Gelatin hardening question

I've been having some sizing problems lately. Problems I never have in
months that are cold and dry. I harden gelatin with chrome alum and give it
a day to harden. Searching through the archives, I found a post where
Philippe Monnoyer mentions that chrome alum takes up to a month to
completely harden. Can someone elaborate on this? The degree of hardening
per unit of time is obviouslynot linear. What degree of hardening takes
place in 24 hours? How about in a week? Would glyoxal harden faster?
Lastly, is higher heat and humidity known to have a factor in the hardening
process?

Thanks.
