The ceramostratigraphy has to be examined in the light of other dating methods in order to serve as a chronological reference, where, in the case of Saint-Blaise/Bains des Dames, it was confronted with typology, dendrochronology, and the stratigraphy. Dendrochronology is a method of absolute dating that can furnish the precise year in which a structure was built; the study of wood chips, and the correlation between posts from different periods and the archaeological material were fundamental factors for our research. Indeed, a functional (chronological) correlation was postulated between the permanent structures (habitation) of the site and the movables (potsherds) recovered during the excavation. The purpose of the successive confrontations was to provide each assemblage with a coherent date.
