I am doing research on the ways museums control relative humidity in
object cases, in larger diorama size cases and in the galleries
themselves. Specifically, I have come across some research from the
early 1990s looking at using different kinds of chemical compounds
(in crystalline form) instead of silica gel. I am wondering whether
anyone regularly uses compounds other than silica to control
relative humidity?  Any help would be appreciated,
