Pottery is the ceramic ware made by potters. Major types of pottery include earthenware, stoneware, and porcelain. The places where such wares are made are called potteries. Pottery is one of the oldest human technologies and art-forms, and remains a major industry today. Ceramic art covers the art of pottery, whether in items made for use or purely for decoration.

Pottery is made by forming a clay body into objects of a required shape and heating them to high temperatures in a kiln to induce reactions that lead to permanent changes, including increasing their strength and hardening and setting their shape. There are wide regional variations in the properties of clays used by potters and this often helps to produce wares that are unique in character to a locality. It is common for clays and other minerals to be mixed to produce clay bodies suited to specific purposes.
