At just over 11 inches tall the Blaze Glass 'Mushroom' might not be big, but it is clever! The removable downstem has a diffuser at it's base to break up the smoke and make the water's job of filtering and cooling a little easier. Then the smoke has to rise through the 'Mushroom' which is actually a cleverly designed splash guard designed to stop water from making it up the short distance to your mouth. Just above the mushroom are a trio of ice pinches which give you the chance to add a couple of ice cubes for that glacier chill. The downstem has a 14.4mm female ground glass joint and Blaze include a 14.4mm male bowl to fit.
