摘要：
The instant invention is directed to faceplate glasses for television picture tubes which, because they are essentially free from MgO, have liquidus temperatures below 800.degree. C. Such glasses consist essentially, in weight percent on the oxide basis, of:______________________________________ SiO.sub.2 58-65 Al.sub.2 O.sub.3 1-3 CaO 1-4 SrO 6-12 BaO 2-9 PbO 1-3 Na.sub.2 O 5-9 K.sub.2 O 5-12 Na.sub.2 O + K.sub.2 O 14-18 TiO.sub.2 0.3-1 CeO.sub.2 0.05-0.5 ______________________________________
