Pottery is the ceramic material which makes up potterywares, 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 a potter or the manufacture of pottery. A dictionary definition is simply objects of fired clays.he earliest forms of pottery were made from clays that were fired at low temperatures in pit-fires or in open bonfires. They were hand formed and undecorated. Because the biscuit form of earthenware is porous, it has limited utility for storage of liquids.
People have been making and using pottery for thousands of years. Pottery is made by moulding clay into the desired shape and baking it in a kiln. The high temperature drives out all the water, and causes chemical reactions that make the clay stronger and harder.eramics, polymers and composites. Different materials have different properties. Ceramics are hard and strong, but brittle. Polymers are strong and tough, and often flexible. Composite materials combine two or more materials. 1  1. 2  2.
