[CAUT] Query about "Cold Storage"

[Ron Lindquist]

A old timer, who was a good chemist told me  that   the change in 
concentration of   elements  was what caused 
problems.    Moisture  ,   when it changes    states ,  causes all kinds of 
problems ---that is,    in regard to  wood , pianos ,---Temperature 
,  (    3/3.   Who was  Ospensky  (sp))
I've  had  four  pianos, --  go  from  + 93 % R.H. at,  98  Deg. F. 
,   to   -----,  minus 45Deg.-F---almost   5% R.,H.
Change temperatures slowly    to     let  moisture   aqulimate.
