTM is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products" (excluding things like bricks).  Some archaeologists use a different understanding of this definition by excluding ceramic objects such as figurines which are made by similar processes, materials and the same people but are not vessels.
