Tuesdays & Fridays, 3:30-5:30 PDT / 6:30 – 8:30 EDT 

August 4, 7, 11, 14, 18, 21, 25 & 28

Tuesdays are demo days and Fridays are class discussions and, technical help, and troubleshooting. Participants receive recordings to watch for a 2-week window of time after the workshop ends so you do not have to be present.

Instructor:  Kala Stein

In this virtual mold making class, participants will learn production methods for making functional or sculptural vessels.  Participants will learn how to accurately mix and pour plaster and the fundamentals to make their own drop out (1 part) and multi-part molds. Core values of thoughtful design, efficiency, and sustainability will guide us through all steps. Participants should have experience working with clay but no experience with plaster is necessary.

The proper studio setup and health and safety are critical to the mold making process. To begin, participants will be provided with the correct information to set up a work space at home. Kala’s daily demonstrations will cover everything from what to consider when designing a vessel, various prototyping options (plaster, handbuilt, and thrown), and  troubleshooting potential problems before they happen.  A sequence of demos, activities, group discussions, and image-based presentations, will round out this technical workshop.

Participants will leave with a comprehensive understanding of basic plaster work for mold making, as well as a brief introduction to slip casting. If time is managed well, each participant will have multiple molds finished and some casted pieces ready to bisque by the end of the 4 weeks.

Virtual workshops are hosted by the Sonoma Ceramics staff; participants will be encouraged to ask questions using the chat forum in Zoom, and the host will communicate these questions to Kala during her demo.

All students will receive the Zoom recording of the workshop to watch at their convenience for two weeks after the workshop. 

Participants must pre-register for the workshop to get the Zoom link & tool list. Once you register, the links will be in your confirmation email.
