    Wood is petrified through a process of mineral replacement. Once =
petrified, the object that was once wood becomes rock. Petrification =
occurs over a very long period of time - thousands/millions of years. It =
can occur when wood is buried in the ground and groundwater migrates =
through it - it is the groundwater carrying dissolved minerals that is =
the vehicle for wood petrification.

    Wood does not become petrified in a functioning, non-buried piano. =
Period.

  You're right about wood but -- based purely on experience -- perhaps =
not when it comes to wool. Some hammer makers have figured out how to =
shortcut the process in their hammer presses.
