ABSTRACT:
A furnace having a body in which electrically resistive material is positioned between two electrodes so that heat can be generated by passing a current through the material. The resistive material is a mixture of carbonized plant material and a non-organic material that acts as a insulator at low temperatures and acts as a conductor or semi-conductor at high temperatures.
