Plant-ash glass in Natronland: A review of the use of plant-based fluxes in glassmaking from the 1st to the 9th century CE in Europe and the Mediterranean basin
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…
Neutron tomography reveals extensive modern modification in Iron Age Iranian swords
Early Iron Age Iranian bladed weaponry plays a significant role in discussions of metallurgical development in the ancient Near East. Due to its ubiquity in museum collections, as well as co-occurrence of bronze, iron, and bimetallic forms, it figures prominently in debates about the early ironworking techniques in the late 2nd and early 1st millennia BCE. However, dispersed collections, often lacking secure archaeological context, have made comp…
The dating and provenance of glass fragments from the site of Serabit el-Khâdim, Sinai
Serabit el-Khâdim, located on the western coast of the Sinai Peninsula, is the site of an ancient turquoise mine established in the early 12th Dynasty (c. 1985 BCE) and active between the 18th and 20th Dynasties (c. 1550–1136 BCE). The temple dedicated to Hathor at Serabit detail the number of offerings made, thereby recording the level of activity at Serabit during each reign. The last offerings were made by Rameses VI (1143–1136 BCE) correspond…
The government behind insurance governance: Lessons for ransomware
The insurance as governance literature focuses on the ability of private enterprises to collectively regulate, pool, and distribute risks. This paper analyzes how governments support insurance markets to maintain insurability and limit risks to society. We propose a new conceptual framework grouping government interventions into three dimensions: regulation of risky activity, public investment in risk reduction, and co‐insurance. We apply this fr…
Characterising Chinese Ru ware in the Sir Percival David collection at the British Museum using handheld XRF analysis
Ru ware is a very rare and highly prized stoneware from the end of the Northern Song period of China (960–1127 CE). Stylistic and art historical work by Regina Krahl (2021) suggests that a brush washer in the Sir Percival David Collection, housed in the British Museum, might be Ru rather than Korean Goryeo ware as previously thought. This paper reports the analysis of the glaze of this piece by handheld XRF in comparison with 10 pieces of Ru and …
The transformation of the art market: Law, norms, and institutions
Over the last three decades, the art market has undergone a remarkable transformation. Before the 1990s, artworks were sold with hardly any concern about whether they had been stolen or looted, whereas now any reputable gallery or auction house checks the “provenance” of any substantial work before sale. This transformation reflects interlocking changes in law, norms, and institutions. New York’s and more broadly the United States’ assertion of j…
Technological connections in the development of 18th and 19th century Chinese painted enamels
Chinese painted enamel is an artistic tradition of enamelled copperwares developed during the Kangxi period (1662–1722), commonly referred to as Canton enamel after the Wade-Giles spelling of Guangzhou. In this study, enamel fragments from areas of damage in the decorated surface of ten Chinese painted enamel objects dating to the 18th and early 19th century in the collections of the Ashmolean and Fitzwilliam Museums were non-destructively analys…
The investigation and provenance of glass vessel fragments attributed to the Tomb of Amenhotep II, KV35, Valley of the Kings
Four polychrome glass fragments, excavated from tomb KV35 in the Valley of the Kings, attributed to Amenhotep II, were analysed to further investigate the composition and provenance of early Late Bronze Age (LBA) glasses. An additional fragment, EA64163, cited by the British Museum as being stylistically analogous to the fragments from KV35, although with a findspot simply recorded as ‘Thebes’, was also analysed. Laser ablation inductively couple…
Emulation and technological adaptation in late 18th‐century cloisonné‐style Chinese painted enamels
Cloisonné‐style motifs are rare and enigmatic in Chinese painted enamels because of their distinct technological development at the end of the 18th century. Five late Qianlong to Jiaqing period (1736–1820) Chinese painted enamels with cloisonné‐style motifs are investigated using environmental scanning electron microscopy–energy dispersive X‐ray spectroscopy. Back‐scattered electron images and elemental analysis are combined to study the decorati…
Interpreting elements and isotopes in glass: A review
Substantial databases of elemental and isotopic analyses of ancient glass exist and are used to investigate raw material origin, trade, exchange, and processes such as mixing and recycling. However, the chemistry of archaeological glass may be challenging to the untrained. The paper provides structured information on the origin of chemical elements and their isotopes in ancient glass. It details some of the functions of individual elements in the…
Isotopic evidence for the use of Caucasian antimony in Late Bronze Age glass making
Governance under the shadow of the law: Trading high value fine art
The market for paintings by well-known artists is booming despite widespread concern about art crime and difficulties in establishing provenance. Public law enforcement is imperfect, and court cases often are deemed problematic. So how is the thriving art market governed in practice? We analyze the protocols used by the top auction houses to identify and resolve problems of illicit supply—fakes, forgeries and items with defective legal titles—thr…
Early Medieval Garnet-Inlaid Metalwork: A Comparative Analysis of Disc Brooches From Early Wessex
Garnet-inlaid metalwork was an emblem of elite culture in the early medieval North Sea world. This study compares three Anglo-Saxon garnet-inlaid brooches that are exceptionally similar in design and appearance. All three date to the seventh century, a period that saw the emergence of leading families that used such deluxe dress items to enhance their political position. The central hypothesis explored here is that the brooches were produced by t…
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 wer…
Dating and provenance of glass artefacts excavated from the ancient city of Tall Zirā‛a, Jordan
Fourteen glass objects recovered from excavations at the ancient city of Tall Zirā‛a, Jordan, were analysed using laser ablation inductively coupled plasma mass spectrometry (LA‐ICP‐MS) to determine the period and origin of manufacture. The composition of glasses manufactured in the Late Bronze Age (LBA) and Iron Age are distinctly different, therefore major element analysis can be used to distinguish between the groups relatively easily. The LA‐…
Antimony as a raw material in ancient metal and glass making: Provenancing Georgian LBA metallic Sb by isotope analysis
Sb was frequently used as a raw material, both in ancient glass-making (as an opacifier and decolouriser) and metallurgy (either as an alloying element or as a pure metal). Despite this ubiquity, antimony production has only occasionally been studied and questions concerning its provenance are still not satisfactorily answered. This study evaluates the suitability of Sb isotope analysis for provenance determination purposes, as experiments under …
“The Illusion of an Authentic Experience”: A Luster Bowl in the Ashmolean Museum
In 2014 the Ashmolean Museum conserved and examined one of the largest and most handsome ceramic vessels in its renowned Islamic art collection. An accomplished example of early thirteenth-century Persian lusterware from the bequest of Sir Alan Barlow, the salver had an unusually deformed profile and uneven wear that pointed at a number of past interventions. Some of these had already been uncovered in 2008 when the object was prepared for reinst…

