The Process of Creating the Sculpture
Creation of a wax model is the first step in creating a bronze sculpture. Once the original is formed, the piece is taken to a foundry to be cast. Large sculptures require portions to be cast and reassembled as one piece.
A rubber mold of the original is taken prior to casting. This step is necessary to reproduce a hollow wax of the original, to eliminate armature material that had been used in the construction of the piece, and to permit duplicate waxes for limited editions.
The hollow wax is then invested in a waste mold, with core material suspended in the space. This mold is cured in a kiln; the wax drains out of the mold leaving a hollow space into which bronze is poured. This is called the “lost wax” process.
