A method and an apparatus for the rapid melting of glasses in a skull crucible is provided. The method and apparatus introduce high-frequency energy into the contents of the crucible by means of a coil arrangement surrounding the skull crucible, in order to heat the melt, and the batch is laid and the molten glass discharged in the upper region of the crucible, and undissolved constituents of the batch are retained by means of a cooled bridge which is immersed in the melt. The glass is taken off above the coil arrangement and is fed for further processing without flowing through the coil region.

The invention claimed is: 1. A method for the rapid melting of high-purity, aggressive and/or high-melting glasses in a skull crucible, comprising: introducing high-frequency energy into the glasses in the skull crucible by a coil arrangement surrounding the skull crucible, in order to heat the glasses into molten glass; discharging the molten glass from an upper region of the skull crucible; and retaining undissolved constituents of the molten glass from a discharge arranged in the upper region by a cooled bridge which is immersed in the molten glass, wherein the cooled bridge has an angular cross section or a curved cross section, wherein the molten glass is discharged above the coil arrangement and the discharged molten glass does not flow through the coil arrangement. 2. The method as claimed in claim 1, wherein the molten glass flows out of a glass outlet into a component of the next processing stage, which is fixedly connected to the glass outlet, in a continuous process. 3. The method as claimed in claim 2, further comprising adding heat to the upper region and/or the glass outlet to heat the molten glass. 4. The method as claimed in claim 2, wherein the molten glass overflows at the glass outlet and drops downward in the form of a glass strand. 5. The method as claimed in claim 1, further comprising agitating the molten glass during melting. 6. The method as claimed in claim 1, wherein the molten glass is taken off via a plurality of outlets. 7. The method as claimed in claim 1, further comprising refining and homogenizing the molten glass. 8. The method as claimed in claim 1, further comprising feeding the molten glass directly to a shaping unit. 9. A method for the rapid melting of high-purity, aggressive and/or high-melting glasses in a skull crucible, comprising: introducing high-frequency energy into the glasses in the skull crucible by a coil arrangement surrounding the skull crucible, in order to heat the glasses into molten glass; discharging the molten glass from an upper region of the skull crucible; and retaining undissolved constituents of the molten glass in the skull crucible by a cooled bridge which is immersed in the molten glass at the upper region, wherein the cooled bridge comprises an angular cross section. 10. The method as claimed in claim 9, wherein the molten glass flows out of a glass outlet into a component of the next processing stage, which is fixedly connected to the glass outlet, in a continuous process. 11. The method as claimed in claim 10, wherein the molten glass overflows at the glass outlet and drops downward in the form of a glass strand. 12. The method as claimed in claim 10, further comprising adding heat to the upper region and/or the glass outlet to heat the molten glass. 13. The method as claimed in claim 9, further comprising agitating the molten glass during melting. 14. The method as claimed in claim 9, wherein the molten glass is taken off via a plurality of outlets. 15. The method as claimed in claim 9, further comprising refining and homogenizing the molten glass. 16. The method as claimed in claim 9, further comprising feeding the molten glass directly to a shaping unit. 17. The method as claimed in claim 9, wherein the-molten glass is discharged above the coil arrangement and the discharged molten glass does not flow through the coil arrangement. 18. A method for the rapid melting of high-purity, aggressive and/or high-melting glasses in a skull crucible, comprising: introducing high-frequency energy into the glasses in the skull crucible by a coil arrangement surrounding the skull crucible, in order to heat the glasses into molten glass; discharging the molten glass from an upper region of the skull crucible; and retaining undissolved constituents of the molten glass in the skull crucible by a cooled bridge having a curved cross section which is immersed in the molten glass. 19. The method as claimed in claim 18, wherein the molten glass is discharged above the coil arrangement and the discharged molten glass does not flow through the coil arrangement. 20. The method as claimed in claim 18, further comprising feeding the molten glass directly to a shaping unit.
