Clay is a material that is found all over the planet. It is a naturally occurring substance and results from the breakdown of feldspar by water. Clay deposits are often found near the surface of the ground and have been used for millennia by man to create pottery. Advances in decorating and glazing techniques helped to establish pottery and ceramics as strong substances that could be used on a daily basis. As leisure time grew among ancient man, clay pots became more popular for daily use. As strong and beautiful pots and vessels became more widespread, they became an art form.
