Foundry & Metal Casting Classes

Casting metal is a 6,000-year-old process still used in both manufacturing and fine art. The founder melts metal (usually aluminum, bronze and cast iron) in a crucible, pours it into a mold, then removes the mold material or the casting once the metal has cooled and solidified. In our classes, beginners learn the chemistry and basic steps that go into making a piece of cast metal, while advanced classes explore the intricacies of casting and metal finishing.
