The present invention provides a composition for use in forming an enamel cover
coat from which baked-on foods can be removed without the need for pyrolysis or
highly alkaline cleaners. The enamel cover coat preferably exhibits no chipping
or other surface defects subsequent to a 2.0 mm Plum Jam Test and an acid resistance
of A or better according to ISO 2722. The composition according to the invention
includes a glass component including at least a first glass frit comprising a low
SiO2 glass frit. Preferably, the glass component includes a blend of
the first glass frit and at least a second glass frit. Preferably, the first glass
frit includes by weight from about 30% to about 45% P2O5,
from about 20% to about 40% Al2O3, from about 15% to about
35% Li2O+Na2O+K2O, up to about 15% B2O3,
up to about 15% MgO+CaO+SrO+BaO+ZnO, up to about 10% TiO2+ZrO2,
and up to about 10% SiO2.
