A sealing glass composition comprises a PbO-containing glass frit, two particulate refractory fillers having controlled particle size distributions, and optionally at least one additive to prevent the chemical reduction of the PbO when the frit is fired in the presence of reducing conditions. The sealing glass composition is useful as a package sealant. It is especially useful as a solder glass for sealing a face plate portion to a funnel portion of a color television picture tube at temperatures of about 400 DEG C. A particulate glass composition for use in preparing the sealing glass composition, a sealing glass paste and methods of using the sealing glass and paste are provided.
