The Conservation State of a Wooden Archaeological Fragment Influenced by its Physical Properties. Treatment Proposals

Summary/Abstract: The conservation state of archaeological wood can be defined by its preservation conditions: either in dry medium, either the wood preserved underwater that has developed stability in this medium. The evaluation of the conservation state of the archaeological wood saturated with water was based on results from measuring the maximum humidity content, mass density, loss of wooden mass and the maximum contraction index of the analysed samples. After comparing the values obtained for the five samples it was established to which degree the archaeological wood is affected by the raise of humidity content in relation to the mass density value. The archaeological wood contraction is higher than the raw wood’s and it can reach values that justify the deforming, the cracking or even the breakage of the object. Thus, the drying of the objects that have been lingering under water becomes the main issue in the conservation of archaeological wooden objects.
