Within the bi-national research project CuTAWAY (Conservation and Wood Analyses), which was funded by the German Research Foundation (DFG) and the Swiss National Science Foundation (SNF), further analyses on wet wood conservation could be carried out together with the Lucerne University of Applied Sciences and Arts (HSLU): A selection of 83 samples from the already established reference collection was evaluated using different investigation methods, such as computed tomography (CT) or scanning electron microscope (SEM), focusing on (i) verification of the results of the different conservation methods, (ii) the mode of action of the conservation agents, and (iii) the effect of the conservation methods on the wood structure (non-destructive dendrochronology using CT). In addition, another series of experiments documented the structure of the samples before and after conservation and during variable humidity by CT.
