Silica Gel Information requested.
I would like to hear from anyone who has worked with silica gel as a
buffering agent for sealed exhibit cases. More specifically, I would like
to know what ratio of silica gel-to- case volume has proven effective in
maintaining a reasonable RH range over time (say, three months).
The Canadian Conservation Institute recommends 20kg/meter cubed (a lot!).
I have cases with volumes ranging from 25 to 75 square feet, so I would
like to know if we can use less than this CCI recommendation, but still
buffer the RH effectively. Any ideas?
I am not a member of this list, (Jan Turner is our Institutonal member).
