Abstract
A flux composition containing as a first component: 50 to 75% by weight Bi.sub.2 O.sub.3 ; 15 to 25% by weight SiO.sub.2 ; 4 to 10% by weight B.sub.2 O.sub.3 ; 2 to 9% by weight ZnO; 1 to 4% by weight alkali oxide; and optionally as a second component a compound selected from CaO, ZrO.sub.2, MgO, SrO, Al.sub.2 O.sub.3, SnO.sub.2, TiO.sub.2, BaO, MoO.sub.3, F.sub.2 and Fe.sub.2 O.sub.3. The flux composition is typically used as a major component of a paint composition having minor portions of a pigment and liquid medium. The paint compositions are particularly suited for coating glass.
