LA-ICP-MS analysis of Late Bronze Age blue glass beads from Gurob,Egypt

Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis was undertaken on 37 blue glass beads excavated from a tomb in the southern Faiyum region of northern Egypt. The tomb was undisturbed, contained the remains of seven females and two children, and dated between the reigns of Amenhotep I (1525–1504 bce ) and Tuthmosis III (1479–1425 bce ). The glass beads were coloured by copper and the trace element concentrations were compositionally consistent with glasses from Mesopotamia rather than from Egypt. Therefore, these glass beads represent a rare example of Mesopotamian glass to be discovered in Egypt, in addition to being some of the earliest glass found. Gurob is known to have been the site of a ‘harem palace' established in the reign of Tuthmosis III, the implication being that these beads represent luxury items transported to Egypt by high-ranking foreign women, possibly in connection with the harem palace.     

Classification of the Amber Beads of the Hungarian Bronze Age

Abstract

Spectroscopic provenance analysis of Hungarian amber artifacts has shown that nearly all of them are of Baltic amber or succinite, which occurs naturally only in northern Europe. The present paper explores the question whether these beads were made in northern Europe and imported into Hungary as finished products, or were made in Hungary from imported raw material.

To this end, 659 extant amber beads of the Bronze Age of Hungary are divided into 17 types by shape and dimensions. The significance of the typology is borne out by striking diachronical patterns: e.g., flattened globular beads (Group III) are virtually limited to the Middle Bronze Age, while truncated bi-conical beads (Group IX) are essentially exclusive to the Late Bronze Age. By comparing Hungarian bead forms of a given period with those of countries to the north, including Denmark and the Baltic States, the classification offers a means by which imported beads may be distinguished from locally made beads.     

Bronze and Iron Age Amber Artifacts in Croatia and Bosnia-Hercegovina

Abstract

The question as to whether or not Yugoslavia played a role in the Bronze Age amber trade to Greece has traditionally been answered negatively because of the scarcity of amber finds in that country. Amber finds that have come to light as a result of more intensive exploration after World War II have been thought to be of local origin by some Yugoslav scholars. Spectroscopic analysis of 35 archaeological amber artifacts from the Yugoslav provinces of Croatia and Bosnia-Hercegovina of the Bronze and Iron Age shows 31 of them to be of imported Baltic amber. The finds are discussed in their archaeological and geographic contexts as a first step towards re-assessing the place of the Eastern Adriatic area in the southward movement of amber.     

Between east and west: Glass beads from the eighth to third centuries bce from Poland

The study analyses the chemical composition of 57 glass samples from 40 beads discovered at 20 archaeological sites in Poland. The beads are dated to Hallstatt C–Early La Tène periods (c.800/750–260/250 bce ). Analyses were carried out using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Two groups were distinguished among the glasses based on the MgO/K₂O ratio: high-magnesium glass (HMG), five samples; and low-magnesium glass (LMG), 52 samples. The former were melted with halophyte plant ash, the second with mineral soda. These glasses were produced in the Eastern Mediterranean (more likely in Mesopotamia or Syro-Palestine than in Egypt) and transported in the form of semi-products to secondary glass workshops in Europe. Some of the white opaque glass was coloured and opacified in Europe.     

An early Iron Age assemblage of faience beads from Ashkelon,Israel: chemical composition and manufacturing process

The microstructure and chemical composition of eight faience beads from an early Iron Age (12th century BCE) assemblage found in the ancient city port of Ashkelon (Israel) are determined by means of FTIR spectrometry, pXRF, microRaman and SEM-EDS analysis. The results are compared with published data of Egyptian and Near Eastern artifacts. Each sample exhibits a hue which is obtained by adding a specific colorant to the glazing mixture. A new gray chalcopyrite-manganese-based colorant was identified. Cementation glazing was most likely used in the manufacturing process of the specimens analyzed, except for the blue bead, which is an Egyptian blue frit. The results suggest that these objects represent a unique assemblage, quite different from contemporary Egyptian and Near Eastern materials, and provide new information regarding the Iron Age faience evidence in the southern Levant.     

