Re: Very pretty, but do they work?
a few people like them but over all they are seen as crap. like was said glass has very low conductivity when it comes to heat (you can have one part at 2000*f and another a few inches away at 900*f so the heat will not get to all the tobacco evenly. also the shape seems to be part of the issue. the phunnel bowls that are glass seem to work better for most people.
i would stick with a mod bowl or other large egyptian bowl
