Scenes from the Molds and Sprues Class with Jena Hounshell

Sharon Zimmerman

Hosting a different kind of jewelry class is always a treat. Recently, we had Jena Hounshell in the studio, teaching a weekend workshop all about spruing your wax carvings and molding them too! It was a weekend chock full of vital skills. Jena walked us through what can be an intimidating process—one that can seem mysterious and complex—she lead the class through it step by step, and at the end, each student left with a couple of molds that they can use in their castings.

We asked students to tell us about their favorite skill that they learned:

To have more intention with wax carving - and thinking more of sprue placement.

EverythIng! It was so informational and interesting to see and learn the process first hand.

I’m interested in creating reproductions of some of my pieces. Also, just now, I’ve been starting up a company to sell my work and I plan for reproductions to be a part of my product offering. Happy coincidence!! Learning RTV instead of natural rubber. and cutting the mold were my favorite new skills.

Learning how and why some natural and found objects are always suited to the molding process, and what I can do to make them moldable.

This was a great class, even for those students who might not make their own molds in the future, learning the process was essential for them to understand the process. Fun was had by all and the process made for great discussions. Students left with tons of resources and their brains bursting with knowledge.
