Hookah Bowl
From A Wiki in the Desert
A Hookah Bowl is a fine glass basin used in the construction of a Hookah. The hookah bowl is shaped in a Glory Hole from a Fine Glass Rod. Like other items crafted at a Glory Hole, each hookah bowl has an individual quality rating (from 1 to 9999); the quality governs how many puffs may be taken from herbs in the hookah.
