I've got an old CRT that is decaying along the glass edges.
I've seen foam turn to dust, rubber turn to goo, batteries turn to acid,
but I hadn't expected CRT glass to revert to sand. Sam tells me that he's
seen something similar on his Soroc terminal.
What process is causing this? Isn't glass basically SiO2? I assume it's
crystalizing rather than oxidizing.
Anything I can do to prevent it from occurring on other tubes?
Any interesting risks associated with firing an electron gun at this
crystalized stuff with no remaining phosphor?
