Just a guess here, but most faceplates on metal CRTs were quite thin, because they were strengthened by being placed in very strong compression as the metal to glass seal cooled. I suspect that the glass is not much more than 1/4-3/8" thick.
Update: I just crawled into my attic and weighed a 22" metal cone DuMont radar tube (P-7 phosphor) and it was only 33 pounds. a 16AP4 metal cone CRT is only about 11-12 pounds.
