A ceramic is an inorganic, nonmetallic solid material comprising metal, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., glasses). Ceramics are also more chemically resistant and can be used in wet environments where steel bearings would rust. 2  In some cases, their electricity-insulating properties may also be valuable in bearings. 3  Two drawbacks to ceramic bearings are a significantly higher cost and susceptibility to damage under shock loads.
Pottery is the ceramic material which makes up pottery wares, of which major types include earthenware, stoneware and porcelain. Creation of ceramic pottery takes place in workshops that are also called called potteries.Pottery also refers to the art or craft of a potter or the manufacture of pottery.A dictionary definition is simply objects of fired clays. Glaze fired is the final stage of some pottery making. 2  A glaze may be applied to the bisque form and the object can be decorated in several ways. 3  After this the object is glazed fired, which causes the glaze material to melt, then adhere to the object.
