PART-1 SCULPTING MASTER - MOLDS - WAXES - DIPPING
THE ART OF CREATING FINE BRONZES
The process is thousands of years old. Edward Colarik's fine art bronzes are produced with his personal involvement in the actual work to insure the highest quality
The first step in creating a bronze is to create a master. In this case a clay master was first made then a plaster master was made over it and re-sculpted. Silicon molds were made over the plaster master; then a fiber glass mold was created over the silicon molds. This is done to give the silicon molds rigidity.
Hot wax is poured into the reinforced silicon molds. The wax hardens. The molds are then opened. The waxes are very rough therefore need to be re-carved and polished. The waxes are cut up into smaller pieces and gates are added to give them strength.
The waxes are dipped into a solution; then dipped into glue; then dipped into a very fine sand. The pieces have to dry and harden. After the pieces have harden, they are again dipped into glue and then into a thicker sand. This is done three or four times until the pieces become hard like a rock. These new molds are known as "investment molds".
The investment molds are then placed in an warm oven where the wax melts, leaving a cavity. This is where we get the term "lost wax process".
