ABSTRACT:
A method for fabricating a glass CRT panel that exhibits high compressive surface stress and low compaction comprising thermally processing the panel during the initial annealing stage for a prescribed period of time at about those temperatures that produce minimum compaction, which processing temperatures are substantially lower than the processing temperatures that produce minimum surface stresses in the panel, and then cooling the panel to room temperature.
