What you’ll learn
- A customized 1:1 or small-group workshop that takes you from zero to a complete plaster mold for slip casting—terminology, why we split molds the way we do, measuring and mixing plaster, pouring, demolding, and cleanup. This course delivers a production-oriented, end-to-end mold-making workflow, culminating in a finished mold tailored to your selected piece. your target object will be reviewed and an executable mold plan will be proposed. Complex projects may require extra sessions (always pre-approved and quoted before we proceed).
