Kiln dried vs Natural seasoning

[Farrell]

I'm quite sure you'all are speaking of two different things. When
Bosendorfer or whoever is referring to kiln-dried wood, they are talking
about how the wood they use got from being a living tree (saturated with
water) to a dry state - in equilibrium with its surrounding atmosphere
(relative to its moisture content). Whether a manufacturer then goes another
step and takes their "seasoned" or dried wood and dries it a bit further for
purposes of building a soundboard is unrelated to whether the wood is air
dried or kiln dried. The air or kiln drying refers to getting the wood from
the saturated living state to a dry state that is in equilibrium with normal
atmospheric conditions - not whether they dry it a tad as part of the
soundboard building process.

(I'm sure Ron or Del will correct me if I boo-booed here.)
