Moldmaking and casting: Plaster Mother Mold Tutorial

This is a basic mothermold support shell for a silicone rubber mold made using white hydrocal reinforced with fiberglass matte. This is a good method for creating thin, lightweight, and durable support shells. When using this method over a brush-on urethane mold make sure a release of wax is applied to the rubber surface. For more information on the skin technique check out our DVD.
