The other night, in a fit of laziness, I decided to see how long I could keep the pipe going without having to reach for the lighter. Rather than fannying about with all sorts of techniques, I just used slow rhythmic puffing with an occasional tamp. And lo and behold the damned thing kept burning for a little over 1 hour and 40 minutes! I believe this is a pretty respectable time even for those slow smoking contests. It was also a very relaxing experience and put me in a good mood. Some would find it boring, but it's ideal for creating the time and space to sort things out in your mind. My life is more complicated than it needs to be, so this kind of activity is both useful and refreshing. If any of you know about slow smoking techniques, please post. All I did was to synchronize puffing with breathing: after every 2 breaths I puffed, and then after the next 2 breaths I blew lightly into the stem followed by a puff. It was definitely burning faster than it needed to, but I didn't worry too much about that. The smoke remained nice a cool. And the pipe never got hot either. For reference I used a Savinelli 315 EX filled with about 3 gm of Mac Baren Va. No. 1. After 1:40 there was still enough tobacco left for another 30-45 minutes of smoking.
