[EN] 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. [ES] Conocer las propiedades combustibles de las especies leñosas permite complementar el análisis e interpretación de las modalidades de adquisición y uso del material leñoso por parte de grupos del pasado. El método experimental permite profundizar en las propiedades que las distintas especies vegetales poseen como combustible, pero más importante aun posibilita la reconstrucción de los procesos que han generado el conjunto de restos recuperados. Este trabajo presenta dos objetivos. Por un lado determinar las cualidades que poseen como combustible cuatro especies leñosas (austrocedrus chilensis, fitzroya cupressoides, nothofagus antarctica y nothofagus dombeyi) y comprender su comportamiento en el proceso de combustión. Por otro lado, explorar si las ...
