Waterlogged wood samples from 1-2 typical archaeological sites will be selected, then sampling, analysis, desalination, de-ironing (or preliminary metals removal), consolidation and dehydration experiments will be carried out in both laboratories, and characterisation protocols will be drafted, including:
1. Samples will be analyzed anatomically, physically and chemically previous to any treatment. Samples will be dated through dendrochronology and C14 methods. Decay characters of wood samples from Italy and China will be compared and diagnostic protocol will be drafted.
2. Analysis of the inorganic deposits in wood samples will be analyzed and removed. A pre-standard for desalination/deironing will be drafted, and the characteristics of woods evaluated again and compared with those preliminary to treatments for inorganic deposits. The most successful protocols will be used for amending the Italian National standard UNI 11206:2007.
3. Samples consolidation with common protocol in both laboratories and dehydrated; the various treated samples will be analysed to assess the conservation efficacy (scanning before and after treatment to assess the shape and volume variations, observing at SEM, chemical analyses aimed at assessing the state of preservation and emissions, creep-related aspects after treatments etc.); then a protocol for consolidation and dehydration will be drafted.
Amending of existing standard, formulating pre-standard and publishing scientific papers.
