I work from the subject and make a sketch in clay. A mold is taken from the sketch in clay. If the sculpture will be in bronze a wax cast will be made from the mold. Then I will retouch it and use it for the final mold as part of the lost wax process. The foundry will cast the sculpture. I will assist with the patina and choosing the base if needed.
For a sculpture in marble I will have a plaster made from the mold. I will retouch and refinish the plaster. From the plaster the sculpture will be copied into the marble. With different files and sand paper I will finish the sculpture.
