Archaeological wood - its properties and research potential
Abstract
We studied basic physical and chemical properties of archaeological wood buried in the soil or preserved underwater in the Ljubljana Moor, Slovenia. The wood of oak (Quercus sp.), ash (Fraxinus sp.), alder (Alnus glutinosa), beech (Fagus sylvatica), and maple (Acer sp.) was selected from vertical piles from 5 prehistoric pile dwellings from the 3rd and from the 4th millennium BC. Moisture content above 500% and a drastic decrease in basic density indicated a very high degree of wood deterioration. Shrinkage was much higher than that in recent wood. Chemical analyses of ash-wood have shown a drastically increased amount of lignin and a reduced amount of cellulose and hemicelluloses. The results present basic knowledge for future planning of proper conservation treatment.
