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.

Entry-Level

Build a small propane fueled furnace capable of melting 12 lbs. of bronze or 4 lbs. of aluminum for your next project. The furnace you make in class can easily be operated by one person, measures about 16″x16″x21″ and weighs about 100 lbs. It will include the furnace chamber, burner, a crucible and crucible handling tongs, but does not include the propane tank, hose and regulator. You’ll learn how to safely operate it, and how to approach designing and building furnaces of larger capacities.
