Liquid black rubber covers the entire sculpture of Rip. This
cures and will be the rubber mold from which the wax positive of Rip will be
taken.
The wax positive is the next step in the "lost-wax" bronze casting
procedure
A steel-reinforced plaster "mother" mold is taken
from the rubber-encased clay Rip.
This plaster mold is necessary to hold the shape of whatever material is used in
the rubber mold, whether it be plaster,
bonded bronze or - in the next phase of this process - wax.
