Pottery, or ceramics, is a broad term that applies to all objects made of fine clay and the action of heat that irreversibly changes clay into pottery.
The making of a pot is a sustained creative process: the clay combinations, shapes and embellishments, glaze mixes, and the long hours of kiln firing — every element contributes to the outcome of a stoneware piece.
Each clay object is shaped by hand on a potter’s wheel, air dries for several weeks, fired the first time so it can be glazed, and then fired a second time for at least 12 hours.
Stoneware is fired at a high temperature (950º to 1300ºC) resulting in a dense, non-porous material with stone-like quality. -(ERA)
