Chemical Analysis of Glass Beads From Medieval Al‐basra (Morocco)

Abstract: This paper reports the results of elemental analysis, using laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS), of 30 glass beads from an assemblage of beads excavated at medieval al‐Basra, Morocco. Six chemical glass types are represented and their characteristics and geographical origins are discussed, with reference also to the techniques used to make the beads. The presence of numerous beads of lead–silica glasses is of particular interest. The morphological, technological and chem… Show more

“…This method has been widely and successfully used for elemental analysis of historic glasses [5, 11, 21, 2629], although the lack of suitable matrix-matched solid standards is still recognized as an important limitation and prevents insights into the accuracy achievable with this technique.…”

“…It can be assumed that the results obtained by several laboratories should be more reliable then indicative information about the contents of the oxides calculated for the second group, although Corning archeological reference glasses are not characterized by a metrologically valid procedure. These glasses have been mainly used for estimation of the precision and accuracy of measurements in several investigations of historic glass objects [5, 11, 17, 27, 29, 30, 3340], because large amounts of elemental concentration data have been published for them [11, 27, 31, 32, 3740 ] . The contents of the literature values of the oxides used in this study are from Vicenzi [32] who referred to Brill [2] (Table 1).…”

“…There is a slightly similar situation in the case of glass with a high lead content with a lead‐ash type of glass that was widespread in the Early Middle Ages, including the Middle East, North‐West Africa (Morocco), Central‐Western Europe, the British Isles, as well as Central and Eastern Europe (Krueger ; Pollak ; Robertshaw et al . ; Wajda ). In the last few years, the concept about the main centres of production of this type of glass have changed considerably.…”

“…The extent to which glass was made or recycled in areas linked by, or to trans-Saharan trade routes remains unclear. The currently available evidence does not pre-date the Islamic period and is mainly concentrated in West Africa (e.g., Cissé, 2010, 206-15;Robertshaw et al 2010;Freestone, 2006;Lankton et al 2006). by Charles Daniels, and currently stored at the University of Leicester.…”

“…A major aim has been to determine the provenance of glasses, especially beads (e.g., Brill, 1994;Dussubieux, 2010;Robertshaw et al 2010Robertshaw et al , 2014, with a view to reconstructing trade routes. Vessel glass is more rarely encountered, but by the 9th and 10th centuries was certainly heading south along the West African gold trade routes (Insoll, 1996, 63-7;Insoll, 1998;McIntosh, 1995, 247).…”
