Abstract
Zinc-containing, lead- and cadmium-free glass frits with a softening point of less than 510.degree. C. are disclosed. Obligatory components of the glass-frit composition are 31-50 mole % ZnO, 10-44 mole % SiO.sub.2, 11-35 mole % B.sub.2 O.sub.3 and 11-25 mole % Na.sub.2 O. The glass frits can be used as base frit for the production of decorative coating masses which can be stoved below 630.degree. C., preferably masses for the decorating of glass.
