[NHCOLL-L:1727] Acidity

[Heidi Fourie]

Dear everyone,

We have a problem with an acid level of 2.0 in one of our strong rooms.  It has humidity readings of between 40-44%.  Several collections are stored in there.  Mainly archival documents from the finance department dating back to the early 1900's, an alcohol herpetology collection, a mummy, a very valuable painting collection, some guns and odds and ends.
When discovering the low acidity we moved the alcohol collection out.  My main question:  What about the paintings (all original drawings with pen) and the dehydrated (sun dried) mummy in a glass case.  Should we seperate these collections all together?
Any advice will be appreciated, either privately Fourie.h at nfi.co.za or to the list.
