Abstract
PURPOSE: To slowly cool a glass article having a convex surface without forming rust, a crack or a contact mark on the edge and inducing heat deformation by mounting the article on a flat stand with the convex surface downward followed by slow cooling.
CONSTITUTION: A glass article having convex surface 11, e.g. panel 10 for a TV cathode-ray tube is mounted on flat stand 14 with surface 11 downward and slowly cooled while being conveyed through a slow cooling furnace with endless conveyor 13. Stand 14 has a flat surface and is pref. made of stainless steel, asbestos, alumina or the like which is not damaged and withstands the slow cooling temp.
