The properties of woody fuels during the combustion can complement the interpretation of the modes of acquisition and use of firewood by groups of the past. The experimental method allows to deepen about the properties of different plant species as fuel, but more importantly allows the reconstruction of the processes that have generated the archaeobotanical remains recovered. This paper has two objectives. For one determine the combustion properties of four woody species (Austrocedrus, Fitzroya cupressoides, Nothofagus and Nothofagus antarctica dombeyi) and understand their behavior in the combustion process. Furthermore, explore whether shrinkage cracks present in the charcoal respond to water content the firewood (green-dry). The performance of 16 experimental combustions and the study of the charcoal produced during combustion show differences between woody species studied. The results allow, in some cases, to discriminate the use of dry wood and green wood as fuel. The results obtained allow on one hand, discriminate the use of dry wood and green wood as fuel. On the other, deepen the identification and interpretation of the alterations present in the archaeological charcoals and complement the archaeobotanical analysis of the different sites Patagonia.
