Vitrification and craft fire in occidental Mediterranean
Résumé
After analyzing several sets of charcoals sampled from various archaeological and ethnological contexts in western Mediterranean, a scale to evaluate the vitrification phenomenon has been elaborated and applied to archaeological and ethnoarchaeological charred material. Thus, it reveals several marked differences between charcoals and even on the same charcoal. A vitrification description along the transverse wood section has been implemented. The development of an ethnoanthracological approach is essential, because it offers the possibility of collecting and comparing charcoals of the same species, but carbonized into different traditional structures, which means not in the same burning atmosphere.
