I know the down stem and bowl are reparable, but you know the piece that you put the down stem inside of? i cracked it and a piece fell off, is it possible to fix that part of the bong since it doesnt come off ?
Yeah that's a pretty common repair for the glass blowers that do repairs.. Just needs a new ground joint I assume.
Glass blowers direct will fix it. Not sure your price range though http://glassblowersdirect.com/repairs/
