The creation of a bronze sculpture involves many steps.

  1. The process begins when Marie Christine makes the clay original. Great care is taken during this step because every detail will be transferred into bronze later.
  2. When the clay model is perfect, several layers of liquid rubber is brushed onto the clay and allowed to harden, or cure.
  3. The clay-filled rubber master mold is then covered in plaster so that the rubber mold will be supported when it is filled with molten wax in the next step. The plaster shell is made in pieces so that it can be separated and the contents removed from the mother mold.
  4. The rubber mold is then removed and the clay original is released from inside the rubber. Most of the time, this destroys part or all of the clay model.
  5. The rubber mold is placed back inside the plaster shell and filled with molten wax, creating the wax master. It is this master which will provide all the detail in the final bronze casting.
  6. The wax model is cleaned and any imperfections are repaired (chased). Air bubbles are filled in and details are sharpened. Now the final casting can procede.
  7. At the foundry, the wax model is inspected and prepared for casting. Wax rods are added, which will serve as entrance passages for the molten bronze and exit passages for the air and gasses inside the mold. This is called spruing the wax.
  8. The finished wax is then painted with a plaster and silicone mixture. The process is repeated several times to build up thickness and strength. The mixture is allowed to dry in between applications, forming a shell around the wax. This is the final mold.
  9. The final mold is placed in a kiln and heated. The plaster/silicone mixture hardens and the wax melts and is vaporized (lost). This is where the term "lost wax casting" comes from.
  10. Liquid bronze is poured into the ceramic mold and allowed to cool.
  11. The ceramic mold is broken away, leaving the bronze figure, which is then cleaned and chased.
  12. The piece is then polished and a patina is applied.
