Plant-ash glass in Natronland
This article examines available evidence for the use of plant ashes in glassmaking in the Mediterranean basin and Europe from the 1st to the 8th-9th century CE. During this period, glassmaking in these regions was overwhelmingly dominated by mineral fluxes, primarily natron, but the chemical composition of some glasses found in secure archaeological contexts suggests the use of plant ashes in these glasses, which are, on the other hand, compositi…
Early Use of Lime Mortar at the Early Iron Age Piscina Torta Salt Production Site (Tiber Delta, Ostia, Italy)
This study presents new evidence for the early use of lime mortar during the Early Iron Age at the Piscina Torta site (Ostia, Italy), situated on the earliest Holocene beach ridges in the southern Tiber delta. The site, which was earlier described as a briquetage site, dates from between the late 8th and 6th century BCE and consists of a large complex of dumps, holding kilns and working floors. Lime mortar‐like materials were abundantly present i…

Exploring circulation dynamics in Han Dynasty China
This study investigates lead provenance and circulation patterns in Han Dynasty (202BC-220AD) China through the analysis of lead glazed pottery. Four objects were studied using a combination of typological study, elemental chemistry and lead isotope ratio analysis. The results for each object were compared with databases of 'lead mining districts' (lead deposits) and 'lead usage districts' (lead-containing artifacts unearthed in different spatial…
The Amulets from the Carthaginian tophet
Amulets found in burial urns of the Carthaginian tophet are discussed in terms of frequency of occurrence, and the nature and chronology of their material composition. Amulets were added in only 31 % of the urns studied, exclusively to urns containing human remains, with glass, faience, gold and silver the most common materials used. Chemical analysis of a selection of glass and silver amulets identified the primary origin of raw materials used i…
Uniformity in Tophet Ceramics
Burial urns and lids found in the Carthage tophet precinct play a pivotal role in our understanding of material trajectories. Significant differences in macroscopic features present problems as to where and how these vessels were made. In general, issues in sourcing north African ceramic materials stem from their compositional homogeneity, having mostly sand and calcareous fractions varying to a greater or lesser degree. In this paper we present …

Magical practices? A non-normative Roman imperial cremation at Sagalassos
Many thousands of burials have been excavated from across the Roman world, documenting a variety of funerary practices and rites. Individual burials, however, sometimes stand out for their atypical characteristics. The authors report the discovery of a cremation burial from ancient Sagalassos that differs from contemporaneous funerary deposits. In this specific context, the cremated human remains were not retrieved but buried in situ, surrounded …

A review of soil geochemistry in archaeology
Trace metal analysis of archaeological soils has grown in popularity in recent decades, as an additional means of measuring human impact on and off archaeological sites. Nonetheless there has been a tendency to ascribe such elements too easily to ancient metallurgy, whereas pollution research studies have identified many other causes of heightened trace metals in anthropogenic deposits. This article reviews the published history of research into …

Isotopic Discriminants Between Late Bronze Age Glasses From Egypt and the Near East
This paper presents oxygen, strontium and neodymium isotopic analysis from a series of Late Bronze Age glasses from Egypt and Mesopotamia. It was found that oxygen and neodymium isotopes alone cannot readily distinguish between glasses from the various sites. However, combined Sr and Nd isotope analysis separate the data into three groups: an Egyptian group with relatively low Sr and Nd ratios; a Late Bronze Age (LBA) Nuzi group with high Sr and …
The Analysis of Late Bronze Age Glass from Nuzi and the Question of the Origin of Glass‐Making
This paper re‐analyses a considerable corpus of glass from the Late Bronze Age site of Nuzi, found near Kirkuk in Iraq. SEM–WDS and Sr and Nd isotopic analysis were applied, in addition to cataloguing the glass. The work showed that the glass technology at Nuzi was subtly different from contemporary Egyptian sites, using different ways of opacifying and working glass. At least two, perhaps three, Near Eastern production sites are postulated. The …
New Data on the Soda Flux Used in the Production of Iznik Glazes and Byzantine Glasses
Previous research has shown that Iznik glazes are characterized by low potash and magnesia contents. It was therefore suggested that the flux used was either a purified plant ash or some unidentified mineral source of soda. More recently, as a result of the detection of small, but significant, amounts of boron and lithium in Byzantine glasses from western Turkey, which also exhibit low potash and magnesia contents, it has been suggested that the …
Isotopes on the Beach, Part 1
The provenancing of Roman natron glass is one of the most challenging problems in the field of archaeometry. Although the use of Sr and Nd isotope ratios and trace element signatures as an indication of provenance has proven promising, there are still many unknowns. In this study, the influence of the different raw materials on the final Sr isotopic composition of Roman natron glass is examined. It is shown that the 87 Sr/ 86 Sr ratio in natron g…

of soot, with no metal spheres and contain particles of charcoal. The compostition of the silicated coating suggest metal melting temperatures around 1 300 to 1 400 °C. The presence of Ni and Sn within the silicated coating on the globules can be a usable trace to determine the source of the metal used in Bavay
The sigillata manufactories of Pergamon and Sagalassos
The Late Hellenistic period saw the intensification of pottery mass-production processes, of which Eastern Sigillata may be considered the pearl in the crown. Reddish tableware had a long tradition in the Levant and its evolution culminated around 150 B.C., in the region between Tarsos and Laodikeia, with the production of Eastern Sigillata A (ESA). More or less simultaneously, but independently, the manufacturing of Eastern Sigillata C (ESC) was…
The Concept of a Pottery Production Centre. An Archaeometrical Contribution from Ancient Sagalassos
Geoarchaeological investigations of the “potters' quarter” at Sagalassos, southwest Turkey
The potters' quarter of the ancient city of Sagalassos, southwest Turkey, was one of the largest and most enduring ceramic‐producing manufactories in the eastern Mediterranean. The objective of our study was to determine environmental circumstances that favored development of different clay resources in the territory of Sagalassos and to assess utilization of these resources in the local pottery manufactory. The potters' quarter was established w…
Pollen sequences from the city of Sagalassos (Pisidia, southwest Turkey)
Two pollen sequences from the Classical city of Sagalassos (Pisidia, southwest Turkey) show that the hills just north of the city were forested during the main occupation period of the city (late Hellenistic to early Byzantine). They demonstrate that there was a mixed needle-leaved forest of Pinus, Cedrus libani and Abies cilicica . The platform on which the city sat was already deforested, as is indicated by the presence of pollen from various l…

Compositional Variation in Roman Colourless Glass Objects From the Bocholtz Burial (The Netherlands)
We investigated the major and trace element composition and Pb and Sr isotope characteristics of a series of about 20 colourless glass objects from a single high‐status Roman burial from the Netherlands (Bocholtz). The major elements show a relatively homogeneous group, with one outlier. This is corroborated by the Sr isotopes. Based on the Sb and Pb content, three major groups can be discerned, with two other outliers. This grouping is corrobora…
Combined Pb-Sr isotopic analysis in provenancing late Roman iron raw materials in the territory of Sagalassos (SW Turkey)
In early Roman times, iron was likely supplied to the city of Sagalassos through the smelting of close-by hematite ores. In the early Byzantine period, magnetite-titanite placer sands in some instances could have been exploited for its iron. For the intermediate late Roman period, however, the source of the locally used iron was unknown. Pb and Sr isotopic analyses of iron ores from the area of Camoluk, just south of the territory of Sagalassos, …
