This study concerns glazed objects from two major centres in Silesia: Wrocław and Opole. All the glazed items from layers dated from the late 10th to the first half of the 13th century are appraised, i.e. ceramic and stone Easter eggs, knobbed rattles, ‘stars’ and pottery. Each category of artefacts is appraised separately as they differ from each other in terms of the production technique and presumably their provenance. Therefore, the locations of the workshops that produced these items is considered. Based on the collections from Wrocław and Opole, a different frequency of individual glazed items is observed, which is related to their specific distribution and most likely the different role of both centres. A separate issue is determining the value and social function of the glazed vessels, Easter eggs and rattles. In contrast, less emphasis is placed on their symbolic function, as this issue has been widely discussed by other researchers.
The temporary lowering of the water level in Dalešice Reservoir for maintenance in the autumn of 2021 created an opportunity to conduct an archaeological investigation of the Kramolín hillfort – a site permanently flooded since the 1970s. A small group of archaeologists reached the shore of Kramolín island by boat and performed the survey with metal detectors and GPS hand held devices. This survey produced a large collection of lithic artefacts, pottery sherds, and isolated metal artefacts from different prehistoric periods (including the Neolithic, Eneolithic, Bronze Age, Iron Age, Roman period and Early Middle Ages), which had already been identified during previous excavations. However, although the site was illegally surveyed with metal detectors earlier, several important artefacts were still found. In addition, the current state of the overlying sediment and its erosion was documented. The survey showed that the site is not yet exhausted and repeated survey in the case of the lowered water level can again provide more important information about this site.