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 …
Governing criminal markets: The role of private insurers in kidnap for ransom
The intersection between the formal and criminal economies presents a range of intractable coordination and enforcement problems. Who orders and facilitates the interactions between private, legal entities, and criminals (potentially) engaged in kidnap for ransom? I analyze the contracts, protocols, norms, and agencies created by insurers to govern this unusual market. Stringent insurance contracts, effective security measures, and orderly resolu…

Governing kidnap for ransom: Lloyd's as a “private regime
Kidnap for ransom raises significant governance challenges. In the absence of formal regulation and enforcement, insurers have created an effective private governance regime to facilitate smooth commercial resolutions. Controlling ransoms is paramount: “supernormal” profits for kidnappers create kidnapping booms and undermine the market for insurance. Ransom control requires cooperation, but there are high transactions costs in enforcing a collus…

New Data on the Soda Flux Used in the Production of Iznik Glazes and Byzantine Glasses: Soda flux used in 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 …
Discovery, Production and Use of Tin‐based Opacifiers in Glasses, Enamels and Glazes From the Late Iron Age Onwards: A Reassessment
Tin‐based opacifiers (lead stannate yellow and tin oxide white) were first used in glass production for a short period in Europe from the second to the first centuries bc , and then again throughout the Roman and Byzantine Empires from the fourth century ad onwards. Tin oxide was also used in the production of Islamic opaque glazes from the ninth century ad , and subsequently in enamels applied to Islamic and Venetian glasses from the 12th centur…

State-Building, Informal Governance and Organised Crime: The Case of Somali Piracy
This article argues that gangs, clans, mafias and insurgencies are, like states, forms of governance. This insight is applied to the case of Somali piracy and the article explores whether protectors of piracy were clearly distinct from pirates; and to what extent protectors coordinated their activities across the Somali coastland. It is shown that clan elders and Islamist militias facilitated piracy by protecting hijacked ships in their anchorage…

Raw Materials of Glass From Amarna and Implications for the Origins of Egyptian Glass
Analysis has been conducted on 19 blue glasses from Amarna in Middle Egypt dated to around 1350 BC. The results suggest that these glasses fall into two distinct types: cobalt coloured glasses with a natron based alkali made from local Egyptian materials, and copper coloured glasses with a plant ash alkali, which follow a Mesopotamian tradition of glass making. It is suggested that at least some of this copper/plant ash glass is imported into Egy…
The Analysis of Second Millennium Glass From Egypt and Mesopotamia, Part 1: New WDS Analyses
A recent analytical study by SEM–WDS was carried out on 226 glasses from the Late Bronze Age, analysing each of the glasses for a total of at least 22 elements, the largest such analytical study conducted on these glasses. The aim of the analysis was first to identify which elements were brought in with each of the raw materials and, second, to accurately characterize those raw materials. Since different glassmaking sites in Egypt and the Near Ea…

Production Technology for Copper‐ and Cobalt‐Blue Vitreous Materials from the New Kingdom Site of Amarna—A Reappraisal
Previously published data on the chemical compositions and microstructures of copper‐ and cobalt‐blue frit, glass and faience from the New Kingdom site of Amarna in Egypt ( Shortland 2000 ) are summarized. The data are then used to infer the raw materials and processes employed in the production of these vitreous materials. The results suggest that crushed quartz pebbles were the source of the quartz for all the materials, but that different sour…

