Article

Analytical data of Roman and early Islamic glass established several primary glass production groups linked to glassmaking centres in the Levant and in Egypt. In contrast, the activities of secondary glass workshops are largely invisible in the compositional fingerprint of first millennium glass. Laser ablation inductively coupled plasma mass spect...
Article
It has long been assumed that lead glazing technology preceded glassmaking in the Western world and that the technological transfer was from glazes to glass. Here, we present new evidence for the reverse, the indigenous innovation of glassmaking and its transfer to glazes in early Islamic al-Andalus (Spain). Compositional analyses show that Islamic...

Recent archaeological excavations carried out in the western suburbs of Cordoba (Spain) brought to light numerous fragments of archaeological glass from the caliphal period (929-1031 CE). The typological and compositional analysis by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of 66 fragments enabled the identification o...

Abstract: Glass from al-Andalus has received little attention from specialized research. Recent progress has shown its interest not only from a formal perspective, but also as an auxiliary source in understanding various aspects of Andalusian society. In this paper, we have compiled in a very synthetic way what we know so far about glass in al-Anda...

Among the finds from Šaqunda is a stained glass (luster) fragment (MIR 051) exhibiting compositional features similar to those of the compositional group Egypt 2, dated from the last quarter of the eighth century to the second half of the ninth century C.E.4 It has an exceptionally low alumina concentration (Al2O3 < 1.5%), a relatively low strontiu...

Significance The Islamic conquest of the Mediterranean has long been associated with fundamental geopolitical and economic transformations that sundered the medieval world from antiquity. An eighth- to ninth-century glass assemblage from Cordoba provides new insights into the processes of technological innovation, adaptation, and dissemination cont...

Excavations at the Roman villa of Noheda (Spain) revealed the remains of an exceptionally elaborate fourth-century floor mosaic that contains a surprisingly large number of glass tesserae, representing a broad spectrum of colors. This paper presents the results of the chemical (LA-ICP-MS) and microstructural analyses (SEM-EDS, XRPD) of 420 glass te...

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-induc...

This paper discusses the LA-ICP-MS analysis of two well dated glass objects from Cabezo Pardo (Alicante), the first ones to be published in the Iberian Peninsula that date to the early Emiral period. The data characterise the fragments as soda lime silica glasses made using natron as flux. Compositionally, they correspond to two of the most widespr...

The study of glass in Islamic Spain and especially from the Taifa period (11th c.) has received little attention from scholars. The present work reviews the main Arab sources that provide insights into the use and significance of glass in the Taifa of Toledo and contrasts the textual sources with the typological and compositional characteristics of...

The castle of Gauzón on the north coast of Spain controlled access to the Avilés estuary and was intimately linked to the Asturian monarchy. With the intention of studying the medieval glass trade networks in the kingdom of Asturias and León, the chemical composition of twenty-four glass samples from recent excavations at the castle were determined...

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...

This article presents the typological study of the glass assemblage from the Ciudad de Vascos (Naval - moralejo, Toledo) (10th - 11th century CE) that is now housed in the Museum of Santa Cruz in Toledo (Spain). Glass was evidently scarce at the Ciudad de Vascos. Accordingly, only a limited number of frag- ments have been recovered during the f...

Project
Medieval and Modern Iberia had a central role in the production, consumption and trade of glass in a global scale. This project is devoted to explore the origin, production and distribution of the glass and its raw materials in the Iberian cities in late Medieval and early Modern times. The project focuses on the Iberian Peninsula (Spain and Portugal) and the Macaronesia between the 14th and 16th centuries. It has a multidisciplinary approach that combines analytical data with archaeological records, typological patterns, geographical distribution, geology and textual sources to gain insights into the technology, commercial trends and raw materials of glass in this period.
