Here are a few other angles, there is a lot going on in this small piece (about 4+ inches long).
The piece is at a glance just a bad-ass fully worked chillum, with two opals and a dichroic filled marble. The clear chamber is typically what confuses people because one expects the hole to be a carb, but the clear area is simply an alcohol chamber completely independent from the vapor path. Fill it with alcohol, plug the hole with a pencil eraser, load the bowl, and toss it in the freezer.
I haven't used it in years, but best results were if packed before freezing. The less you handle it when it gets out of the freezer, the better. The whole piece frosts up when you pull it out
The end result is a super smooth pull, almost don't notice anything but flavor on the inhale, not icy cold but very cool.
Bought in the midwest, around 2002-2004.
