Abstract: A cathode-ray tube including, on its viewing surface, a glarereducing coating composed of a lithium silicate material and carbon particles. The novel method comprises: (a) warming the surface of a glass support to about 30* to 100*C, (b) coating the warm surface with an aqueous solution containing about 1 to 10 weight percent of a lithium-stabilized silica sol and a sufficient proportion of carbon particles to produce the desired reduction in light transmission, (c) drying the coating, and then (d) heating the dry coating at about 150*C to 300*C.
