Class at the Middlebury Studio School

Demonstrated by Don Perdue, Sculptor – Educator


The planning, making and casting from plaster waste molds will be covered in this workshop. In addition to demonstrating the overall process, participants will be engaged in the hands-on steps of creating mold section divider walls, mixing and applying the plaster warning & reinforcing coats, incorporating external mold reinforcing braces, opening, cleaning-out and prepping a fresh mold, pouring a plaster casting, and chipping-out a fresh casting. Attendees are encouraged to bring an example of their work in clay to discuss how to make a waste mold from it. Lists of mold making materials and suppliers will be provided along with printed copies of the step by step instructions for making a plaster waste mold. This special, in-depth demonstration/workshop will wrap up with a Q&A session.
