Abstract
A method for fabricating a CRT (cathode-ray tube) in which a partially-completed faceplate-panel assembly is baked-out and heat-sealed to a funnel during the same baking cycle. Jets of oxygen-containing gas are directed intermittently into the open neck of the funnel at least during the heating-up period of the heating cycle.
