Abstract
Lead-free alkali metal-free bismuth-borosilicate glass compositions are disclosed. These compositions are useful in preparing glass frits which are employed in glass enamel compositions which, in turn, are used to prepare glass enamel pastes. The glass enamel pastes can be coated on non-porous substrates and fused to form decorative and functional coatings on the substrates.
