As a sealing composition which can seal a panel and a funnel of a color CRT at a relatively low temperature for a relatively short time, a non-crystallizing sealing glass essentially consists of PbO－ZnO－B2O3－Bi2O3－CS2O system and has a thermal expansion coefficient of 80 to 95×10-7/°C. The sealing glass can be used as a mixture with 40 to 5 volume percent of refractory filler powder. The PbO－ZnO－B2O3－Cs2O system glass consists essentially of, by weight, 65-80% of PbO, 5.5-8% of B2O3, 3-9% of ZnO, 7-22% of Bi2O3, 16% or more of ZnO +Bi2O3, 0.2-1% of SiO2,...
