A flux composition containing as a first component: 50 to 75 % by weight Bi2O3; 15 to 25 % by weight SiO2; 4 to 10 % by weight B2O3; 2 to 9 % by weight ZnO; 1 to 4 % by weight alkali oxide; and optionally as a second component a compound selected from CaO, ZrO2, MgO, SrO, Al2O3, SnO2, TiO2, BaO, MoO3, F2 and Fe2O3. 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.
