Subject: Coating on drafting linen
The Field Records Library collection includes many maps, charts, etc. drawn or copied onto a linen-base material, which has a smooth surface. Many of these items have an odor, even though the material does not appear moldy, discolored, etc. It is not a musty/dusty/moldy smell. It's more of a sharp smell. A Colleague has suggested that the linen was treated with a paraffin based product of some kind, and that the smell may come from the deterioration of that product. Anyone out there have experience with linen-base material like this, and or know the source of this smell? With many thanks.
