A flux composition for ceramic color, containing no harmful heavy metal such as lead, cadmium, chromium, etc. is provided. The flux composition consists mainly of 30 to 45% of SiO2, 0 to 5% of TiO2, 4 to 10% of ZrO2, 13 to 18% of B2O3, 18 to 23% of ZnO, 0 to 3% of CaO, 12 to 15% of the total of two or three kinds of R2O selected from Na2O, K2O and Li2O, 4 to 10% of fluorine and 0 to 5% of tin oxide (% being all by weight). The composition uses no lead which has been indispensable for lower melting glasses, and exhibits superior performances difficult to afford according to conventional lower melting lead-free fluxes.
