its a double with both downstems perc'd. that middle tube is a snorkel so the bottom of the piece clears out. it was 70 at a local shop(ghost dog); the glass isn't too thick but the welds are nice. i dont see alot of bubs break anywhere but the welds, naw mean?
Nothing wrong with thin glass. As long as it was made well and ya take care of it, last a life time! Id hit it for sure. Doubles are always smooth with cold water.
the snorkel tube is an extension of the carb so it goes down near the water instead of closer to the bowl. it makes it so theres no stale smoke, and yea i love glass. im thinking about buying a torch, im going to take some classes..
i like this piece a lot. I enjoy clear pieces because you can see them filling up with smoke an all.. Nice post OP!
