摘要： 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 30% Al2O3, from about 10% to about 25% Li2O+Na2O+K2O, from about 5% to about 22% B2O3, up to about 15% MgO+CaO+SrO+BaO+ZnO, up to about 10% SiO2, and up to about 10% TiO2+ZrO2.
