The present invention provides a new and improved coating composition for use in forming a dielectric layer upon a section of metal upon firing. The coating composition includes a glass composition, said glass composition comprising in weight percent a combined weight of BaO and SrO of from about 15% to about 75%, from about 5% to about 35% B.sub.2 O.sub.3, from about 10% to about 40% SiO.sub.2, up to about 10% Al.sub.2 O.sub.3, up to about 7% Co.sub.3 O.sub.4, up to about 20% ZnO, up to about 20% TiO.sub.2, up to about 7% P.sub.2 O.sub.5, up to about 7% CuO, up to about 7% Fe.sub.2 O.sub.3, up to about 7% NiO, a combined weight of SnO, MoO.sub.3, WO.sub.3, Sb.sub.2 O.sub.5, of up to about 20%, up to about 20% Bi.sub.2 O.sub.3, a combined weight of up to about 20% Nb.sub.2 O.sub.5, La.sub.2 O.sub.3, Y.sub.2 O.sub.3 and CeO.sub.2, up to about 5% ZrO.sub.2, up to about 20% CaO, up to about 5% MgO, up to about 2% As.sub.2 O.sub.3 and a combined weight of up to about 3% Li.sub.2 O, Na.sub.2 O and K.sub.2 O.
