that's good to know then.
when i did spill some, it just froze up and made much more ice around the pot. so i got one of those little mini funnels to pour in.
but yeah, i dont use much at all. just enough to cover the bottom (like about 1/4" or so). then of course the pot is near a window and the fans on the board seem to take care of any lingering smell or fumes.
