Re: When am I done?
It really comes down to when you feel like you are done. In my experience most bowls can handle 2 rounds of coals, more for phunnels and vortex bowls. If it is a wetter tobacco i can get 3 solid hours out of my vortex if i really want. There is no law stipulating you have to finish off every single iota of tobacco.
Generally, unless i am REALLY digging the flavor and stuff, i just stop after one round of CH coals.
