Comparison of Drying Methods

Air Drying: Advantages

  • Air-drying is useful for small quantities of wet or damp materials.
  •  It is an attractive option because records do not need to leave the repository. 
  • It allows for item-by-item inspection and special handling.
  • Air-drying produced the best results with plastic coated materials.

Air-drying drawbacks

  • But air-drying also has several drawbacks. 
  • It is labor-intensive.  Time is needed to layout and re-assemble records, and to remove damp or wet papers from  plastic enclosures.
  • Air-drying requires large areas of surface space.
  • Cockling without restraint during drying results in increased volume of dried materials, and potential need for re-boxing or rebinding.
  • Coated papers will irreversibly block without interleaving.
  • Extensive handling of wet materials may cause damage.
