damn that's a shame! I've seen way too many pieces go in similar ways, which is why I came up with Das Boot!....

how exactly did it happen?

to answer your question about using JB Weld, I've personally smoked out of pieces that were "fixed" using "food safe & heat resistant" silicone, but it seemed like the lack of air flow on the inside of the pipe never really allowed the toxic smell to go away...

Perhaps you could try running something like a fish tank air pump through the female stem of the pipe for a couple days to make sure everything dries out and all the smell is gone.... but I'd personally just chalk this one up as a loss, and switch back to dry pipes or papers until you can afford another one... And on the next one you get, you can always protect it with something like a Das Boot!
ThePipeSaver Reviewed by ThePipeSaver on . A Bong Fix. I had a bong that was shattered by an ashtray and glued it together with J-B Weld it is water proof and i hear its drinking water safe... it takes 24 hours to dry, doesn't expand, you can break glass before the "weld" will break and it looks somewhat clean. if you can fit the glass together it wont even look that bad.(i think it would look better if i got another try) Heres some pictures Missing Glass Hole Patch Missing Glass Hole Patch 2 Best looking patch Best looking patch 2 Rating: 5
