Re: coal and shisha questions
1. shisha is done when there is no flavor/smoke has a burnt flavor which means you pretty much burnt the shisha more than you should have.
2. after a session i usually let the bowl cool down then clean it out throwing the foil and shisha away
3. number of coals depends on the size of the bowl. a small bowl can use 2. a bigger bowl such as a phunnel bowl and use 3 at a time. if using a small bowl you can experiment with the amount of heat that can go on it before the smoke will become harsh
