Clay is a plastic material that is hand formable at room temperature.  The clay that we can shape and use to make things is generally referred to as a clay body and is a composition of various materials, including clay as a mineral.

Clay, the mineral, is the primary raw material that makes up our clay bodies and is also used in our glazes.

Clay is our main source of Alumina (Al2O3) in a glaze. It also contains Silica and chemically bound water molecules.  The formula for the clay mineral is Al2O3•2SiO2•2H2O.
