Glass for cathode ray tube faceplates

A glass essentially free from readily reducible metal oxides, MgO, and fluorine suitable for manufacturing faceplates for cathode ray tubes which exhibits a linear coefficient of thermal expansion (0.degree.-300.degree. C.) greater than 97 but less than 100.times.10.sup.-7 /.degree.C., an annealing point of at least about 500.degree. C., a strain point of at least about 460.degree. C., a Log .rho. at 250.degree. C. greater than 9, a Log .rho. at 350.degree. C. greater than 7, an internal liquidus temperature below 850.degree. C., and a liquidus viscosity of at least 100,000 poises, said glass consisting essentially, expressed in terms of weight percent on the oxide basis, of:
