We present preliminary results from the first phase of experiments from the Neanderthal Fire Technology Project, aimed at understanding Middle Palaeolithic combustion structures. Our field observations and micromorphological data address the sedimentary expression of various anthropogenic actions (trampling, ash sweeping and dumping, relighting and cooking) performed on simple, flat combustion structures made with Pinus nigra fuel on dry and slightly vegetated calcareous sandy substrates. We observed a characteristic pattern in microstructure and basic composition irrespective of the number and kind of anthropogenic actions performed. Trampling yielded previously documented diagnostic micromorphological features, more pronounced in cases of ash sweeping and dumping. Relighting of fires was only identified in cases with deposits between combustion events. Only rare microscopic calcined bone fragments and fat-derived char were identified in fires involving cooking or tossing of meat in the fire. These data suggest that: anthropogenic actions on simple combustion structures are highly undetectable; sweeping has a stronger effect than trampling on the substrate of the combustion structure; stacked hearths might involve significant amounts of time or deposits between combustion events; and alternative techniques must be sought to identify cooking in fires.

Hearths present sedimentary features, artifacts, and direct evidence for maintained and controlled fire in the past. The use of hearths reflects regular access to fire and its diverse benefits. Among these benefits are cooked food, protection from the cold and from predators, and fire’s transformative power regarding raw materials. Hearths may have also served as focal points of activity at Paleolithic campsites and triggered changes in social structures. As sedimentary features, combustion structures function as behavioral as well as paleoenvironmental archives. The papers in this special issue focus on the former aspect, how combustion feature can serve as transmitters of behavior, and with what tools we can explore them. We here briefly present an overview on the range of topics explored in these papers, which include ethnoarchaeological research on fire use among recent hunter-gatherer groups, spatial analysis of burnt lithics, actualistic experiments regarding fire function and...

Combustion features inform archaeologists about the prehistoric use of space, subsistence behaviors, and tempo of site visitation. Their study in the field is difficult because burned sediments are susceptible to reworking and diagenesis. Microarchaeological analyses, including micromorphology, are essential for documenting the composition, preservation, and function of hearths and other burned residues. These investigations focus on the description of fuels, depositional fabrics and structures, and mineralogy. As evidenced by a literature review, microarchaeological analyses have much to offer Paleolithic archaeologists, while applications of the techniques to Late Pleistocene and Early Holocene sites and in ethnographic or experimental contexts are presently rare.
As in traditional societies today ancient societies probably selected different fuels to meet specific heat requirements. Char and ash, the end products of fire, are often found in abundance in archaeological contexts. These end products can provide information regarding (i) the original fuel resource and type, (ii) the characteristics of the fire and (iii) combined with other archaeological evidence shed further light on possible socio-economic activity(-ies) associated with that fire. The three main fuel resources would have been (i) modern vegetation, (ii) fossil fuel and (iii) animal by-products. Local availability and abundance would have influenced the choice made.

Mallol C., Henry A. (2017). Ethnoarchaeology of Paleolithic Fire Methodological Considerations
Most of the ethnoarchaeological literature on hearths is scattered within general works that target many different aspects of foraging or hunter-gatherer societies. Although these works are a good source of ideas and clues for the interpretation of macroscopically observable features of Paleolithic hearths, there is hardly any high-resolution ethnoarchaeological reference material with which to compare microstratigraphic evidence of archaeological fire. Our ethnoarchaeological research at this scale has focused on exploring differential preservation of open-air hearths and the potential to identify fire-related activities and different variables of fire technology (fuel, temperature, and function) using micromorphological and anthracological analysis. Although these studies have been useful sources of analogy, further case studies as well as ethnoarchaeological examples of superposed and imbricated hearths and reference material from enclosed settings such as caves and rock shelters are strongly called for. In this paper we summarize and discuss aspects of our previous work to highlight the strengths and weaknesses of the ethnoarchaeological approach for the study of Paleolithic fire and propose possible avenues for future research on the topic.
Experimental Approaches to Archaeological Fire Features and Their Behavioral Relevance
The uses and functions of fire in early human adaptations are commonly debated and at times very controversial topics. It is important to recognize under what circumstances and conditions specific fire-related traces can be produced and preserved in the archaeological record. Currently, a growing body of data is emerging on the application of experimental research to the study of archaeological hearths and their residues. In this review, I draw together aspects of such available experimental data, particularly those pertaining to the sedimentary expression and components produced during simple campfires. I highlight not only what one can find in ideal preservation conditions but also what type of indirect alteration proxies can be expected to survive in the archaeological record. I then discuss the implications of such data for analyzing anthropic fire features, their timing, and their meaning in terms of behavioral complexity in the use and manufacture of fire during the Paleolithic.
Certain aspects of the formation processes of simple, flat archaeological combustion structures such as those present in the Middle Palaeolithic record remain unexplained. Such kind of combustion structures are commonly affected by postdepositional agents and often, their only distinct, well preserved component is a thin black lens on the ground. Hence, understanding the nature of this black lens is essential towards archaeological interpretation. From an interdisciplinary microstratigraphic approach, we present a case study in which for an entire experimental series of flat combustion structures the black layer represents the fire-altered topsoil on which the fire was made. Parallel analysis of archaeological Middle Palaeolithic combustion structures from the site of El Salt (Alicante, Spain) reveal similar patterns, leading to significant implications for archaeological interpretation. In the light of these results, special attention must be paid to the formation processes of flat Middle Palaeolithic combustion features, as black layers and the material contained in them are not necessarily linked with combustion but with preceding activities or events. In such cases, black layers represent intact remnants of occupation surfaces, concealing significant behavioural and palaeoenvironmental information relevant to the reconstruction of Middle Palaeolithic societies.
