Kurt, Thanks for the experience..You have an admirable talent and a great willingness to help and share with others.A gift!
One cannot help but wonder what the 'water' may have been like used to boil that poor batch from which your experience came.
Boiling water is..well ...pretty constant in temperature..

so it may have been the duration of the boil?
Polluted water which left acidic or alkaline or mineral ( or worse) residue in the briar wood?
Cook brocoli or snap peas in polluted water, drain and eat them..the water does make a difference as some of it, with whatever impurities it contains, is absorbed..detectable even after dehydration or drying to 7% MC.
Tainting after the processing by air, sun, mold or whatever?
Hard to know I suppose.
Anyhow, I'm not presently planning on boiling any of the briar from the one burl I have left when I saw it further into ebauchons or plateaus for the next pipes.
Not even with distilled water..
The briar is so nicely seasoned and the initial pipe I made came out so well that I haven't the heart to subject the wood to it.
FWIW, the first pipe I made from the burl smokes very nicely, cool and smooth and even the finest fitment of stem to shank and measurements of bowl diameter haven't changed an iota since breaking in .Not a fill or a flaw nor crack or check..Perhaps I was just lucky..It has a simple oil finish only..polished by hand and waxed.
While I admire the pipemaking heritage, the families ( and entire towns )who have made wonderful pipes and produced stummels for many others over the years..at times I wonder IF some of the trade secrets and guild-like processes they have used over the years to differentiate theiir work from others may be a good part advertising hype designed to cloud good pipemaking with a mystical aura of sorts..from how truly simple it is..while having the potential for being a profound craft and art.
From the 50 year or older heather shrub in the rocks to the charm light over well packed good tobacco ..they do their best to make and sell their work and establish a reputation....so their work is more highly sought after and paid for.
Does the $1500.00 pipe made by a renowned house or artist smoke better than the 20.00 one?
Perhaps...but it is human nature to value those items one spends more for even when a simpler less expensive item would do as well...and few would boast to his fellows that their least expensive pipe was their go to smoker when they had such a pipe in the rack.
.
It would be an interesting experiment among descriminating pipe smokers to smoke many pipes of similar style without knowing who made them, when, or where...blindfolded, perhaps touching just the shank of the pipe...all with the smokers same. chosen tobacco.
A James Cooke? Edwards? Grabow? Mark Tinksley?
Over the years I have enjoyed smoking many fine pipes..Usually the time, place..perhaps the people present.. and setting ..with the good tobacco made the pipesmoke respite memorable and enjoyable...and I have had such smokes many hundreds of times with 6.00 pipes or 600.00 ones...from corncob pipes, clays, meerschaums, porcelains and many briars.I love them all..
For me, pipes are made to be smoked and enjoyed..With the making of one's own, there is an added dimension to that pleasure.
I am sometimes amazed at the highest dollar pipes, exquisitely done which pass on at auction or estate sale and have hardly if ever been smoked.
Of course I also see vintage firearms of the highest quality..designed for hunting, which have scarce been fired..let alone taken afield..Go figger..
Sorry for the rambling.I'm getting old and it's late..Jim
