Wet Organic Archaeological Materials Working Group
Triennial Programme 2017-2020

Working Group Activities and Projects 2017-2020


Specific themes for investigation/research

  • The ethics and practicalities of treating waterlogged materials, especially large structures or large assemblages.
  • In situ preservation of waterlogged organics.
  • New treatment techniques and continued review of older techniques, such as Kauramin, PEG, Sugars, Alum etc. In particular, we welcome studies that address the long-term performance and stability of treatments, especially those that reassess the condition of the materials treated as part of the International Comparative Wood Study and currently stored in Trondheim.
  • The treatment of composite materials.
  • The treatment of non-wood organics.
  • The display and storage of waterlogged (and previously waterlogged) organics.
  • The role of sulphur and other contaminants in the deterioration of wood and other organics and ways to mitigate these effects.
  • The documentation and characterization techniques for recording and assessing waterlogged organics.
