The Decorated Ceramic Sherds, Plain Rim Sherds, and Clay Pipe Sherds from the Stallings Ranch Site (41LR297), Lamar County, Texas

Excavations at the Gene and Ruth Ann Stallings Ranch site (41LR297) during the 2005 and 2006 Texas Archeological Society Field Schools, as well as 2004 excavations by the Valley of the Caddo Archeological Society, recovered an interesting assemblage of prehistoric ceramics. In this article, I analyze the 88 decorated sherds, the 99 plain rims, and the 67 clay pipe sherds found during that work. In addition to characterizing the assemblage of vessel sherds and pipes in terms of decorative style and various technological attributes (i.e., temper and paste, firing conditions, surface treatment, etc.), I am also concerned with establishing the temporal and cultural affiliation of the recovered ceramics, particularly with respect to determining whether the ceramics found at the Stallings site are primarily from a Fourche Maline Woodland period occupation or a later, post-A.D. 800 Caddo ancestral occupation.

Provenance Study of Prehistoric Ceramics from Sicily: A Comparative Study between pXRF and XRF

The 1964 archaeological exploration of the Ognina islet near Syracuse, Sicily, has provided evidence suggesting a long-term prehistoric occupation from the Neolithic to the Middle Bronze Age. Maltese style ceramics were found in Early and Middle Bronze Age layers. A small group of imports belonging to the Thermi Ware culture was found in connection with the local Castelluccian Ware (EBA), and Maltese style Borġ in-Nadur wares were recovered with local Thapsos ceramics (MBA). During fieldwork in 2012, large amounts of ceramics were recovered including new examples of Thermi and Borġ in-Nadur wares as well as large amounts of Castelluccian and Thapsos pottery. In order to ascertain whether the Maltese type pottery was imported from Malta, a program of archaeometric analyses was established. Diagnostic samples belonging to both Maltese-like and Sicilian pottery classes were analyzed with destructive thin sectioning and X-ray fluorescence spectrometry (XRF) and subsequently analyzed with non-destructive portable X-ray fluorescence spectrometry (pXRF) together with a sample of Sicilian clay taken from a clay source close to the islet. The analyses demonstrated that the two Thermi Ware samples were locally produced and three out of four Borġ in-Nadur pieces had a Maltese provenance while one of the four being produced in Sicily.

Ageing of low-firing prehistoric ceramics in hydrothermal conditions

Remains of a prehistoric ceramic object, a moon-shaped idol from the Bronze Age found in archaeological site Zdiby near Prague in the Czech Republic, were studied especially in terms of the firing temperature. Archaeological ceramics was usually fired at temperatures below 1000?C. It contained unstable non-crystalline products, residua after calcination of clay components of a ceramic material. These products as metakaolinite can undergo a reverse rehydration to a structure close to kaolinite. The aim of this work was to prove whether the identified kaolinite in archaeological ceramics is a product of rehydration. The model compound containing high amount of kaolinite was prepared in order to follow its changes during calcination and hydrothermal treatment. Archaeological ceramics and the model compound were treated by hydrothermal ageing and studied by XRF, XRD and IR analyses. It was proved that the presence of kaolinite in the border-parts of the archaeological object was not a product of rehydration, but that it originated from the raw materials.

New 14C Dates of Neolithic and Early Metal Period Ceramics in Lithuania

Twenty-three samples of charred food remains, charcoal, burned animals, and human bones from 14 Lithuanian prehistoric sites were dated by radiocarbon as part of a dating project oriented towards renewing the prehistoric ceramics chronology. The new dates modified the dating of ceramic styles by hundreds to a thousand years. Three Textile Ware sherds were dated to 4230–2920 cal BC—the oldest known dates of Textile Ware pottery in the East Baltic. The organic-tempered pointed-bottomed Narva and Combed-like Wares were dated to 3970–3370 cal BC, while Bay Coast Ware (Haffküstenkultur, Rzucewo), including vessels decorated with cord impressions, were dated to 3940–3540 cal BC, i.e. to a period well preceding the Corded Ware/Battle Axe horizon in Europe. Three dates of Globular Amphorae Ware placed the phenomenon directly beyond the Bay Coast chronology, i.e. in 3450–2920 cal BC. Chamotte-tempered Corded Ware from SE Lithuania was dated to 2840–2570 cal BC. The first absolute dating of coarse ware of the Žalioji type pointed to a period of 760–515 cal BC instead of the previously assumed 2nd millennium cal BC. Cremated human bones from urns found at Paveisininkai, Kernavė, and Naudvaris cemeteries were dated to 790–380 cal BC. Accelerator mass spectrometry (AMS) dates obtained from charred food remains should be treated with a certain caution due to a possible freshwater reservoir effect that has not yet been examined in Lithuania.
