FOUNDRY CLASSES
Casting metal is a 6,000-year-old process still used in both manufacturing and fine art. The founder melts metal in a crucible, pours the liquid metal into a mold, then removes the mold material or the casting once the metal has cooled and solidified. The most common metals used in fine art are aluminum, bronze and cast iron. In The Crucible's entry-level foundry classes, you will learn the chemistry and basic steps that go into making a piece of cast metal, while advanced classes further explore the intricacies of casting and metal finishing.

Foundry Fundamentals Entry-level Begin your exploration of foundry work with this step-by-step, hands-on overview of metal casting. This class introduces foundry processes, including wax work, ceramic shell, sand moldmaking, casting and finishing. You will use the lost-wax casting method (which begins with sculpting in wax) and the sand casting method (which uses a mold made from sand). You will help pour molten metal and complete several cast-metal pieces, which can be sculptures or utilitarian objects.

Finally, you'll cast your piece in bronze or aluminum. The class also covers basic metal finishing.
