cossackjack: Oh, sorry about posting to this thread - I thought it would be appropriate, being as it was a similar-sounding problem.
Yeah, I think I *have* been (puffing too hard/fast). The rim charring is probably due to my inept use of a Bic lighter to try lighting up. I got the idea that if I put a long pipe cleaner inside the stem while I'm smoking, it would act to catch some of the tar and moisture from the tobacco, but it also makes the draw too weak, which allows the flame to wander to the rim instead of getting properly sucked down into the bowl. I'll stop doing that from now on.
Any thoughts about using clay to repair the fissures? I haven't found any instances via web searches where this was tried.
kirkland: Not sure who "Brebbia" is. This is a "Lord of the Rings" Dark Wizard model pipe I bought from Danny Boy Pipes - the manufacturer is Macqueen Pipes.
balkisobrains: Yes, I think that's the consensus here (I smoked this pipe too hot). I am a newbie, and am dealing with all kinds of problems (tongue bite, charred rim and bowl, cheap tobacco, bad ideas/practices). Who knew pipe smoking was quite so complicated? Any thoughts about using clay to repair the bowl's heat fissures? Or should I just stick with pipe mud? I spoke to the proprietor at The Piedmont Tobacconist, and she mentioned a recipe of ash, sugar and water for pipe mud.
theloniousmonkfish: The Dark Wizard pipe is cherrywood.
