  Verfahren zur Herstellung von Quarzglas aus Quarzsand, Kieselerde oder dgl. 



   Bisher verwendete man zur Erzeugung von Quarzlas nur Bergkristall, indem man denselben vor dem Schmelzen in kleinen Stücken auf   1000 'C erhitzte   und dann schnell in kaltes Wasser brachte. Dieses Verfahren wurde wiederholt ausgeübt, und man erreichte

  Process for the production of quartz glass from quartz sand, silica or the like.



   Up until now, quartz glass has only been used to produce rock crystal, by heating it in small pieces to 1000 ° C before melting it and then quickly placing it in cold water. This procedure was repeated and achieved

   Would one now use stole of the applied rock crystal as raw material quartz sand, silica or the like and this raw material as pure as possible

   namely the insensitivity to temperature changes, do not occur.

   Also would at Schme! zen of the sand, abundant blistering occurs.
