Abstract

746.999. Purifying glass. ZEISS-STIFTUNG. C.. [trading as JENAER GLASWERK SCHOTT & GEN.]. May 31, 1954 [Jan. 11, 1953], No. 15999/54. Class 56 A process of purifying glass is characterized in that the melt is refined in a platinum crucible which is at least partially heated by eddy currents, and when the melt has reached a given temperature a vacuum of 0.7 to 0.95 atmos. is generated above the melt.
