Glass Casting & Coldworking
Classes taught at The Crucible
Cold glass can be carved, cut, and drilled to create gorgeous pieces with unique surface textures and shapes. Kiln cast glass allows you to turn wax sculptures into solid glass art pieces or put a relief into a solid piece of glass.
Hot Glass Sand Casting with Flameworked Components
An introduction to the exciting process of hot glass sand casting, to create solid glass sculptures. The casting process involves the creation of temporary molds, made by pressing objects into sand, and pouring a ladle of molten glass from the furnace into the mold. Students also spend time in the flame shop, creating small torch-worked glass components that can be added to the castings to create colorful and delicate details. Some experience working with flameworking or glass blowing is recommended. Students will receive information about what to bring. PREREQUISITE: Glass Beads I
Kiln Casting Glass Sculpture I
Create glass sculpture using the ancient technique of lost wax. Students will create silicon molds from found objects augmented with wax sculpting techniques to create wax positives. The positives will be invested in a refractory material and de-waxed, creating a void in the refractory, which will be filled with glass in the kiln. Students will learn contemporary mold making skills, wax manipulation, refractory and glass sciences, and kiln programming including glass casting and annealing firing schedules.
One-Day Coldworking Workshop
Join this 1-day workshop for an introduction to our glass cold shop, designed to prepare you for the Cold Shop CREATE program assessment. We will demonstrate safety, proper tooling techniques, and machine maintenance. Using glass blanks, we will also delve into the tools and techniques of sawing, drilling, carving, sandblasting, grinding and polishing, and gluing glass.
Youth Cast Glass Sculpture
Use clay and wax to create a positive form, such as a starfish, then transform it into a glass sculpture. Students learn how to sculpt wax or clay and create molds using plaster and silica. Glass will be melted into the molds in a kiln firing, resulting in a clear or colored glass object. This class will also explore surface imagery on glass through a quick sandblasted drinking glass project.
