Yes / While stone vessels were sometimes included in ancient Egyptian elite burials of the New Kingdom, presumed to have been used as cosmetic vessels, we still know little about the contents they held. The situation is even more vague for jars in Nubia, where they occur less frequently. We report here on a study of a travertine jar from the Cemetery of el-Dakka in Lower Nubia, and the scientific analysis of its contents, comparing the jar with other known examples.

Ceramics are more than merely the most common artifact type in the archaeological record of most parts of the world. While they have long served as chronological markers, they also provide insights into the daily lives of the people who made, used, and exchanged them. In this dissertation I present a study of three ceramic assemblages from the Tlajinga district of Classic period (AD 100 – 650) Teotihuacan, Mexico. I focus on consumption practices and temporal changes by evaluating the ceramics recovered through excavations at two multifamily apartment compounds and a neighborhood center. I first compare the assemblages from each area, then assess how they changed over time. Given that the composition of ceramic assemblages results from different use and depositional practices, one of the main issues addressed is the importance of contextual information for their analysis. Thus, I analyzed primary deposits in relation to stratigraphic data; this way, I provide a basis for the relative dating of the three sites and the refinement of the existing ceramic chronology. Absolute dates came from the largest number of radiocarbon dates analyzed thus far for a residential sector at Teotihuacan. I also employed three analytical techniques: chemical residue analysis to identify vessel contents, and petrographic and neutron activation analysis to identify clay sources. Even though Tlajinga’s inhabitants used most of their utilitarian wares for cooking, storing, and serving purposes, the chemical residue analysis suggests other uses and possible reuses that challenge what we believed was the sole function of certain ceramic vessels. Petrographic and compositional studies group locally manufactured ceramics and distinguish imports into clear provenance clusters, allowing us to better understand interregional exchange and ceramic consumption in Tlajinga. Results illustrate that there is a uniformity in the ceramic assemblages of the two domestic areas but they differ significantly from those recovered from the neighborhood center, of a presumed more public function. This study uses a multidisciplinary approach to demonstrate a clear difference between the private and the public spheres at Tlajinga. This has important implications for understanding urban lifeways and the organization of domestic and neighborhood space at Teotihuacan. / 2025-07-01T00:00:00Z

No / The concept that invisible molecular traces may remain in grave deposits, the often discarded ‘dirt’ from substantial mortuary containers, is not widely appreciated. Organic residue analysis of samples from Late Roman (2nd–4th c. AD) burials in Britain has revealed their potential to retain diagnostic biomarkers. Alongside the analysis of visible residues from similar continental burials, these results confirm that resinous substances were employed in the treatment of the dead throughout the Roman Empire. Deposited in close proximity to the body, they masked the reality of decay, signified the status of the deceased and promoted memorialisation. These findings, in conjunction with the sampling approach and methodology detailed here, have important implications for future mortuary research in the late antique period and beyond. / R. C.

The use of mortar and pestles has long been associated with acorn processing in California. Based on ethnographic and archaeological evidence, groundstone was used to process a multitude of resources, including small mammals. Twenty groundstone artifacts recovered from the Rock Camp Site in the San Bernardino Mountains were analyzed for protein residues using the crossover immunological electrophoresis (CIEP) method. Using previously obtained data from the Summit Valley, a comparative analysis was done to determine if processing small mammals on groundstone was a common occurrence throughout the San Bernardino Mountain region.

This thesis is a pilot study, designed to test and develop methods suitable for the study of Scandinavian flint spearhead functionality. The functionality of projectile and lithic point armament has not been studied for almost 30 years in Scandinavia. Meanwhile, methods used to analyse lithic projectiles have developed considerably. However, few of these methods are precise enough to be used in conjunction with Scandinavian stone technological analyses that emphasize the societal aspect of lithic points. Consequently, two methods were chosen that could provide data for Scandinavian research issues: 3D-scanning/continuum mechanical simulations and organic residue analysis. The methods were tested on 6 experimental spearheads. The continuum mechanical simulation generated both visual and numerical data that could be used to create precise functional-morphological descriptions. The data could also potentially be used for projectile point classification. The organic residue analysis revealed promising results for the use of an artefact and activity specific analysis, with a sequential extraction protocol. In unison, the results from both analyses could be used to reveal how spearheads were functionally designed and used in Stone Age Scandinavia, even though there are methodological and technological issues that need solving.

A number of charred surface residues, adhering to ceramic containers, were obtained from various coastal and inland sites in north-west Europe dating from the sixth to the fourth millennium cal bc. In order to investigate the use of these vessels and in particular to identify any marine products, the residues were subjected to carbon and nitrogen stable isotope analysis. Variation in carbon isotope ratios between different samples indicated that some vessels may have been used to process marine products. This analysis was corroborated by specific identification of aquatic products following structural and isotopic characterization of lipids extracted from selected samples.

Despite the variety of successful reports of the preservation, recovery, and identification of archaeological proteins in general, there are few positive reports regarding mass spectrometry-based identification of ceramic-bound proteins. In large part, this shortage is due to the lack of consideration for the unique taphonomic histories of such residues and, in general, methods development. Further, because negative results are rarely published, there is no baseline to which results can be compared. This paper attempts to address these challenges via a multi-pronged approach that uses mass spectrometry and complementary approaches to evaluate ceramic-bound protein preservation in both controlled, actualistic experiments, and in archaeological artifacts. By comparing the results obtained from protein-spiked, experimentally-aged ceramic to those obtained from both faunal and ceramic archaeological materials, an enhanced perspective on protein preservation and subsequent recovery and identification is revealed. This perspective, focusing on taphonomy, reveals why negative results may be the norm for ceramic artifacts when non-targeted methods are employed, and provides insight into how further method development may improve the likelihood of obtaining positive results.

This study aims to contribute to the field of paleoethnobotany in Florida archaeology by presenting a novel approach to chemical residue analysis using UV-vis spectroscopy. The project's main goals are to develop a spectroscopic method for analyzing ceramics to identify phytochemical residues and present the findings of chemical analysis applied to ceramics from the Cape Canaveral archaeological mitigation project (CCAMP). The study focuses on two sites, the Penny site (8BR158) and Burns site (8BR85) in Florida's Indian River region. While organic residue analysis (ORA) has been applied to various materials and regions, limited research ORA on has been conducted within Florida archaeology. This study presents this approach in a simple and comprehensive manner so that it may be replicated by archaeologists who may be novice in in photospectroscopic methods. The presence of caffeine in the context of Malabar Period sites can enhance our understanding of the Ais people's foodways and cultural practices in Cape Canaveral by showing the ritualistic and common day use of Black Drink made from Ilex vomitoria. By developing this specific analytical method and applying it to the pottery from CCAMP, the study has shed light on the past use of ceramics, as well as the plant resources utilized by the people of prehistoric Florida.

Starch grain residue analysis was conducted on 18 artifacts collected in 2021 from the archaeological site 8BR158 on the Cape Canaveral Space Force Station. This paleoethnobotanical analysis investigates plant use by the pre-historic inhabitants of the Central Coast of Florida where there is a lack of archaeobotanical research. The starches recovered from the archaeological artifacts were studied in order to identify plants used for culinary and/or medicinal purposes. Wild plants commonly found in Florida, such as acorn (Quercus), were identified in this study that were used for food resources. Domesticated plants such as maize and beans were also identified in this study, which was an unexpected finding. This research contributes information on the relationship between pre-historic plants and the pre-historic inhabitants of the Cape Canaveral area.
