I am not so sure. I don't think that 2 sheets of

safe as laminated glass for a car windscreen, for example. I don't know
if the outer faceplate is enoguh to stop the fragments of CRT, and I do
not intend to find out by experiment. I do feel that the adhesive
between the 2 layers does help to keep the bits together if the CRT
implodes, though.
I'm sure that it's certainly not a shatter guard. However, if you
looked at US televisions made before about 1956, you'd see that the
plain faceplate CRT had a sheet of plate glass installed in front of it.
Some of these got as large as 21", but my family had a 7" 1950 Philco
that had that sheet of glass also.
