I was cleaning my favorite glass pipe today; It's my first piece ever, I've had it for over 5 years, and it's traveled across the country with me many times - needless to say, it means a lot to me. While cleaning it over my, ceramic, sink, it slipped out of my hands and the mouth piece hit the sink bowl and two exterior pieces chipped off. The overall shape of the bowl is totally untouched,and it's definitely smokable without the chipped pieces but the mouth piece is jagged now - not something I think is very safe to put my mouth on or very aesthetically pleasing. Now, I know glue and heat doesn't really mix, but these chipped pieces are as far from the bowl as possible and will never touch the flame. Do you guys think it's safe for me to just glue the two chipped pieces back on? I already fixed them into place with a few dabs of Elmer's which is holding very well - I want to make sure it's not unsafe to smoke from though.
