Mould / cast
The exact moulding of a natural or art item in materials such as gypsum, metal or wax. The process starts with producing a so-called negative form of the model. This form is then filled with the liquidised material chosen for the mould. Artists use moulds as in-between stages when creating a sculpture. Moulds also represent the desired final appearance of a piece of art. This applies especially for sculptures intended for open air display that are then cast in metal under the artists supervision. In this case, the mould is considered the original sculpture. In a narrow sense, later mouldings of original sculptures not produced by the same sculptor are called cast.
