A muffle furnace or muffle oven (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 coustion, including gases and flying ash. After the development of high-temperature heating elements and widespread electrifiion in developed countries, new muffle furnaces quickly moved to electric designs.
