Pottery is the process and the product of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a potter is also called pottery (plural “potteries”). The definition of pottery, used by ASTM International, is “all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products.”[1] In art history and archaeology, especially of ancient and prehistoric periods, “pottery” often means vessels only, and sculpted figurines of the same material are called “terracottas”
