The Neolithic Copper Melting Crucibles from Switzerland

FromRehren mine (eds) to microbe 2009, From Mine to Microscope, 155-162 155 Chapter 15 From mine to microbe – the Neolithic copper melting crucibles from Switzerland Th. Rehren1 Abstract The occurrence of chalcopyrite in several late Neolithic crucibles from NW Switzerland and SW Germany has been variously interpreted as indicating evidence for local copper smelting, or being due to post-depositional phenomena. This study uses optical microscopy and a discussion based on textural and micro-stratigraphical arguments to demonstrate that chalcopyrite is a late formation and not indicative of copper smelting. This has significant implications for the technological and archaeological interpetation of these finds, but also illustrates the potential of image-based studies in science-based archaeology.

293 Radiocarbon and Stable
RADIOCARBON, Vol 46, Nr 1, 2004, p 293–300 © 2004 by the Arizona Board of Regents on behalf of the University of Arizona RADIOCARBON AND STABLE ISOTOPE EVIDENCE OF DIETARY CHANGE FROM THE MESOLITHIC TO THE MIDDLE AGES IN THE IRON GATES: NEW RESULTS FROM LEPENSKI VIR C Bonsall1,2 • G T Cook3 • R E M Hedges4 • T F G Higham4 • C Pickard1 • I RadovanoviÊ5 ABSTRACT. A previous radiocarbon dating and stable isotope study of directly associated ungulate and human bone samples from Late Mesolithic burials at Schela Cladovei in Romania established that there is a freshwater reservoir effect of approximately 500 yr in the Iron Gates reach of the Danube River valley in southeast Europe. Using the δ15N values as an indicator of the percentage of freshwater protein in the human diet, the 14C data for 24 skeletons from the site of Lepenski Vir were corrected for this reservoir effect. The results of the paired 14C and stable isotope measurements provide evidence of substantial dietary change over the period from about 9000 BP to about 300 BP. The data from the Early Mesolithic to the Chalcolithic are consistent with a 2-component dietary system, where the linear plot of isotopic values reflects mixing between the 2 end-members to differing degrees. Typically, the individuals of Mesolithic age have much heavier δ15N signals and slightly heavier δ13C, while individuals of Early Neolithic and Chalcolithic age have lighter δ15N and δ13C values. Contrary to our earlier suggestion, there is no evidence of a substantial population that had a transitional diet midway between those that were characteristic of the Mesolithic and Neolithic. -
The Evolution of Engineering Materials
Paper ID #20611 The Evolution of Engineering Materials Dr. Amber L. Genau, University of Alabama at Birmingham Dr. Amber Genau is an assistant professor in the Materials Science and Engineering Department at the University of Alabama at Birmingham. She received her B.S. and M.S. from Iowa State University and Ph.D. from Northwestern University, all in materials engineering. Before coming to UAB, Dr. Genau spent two years as a guest scientist at the German Aerospace Center in Cologne, Germany, working on metal solidification and microstructural characterization. She is particularly interested in broadening participation in engineering and providing international experiences and perspectives to undergraduate students. c American Society for Engineering Education, 2017 The Evolution of Engineering Materials Abstract This paper describes the development of an upper level engineering elective entitled “The Evolution of Engineering Materials.” The course considers how the discovery of new materials and the ability of process materials in new ways has influenced the course of history, shaping both human societies and their surrounding environments, from the Stone Age to the Modern Era. Students become familiar with a variety of still-relevant technical content through the consideration of historical activity, from smelting and coking to polymerization reactions and cross linking. The course addresses a variety of ABET outcomes while also supporting the development of global competency through an increased appreciation of world history. Although this course was developed for and taught in the context of a three-week study abroad trip to Europe, the engaging and accessible nature of the content could also make it valuable as a service course for non-engineering majors. -

The site is located in the north-eastern part of the present-day Romania occupying a small plateau situated in a hilly region. In order to evaluate the raw materials and the firing process we have used optical microscopy (OM), X-ray powder diffraction (XRPD) and magnetic measurements. Further on, the XRPD data were statistically treated using hierarchical cluster analysis (HCA) taking into account position and peak intensity, the Euclidian distance as metric and the average linkage method as a linkage basis for gaining a more refined estimation of the mineralogical transformations induced by the firing process and for defining homogenous group of samples. -

