Re: want to buy a pyrex bowl. "any thoughts?"
I had the original "Smiley" pyrex bowl that came with the pyrex glass screen.
It was the only bowl I smoked for about a month, because of the amazing design- the air holes were more to the side of the inner bowl, not the bottom, so air flow was excellent. The glass screen also fit perfectly. It smoked like a dream.
Then one day I had been smoking for about an hour, *barely* touched the glass with my tongs, and the whole thing shattered.
I bought another Pyrex bowl of a totally different design and brand. Third session- same thing.
While Pyrex doesn't conduct heat as easily as regular glass, it also seems to make the material much more fragile. Just FYI.
