The invention relates to a meltdown device for the production of high-UV transmittive glass types, comprising a meltdown tank for a melt bath a feed opening for the supplying or laying-in of highly pure raw material for the melt bath a draw-off opening for the drawing-off of material melted in the melt tank a cover arranged above the melt tank, in which the infeed opening to the melt tank is arranged above the melt bath in the region of the cover the draw-off opening is arranged in the zone of the bottom of the melt tank a heating arrangement. The heating arrangement comprises heating elements, in particular electrodes that are arranged on the melt tank in the zone of the melt bath, as well as an agitating arrangement for stirring of the melt bath and uniform intermixing and sub-mixing into the melt of material from the mixture lying on the melt surface.
A process for the production of glasses highly transmittive in the UV range by means of a melting process carried out in a melt tank in which there is a glass melt having a melt surface, comprising:
