Type X pottery, Morobe Province, Papua New Guinea: Petrography and possible Micronesian relationships

Type X is one of four Post-Lapita pottery styles reported from Huon Peninsula and the Siassi Islands of Papua New Guinea. Previous petrographic work was inconclusive about its likely area of origin but indicated a possible Huon Peninsula source. Renewed analysis of a larger sample supports this conclusion and confirms the use of grog temper. This kind of temper is otherwise not recorded in the New Guinea region, and its use in the production of Type X was probably culturally driven. Comparisons between Type X and grog-tempered pottery from Palau, Yap, and Pohnpei in Micronesia lead to the suggestion that Type X probably derived from an otherwise unrecorded contact between Huon Peninsula and Palau about 1000 years ago. The article reviews other evidence for interaction between the New Guinea-Bismarck Archipelago region and various parts of Micronesia and concludes that the proposed Type X connection with Palau is but one of several prehistoric contacts between different parts of the regions. Recognition of such contacts, which could have been unintentional and on a small scale, may contribute to explaining the complex ethnolinguistic situation of Huon Peninsula.

On the distribution and notation of the Etruscan sibilants

A mechanical rule proposed in 1997 by Massimo Pittau for the distribution of the Etruscan sibilant graphemes sigma and san is investigated and found wanting. The etymological distribution proposed by Helmut Rix is clearly superior, yet many scholars appear reluctant to embrace Rix's findings. It is suggested that this reluctance stems in part from the incompatibility of Rix's notation with the traditional system. Consequently a simple method of reconciling the two systems is Proposed and then demonstrated in exhibiting the data relevant to Pittau's rule.

Standardization in the Pre-Columbian Pottery from El Caño, Panama: Specialization, Productivity and Consumption

The pottery found in the burials of El Cano is uniform in style to these made in the coclesanos valleys between 700 and 1000 AD. The coefficient of variability of the different pottery forms, evidence diverse standardizations values for polychrome and non-polychrome ceramics. Moreover, data of funerary contexts from the Cano recently excavated, suggest that elite has controlled ceramic production. This control over the production of certain goods reveals that these were important in the support or proper operational of the chiefdoms in Panama and mark the phase of splendour of this culture.

Rehydroxylation Dating: Assessment for Archaeological Application

Investigations are carried out into the mass gain behaviour of fired clay ceramics following drying (130°C) and reheating (500°C), and the application of these mass gain properties to the dating of archaeological ceramics using a modified rehydroxylation dating (RHX) methodology, a component based approach. Gravimetric analysis is conducted using a temperature and humidity controlled glove box arrangement (featuring a top-loading balance) on eighteen samples of varied known ages and contexts; this occurs following transfer from environmentally controlled chambers where subsamples of these samples are aged at three temperatures (25°C, 35°C, 45°C) following drying and reheating. The sample set consists principally of post-medieval bricks, but also includes some post-medieval pottery as well as both Etruscan and Roman ceramics. A suite of techniques are applied to characterise these ceramics, including XRD, FTIR, p-XRF, thin-section petrography, BET analysis, TG-MS and permeametry.

La Rocca di Castiglione del Lago (PG) Campagna di scavo 2014

The archaeological study took into account a very important part of Castiglione del Lago urban unit, where the presence of stratification, probably from the Classical period, had been pointed out, on which military and religious units were over-lapped. More specifically, the area with a small church inside the arms courtyard of the castle, could have suggested the presence of archaeological realities,especially from the sporadic finding of Etruscan pottery. The archaeological investigation was first launched in the area of the small chapel, where at least two construction phases were highlighted, although with no appreciable result regarding Classical period phases. The excavation led to the discovery of underground structures, a number of Renaissance tombs placed around the church, and the identification of other structures related to military use over a cistern-well. At the end of the excavation, the structures were consolidated and protected before the backfilling; the materials recovered during the investigation have been registered at the Municipality of Castiglione del Lago, after bein examined by the Soprintendenza per i Beni Archeologi dell’Umbria and the Soprintendenza per i Beni Storico, Artistici ed Etnoantropologici dell’Umbria.

