“…Methodologically, we evaluated the challenges and potentials of geochemical discrimination of grogtempered archaeological ceramics. Successful geochemical discrimination of ceramic fabrics using SEM-EDS has also been demonstrated previously and with grog-tempered fabrics (Holmqvist et al, 2014;Spataro, 2011;Zuluaga et al, 2011), yet a high-sensitivity method, such as PIXE, complements the SEM-EDS analysis by extending the elemental variety available for data interpretation and group assignments. The SEM-EDS and PIXE data sets show clear correlation in the data patterns (e.g., correlation coefficient R for SEM-EDS/PIXE measured CaO/Ca and FeO/Fe was 0.7 and 0.8, respectively, elements lighter than Ca were not measured with PIXE; see Fig.…”

The Neolithic Corded Ware Culture (CWC) complex spread across the Baltic Sea region ca. 2900/2800-2300/2000 BCE. Whether this cultural adaptation was driven by migration or diffusion remains widely debated. To gather evidence for contact and movement in the CWC material culture, grog-tempered CWC pots from 24 archaeological sites in southern Baltoscandia (Estonia and the southern regions of Finland and Sweden) were sampled for geochemical and micro-structural analyses. Scanning electron micro-scopy with energy dispersive spectrometry (SEM-EDS) and particle-induced X-ray emission (PIXE) were used for geochemical discrimination of the ceramic fabrics to identify regional CWC pottery-manufacturing traditions and ceramic exchange. Major and minor element concentrations in the ceramic body matrices of 163 individual vessels and grog temper (crushed pottery) present in the ceramic fabrics were measured by SEM-EDS. Furthermore, the high-sensitivity PIXE technique was applied for group confirmation. The combined pot and grog matrix data reveal eight geochemical clusters. At least five geochemical groups appeared to be associated with specific find locations and regional manufacturing traditions. The results indicated complex inter-site and cross-Baltic Sea pottery exchange patterns, which became more defined through the grog data, i.e., the previous generations of pots. The CWC pottery exhibited high technological standards at these latitudes, which, together with the identified exchange patterns and the existing evidence of mobility based on human remains elsewhere in the CWC complex, is indicative of the relocation of skilled potters, possibly through exogamy. An analytical protocol for the geochemical discrimination of grog-tempered pottery, and its challenges and possibilities, is presented. explore the life histories of individuals, and CWC cemeteries in Germany, for instance, have shown a high degree of individual mobility, especially for women (e.g. Sjögren et al., 2016). While these new analyses have provided an understanding of the general processes occurring in Europe at the time, the model is difficult to verify in Finland and Sweden due to the scarcity of well-preserved human CWC remains (Malmström et al., 2015). To reveal details about the regional and local processes that led to the establishment of the Corded Ware culture in southern Baltoscandia, we must combine the analysis of human remains with new ways of examining the material culture.

The Interaction Between a White Material Inside and Outside a Pottery Vessel From Eastern Ein-Shams, Egypt

This work aims to investigate a pottery vessel from eastern EIN-Shams, Egypt, lying in sandy soil from citizen lands, returning to the New Kingdom-Egypt. This pottery vessel was covered with white material from inside and outside. In terms of origin, this vessel is made of buff-colored clay; it has big pores, many cracks, and large missing areas filled with that material, with an uneven surface texture, that strongly bonds with the body pores, and shrinks away from the edges in some areas, in this way obscuring the original surface. In this respect, several physicochemical investigations in terms of chemical composition, physical properties, and nature of this white material were performed, to analyze the influence of it on the ancient pottery vessel. The analytical methods used in this research were USB digital microscopy, X-ray diffraction (XRD), scanning electron microscopy coupled with energy dispersive X-ray (SEM-EDX), and differential thermal analysis (DTA). The results of the USB digital microscopy showed the presence of gypsum crystals, large, flaked pottery surfaces, and quartz. SEM-EDX revealed the presence of organic fibers, chloride salts in a significant percentage, iron, and aluminum oxides. XRD investigation emphasizes the presence of gypsum and sodium chloride salts. DTA results revealed that the firing temperatures of the pottery vessel range between around 750-800°C.

“…SEM‐EDX, a non‐destructive method, determined the precise mineralogical elemental composition and information of the microstructure, grain size and surface treatment of archaeological pottery (Freestone and Middleton 1987; Palanivel and Meyvel 2010; Holmqvist et al . 2014; Kılıç et al . 2017), while XRD facilitates a detailed description of the fabric of the two vessels.…”

For the first time, residue‐analysis results of a red‐rim bowl discovered at Qubbet el‐Hawa in Aswan, Egypt, are discussed alongside the thermal characterization of unpublished pottery bowls of the Old and Middle Kingdoms from the same site. Scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX) and X‐ray diffraction (XRD) analysis were performed to provide fabric description of the bowls. The results show the presence of 4‐heptenoic and 4‐decenoic acids. The Old Kingdom bowl showed a firing temperature range of 800–850°C, while the Middle Kingdom example was fired to higher temperatures. This is a suggested explanation of the decrease in the use of red coating as a surface treatment after the Old Kingdom.
