Now that the rock and cougar are completed, it is time to mold them. Foundries can only cast small panels 16" x 16" so the sculpture needs to be cut or partitioned into pieces which seperate the individual mold panels.

Once the sculpture as been partitioned into sections (in this case with playing cards), then a silicon rubber is painted over the surface. Once the entire surface has been coated in silicon rubber it must be backed by a "mother mold". This is usually plaster or epoxy and holds the shape of each panel since the rubber has no structure. 

Each mother mold panel should be numbered and a map created so the foundry can later assemble the bronze panels.
