AbstractThis study presents the results of the petrographic and geochemical analyses of the entire pottery assemblage discovered at the sixth-century (AD) cemetery of Szólád, Western Hungary, associated with the Langobard era in the territory of the former Roman province of Pannonia. Szólád is one of the most prominent archaeological sites of this period, where prior studies have shown that the cemetery was used for ca. one or two generations by a migrating group of diverse genetic background. The present work is the first integrated typological and archaeological science pottery analysis from the early migration period (fifth to sixth century) Hungary. We applied polarising light optical microscopy (OM), prompt gamma activation analysis (PGAA), and neutron activation analysis (NAA) on all samples and, additionally, scanning electron microscopy equipped with energy dispersive spectrometry (SEM–EDS) on one selected sample. One main fabric group with three subgroups were defined by OM, to which the majority of the samples belong. This fabric group was characterised by aplastic inclusions derived from a carbonate-cemented sandstone typical of the environs of Szólád; therefore, the vessels of this fabric group appear to have been produced locally. The remaining four samples display a variety of unique, ungrouped, fabrics (loners) indicative of different recipes and/or the presence of pottery originating from outside of the region. Our study concludes that the community associated with the cemetery favoured burying pots with the deceased that stylistically resembled archaic “Elbe Germanic” traditions, but which were in fact made locally. However, in some cases, relationships with more distant territories and cultural traditions are also represented.

AbstractEight ornaments and a dagger were analyzed using completely non-destructive techniques to determine their alloy compositions and to draw conclusions about the production technology. Prompt-gamma activation analysis and time-of-flight neutron diffraction proved that the studied objects are tin-bronzes. Difference was observed in the amounts of ore-related minor components (arsenic, silver, nickel) of the objects belonging to the two distinct archaeological sites. Based on the diffraction analysis of the microstructure, the objects are casts that were exposed to different degrees of manufacturing to reach their final forms.

We present precise analysis of major and trace elements of the humic acid. We used three different element analytical techniques in our investigations as prompt-gamma activation analysis (PGAA), neutron activation analysis (NAA) and X-ray fluorescence (XRF) analysis was carried out. We identified 42 elements in our sample.

The production and manufacturing techniques of metals involve expertise, and the study of ancient artifacts relies on interdisciplinary skills. Metalworking processes used in the production of jewelry masterpieces can, for example, give indications on the provenance of an ancient object of an unknown origin and the techniques used. In this regard, metallic samples from the Chiaravalle Cross (a beautiful processional cross with a complex structure, dating to the 13th century) have been studied, combining bulk and point measurements. Neutron-based experiments (like Prompt Gamma Activation Analysis and neutron diffraction) provide the bulk of the elemental and mineralogical composition, while particle induced X-ray emission analyses evidenced important details on its manufacturing techniques.
