Claims
- 1. A method of forming a glass substrate with an adherent ceramic enamel coating which comprises
- applying to a glass substrate a ceramic enamel composition comprising:
- 40-80% by weight of at least one lead-free metal oxide glass frit containing precursors of Zn.sub.2 SiO.sub.4, wherein the sum of the weight percentage amounts of said precursors of Zn.sub.2 SiO.sub.4 in said lead-free metal oxide frit is less than about 35% by weight of said lead-free metal oxide frit;
- 0.05-15% by weight of a zinc silicate seed material; and
- 19-37% by weight of a pigment, wherein the sum of the weight percentage amounts of said at least one lead-free metal oxide frit, zinc silicate seed material, and pigment does not exceed 100%, and
- heating the coated glass substrate to an elevated temperature to fuse components of the ceramic enamel composition to the glass substrate.
- 2. The method of claim 1, further comprising subjecting the heated glass to a forming pressure with a die, and separating the formed glass from the die.
