Colorado Bronze Art Castings Mold Making, Wax Pouring and Chasing

Mold Making and Wax Pouring

Working from an original sculpted from wood, stone, clay, plaster, terra cotta, wax, etc., a rubber mold is created that is supported by a mother mold of plaster or fiberglass. Hot wax is poured into the rubber and plaster mold to create an even, uniform wax thickness of about 3/16th's of an inch. After the wax cools, it is removed from the rubber mold, leaving a highly detailed positive image of the sculpture.

Wax Chasing

Using many of the same tools the artist used to sculpt the original the wax is “chased”. This gives Art Castings a wax replica of the artists’ original sculpture. This wax replica will be used to create a bronze sculpture that will be an exact replica of the artist’s original.

SPRUING

Once the Wax Chasing is complete, sprues (wax bars) and the pouring cup is carefully attached to the wax pattern to insure the proper flow of metal and to control the metal solidification.
