The furnace (10) has a furnace hood (16) that is positioned in a furnace base (11). The furnace hood is equipped with a combustion chamber for receiving dental restorations. A temperature sensor (20) is provided for continuously detecting the temperature of the dental restorations. A control device (30) is provided for controlling a drive element (18) which is relatively moved between the furnace hood and the furnace base, based on the temperature of the dental restoration detected by the temperature sensor. An independent claim is included for a method for controlling a furnace.
