The WINDOWGLASSMED project fostered several collaborations for each of the macro-areas included for the project:
• Soren Sindbaek (Aarhus University) and Lene Feveile (Ribe Vikingcentre) for the site of Ribe, Denmark.
• Professor Skre (Oslo University and Kulturhistorisk Museum - Oslo) for the site of Kaupang (Norway).
• Dr Ulriksen (Museum Sydøstdanmark) for the site of Vester Egesborg (Denmark).
• Dr Morìn de Pablos (Department of Cultural Heritage Resources of AUDEMA, Madrid) for the site of Los Hitos, (Spain).
• David Govantes-Edwards (Universidad de Córdoba) for the site of Tarragona, (Spain).
• Professor Olmo Enciso (University of Alcalá) and David Govantes-Edwards (Universidad de Córdoba) for the site of Reccopolis (Spain).
• Dr Silvestri and Dr Marcante (University of Padova) for the site of Aquileia, Brescia, Grado, Monselice, Monte Barro, and Vicenza (Italy).
• Professor Chavarria (University of Padova) the site of Battistero of Padova Duomo, Italy.
• Ministry of Cultural Heritage- Soprintendenza del Molise (

• Professor Bianchi (University of Siena) for the site of Vetricella (Italy).
LA-ICP-MS analysis has been carried out on 399 samples during two secondment periods in Chicago, Fields Museum (USA) in collaboration with Dr Dussubieux; the second period took place in Keyworth, Nottingham (UK) at British Geological Society collaboration with Dr Chenery at Keyworth, BGS (UK).
A NERC grant (10.500£) has been secured to perform isotopic analysis (Sr, Nd, and Hf) on twenty samples in collaboration with Dr Ian Millar (BGS, Keyworth). Analysis will be carried out in early 2024.
An R environment suitable for glass data analysis has been created and exploited for data analysis.
A database for EM Western glass and available comparison data paired with Geochemical data has been created and will be published on the Archaeology Data Service (
https://archaeologydataservice.ac.uk/(opens in new window)) after the publication of the articles.
The framework behind of the WINDOWGLASSMED project has been discussed during the proceedings of “Le forme del vetro. Tecnologie a confronto. Produzioni vitree e invetriate in Sicilia, Italia peninsulare e al-Andalus tra IX e XII secolo” (

As a result, an article is currently in publication at the time of this report and it will be soon available in the Mélanges de l'École française de Rome - Moyen Âge (MEFRM) (

Four articles are in currently preparation as a result of the WINDOWGLASSMED project. For each macro production area (Italy, Spain, and Scandinavia) chemical results will be presented and discussed in order to highlight production, recycling and trade patterns for Western European glass. The last publication will be focusing only on the isotopic data results (Sr, Nd, Hf) to assess the provenance of Western European glass, refine production patterns and trade route suggestions.
