Various methods of casting are used depending on the shape of the piece and the volume of production required. Traditionally, bench casting was done by skilled casters who manually controlled the filling of the mould using a type of liquid gun. In more recent years the casting has been fully automated and moulds are filled automatically with liquid slip at high pressure (pressure casting)or low pressure (beam casting). After the appropriate casting time excess slip is removed from the mould. The clay pieces complete their solidification before they are removed as damp clay articles ready for drying.
