Patent Number Title Of Patent Date Issued
4098596 Method for preparing optical articles from hydrated glasses July 4, 1978
A glass article having an optical quality surface smoothness can be formed by molding a "silanol" glass material against a die having a molding surface which is a mirror of that required for the glass article, thereby obviating glass grinding and polishing steps. The article is prepared
4093469 Molded glass articles having bulk homogeneity and optical quality surface June 6, 1978
An optical glass article having a desired surface figure and demonstrating maximum theoretical light transmission can be prepared by forming a base anhydrous glass of defined compositional ranges, hydrating the glass, partially dehydrating the glass at a temperature above the softening p
