The old sets with flat plates of glass are tinted and tempered.
They were pretty strong and thick. I would throw some in a dumpster, they would not break unless smacked hard with a hammer.
The glass bonded to old tubes with resin are thin, crack easily, most are treated on the outside to be dull looking, not shine, most were tinted dark.
The next version used glass that was not tinted, designed to reduce x-ray exposure, and let more brightness through, mostly used on black matrix tubes.
