During the final stages of refinement, I “work
the light.” The clay sculpture and the model are positioned
in the sun so the light is identical on both. If the shadow is
deeper on the model than on the sculpture, I cut into the clay.
If the form of the model is picking up more light than the sculpture,
I add clay.

Have you noticed that I keep using the word “refine” rather
than “correct a mistake?" Creating a
360 degree sculpture requires the form to appear
accurate from every conceivable angle. I work round
and round and round, keeping an overall perspective.

The clay sculpture is cut apart so the mold will
be less complex. This facilitates getting an accurate
wax reproduction. A wax is poured for each casting
in the edition.

A high strength silicon mold making rubber is
brushed on each section and allowed to cure. This
rubber will pick up every detail including fingerprints.
Thin plastic dividers called shims are placed in
the rubber at predetermined division lines.

Plaster is then applied to each side of the rubber
coated clay. The plaster and rubber sections are
removed from the clay model. You now have a “negative” mold
of the “positive” original.
Liquid wax is slushed into the mold and dumped out so that a
1/4” thick coating is left in the mold.
After the wax has cooled, the mold is removed,
revealing a hollow wax reproduction of the clay
original. Seam lines and any imperfections are
dressed. Some of the removed parts such as Pat’s
lower legs will be reattached in wax.
