Abstract
Disclosed is an apparatus for heating smokable material to volatilize at least one component of the smokable material, the apparatus including a thermal insulator including an inner wall at least partially defining a heating zone for receiving at least a portion of an article including smokable material, wherein the inner wall includes heating material that is heatable by penetration with a varying magnetic field to heat the heating zone; an outer wall; and an insulation region bound by the inner wall and the outer wall, wherein the insulation region is evacuated to a lower pressure than an exterior of the insulation region; and a magnetic field generator for generating a varying magnetic field that penetrates the inner wall in order to heat the inner wall in use.
