How to save cracked glass?

On my bong, the stem is cracked where the bowl slides in. It's slowly getting worse. Does anyone have any ideas for saving this piece?

It's probably been jammed in there a bit harsh once or twice. I can only recommend a bead of araldite along the cracking area.

The only way to fix this is to have it fully re-heated and a new joint put on; otherwise you're just slowly waiting for the inevitable to happen.

I don't know how well this will work but you might want to look into sugru. I use that shit to fix everything.

JB Weld. My stem cracked like that. I mixed up some JB Weld 2 part and coated it. Just tape of the rest of the piece so it doesn't get everywhere. If you take your time, it won't look to bad. Just a shiney black band around the stem. Quickstelp would also work, don't think it would look as good.
