Coordination compounds having good stability in aqueous systems are used to treat glass surfaces at elevated temperatures, the coordination compounds being represented by the general formula Y2MX6 wherein Y is an alkali metal, hydrogen or ammonium, M is tin, titanium or zirconium and X is a halogen, generally fluorine or chlorine. The glass surfaces so treated are rendered chemical resistant and when treated by conventional cold-end coatings exhibit excellent strength, scratch resistance and chemical durability.
