Abstract

Monolithic glass members are prepared by first hydrolyzing a solution of tetraethoxysilane in alcohol with an acid medium, and then gelating in a basic medium while using acid and base mediums to form compounds that volatilize during drying and sintering the gel. Substances, if any, which in the form of oxides can form a glass with SiO.sub.2, are added after hydrolyzing and prior to gelation.
