Abstract
The present invention provides a novel enamel composition and a method of using the same to decorate substrates such as a section of glass. The enamel composition comprises a solids portion and a vehicle. The solids portion includes at least one glass frit and a separate and distinct addition of silicon. The solids portion comprises from about 0.01 weight percent to about 20 weight percent metallic silicon.
Claims16
A method of decorating a glass substrate to serve as an electrically heated window, such electrically heated window having a conductive metal coating applied thereto which serves as an electrically resistive heating element, said method comprising the steps of:
- A. applying to a glass substrate an enamel composition comprising a vehicle and a solids portion, such solids portion comprising a glass frit and a separate and distinct addition of silicon (Si) metal, such solids portion comprising from about 0.01 weight percent to about 20 weight percent silicon metal;
- B. optionally drying or curing such applied enamel composition;
- C. applying a conductive metal coating over such enamel composition;
- D. optionally drying or curing such applied conductive metal coating;
- and
- E. firing such glass substrate bearing such conductive metal coating and such enamel composition.
