Abstract
An application method for flux-free, frit-free luster pigments based on inorganic platelet-like particles with at least one metal oxide surface coating comprises initially applying the pigments to a vitreous surface such as a vitreous enamel on a metal substrate, a vitreous glaze on a ceramic substrate, glass, or an overglaze on a glass, enameled metal or glazed ceramic substrate. The vitreous surface is in a fused or unfused state prior to the luster pigment application. The luster pigment is surface applied to the vitreous surface. Next, the surface is heated to a temperature and for a time sufficient to fix the luster pigments to the surface.
Claims37
A method of producing a durable lustrous coating on a vitreous surface of a substrate object, comprising the steps of:
- (a) applying a surface coating of a flux-free and frit-free inorganic based luster pigment to a fused vitreous surface of the object;
- and
- (b) heating the vitreous surface to a temperature and for a time sufficient to fix the luster pigment thereto so as to provide the durable lustrous coating.
A method of producing a durable lustrous coating on a vitreous surface of a glass object, comprising the steps of:
- (a) applying a surface coating of a flux-free and frit-free inorganic based luster pigment to a fused vitreous surface of the glass object;
- and
- (b) heating the vitreous surface to a temperature and for a time sufficient to fix the luster pigment thereto so as to provide the durable lustrous coating.
A method of producing a durable lustrous coating on a vitreous surface of a ceramic object, comprising the steps of:
- (a) applying a surface coating of a flux-free and frit-free inorganic based luster pigment to a fused vitreous glaze surface overlying the ceramic object;
- and
- (b) heating the vitreous glaze surface to a temperature at least about 180 degrees Fahrenheit above its softening point and for a time sufficient to fix the luster pigment thereto and to provide the durable lustrous coating.
