My Homemade Metalcasting Furnace

On this page I highlight how I built my metal casting furnace. It’s a propane furnace capable of melting metals at up to 1,300 degrees F (°F). There are 2 major assemblies: The furnace housing and the burner. The housing is composed of a combination of fireclay, sand and cement; equally mixed in thirds.
