The Crucible’s Stoneworking classes teach the skills you will need to carve stone, sculpt it into vibrant and organic art pieces, mold it into furniture, and even cast concrete counter tops. Learn traditional hand-carving techniques and how to work with pneumatic tools, as well as how to design and shape different materials.

Adult Classes

The Crucible offers adult classes teaching different stoneworking techniques. Whether you want to learn the fundamentals of stone carving or components of different materials, The Crucible has you covered. See the complete list of stoneworking classes offered below.

Stone Working Creative Carving

Experience stone carving using traditional hand tools. With a hammer and chisel, your own creativity and imagination will slowly reveal a unique sculpture. All tools will be provided. During the first session, you will learn about selecting your stone and where to buy it. The Crucible may also have a small selection of stone you can purchase, at approximately $35 per stone. Returning students are welcome.

Stoneworking Youth Classes

We do not currently offer youth classes in our Stoneworking Department. You can see all The Crucible’s offerings for youth here.

Meet The Stoneworking 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.

Being Prepared For Your Stoneworking Class

Stoneworking classes are held in the stoneworking yard, which is outside in the front gated parking lot. Please contact us if you have any questions about accessibility and we will be happy to accommodate.

Students must arrive for class in all-natural fiber clothing, long pants, and closed-toe, closed-heel shoes with socks that protect up to the ankle. Long hair must be tied back. Nylon, polyester, spandex, or other synthetics are not allowed around machines, equipment, or processes that can produce hot fragments, sparks, or flames.

The Crucible requests students always arrive in studio safe clothing when working. Layers are encouraged as the studio can be very cold or very hot.
