My CRT is coming along
After a few weeks of soaking, I've removed most of the broken faceplate, save for a few pieces.
I took a pealed off piece and experimented. Acetone tends to soften the stuff pretty well. I soaked the remainder of the tube in acetone and this netted the softening of the bonding agent. A putty knife could dig out, and even better, dig between the agent and the glass, breaking the seal. I removed a few large pieces, leaving one piece (which doesn't want to be a team player), stuck to the glass. it's soaking now, and hopefully by tomorrow afternoon it'll have absorbed some acetone and softened to the point where I can get a putty knife in to break the seal and peel it off. Once it's gone, I'll wipe the tube and put it into my Zenith, where it belongs....
