 a skull crucible having walls that are constructed from a plurality of pipes;    a high-frequency coil for coupling electrical energy into the contents of the skull crucible; and    an inlet and an outlet of the skull crucible being arranged in a melt surface region of the glass melt, wherein the inlet and the outlet are essentially arranged lying opposite one another.    
     
     
         2 . The device according to  claim 1 , further comprising two or more skull crucibles connected in series.  
     
     
         3 . The device according to  claim 1 , further comprising a bridge barrier provided in the melt surface region.  
     
     
         4 . The device according to  claim 3 , wherein the skull crucible is mushroom-shaped and has a lower part of relatively small diameter as well as an upper part of relatively large diameter, and wherein the inlet and the outlet are connected in the upper part of the skull crucible.  
     
     
         5 . The device according to  claim 3 , further comprising two or more skull crucibles connected in series.  
     
     
         6 . The device according to  claim 1 , wherein the skull crucible is mushroom-shaped and has a lower part of relatively small diameter as well as an upper part of relatively large diameter, and wherein the inlet and the outlet are connected in the upper part of the skull crucible.  
     
     
         7 . The device according to  claim 6 , further comprising two or more skull crucibles connected in series.
