Ceramic artists focus on both the technical and the artistic process of making three-dimensional forms through the use of clay or other related materials, such as plaster, masonry, concrete, or 3D printing filaments. The exploration of form is fundamental to this practice, whether it results in a unique composition of artistic expression, an artwork of utility, or an aesthetic non-functional object. Many practitioners of Ceramic Art combine the skills of sculpture and painting to create sculptural works and pottery that are hand-built or wheel-thrown before being decorated by slips or glazes and kiln fired.
