Stones in the fire. Experimental studies on the spatial distribution of thermally altered lithics
In this paper we analyze the way in which lithic remains discarded in hearths are distributed. We perform experimentations in which we throw flakes of different sizes into the fire. Once extinguished, we analyzed the dispersal of the fragments generated by the fire. The raw materials are industrial...

We perform experimentations in which we throw flakes of different sizes into the fire. Once extinguished, we analyzed the dispersal of the fragments generated by the fire. The raw materials are industrial glass and siliceous varieties which come from the Central Plateau of Santa Cruz. Results show that each raw material responds to heat in a different way. However, there are also some tendencies related to the size of the artifacts. Small flakes don’t break much and stay within the hearth. Big flakes, on the other hand, usually break intensely and can expel a great amount of fragments outside the hearth, reaching more than 3 meters of distance. Based on these results, we make suggestions for different contexts in which lithics fall into the fire. En este trabajo, evaluamos el modo en que se distribuyen los restos líticos descartados en estructuras de combustión. Realizamos experimentaciones en las cuales arrojamos al fuego lascas de diversos tamaños. Una vez apagados los fogones, analizamos el modo en que quedaron dispersos los fragmentos generados. Las materias primas empleadas son variedades silíceas procedentes de la Meseta Central de Santa Cruz y vidrio industrial. Los resultados indican que las distintas materias primas responden de manera diversa al calor pero también que existen tendencias vinculadas al tamaño de los artefactos. Las piezas pequeñas tienen un bajo índice de fragmentación y tienden a mantenerse dentro de la estructura de combustión. Los elementos de mayor tamaño suelen fragmentarse intensamente y pueden despedir gran cantidad de partes fuera del fogón, llegando incluso a más de 3 metros de distancia. A partir de los resultados se proponen expectativas para distintos contextos de caída de piezas al fuego. Neste trabalho, avaliamos como os restos líticos descartados são distribuídos em estruturas de combustão. Realizamos experimentos em que jogamos flocos de vários tamanhos no fogo. Após a extinção dos fogões, analisamos a maneira como os fragmentos gerados foram espalhados. As matérias-primas utilizadas são variedades siliciosas do platô central de Santa Cruz e vidro industrial. Os resultados indicam que diferentes matérias-primas respondem diferentemente ao calor, mas também que existem tendências relacionadas ao tamanho dos artefatos. Peças pequenas têm um baixo índice de fragmentação e tendem a permanecer dentro da estrutura de combustão. Os elementos maiores tendem a fragmentar-se intensamente e podem descarregar um grande número de peças fora do fogão, chegando a atingir mais de 3 metros de distância. A partir dos resultados, são propostas expectativas para diferentes contextos de peças que caem no fogo. Facultad de Filosofía y Humanidades.
