The float glass flat faceplate does not require polishing and acid etching to provide a high degree of smoothness in its inner and outer surfaces and, in combination with a flat tensioned shadow mask mounted to the flat faceplate, offers a low cost, easily manufactured and assembled color CRT front assembly.
