A Vevor dual-burner propane furnace that I run outdoors, with a sandy patch under the deck for casting. It has melted aluminum, copper, aluminum bronze and, as an experiment, a cut-up brake rotor. I cast in sand, and use 3D-printed patterns for lost-PLA casting.

Casting night: the furnace with its lid glowing, the tongs, and a flask ready for the pour.
