Bump! 8O Long post...
I tried this today, as per Mr. Pease's original article, and here's what's happened so far. I just removed them from the oven now. I tried it on three pipes, each with a different history- an old Medico, an estate Shamrock, and my Big Ben. All had recently been given just one S/A treatment that didn't do the job, so rather than do a second S/A, I earmarked them for the oven. They are all going to sit for a day before I put the stems back on.
First the cheapie Medico. This pipe was exclusively Captain Black Royal and White for a few years when I was first starting out. I haven't smoked it in a long time, but the aroma was still there even after cleaning. First sniff after removing from the oven? Nada. Zip. The smell is completely gone. I'll call it a success for now, but I'll have to fire it up with a completely different blend than CB just to make sure.
Second, the Big Ben Presidential. I ordered this pipe years ago from Frenchy, and it was one of my first really good smokers. As such I ran a whole can, that's a whole can of Argosy Black when it was on the market. The stuff smelled amazing, and the pipe has never shaken it since. I actually liked the smell, but since it was my most persistent ghost I gave it the treatment. There is still a sweetish smell, but most of the Argosy is gone. I'll pass judgement on it when I smoke it again but I suspect a second treatment, S/A or oven, would possibly be the one that kills it once and for all.
Lastly, the Shamrock. I don't know exactly what was smoked in this pipe by its previous owner but it's really hanging on in there. Caveat- I smoked it once after cleaning and S/A, and it still had the original ghost taste to it. So it went into the oven with the first ghost and one bowl of Lord Methley courtesy of me. Verdict, aroma is still present so it needs another treatment for sure. I don't think my one bowl made a difference given the smell, but it will still take some work.
Anyways, to sum up...this is a very easy process to follow overall. I'll probably try it again soon on some other estates, maybe for an extra hour or two (?) and I'll post any neat findings here. I don't know if it's the be all end all yet, but it's definitely worth a try.
