ABSTRACT:
During mount sealing, prior to sliding the mount assembly into the glass neck of a cathode-ray tube, the inner surface of the neck is coated with a film of volatilizable, organic material. Then, the mount assembly is slid into position and sealed in the neck. After sealing, the film is volatilized. Preferably, the film is thin, and the material is volatilizable when heated in air at temperatures below about 400.degree. C, so that it is easily removable by baking in the usual tube-making processes.