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 range of glass colours and the skill of their application at Nuzi was perhaps not on a par with the Egyptian sites. This led to a reconsideration and review of the accepted wisdom that the Near East is the source of the innovation that is glass‐making. This opinion is based on limited textual and iconographic sources and is dominated by an erroneous early date for a very developed Nuzi glass industry along with a few finds of glass vessels in early contexts. Some of this evidence has now been at least questioned, suggesting that glass‐making in Egypt, at least as early as the middle of the 15th century bc , and probably earlier, is no later than that in the Near East. It is argued that it is far from clear that the Near East was the source of the innovation and that a more cautious approach would better fit the evidence.     

Middle Bronze Age metallurgy in the Levant: evidence from the weapons of Byblos

This paper constitutes a synthesis of a technological investigation on copper base alloy weapons from Byblos. Most of the weapons are typical of the Middle Bronze Age in the Levant. Methods such as metallographic examination and chemical analyses by EDS were used to identify the different stages of the chaîne opératoire used in the making of these weapons. The results reveal precise information regarding the production of several types of weapons such as the type and performance of the moulds used for casting and the deformation process. Furthermore, these results highlight the contribution of economic and cultural factors in the choice of components in a copper base alloy recipe. Finally, the use of silver–copper brazes for joining copper base alloy objects is recorded for the first time for the period and region concerned.

Long distance trinket trade: Early Bronze Age obsidian from the Negev

The discovery of three small obsidian flakes at the Camel Site in the central Negev, Israel, constitutes the first discovery of obsidian in Early Bronze Age contexts in the Negev and Sinai. Obsidian hydration analysis and X-ray microprobe analysis confirm the association of the artifacts with the site and the period, and indicate origins in Eastern Anatolia, in significant contrast to the exclusively Central Anatolian source of Southern PPNB obsidian. The structure of the obsidian trade system in the Early Bronze Age seems to contrast significantly with its Neolithic predecessor, and may be related to a system of pastoral nomadic exchange.     

Investigation of Iron Age north-eastern Scottish glass beads using element analysis with LA-ICP-MS

Class 13 and 14 Iron Age Scottish glass beads are a group of highly decorated beads of British origin or design, dating indicatively to the 1st and 2nd century AD and typically found in Aberdeenshire and Moray district (Guido, 1978, 85–9). Their distinctive stylistic characteristics and geographical segregation renders them ideal for the investigation of whether the glasses employed in their manufacture were imported rather than produced locally, and for the assessment of the technology used in the production of the deep colours. Studies performed in the 1980s on different specimens pertaining to the same Classes (Henderson, 1982) showed compositional characteristics differing from Iron Age southern British beads, suggesting a different source of glass for their manufacture. Here, a set of 19 beads which was never investigated before was analysed for 32 major, minor and trace elements using Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The sample set shows good homogeneity in major and minor element composition, indicating the use of imported natron glass, with standardized composition typical of Roman glass of the period, also reflected in the recipes used for colouration. Evidence for the use of cullet and waste glass was found, which, along with the particularity of the design, suggests a local origin of the beads and possible production by native glassworkers.

Al-Khidr site on Failaka Island in the Bronze Age: Pottery perspective

The objective of this article is to evaluate the results of the excavation at the site of Al-Khidr on Failaka Island that was probably a port or a fishermen’s settlement in the past. A very large number of stone architectural remains and artifacts have been discovered there. Al-Khidr is a typical Dilmun culture site and the settlement was probably contemporary with the known sites F3 and F6 located on the south-west coast of the island. Based on the pottery that has been processed, we preliminarily dated the site to a period between the beginning of the second millenium and approximately 1500 BC, although older settlement may have occurred, beginning at the end of the third millennium.     

Pre-Roman coloured glass beads from the Iberian Peninsula: a chemico-physical characterisation study

This paper reports results derived from a chemical and microstructural characterisation study undertaken on a representative sample set of coloured glass beads that recent archaeological fieldwork carried out in the second century BC Celtiberian necropolis of Numantia (Upper Duero Valley, Spain) has provided. The main objectives of the research were to understand the production technology and provide some insights into their probable provenance. In addition, corrosion and decay processes were also assessed to determine the influence of the cremation ritual within the beads structure. The resulting data suggest that both soda-lime-silicate and, probably, alumino-silicate glasses were produced in the making of these glassy materials, using some transition metal oxides as chromophores or colouring agents. The compositional evidence gathered also suggests that Numantian glass beads were the outcome of trade or exchange practices rather than locally produced.
