Wax Model Peggy chooses wax to create the original wax model.
Macquette Mold Rubber and plaster are applied over the original wax models.
First Step in Resizing Taking a plaster from the original wax mold, a grid is applied for a point by point depth transfer to styrofoam.
Resizing to Monumental Size The point by point transfer begins to take shape in the enlarged styrofoam figure.
Monumental Clay Clay is applied over the styrofoam and the artist re-details the clay to look like the original wax model.
Monumental Plate Molding dividing the clay surface with waxed cardboard shims, rubber and then plaster is applied into each section.

Wax Pouring Wax is poured over the rubber surface and a plate of about 1/4 inch thick is obtained.
Sprued Wax Feeder and vent tubes are attached to the wax plate using wax rods.
Shelling By dipping the wax plate into a porcelain slurry and then dusting with silica sand, a tough sand shell mold is created.
Drying the shells
Melt Out Placing the sand shell mold in an oven, the wax is melted out.
Poured Bronze Molten bronze at 2000 degrees Fahrenheit is poured into the sand shell molds.
Removing the shell from bronze The sand shell mold is removed with hammers and sandblasting.
Degating the bronze panels Using saws and cutting torches, the feeder and vent tubes, now in bronze are removed from the bronze plate.
Assembling The bronze plates are welded around a steel armature for support and to mount on the landscape.
Applying the Patina After heating with a propane torch, metallic acids are sprayed on the surface for the bronze to take on rich colors.
