ok here is the thing i broke my glass bowl for my bong and i fixed it with super glue but im afraid to use it because i dont know if any got in the bowl now if i burn out the bowl will it be safe or can i just load it and go.
Do NOT use Superglue on any area exposed to smoke, not a very good idea. Only time I would ever use Superglue on glass is if a marble or other decoration on a piece broke off.
Don't use it. Heated superglue releases toxic vapors. The only way to repair glass is to weld it back together with a torch. Either that, or buy a new bowl...
