dThe main objective of the research is to deepen our knowledge of how Iron Age combustion structures worked and were used by protohistoric communities living in the western Mediterranean. Six hearths and one oven, made with mud and other materials, such as crushed pottery and pebbles, were built inside buildings and outdoors. Later, they were put to use employing diverse types of fuels, while measuring time and temperatures reached under different conditions. Diverse analyses are being applied to samples taken from the experimental combustion structures.
