A melting or holding furnace includes a furnace chamber surrounded by a housing. The chamber holds the melt with a maximum filling level. The furnace also has an outlet opening for transferring the melt to another container. The outlet opening is provided with a shut-off valve for dosing the emerging melt. The valve is covered by melt in normal operation. The housing is connected to a tilting device which tilts the housing in such a manner that the shut-off valve can be freed from melt for the purpose of repairing it even at a maximum filling level.
