A furnace in which heat is applied to the outside of a refractory chamber containing the chargeThe charge may be held in a muffle crucible retort or other enclosure that is enveloped by the hot flame gases and the heat must reach the charge by flowing through the walls of the container.
A furnace in which the heat source does not directly make contact with the material being heattreated is described as a muffle furnaceThe components are charged in a muffle and gas firing or electrical energy can be used to heat the muffle from outsideThe gas is burnt outside the muffle and the heating is effected by the hot gases.
A muffle furnace sometimes retort furnace in historical usage is a furnace in which the subject material is isolated from the fuel and all of the products of combustion including gases and flying ash.
