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.
