I have searched the forums, and could not find exactly what I was looking for… When I smoke my pipe, it feels like a hotspot develops randomly on the outside of the bowl. It is never in the same spot, and only lasts for a minute or two. I generally smoke very slowly (thanks to all the postings and YTPC videos on “sipping”) , and as soon as I feel one of those spots develop, I take a break until it is the same temp as the rest of the bowl. The whole bowl stays relatively cool, so how concerned should I be about these hotspots? I definitely do not want to damage any of my pipes, and the insides of all my bowls show no signs of burnout. Thanks!
