“…The second largest group represented at Vascos (37) are natron-type glasses of the Roman tradition [22]. Finally, there is a small set of six fragments with high lead contents (40–48%), similar to glasses previously described in medieval Islamic contexts [4–7, 23]. Five samples are classified as outliers, because they show unusual compositional features and cannot be attributed to any of the groups with certainty.…”

One hundred and forty-one glass fragments from medieval Ciudad de Vascos (Toledo, Spain) were analysed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The glasses fall into three types according to the fluxing agents used: mineral natron, soda-rich plant ash, and a combination of soda ash and lead. The natron glasses can be assigned to various established primary production groups of eastern Mediterranean provenance. Different types of plant ash glasses indicate differences in the silica source as well as the plant ash component, reflecting changing supply mechanisms. While the earlier plant ash groups can be related to Islamic glasses from the Near East, both in terms of typology and composition, the chemical signature of the later samples appear to be specific to glass from the Iberian Peninsula. This has important implications for our understanding of the emerging glass industry in Spain and the distribution patterns of glass groups and raw materials. The plant ash that was used for the Vascos glasses is rich in soda with low levels of potash, similar to ash produced in the eastern Mediterranean. It could therefore be possible that Levantine plant ash was imported and used in Islamic period glass workshops in Spain. Unlike central and northern Europe where an independent glass industry based on potassium-rich wood ash developed during the Carolingian period, the prevalence of soda ash and soda ash lead glass on the Iberian Peninsula indicates its commercial and technological interconnection with the Islamic east. Our study thus traces several stages leading to the development of a specifically Spanish primary glassmaking industry.

“…Given the overlap of the two groups at low iron concentrations, a second criterion was applied, whereby all samples with Fe 2 O 3 < 2% were attributed to HIMTa. Data were taken from Rius et al (), Mirti et al (), Freestone et al (, ), Foy et al (), Uhlir (), Arletti et al (, ), Wolf et al (), Blin and Vanpeene (), Gómez‐Tubío et al (), Carmona et al (), Da Cruz (), Foster and Jackson (), Rehren et al (), Castelo et al (–12), Schibille (), Palomar et al (), Schiavon et al (), Schibille et al (, ), Conte et al (), Möncke et al (), Rosenow and Rehren (), Agua et al (), Di Bella et al (), Gliozzo et al (), Gliozzo et al (,b, ,b), Maltoni et al (, ), Rehren and Brüggler (), Jackson and Paynter (), Smith et al (), Ceglia et al (), De Juan Ares and Schibille (,b) and Siu et al ().

“…Even though, from a typological point of view, the materials do not seem to postdate the first half of the fifth century, there are a few samples for which a date in the first decades of the sixth century cannot be ruled out (Table S1). Hence, our new analytical data address the supply of late Roman glass to the Iberian Peninsula at the time when glass compositions diversified (De Juan and Schibille ,b). To resolve the networks of exchange, we compared the analytical results from Picola with the compositional data of contemporary glass assemblages.…”

“…Less is known about the spatio‐temporal distribution patterns of these glass groups because of the uneven spread of the evidence. A major gap in glass studies, for example, consists in a near‐complete lack of reliable analytical data from the Iberian Peninsula (De Juan and Schibille ). Iberia, with its well‐documented exchange across the Roman Empire, provides a fertile ground for the investigation of glass as a proxy to re‐evaluate economic connections and possible trade routes.…”

The Supply of Glass at Portus Ilicitanus (Alicante, Spain): A Meta‐Analysis of HIMT Glasses

et al. 2018

Portus Ilicitanus (Picola, Alicante) was the main sea harbour of the Roman Colonia Iulia Ilici Augusta and as such played a crucial role in the supply of fundamental commodities to the Iberian Peninsula. Excavations yielded large quantities of glass in fourth‐ and early fifth‐century contexts. Elemental analysis of 60 samples by laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) confirmed that the glasses were imported from the Eastern Mediterranean. A majority of the glasses correspond to the HIMTa primary production group, which originates from Egypt. The statistical evaluation of published data of 589 HIMT glasses further revealed differential distribution patterns of the HIMTa and HIMTb subtypes between the Eastern and Western Mediterranean, suggesting chronological trends that are linked to wider geopolitical changes. This demonstrates the need for systematic large‐scale approaches to identify supply patterns and possible factors underlying geographical differences and/or chronological developments.
