Air Drying Procedures:
- Collection items in this category should be handled by staff (or a conservator) trained in the recovery of these materials.
- Use controlled drying methods for parchment and vellum to avoid severe distortions and shrinkage.
- If inks are insoluble, lightly blot items with absorbent material.
- Dry materials between non-absorbent sheets or sandwiched between blotters, with a light-to-moderate weight board on top.
