interesting wood article

Another interesting point seems to be that aged wood having possible positive
benifits in music instrument making perhaps is not so unreasonable a proposition
after all.  As wood gets older, according to proponents of this school, it
becomes stiffer, lighter, looses some of its hygrophility (ie becomes
significantly more stable in the face of changes in humidity), and displays
lower EMC levels. One of the down sides is that it becomes more brittle.
Evidently the velocity of sound through wood increases with these changes... ie
aged wood will conduct sound at greater speeds then new wood.  These seem to be
the same kinds of characteristic changes embraced by a few companies around the
world using new technology thermo treated wood in music instruments. They are
able to register increased sustain qualities in instruments when compared to
controll instruments made of untreated woods... or so they say.

Who knows... :)
