Building a fire involves many variables, such as size, choice of fuel, temperature, and burn time, that affect the way the generated heat can be used, and therefore the potential function of a fire. A group of Leiden archeologists are, together with a team of international colleagues, investigating remains of Paleolithic hearths in order to characterize the use of fire by our distant ancestors. Results of this project, initiated by the late Freek Braadbaart, were recently published in the Journal of Archeological Science. We spoke with one of the authors, ancient fire expert Femke Reidsma.
