I just started smoking in late July, early August and I'm having an issue with my pipe getting really hot. At first I thought it was because I was having to re-lite the tobacco a lot but I'm down to a two match lite and no re-lite and it still gets hot. Is this normal? I don't think I'm smoking excessively fast, about 20-30 minutes a bowl. I do smoke mainly aromatics, specifically a blend of black Cavendish and vanilla Cavendish from my local tobacconist.
