“…Traces of hematite can cause a vivid orange colour of the pottery sherds, which implies an oxidizing firing atmosphere, whereas samples do not contain hematite suggest a low firing temperature (Kramar et al, 2012). The presence of magnetite revels that it was formed under reducing conditions (Sciau, 2016). Data reveals that (1) the crystalline phases range from 56.40 to 69.70% and the amorphous phases range from 30.30 to 43.60% and (2) the scarce occurrence of clay minerals (kaolinite) in the analyzed pottery sherds.…”

A set of selected fragments of pre-Hispanic pottery sherds that were excavated from the Mesa de Los Santos region's archaeological site (Colombia) were investigated by different analytical techniques and principal component and hierarchical cluster analyses. This study is very useful to understand more about the raw materials (and provenance) for ancient pottery production and their manufacturing technology. In addition to establish stratigraphic and anthropological relationships, the pottery sherds were analyzed to determine their mineralogical and chemical composition, as well as their structural characteristics using X-ray powder diffraction, wavelength dispersive X-ray fluorescence, scanning electron microscopy, and attenuated total reflectance Fourier transform infrared spectroscopy. The results indicated that the pre-Hispanic pottery sherds were manufactured using poor carbonates and iron oxide-bearing clays with no significant changes in the technology of manufacture, firing the pastes at the proper temperatures or selecting and processing the raw materials to fulfill their use. The manufacture of pre-Hispanic pottery was probably carried out using local raw materials, compatible with the regional geological context, and the archaeometric study reveals that the pre-Hispanic cultures who lived in this region hardly had access to trade of raw materials.

Mineralogical characterization of pre-hispanic pottery at the Mesa de Los Santos region, Colombia

et al. 2019

The application of mineralogy in archeology has been growing in interest in particular in relation to establishing the origin of the clays used in the elaboration of ancient ceramic artifacts. The mineralogy did not show a clear relationship with the colors expressed by the pottery system defined by the archaeologists; that is, independent of the color of the slip, each group has the same mineralogical components. Fourteen Pre-Hispanic pottery sherds from the Mesa de Los Santos region (Colombia) were selected for mineralogical characterization by X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The objective of the work was to contribute to the knowledge of the production technology and elucidate a possible regional origin of these ceramics. The observed mineralogical phases were plagiocalse, quartz, potassium fledspar, clay minerals, micas, carbonate minerals, and iron oxides. Firing temperatures are in the ranges 600-800°C for almost all the analyzed samples.

Analyzing the Heterogeneous Hierarchy of Cultural Heritage Materials: Analytical Imaging

Objects of cultural heritage significance are created using a wide variety of materials, or mixtures of materials, and often exhibit heterogeneity on multiple length scales. The effective study of these complex constructions thus requires the use of a suite of complementary analytical technologies. Moreover, because of the importance and irreplaceability of most cultural heritage objects, researchers favor analytical techniques that can be employed noninvasively, i.e., without having to remove any material for analysis. As such, analytical imaging has emerged as an important approach for the study of cultural heritage. Imaging technologies commonly employed, from the macroscale through the micro- to nanoscale, are discussed with respect to how the information obtained helps us understand artists' materials and methods, the cultures in which the objects were created, how the objects may have changed over time, and importantly, how we may develop strategies for their preservation.
