GLASS CLASSES

The Crucible's glass program teaches many different methods for creating beautiful and functional objects from glass, with a focus on warm glass and coldworking. Among the most versatile of materials, you can work with glass rods directly in the flame of a torch; fuse and reshape pieces of glass by melting them in a kiln; cast glass into molds; drill, carve and cut cold glass; or use a high-temperature glory hole to heat and form glass with hand tools.
