Procedure

The reactant mixture according to the present invention comprises zinc acetate, a quantity of chromium acetyl acetonate, and a solvent. The chromium acetyl acetonate is present in an amount effective to improve the chemical durability of the zinc oxide layer produced by spraying the reactant mixture against the hot surface of the glass. Zinc acetate pyrolyzes at the surface of the glass to form a layer of zinc oxide containing a small quantity of chromium dioxide commensurate with the amount of chromium acetyl acetonate contained in the reactant mixture.
