The invention is directed to a method of making a water-based paint composition comprising sodium silicate, water, water-soluble base, metal oxide pigment, soda-lime-silica glass particles and at least one of a low-melting glass frit or zinc oxide. Preferably, it comprises only the low-melting glass frit and further preferably comprises surfactants and aluminum hydroxide. In another aspect, it is also directed to a method of making a formed glazing having a cured coating of the paint composition thereon.

A method of preparing a water-based paint composition, which has excellent adhesion to glass, which method comprises the steps of: (a) adding together components comprising: (i) water-soluble sodium silicate forming 20 to 45 weight percent of said composition, (ii) water forming 5 to 20 weight percent of said composition; (iii) water-soluble base in an amount sufficient to provide said composition with a pH of at least 10.5; and (iv) finely divided metal oxide powder selected from the group consisting of oxides of copper, iron, nickel, cobalt and mixtures thereof forming 20 to 45 weight percent of said composition and having in the prepared paint composition a particle size less than 7 microns; thus forming a first part of the paint composition; (b) adding into said first part of the paint composition, prior to using the paint composition: (v) particles of soda-lime-silica glass forming 10 to 55 weight percent of the composition and having a diameter in the prepared paint composition, on average, less than 20 microns and having a melting point of at least about 1700°F.; and at least one material selected from the group consisting of: (vi) low-melting glass frit powder melting below 1300°F. forming 0 to 10 weight percent of said composition and having a particle size in the prepared paint composition, on average, less than 10 microns; and (vii) zinc oxide forming 0 to 10 weight percent of said composition; and (c) ball milling all of said components together to form said paint composition.
