The universal question that pipe smokers the world over ask is when do I ash? Ash you ask, what is it too ash? When your pipe goes out instead of trying to relight the bowl through a pile of ash, you gently stir the ash. Then you tip the bowl and dump said ash into your ashtray. You then tamp your tobacco and then relight. I might have to ash 2-4 times a bowl it all depends if I am paying attention or not. I never think about trying to smoke my pipe to the bottom on one light. I hardly ever do it as I am usually typing or reading and my pipe goes out because I forget to puff.
Now that you understand the principle of ashing, ask yourself how have you lived this long, not knowing when to ash.