Technological characterization of molded islamic pottery from Iberian Peninsula

The thesis examines the technical aspects of unglazed molded ceramics from Mértola, in the context of Islamic archaeology of the Iberian Peninsula (Almohad period, end of 12th and the beginning of 13th century). Ceramics of the time period under discussion (12th – 13th century) are understudied, including in what concern to shaping and firing of ceramic vessels, the origin of raw materials used in ceramics and glazes, and decoration methods such as slip painting and/or colored glazes. Moreover, the use of archaeometry tools is rare. Along with providing a general picture of molded ceramic production in Mértola, this work provides a new dimension to the discipline of Islamic ceramic studies by the analytical tool used and demonstrating the importance of archaeological ceramics of the western peripheries to the understanding the production of ceramics and the transmission of knowledge and cultural traditions within the Islamic caliphate. The chemical and mineralogical characterization of 12th/13th century Almohad unglazed molded ware from Mértola was accomplished through multi – analytical approach combining SEM, Powder/uXRD and LA-ICP-MS methods. In this paper unglazed and glazed samples were analyzed but the attention was given to unglazed specimens, while the glazed samples were used for the comparison with the previous group in order to determine possible similarities or dissimilarities, thus providing enough data to discuss about technical aspects and potential provenance; Resumo: A tese debruça-se sobre os aspetos técnicos de cerâmica de molde não-vidrada de Mértola, no contexto da arqueologia islâmica da Península Ibérica (período Almóada, final de XII e início do século XIII). A cerâmica do período em discussão (séculos XII-XIII) é pouco estudada inclusive no que concerne ao fabrico e à cozedura, à de fonte de matérias-primas, na pasta ou nos esmaltes e aos métodos de decoração, como pintura, presença de engobes ou esmaltes. Além disso, o uso de ferramentas de Arqueometria é raro. Para fornecer uma visão geral da produção de cerâmica moldada em Mértola, este trabalho oferece uma nova dimensão para a disciplina de cerâmica islâmicas pelas ferramentas analíticas utilizadas. Demonstrando a importância da cerâmica arqueológica da periferia ocidental para a compreensão da produção cerâmica e a transmissão de conhecimentos e tradições culturais no califado islâmico. A caracterização mineralógica e química das cerâmicas de molde e não-vidrada, Almóada, dos séculos XII-XIII de Mértola foi realizada através de uma abordagem multi-analítica que combina métodos de SEM-EDS, uXRD e LA-ICP-MS. Neste trabalho, as cerâmicas vidradas e não-vidradas foram analisadas conjuntamente, dando mais atenção aos espécimes não vidrados. As amostras de cerâmicas vidradas foram utilizados para a comparação com o grupo anterior, a fim de determinar as possíveis semelhanças ou diferenças, proporcionando, assim, dados suficientes para discutir os aspetos técnicos e o potencial de proveniência das cerâmicas não vidradas

CT scanning in archaeology

In this chapter we will review the use of x-ray computed tomography (CT) scanning in the field of archaeology. The story will be told in roughly chronological order, starting with the first reported use of a CT scanner in the field of archaeology and then look at some some possibilities for the future. Since the introduction of the x-ray CT scanner in the 1970’s the quality of the images has steadily improved enabling the role of the CT scanner to expand into the field of archaeology. In the context of this chapter, archaeology will be deemed to include the study of ancient human remains and artefacts but exclude remains from pre-history, which normally comes under the heading of palaeontology. (It would perhaps be appropriate to note that CT scanners have been successfully applied in the study of fossils). CT scans have mostly been used to study mummies but have also been used to examine other archaeological artefacts such as clay tablets, scrolls, pottery, bronze statues and swords.

Upwave cities, creative cities : the case of London

The saddest book on cities I have read in a long time is The Lost City of Stoke-on-Trent by Matthew Rice (2010). Rice, who is married to the pottery owner Emma Bridgewater, charts the long decline of the potteries since the 1970s, when many brands closed local potteries to move overseas to Indonesia. There are now only a dozen or so potteries left in Stoke and many jobs that once were there have simply vanished. Yet at one time, Stoke was a place of great wealth creation, innovation and industriousness. The lesson is that once a local economy loses its dynamism, the place itself stagnates and may even die. Stoke is to the UK what Detroit is to the USA. Rice also shows that successive attempts at urban renewal have largely failed to make any impact in reversing Stoke’s declining fortunes. Economic stagnation and decline occurs in real places, leaving multiple economic, social and cultural problems in its wake. Over a period of years, local communities and residents gradually grow poorer, as wealth leaks away to other places.
