ABSTRACT:
The surface energy of a glass article is reduced by adsorbing multivalent cations such as chromium onto a glass surface, then treating the surface with an aqueous solution of an alkali metal alkylate such as sodium stearate or oleate to strongly bond the long chain paraffinic or olefinic acid anion to the glass surface by ionic bonding of the alkylate anion to the adsorbed multivalent cation thereby rendering the glass surface non-wettable and lubricated.
