摘要： 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 point and, using an inert gas, at a pressure above the vapor pressure of water contained therein, and then molding a preformed blank of the glass against a die having a desired optical quality surface figure, the molding being under conditions sufficient to transfer the surface figure of the die to the glass. The base glass comprises, in mole percent, about 70 to 82% SiO.sub.2, 10 to 17% Na.sub.2 O and/or K.sub.2 O, and 5 to 15% of an oxide or oxides selected from ZnO and PbO. The water content of the partially dehydrated glass ranges from about 3 to 8 wt. percent and the molded glass has a substantially uniform refractive index throughout its bulk. Homogeneous distribution of the water throughout the glass bulk appears to be assured by limiting the total water content to a range at which the diffusion coefficient of the water species (H.sub.2 O, H.sup.+, and OH.sup.-) exhibits the greatest dependence on the total water concentration (i.e. the range at which the coefficient is a quasi-step function).

摘要： The present invention is concerned with the production of sodium and/or potassium hydrosilicate glass bodies. The basis of the invention resides in the hydration of anhydrous sodium and/or potassium silicate glass bodies in aqueous alcohol solutions to impart enhanced mechanical strength and thermoplastic properties thereto. The hydrating process, which permits close control to be maintained over the water content absorbed in the glass, can be carried out in liquid solutions of water and relatively short chain, i.e. up to about five carbon atoms, aliphatic alcohols or in gaseous atmospheres of such solutions. An ion exchange reaction of Li.sup.+ ions or protons with Na.sup.+ and/or K.sup.+ ions can be promoted at temperatures above the transformation range of the hydrated glass, and an exchange of K.sup.+ ions for Na.sup.+ and/or Li.sup.+ ions at temperatures below the transformation range. The invention also contemplates treating sodium and/or potassium hydrosilicate glass bodies, produced through the previous hydration of sodium and/or potassium silicate glass bodies, in a gaseous or liquid alcohol or water-alcohol mixture to impart increased strength and impact resistance thereto and alter the absorbed water content therein. The aforementioned ion exchange reactions are also applicable here.
