A contribution to the study of post-depositional alterations of pottery using TL dating analysis
On the Influence of Drying and Firing of Clay on the Formation of Trace Element Concentration Profiles Within Pottery
On experimentally fired briquettes made of five chemically and mineralogically different clays, trace element concentration profiles from the centre to the surface of the briquettes have been measured by Neutron Activation in order to examine if drying and firing of the clays lead to a mobilization and subsequent migration of single components within a sherd. Mineralogical changes during firing have been determined by X‐ray diffraction. Generally…
Neutron activation analysis of Hellenistic pottery from Boeotia, Greece
Pottery Wares from the Prehistoric Settlement at Ialysos (Trianda) in Rhodes
Among the vast amount of pottery yielded from the Late Bronze Age settlement of Ialysos (Trianda) on Rhodes, 233 samples have been selected for chemical analysis by means of Neutron Activation Analysis (NAA) at the Bonn Laboratory. Thus, a rather comprehensive new data-base for pottery assemblages from Rhodes and other related production centres has been provided. Further evidence has been also suggested for the local mechanisms of pottery produc…
Analcime Crystallization and Compositional Profiles—comparing Approaches to Detect Post‐depositional Alterations in Archaeological Pottery
The approaches of comparative studies and profile measurements, often used in order to detect post‐depositional alterations of ceramics, have been applied simultaneously to two sets of Roman pottery, both of which include altered individuals. As analytical techniques, Neutron Activation Analysis and X‐Ray Diffraction have been used. Both approaches lead to substantially different results. This shows that they detect different levels of alteration…
Implications of burial alterations on luminescence dating of archaeological ceramics
Clay paste mixtures identified by Neutron Activation Analysis in pottery of a Roman workshop in Bonn, Germany
Post‐Depositional Elemental Alterations in Pottery
From 38 sherds with ‘corroded’ surfaces, two samples per sherd were examined using Neutron Activation Analysis, one from the surface and one from the core of each sherd, in order to analyse post‐depositional alterations of minor and trace elements. The most striking effect was that a leaching of Ca could be found at the surface. Another group of elements that is severely affected are the alkali metals, with Cs and Rb showing the strongest changes…

Neutron Activation Analyses of ‘Falke‐Group’ Stoneware
Fragments of late medieval highly decorated Falke‐group stoneware have been found in excavations all over central and northern Europe. The distribution of the finds points to an origin in Saxony, but the exact centre of production is still unknown. Therefore, a set of samples has been analysed with Neutron Activation and the data compared with Saxon reference groups. The results point to production in a single workshop. The data can be clearly di…
The Petrography and Chemistry of Thin‐walled Ware From an Hellenistic– Roman Site at Segesta (Sicily)
Samples of Roman thin‐walled ware from Segesta (northwestern Sicily), dating back to the early Imperial period, were studied by optical microscopy (OM) and Neutron Activation Analysis (NAA). Up to now, this class of Roman fine tableware has only occasionally been evaluated archaeometrically. Nevertheless, numerous production centres are believed to have been simultaneously active in the western Mediterranean area. Petrographic and chemical data s…
