En este estudio sobre la organización espacial de la producción cerámica en Pénjamo y Abasolo (Guanajuato) se identifican los implementos básicos asociados a una tecnología de manufactura en moldes. Además, se documenta cómo los alfareros seleccionan y utilizan las materias primas en la producción de ollas para contener agua. A partir de un análisis mineralógico de los materiales se discute cómo el comportamiento del alfarero afecta la composición final de las ollas. Además, los resultados petrográficos son comparados con la composición de tiestos de ollas provenientes del sitio arqueológico Barajas, fechados en el periodo epiclásico. Finalmente se presentan algunas implicaciones arqueológicas derivadas del estudio de la producción actual.Abstract: The study of the spatial organization of ceramic production at Penjamo and Abasolo (Guanajuato) identifies the basic implements related with a mold manufacture technology. It documents how potters select and use raw materials in the production of water jars. Mineralogical analysis are used to discuss how the potter behavior affects the final composition of the ceramic jars. Also the petrographic results are compared with the composition of sherds collected from Barajas archaeological site, all dated to the Epiclasic period. Finally it presents some archaeological implications derived from the study of the actual ceramic production.Résumé : Dans cette étude de l’organisation spatiale de la production céramique à Pénjamo et à Abasolo (Guanajuato), nous présentons les outils de base associés à une technologie de manufacture au moule. Nous expliquons également comment les potiers choisissent et utilisent les matières premières afin de produire des jarres destinée à contenir de l’eau. Une analyse minéralogique des matériaux donne lieu à un débat concernant les effets qu’entraîne le comportement de l’artisan sur la composition finale des jarres. Les résultats de l’analyse pétrographique sont comparés à la composition des tessons de jarres provenant du site archéologique épiclassique de Barajas. Enfin, sont présentées quelques implications archéologiques découlant de l’étude de la production actuelle.

Can Sadurní’s cave, located in Begues (NE Iberian Peninsula), in the Baix Llobregat region, is an archaeological site with a wide stratigraphic sequence covering from the Epipaleolithic hunter-gatherers societies at the beginning of the Holocene to Roman times. During the excavations of the last years a large number of different raw materials used for the manufacture of axes have been recovered.The present study is focused on the Neolithic sequence. 31 axes and adzes have been characterised petrographically with the aid of a binocular microscope and transmission microscope. A great variety of rocks constitute the raw materials of these stone tools, ranging from contact and regional metamorphic rocks to plutonic and porphyric igneous rocks. The formers are the most abundant (up to 78%) and include hornfels, spotted phyllites, marbles, quartzites, slates and phyllites. The igneous rocks consist of granodiorite, porphyry and aplites. Such a great assemblage of rocks matches in a geological context representative of a plutonic intrusion and its metamorphic contact aureole. Following that scenario we suggest that the most likely source area for all these materials occur at the Collserola hills, at 27 km far to the east from the cave, at the other side of the Llobregat River, where an Hercynian granodiorite and related igneous rocks intruding Ordovician metasedimentary materials are presented.

Archaeological Excavations

Archaeological excavations at the Gault Archaeological Site (41BL323) have revealed an almost complete stratigraphic record of the prehistoric occupation of Central Texas (Collins 2002, 2004). Furthermore, ages obtained from Area 15 of the site confirms good stratigraphic agreement between the diagnostic artifacts, cultural horizons, and stratigraphic units (Rodrigues, et al. 2016; Williams, et al. 2018). This includes some of the earliest evidence for a projectile point technology in North America (Williams, et al. 2018). Like many areas in Central Texas, the combination of water, raw materials, and its position along the Balcones Escarpment provided abundant resources essential to survival. The Gault Archaeological Site has a long history. The site takes its name from a previous landowner, Henry Gault, and the first scientific excavations were conducted there in 1929 under the supervision of J. E. Pearce. In 1990, David Olmstead reported a unique find; an Alibates Clovis point sandwiched between two limestone plaques with engraved geometric designs. This led to a site visit by Dr. Tom Hester and Dr. Michael Collins. This finding was followed in 1997 by the discovery of an extremely fragile mandible of a juvenile mammoth by the Lindsey family. These discoveries prompted the recent archaeological excavations at the site, which began in 1999 and lasted until 2002. As many archaeologists will attest, the most interesting findings came at the very end of the 2002 field season, when archaeologist Sam Gardner exposed cultural material stratigraphically below Clovis in a small test unit. This led to negotiations between Michael Collins and the Lindsey family that resulted in the purchase of the property by Dr. Collins and its donation to the Archaeological Conservancy. Between 2007-2014, Area 15 was excavated to expose the cultural materials below. With the cessation of excavations in 2014, research focuses on reporting these findings and how this early archaeological assemblage in Central Texas is redefining the search for the earliest human occupants of the Americas. The front cover of this issue of the Journal of Texas Archeology and History highlights two specific chronological periods in Texas. Firstly, in each corner you will find interactive 3D scans of four Clovis points that have been recovered from the site (Seldon et al. 2018). In between these, you will find and array of Archaic projectile points that have been recovered from the various excavations conducted between 1999-2002 and 2007-2014. This includes Early Archaic points such as the Hoxie and Martindale; Middle Archaic points including, Kinney and Nolan; and Late Archaic points including Pedernales, Marshall, and Bulverde. Clovis artifacts including, projectile points, blade cores, and diagnostic debitage have been recovered from a total of 9 excavation areas. We will expand on these covers in the future to cover specific research projects currently being undertaken by the Gault School of Archaeological Research staff. The Gault School of Archaeological Research is a non-profit, 501(C)3 charitable organization dedicated to innovative, interdisciplinary research archaeology and education focusing on the earliest peoples in the western hemisphere and their cultural antecedents.

