The best thing to do for small diameter gauge glass is to seal the ends
by partial melting with a small propane torch. This doesn't have much
anything to do with operating temeratures/stresses, etc, but seals the
fractured ends and considerably reduces further fractures. It takes a
little practice but once you get the hang of it it's very quick and easy to
do.
