If the substance bonding the front glass to the the CRT is some sort of RTV
silicone compound, you might be able to remove it with silicone sealant
remover.  I don't know exactly what's in that stuff, but plumbers use it to
remove old silicone sealant from shower panels, tiles, and fittings.  You
might be able to get it from a plumbers' supplier.
