  • Method for manufacturing an opal borosilicate glass
    Patent number: 4526603
    Abstract: The dusting and segregation of the glass batch during the manufacture of opal borosilicate glass can be reduced by adding the phosphorus values to the glass batch as phosphoric acid, and calcium values as limestone, calcium carbonate or calcium oxide.
    Type: Grant
    Filed: March 28, 1983
    Date of Patent: July 2, 1985
    Assignee: FMC Corporation
    Inventors: Richard L. Lehman, William H. Manring
  • High sodium oxide composition useful in the manufacture of glass
    Patent number: 4142907
    Abstract: A high sodium oxide composition suitable for use in the manufacture of glass and fiber glass is prepared by heating a sodium carbonate ore with a silicate or other source of glass making oxides such as clay or oil shale. The product obtained is rich in sodium, calcium and magnesium oxides and contains less than 35 weight percent SiO.sub.2. It may be substituted for soda ash in a glass batch and will reduce the fuel required in glass manufacturing.
