PURPOSE:To obtain mixed glaze of colored frit glass having a low coefft. of thermal expansion, capable of being calcined at a low temp., and producing a favorable coloring effect by mixing colored frit glass contg. B2O3 as an essential component with a specified oxide. CONSTITUTION:To =90% basic composition consisting of 0-30% SiO2, 30-60% B2O3, 0-60% ZnO, 0-7% Li2O+Na2O+K2O, 10-30% MgO+CaO+SrO+ BaO, 0-30% PbO and 0-10% Al2O3 are added Fe2O3, Ca2O3, MnO and Cu2O as principal colorants by 0.5-10% in total, and =50 parts of this colored frit glass are mixed with one or more among TiPbO3, SiO2, Al2O3, 2SiO2 and ZrSiO4 as the balance. By this composition the desired mixed glaze of colored frit glass having =50X10-7cm/cm/ deg.C coefft. of thermal expansion and capable of being calcined at =700 deg.C is obtd.
