Moldmaking Classes

Molds are used to produce everything from objects of art to kitchen sinks—both as a step in unique original creations and to make multiples. When you have a three-dimensional piece to duplicate, creating the right type of mold from the original is the first step. Whether you work large or small, in metal, resin, plastic, or glass, our moldmaking classes give you a great foundation and teach you which technique and which materials to use for the best results.

Meet The Moldmaking Department Head: Billy Hiebert

Billy Hiebert began moldmaking when he received his MFA for sculpture in 1965 from CCA here in Oakland. After a few years of sculpting with metal and stone, and teaching sculpture and design, he dove into industrial processes involving molding and casting. He operated a full-time business offering model making, molding, and casting to both artists and industrial clients. Now, Billy teaches both moldmaking and stone carving at The Crucible.
