But at that time (before Frit was developed) what other options did the CRT manufacturer have for joining the funnel to the panel? Metal tube, welded like the prototypes? other sealing methods?
I have never been able to determine the seal method used on my Westinghouse 22EP22. There is no visible frit bead (frit as we know it today had not yet been developed), and only a faint line can be seen where the funnel and panel join. Solder glass perhaps? Flame seal? Early experimental frit like substance from Corning?
