The difference between a Syrian and an Egyptian shisha bowl is that the hookah tube goes inside the base of the bowl while on a Syrian bowl the base of the bowl goes inside the shisha pipe stem
1. Pros and Cons
+ Low cost. Widely available and cheap clay bowl
– Ash contamination. Ashes pass trough the foil and get into the shisha
– Possible burning of the tobacco. Still possible burn the tobacco if it is overheated
– Breaking. Clay and Pyrex bowls can break.
– The tobacco heats unevenly and from time to time the tobacco overheats (burns) giving a bitter tasteless smoke
