Timothy Potts Sculpture

Making the bronzes

When the original sculpture is completed, it is usually cast in bronze using the ‘lost wax’ method. A mould of the sculpture is made to allow the casting of a wax copy.

The wax is then encased in a fire-proof coating. This coated wax is heated, causing the wax to be melted out or ‘lost’ and leaving a cavity in the shape of the original Artwork. Molten bronze, or other metal, is then poured into the void left by the ‘lost wax’. When the metal has begun to cool and set, the fire-proof shell is removed to reveal the bronze cast. Finally, the sculpture is hand finished and patinated.
