I don't like the idea, the stink, the insecurity of the glass flopping over at 2 am when it fails, etc... I'm not sure what the breakage problem is ( silicon won't help that unless your strictly speaking about braking glass upon install and that's never done twice after you learned your lesson the first time).
(I've listed some tips for this in previous crane threads) ... Please only lightly snug all screws evenly, do not tighten one all the way then next one all the way, etc.... Again, your just holing the ceramic glass in place (NOT squeezing it down).... If your placing to pressure on the glass even if you don't brake it upon install, you will inevitably cause the brake when you slam the door inadvertently.
I've heard of furnace cement used on some applications of glass/mica/ etc. but even with that their is always a bracket as well.
