Abstract

An electric furnace comprising a container having electrically isolated wall segments useful for melting materials, particlularly ceramics, is disclosed. The electric fornace's side walls are constructed from electrically isolated segments, which cause electric current from a plasma torch to be concentrated on the material in the furnace to be melted rather than diverted to the walls of the furnace.
