Skill Building Workshop: Mold Making

Saturday & Sunday, April 9 & 10, 2022 • 10 AM–3 PM (Pacific)

Instructor: Colby Charpentier • In-person • $325

This two-day workshop will cover designing plaster molds primarily for slip casting and press molding clay. We will go over plaster mixing, hand-ladled molds, and multi-part molds. There will be a combination of demonstration and hands-on participation. Students are asked to bring a few small models and ideas. We will choose one plaster mold project per student to work on through the weekend. Some clay experience is helpful.

This workshop is beginner-friendly and open to ceramicists of all levels. In this class you will learn how to make a two part mold from an object of your choice and you will leave with your own mold. You will also learn the process of slip casting and have a chance to pour slip into already finished molds while your plaster molds are setting.

The workshop will show how to prepare and mix two different types of slip, prepare a mold for casting, cast and release, and the final clean up steps.

Tools, clay and plaster will be provided; additional materials will be available for sale.
