A furnace in which the carborundum muffle forms a continuous floor of dimensions 15 by 20 ft has its ultimate heat-receiving surface in the form of a row of tubes above and parallel to the muffle floor. Assume that this system of refractory-backed tubes has an equal radiating power as that of a plane (also 15 by 20 ft) just immediately below it.
The difference is largely historical and semantic. A retort is simply the airtight vessel that the material to be processed is placed in. The term comes from the chemical industry. A Muffle furnace refers to the insulation and separation of the heating elements from the contents of the retort. “Muffle Furnace” is terminology that came from
