A method for forming identifying indicia (20) on a cathode ray tube (1) applies a paint (P) containing a powdered metal to a particular exterior surface portion of a glass envelope, forming a part of the cathode ray tube (1), to form a solid paint layer. Then at least a part of the solid paint layer (Pa) is irradiated with a laser beam (L) to form the identifying indicia (20) represented by at least one trace of plasticized deformation on a surface region of the solid paint layer.
