This case study examines the use of X-ray fluorescence (XRF) as an effective method for defining distinct chemical compositions of local basalt stone from different sources in the Roman period, even when their quarries have not been identified. It also deals with the archaeological question if public and monumental structures from a village and urban site shared the same stone sources and stonemason's workshops. Ninety-six samples from the Hippos Territorium, mainly from the polis of Hippos and the village of Majduliyya, were analyzed. XRF was found to be an effective method for defining distinct chemical compositions of local basalt materials from different sources. The distinct composition of the basalt stones between the two sites provided valuable insights into socio-economic relationships, shedding light on the nature of city–village dynamics in the region. Additionally, it aids in discerning whether diverse basalt sources were utilized in both private and public constructions, as well as installations within a single site. Methodological questions and the application of this method in the archaeological research of basalt-based architecture are also addressed.
Micro-X-ray fluorescence (XRF) screening of 244 glass sherds from Ribe, Denmark, identified 23 wood ash glasses. The closely dated finds pinpoint the arrival of the earliest wood ash glass produced in Western Europe in this important North Sea trading hub. This glass type was absent among glass from 700 to 790 CE but feature strongly from 790 to 810 CE. Electron microprobe analysis (EMPA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis of 24 glasses show the presence of four types. We show the strengths of classifying wood ash glass based on the glass-producing sands and conclude that the earliest production took place on a considerable scale and had a major impact on glass circulation in Northern Europe in the ninth century.
