A customer asked me why the original ivory heads on his 1925 Steinway M were
beginning to crack up the center. I told him I thought the wood in the keys
and the ivory on top were expanding and contracting at different rates when
the relative humidity changed. Because they were glued together something had
to give and it was the ivory.
My question is, was my assumption correct and if so would a humidity control
system slow the cracking process?
