Studio archeologico e petro-archeometrico delle teglie con prese a linguetta (Lappenbecken) nell’arco alpino centro-orientale

The Lappenbecken pans are ceramic artefacts typical of Roman and Late Roman contexts, in the area of Brescia. The discovery of these pans in some unpublished sites of Valcamonica (Berzo Demo, Capo di Ponte, Darfo Boario, Breno) allowed us to carry out the archaeological study together with a preliminary archaeometric investigation on a large number of sherds. Compositional data have been collected on macroscopic samples and on a selection of thin sections, observed under the polarizing microscope. Peculiar features of different paste groups, in term of petrography and fabric, have been individuated, as well as technological skills corresponding to different way of making pottery. Archaeological and archaeometric analyses allowed us to refer the complete production cycle of Lappenbecken pans to a household context, decidedly local, as documented by the presence of minerals and rock fragments related to the geology of Valcamonica (i.e.: hornblende; tonalite of the Adamello complex; volcanic rocks; micaschists).
