The Limited edition bronze sculpturesWhen this model is finished, a silicone paste is sprayed on. This siliconeform is called the contra-mould. This silicone mould will be reused for making each of the wax models that have to be melted for each bronze. For each bronze they make a second wax model in the silicone mould by pouring hot soft wax in the silicone mould that is supported by a layer of gypsum packed around. After the wax cools and hardens, the contra-mould of gypsum is cut open and a soft wax model of the sculpture is left. Around this second wax model a special cement mixture is poured. When the cement has hardened the whole form is heated so the soft wax model melts, leaving a hard cement mould. In this hard mould the bronze is poured in. When the bronze cools and becomes hard, the cement mould is carved off leaving a bronze sculpture. Special chiseling and polishing finishes the bronze and finally different patines are applied to obtain a certain color of the bronze. The sculptures of Michael Parkes have a very dark brown patina called 'patino classico'. This very labor and time intensive ( can take up to one month to finish one sculpture ) and therefore a very costly procedure, especially when the editions are as small as 12.
