Abstract
Glass products such as glass lens elements are formed by an improved direct molding process at glass viscosities in the range of 10.sup.8 -10.sup.12 poises. Selected moldable alkali aluminofluorophosphate optical glasses are pressed to an optical surface finish in air utilizing an optically smooth titanium nitride molding surface, the surface being provided, for example, as a surface coating on a stainless steel mold or on a nickel chromium alloy mold supporting an electroless nickel base coating.