The paper presents the results of analyzing the prospects of using clay raw materials in a composition with metallurgical slags for the production of ceramic products. The results of the analysis of the chemical and mineralogical properties of clay from the Khalilovsky deposit in the Orenburg region and nickel slags from the dumps of the South Ural Nickel Combine are presented. The studies were carried out using X-ray fluorescence and differential thermal analysis methods. The article presents the performed X-ray and derivatograms of slag and clay and the features of the experimental types of raw materials revealed during their analysis. The connection between the chemical and mineralogical compositions of the experimental clay and slags on the technological properties of finished ceramic products has been theoretically established. The use of XRF and DTA to study the characteristics of plastic and non-plastic raw materials made it possible at the first stages of the experiment to reject materials that were unsatisfactory in properties for the production of ceramic products, which contributes to the optimization of experiments, rational consumption of costs of newly mined clay raw materials.

Abstract This study examines small-scale household ceramic production at the site of Xaltocan, Mexico, to understand the organization of household ceramic production prior to the development of the Aztec Empire. We examine utilitarian vessels and serving wares from an Early Postclassic (a.d. 900–1200) domestic context using neutron activation analysis (NAA). We also examine archaeological evidence for ceramic manufacture. The NAA data reveal that similar raw materials and paste recipes were used for both utilitarian and decorated wares, suggesting that households produced both plain and decorated pottery. We conclude that ceramic production was an intermittent activity that took place alongside other crafts and agriculture. By looking at ceramics within their contexts of use and production, we consider the practices and choices made by individual social units, which is crucial to interpreting broader Early Postclassic economic systems and the ways in which commoners influenced these systems.

Abstract This paper outlines the main theoretical approaches to the role of transport in spatial organization and investigates possible new extensions at a theoretical and practical level, focusing on the analysis of transport cost. Beginning from the traditional theories of spatial distribution and the location of economic activities under transport cost, the analysis focuses on the related approaches of the new economic geography, which are based on the assumptions of the known “iceberg cost”. After that, through the presentation of indicative empirical studies, the paper attempts to clarify new issues that should be taken into account in the relevant theoretical considerations as well as in the political practice. Thus, factors such as the change of production structure in the modern economies with the production of more quality products, lower mass, and higher relative value and intangible goods, in combination with the improved transport technology, have contributed to a continuous reduction of the transport cost of raw materials and productive goods over the years. These developments along with the growing importance of cost of moving people should be taken into account in the new theoretical interrogations and the political practice of regional and urban development

This work focused on the study of decorated pottery dated back to the 16th century from the Roman archaeological site of Villa dei Quintili, a monumental complex located in the south-eastern part of Rome (Italy). A minero-petrographic and geochemical study was undertaken to analyse five archaeological samples in order to define textural features and raw materials used for their production, along with the chemical and physical composition of the superficial decorative glazed coatings. For this purpose, different analytical methods were used, such as polarising optical microscope (POM), X-ray diffraction (XRD), micro-Raman spectroscopy, X-Ray fluorescence (XRF), and electron microprobe analysis coupled with energy dispersive spectrometry (EMPA-EDS). The results of such a multidisciplinary approach allowed us to achieve important results crucial to recognise the shards as majolica of the Renaissance period, improving knowledge about manufacturing processes of these renowned painted ceramic artefacts.

The present work concerns the study of geological raw materials obtained from an excavation site located in Serra da Cabreira (NW Portugal). The majority of the artifacts are made in quartz varieties (with minor occurrences of flint). Milky quartz is dominant, being similar to diverse occurrences of quartz veins in the immediate neighborhood. There are diverse other quartz varieties, indicating the possibility of locations farther away from the shelter. The study of geological raw materials can be seen as an important source of archaeological information, illustrating the evolution of past relationships between humans and geological resources, and also providing relevant information for the present and future, considering namely the extremely low environmental impact of the processing of raw materials.

This paper reports the findings of an archaeometric study performed on 14 architectural earthenwares from the archaeological site of S. Omobono, located in the historic center of Rome (Italy). The archaeological site, accidentally discovered in 1937, includes the remains of a sacred area previously occupied by two temples, one of which was converted into the church of S. Omobono, in 1575. The samples, dated between the 7th and the 6th century BC, belong to different sectors of the site. Their petrographic, mineralogical and geochemical characterization was performed by optical microscopy (OM), X-ray powder diffraction (XRPD), X-ray fluorescence (XRF), electron probe micro-analysis (EPMA), and Raman spectroscopy (RS). The compositional data obtained were also subjected to the principal component analysis (PCA) in order to highlight similarities and differences among the samples. By combining geochemical and petrographic data, we were able to identify several different fabrics. Furthermore, the study provided valuable information on the firing temperatures of some samples and the provenance of the raw materials, by analyzing the chemical composition of clinopyroxenes present as non-plastic inclusions.
