Abstract
A method for coating a substrate with a glass-like film comprises, PA0 applying to the substrate an aqueous alcoholic solution containing a polymeric network of partially hydrolyzed metal alkoxide into which network there is incorporated finely powdered glass, whereby there is achieved on the substrate a coherent and adherent initial film; and PA0 heating said film to a temperature sufficient to melt said powdered glass component, thereby converting said initial film to a final densified film.
