Clay hookah bowls are becoming increasingly popular for a number of reasons. For one, clay is a natural material that is non-toxic and won't affect the flavor of your tobacco. Additionally, clay hookah bowls help to keep the tobacco moist and flavorful, and they're also easy to clean. One downside of clay hookah bowls is that they can be fragile and may crack if dropped. However, overall, they offer a number of benefits that make them a great choice for hookah smokers who are looking for a high-quality smoking experience.