Transformative Copper Metallurgy in Chalcolithic Cyprus: a Reappraisal Bleda S
Antiquity 2021 Vol. 95 (381): 670–685 https://doi.org/10.15184/aqy.2020.171 Research Article Transformative copper metallurgy in Chalcolithic Cyprus: a reappraisal Bleda S. Düring1,*, Sarah De Ceuster2, Patrick Degryse1,2 & Vasiliki Kassianidou3 1 Faculty of Archaeology, Leiden University, the Netherlands 2 Earth and Environmental Sciences, KU Leuven, Belgium 3 Archaeological Research Unit, Department of History and Archaeology, University of Cyprus, Cyprus * Author for correspondence: ✉ [email protected] The extraction and smelting of the rich copper ore deposits of Cyprus and the manufacture of copper objects on the island are thought to have begun dur- ing the Philia phase (c. 2400–2200 BC). Here, the authors present the results of lead isotope analysis undertaken on Late Chalcolithic (2900–2400 BC) metal objects from the site of Chlorakas-Palloures. The results facilitate a reassessment of the timing of the start of transformative copper technologies on Cyprus and the re-evaluation of contemporaneous copper artefacts from Jordan and Crete previously suggested to have been consistent with Cypriot ores. They conclude that there is no compelling evi- dence for transformative metallurgy in Chalcolithic Cyprus. Keywords: Cyprus, Chalcolithic, Philia phase, archaeometallurgy, copper, lead isotope analysis Introduction Cyprus was a major producer of copper in antiquity, and, as a consequence, the metal and the island toponym (from the Greek ‘Kúpros’) became synonymous (Kassianidou 2014). The question of when and how copper production and metallurgy started on the island, however, has proven difficult to answer. The earliest references to Cypriot copper exports date to the nineteenth to seventeenth centuries BC, occurring in cuneiform texts from Mari and Alalakh —both in the Northern Levant—and from Babylonia (Muhly 1972; Knapp 1996). -
The Metallurgy of Some Carat Gold Jewellery Alloys
The Metallurgy of Some Carat Gold Jewellery Alloys PART I — COLOURED GOLD ALLOYS Allen S. McDonald and George H. Sistare Handy & Harman, Fairfield, Connecticut, U.S.A. The classification of gold alloys in terms of caratage and colour provides no guidance as to the properties and working characteristics of the many carat gold alloys used in jewellery fabrication. Logical relationships do exist, however, between the composition, metallurgical structure and properties of such alloys, and these emerge from a study of the phase diagrams of the alloy systems involved. Part I of this review deals with coloured gold alloys. Part II will discuss their nickel containing counter- parts and will appear in the next issue of Gold Bulletin. Most carat gold for jewellery falls into one or other Three quasi-binary vertical sections of the ternary of two major categories, the coloured gold alloys diagram at constant gold contents characteristic of based on the gold-silver-copper or the gold-silver- jewellery alloys (10, 14 and 18 carat) are schematical- copper-zinc system and the white gold alloys. ly represented in Figure 4 where the parameter used Although many coloured gold alloys contain zinc on the abscissa is defined as: (from less than 1 to about 15 weight per cent), it is Ag wt.% valid to introduce this group in terms of the gold- Ag' = x 100 (per cent) silver-copper ternary system, from which all of the Ag wt.°Io + Cu wt.% alloys inherit certain fundamental metallurgical characteristics.

751 Depending on 14C Data
RADIOCARBON, Vol 51, Nr 2, 2009, p 751–770 © 2009 by the Arizona Board of Regents on behalf of the University of Arizona DEPENDING ON 14C DATA: CHRONOLOGICAL FRAMEWORKS IN THE NEOLITHIC AND CHALCOLITHIC OF SOUTHEASTERN EUROPE Agathe Reingruber Eurasia-Department of the German Archaeological Institute, Berlin. Corresponding author. Email: [email protected]. Laurens Thissen Thissen Archaeological Ceramics Bureau, Amsterdam. Email: [email protected]. ABSTRACT. With the introduction of the radiocarbon method in 1949 and the calibration curve constantly improving since 1965, but especially due to the development of the more accurate accelerator mass spectrometry (AMS) dating some 30 yr ago, the application of the 14C method in prehistory revolutionized traditional chronological frameworks. Theories and mod- els are adjusted to new 14C sequences, and such sequences even lead to the creation of new theories and models. In our con- tribution, we refer to 2 major issues that are still heavily debated, although their first absolute dating occurred some decades ago: 1) the transition from the Mesolithic to the Early Neolithic in the eastern and western Aegean. Very high 14C data for the beginning of the Neolithic in Greece around 7000 BC fueled debates around the Preceramic period in Thessaly (Argissa- Magoula, Sesklo) and the Early Neolithic in Macedonia (Nea Nikomedeia). A reinterpretation of these data shows that the Neolithic in Greece did not start prior to 6400/6300 BC; 2) the beginning and the end of the Chalcolithic period in SE Europe. Shifting from relative chronologies dating the Chalcolithic to the 3rd millennium BC to an absolute chronology assigning the Kodžadermen-Gumelni˛a-Karanovo VI cultural complex to the 5th millennium BC, the exact beginning and the end of the period are still under research. -
