I disagree here:

"Finally, it should be noted that the effects of the tempering or the heat strengthening process can be reversed by re-annealing (stress relieving) the glass. "


Anyway, I just hope Howard says that Harrelson said that Shapton will be making them narrower! Before I try anything though, I'd call Shapton and ask for details about the specific glass used and how the ceramic is held to it in hopes of finding how to un-do it.
