In order, inter alia, to provide an apparatus and a process for melting inorganic substances which allow a high product quality to be obtained and the technological outlay to be reduced, the invention provides a process and an apparatus in which the volumetric ratios between a melting region and a refining region can be flexibly adapted. The process comprises the steps of adding a batch into at least one first region ( 12 ) on the feed side ( 10 ) of a scull crucible ( 1 ), heating the crucible contents ( 30 ), melting down the crucible contents ( 30 ) in the at least one first region ( 12 ) of the scull crucible ( 1 ), entry into at least one second region ( 22 ) on the discharge side ( 20 ) of the scull crucible ( 1 ), melting down and/or refining the crucible contents ( 30 ) in the at least one second region ( 22 ) of the scull crucible ( 1 ), and removing the melted-down crucible contents through at least one removal apparatus ( 25 ), with the volume on the feed side ( 10 ) and/or the discharge side ( 20 ) of the scull crucible ( 1 ) being set variably.
