Re: Cool your smoke?
I normally don't add ice, mostly becasue either it won't fit or the trays are empty (BF is a pain @ refilling them).
BUT... since I have 2 of the same vase, I keep one in the fridge 24/7 and a container of water with it. That way, I'll have a chilled set-up anytime I want (or ateast ice cold water). Seems to work great and the chilled base does seem to stay colder longer than just filling it with ice.
Don't try this trick with THIN WALLED BASE JARS! It will Crack them due to thermal differences! Thick Egyptian jars, heavier bohemian, and the lot are the best.
