Abstract: 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 (9a, 9b) 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 (9a, 9b, . . . ) 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.