Evaporites of the Wadi Natrun: Seasonal and Annual Variation and Its Implication for Ancient Exploitation
The evaporitic deposits of the Wadi Natrun on the edge of the Western Desert of Egypt have been used in variety of crafts and industries for over 6000 years. This paper reviews the formation processes of the evaporitic deposits between the different lakes in the wadi and for the wadi as a whole. It shows that the precipitation of sodium carbonate minerals within the lakes is seasonal and probably subject to long‐term fluctuation as climate varies…

Application of Lead Isotope Analysis to a Wide Range of Late Bronze Age Egyptian Materials
Lead isotope analysis was applied to Egyptian materials from the Late Bronze Age in order to investigate the relationship between these different materials, many of which have lead as a significant component. The galena kohls analysed can be provenanced to Gebel Zeit, a large mining site known to have been active during the period. However, the source of lead metal is different and seems to be outside Egypt, along with the source of copper. Lead‐…
Boron isotopic composition as a provenance indicator for the flux raw material in Roman natron glass
The Business of Piracy in Somalia
This article argues that understanding why Somali piracy has resisted control efforts requires understanding that it is a criminal business rather than a conventional international security problem. We statistically model Somali piracy and draw two conclusions: first, piracy increases with economic stability, and second, naval interdiction efforts are stabilising but not significantly reducing piracy. We argue that these conclusions are not surpr…
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 …

Depictions of Glass Vessels in Two Theban Tombs and Their Role in the Dating of Early Glass
Depictions of Glass Vessels in Two Theban Tombs and their Role in the Dating of Early Glass
The paintings in the tombs of Rekhmire (TT 100) and Menna (TT 69) both include depictions of glass vessels, objects that have rarely been identified in Egyptian art. Two vessels are shown in the tribute scenes of the transverse hall of TT 100 being offered by chiefs from Syria. Given its date, this scene may represent the arrival of the first man-made glass in Egypt. TT 69 has a depiction of a third vessel, shown decorated with the trailed and ma…
The Number, Extent and Distribution of the Vitreous Materials Workshops at Amarna
Excavations at Amarna, the late 18th Dynasty capital of Akhenaten, undertaken at the end of the last century and early in this century, uncovered several parts of the city where major areas of habitation coincide with manufacturing sites. This paper presents the results of an in‐depth study of the published reports and unpublished excavation day books for the 1200 individual houses so far registered at Amarna carried out by the author. This study…

Lead Isotopic Analysis of Eighteenth‐dynasty Egyptian Eyepaints and Lead Antimonate Colourants
New lead isotopic analyses are presented for lead antimonate coloured glass and faience from Amarna in Middle Egypt and dated to around 1350 BC. When compared to existing data, these suggest that Gebel Zeit on the Red Sea coast of Egypt may be the source for some of the lead antimonate colourants used in Egypt and possibly for the galena kohls of Eighteenth‐Dynasty date as well
The use and origin of antimonate colorants in early Egyptian glass
The use and origin of antimonate colorants in early Egyptian glass
The origin of the colorants in Egyptian glass of the second millennium BC has been the subject of much research and debate. Several colorants including lead antimonate yellow and calcium antimonate white appear in the archaeological record apparently concurrently with the introduction of glass, and it is possible that their origins are in some way linked. This paper examines the use of the antimonate colorants and uses analytical and experimental…

Political Violence and Excess Liquidity in Egypt
In this article we estimate a time-series model of excess liquidity in the Egyptian banking sector. While financial liberalisation and financial stability are found to have reduced excess liquidity, these effects have been offset by an increase in the number of violent political incidents arising from conflict between radical Islamic groups and the Egyptian state. The link between political events and financial outcomes provides a rationale for e…

Technological Study of Ptolemaic – Early Roman Faience From Memphis, Egypt
Fourteen fragments of faience vessels from the Ptolemaic/Roman period found at the Egyptian site of Memphis, near Cairo, were analysed by SEM. The fragments included high‐relief polychrome vessels, which are first produced in numbers in this period. Analysis allowed the composition and microstructure of the vessels to be assessed and conclusions drawn as to the raw materials of manufacture. Combining this information with archaeological evidence …

Ancient Exploitation and Use of Cobalt Alums From the Western Oases of Egypt
Cobalt alums from the Western Oases of Egypt were used in the second millennium bc as a colorant to produce dark blue glasses and glazes. A collection of these alums was gathered together and analysed by a series of techniques to accurately characterize them. They were then used alongside artificial analogues in experimental work aiming to determine the process that was used to convert the raw alum into a suitable pigment that might be used in a …

Who Were the Glassmakers? Status, Theory and Method in Mid‐second Millennium Glass Production
Glass was first produced in a regular and controlled manner in the Near East in the sixteenth century BC. This paper examines a wide variety of textual, archaeological and analytical sources to try and determine more about the makers of this first glass. It attempts to show how modern ideas about medieval glassmaking have been anachronistically applied to the second millennium BC, and readdresses this by turning instead to second millennium sourc…
