In the past couple of years, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been widely used for trace element analysis in solid samples and the study of their...
The study contains the latest knowledge concerning glass production at the beginning of the High Middle Ages in one of the oldest glass production areas in the Ore Mountains consisting of three glassworks located in the upper reaches of the mountains. The work presents archaeological sources obtained in excavations at the Jilmová I, II and III sites, with attention being focused on finds specific to glass production centres, i.e., mainly fragments of technical ceramics – melting pots, crucibles and the waste accompanying various stages of glass production. The classic typologicalmorphological analysis is accompanied by a detailed archaeometric analysis. The results of spectrometric analyses (XRF, XRD, SEM–EDS and LA–ICP–MS) expand the informative value of archaeological finds and help refine existing knowledge of glass production technology in the second half of the 13th century.
With its at least 100 graves, the Migration period cemetery in Záluží by Čelákovice, Praha-východ district, investigated in the 1920s and 1930s ranks among the largest and most important sites from the end of the 5th to the middle of the 6th century AD in Bohemia. The same applies to the assemblage of glass composed of 168 beads and several additional artefacts. The chemical composition of the glass of 24 beads was identified using SEM-EDS and LA-ICP-MS. The results of these analyses indicated soda-lime glass of the natron type. An important result is the finding that translucent glasses belong to the ‘Intermediate group’, which was only recently identified in European archaeometric research. The composition of the glass in this group indicates that it was recycled glass, and in this sense the beads from Záluží contribute to the study of recycling in the first millennium AD in general.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
