Zusammenfassung:	The aim of the invention is to provide a reliable and efficient operation of a dental furnace ( 1 ) for producing compacted ceramics, comprising a hood-shaped firing chamber ( 3 ), into which a muffle ( 5 ) can be inserted and which is closed during operation by a bottom plate ( 4 ), and a pneumatic cylinder ( 10 ) whose working pressure can be adjusted by a pressure reducer is mounted on the firing chamber ( 3 ). To this end, the invention provides that at least two pressure reducers ( 9 a , 9 b) are each provided with a different working pressure or the pressure reducer is provided in the form of a proportional pressure regulator with electronically controllable different working pressures. The pressure reducers ( 9 a , 9 b, . . . ) or the proportional pressure regulator are/is coupled to a program unit, particularly to a memory card, inside of which different heating and/or compacting processes are stored.
