During my daily smoke I noticed my pipe got really hot! I mean almost too hot to handle. The only thing different about today is I smoked Escudo for the first time. I love this tobacco! Maybe I smoked it too much or too hard.. I'm sure that's what happened but one thing I noticed is at the top of the rim of my bowl the briar has turned a nasty black. No cracks though thank God but I'm wondering if I either packed my bowl too high and the combination of smoking it too hot may have done damage. God I hope not. It's my new Jacopo Picto15. Is it normal the the top of the rim get black? I hate to think I may have damaged my favorite pipe.
