Re: Where can I find a Pyrex vortex bowl?
while they arent vortex bowls CrownHookahs glass bowls are pretty amazing. I lucked out getting a micro funnel bowl from them and it has given me excellent sessions and the tobacco is cooked so thoroughly. Maybe you could check them out to see if they are to your liking.
You could also PM CrownHookahs, Santino does custom work too.
