Once shims are put into the sculpture to create a parting line the rubber is painted on. Then each side receives the mother mold made of plaster. My hands go through a dry week as I mix each batch of plaster with my hands. When it kicks and begins to cure it does so very quickly. The means haste in putting on the coat of plaster. This is why my studio is an absolute disaster right now. Plaster is everywhere, including spots on the cabinets, the phone, the tv remote and all over me. Just a few more days of this mess. That is not a birds nest on professor Hathaway’s rubber face, it is hemp that is added to the plaster to make it strong.
