Opis:
This paper presents the results of an expert study of several glass vessels from an early medieval castle at Ostrów Lednicki. They come from the so-called second church, a single-nave small building erected in the 1060s and destroyed in 1038 or 1039. In its ruins, a collection of high-grade artefacts was discovered, furnishings of the same temple, as well as fragments of glass and fragmentary preserved glass vessels. The three specimens, examined in the laboratory, were made of potassium glass, of the calcium-potassium variety, of the CaO-K2O-MgO-Al2O3-SiO2 type. Interpretation of the analytical results has led to a conclusion that all the vessels could come from a single workshop, attributed to Carolingian and Ottonian workshops in Imperial Germany. Another vessel, discovered in the eastern part of the stronghold and not associated with any of the sacred buildings, has an early date (6th to 9th century). It is believed to be a conical goblet of the Kempston type, made of sodium glass, of the mineral variety, of the Na2O-CaO-Al2O3-SiO2 type, from one of the many Western European workshops.

Opis:
The study presents 175 artefacts from the settlement center in Gniezno – beads and rings. The materials come from settlement levels from around the mid-10th to the 13th centuries. The latest chronological findings based on 14C dating have made it possible to refine the dating, especially of the early settlement levels of the stronghold, where the vast majority of glass artefacts come from. Threeba sic groups of beads have been distinguished based on the technique of their production – beads made of a drawing a tube, the technique of winding a glass strip, as well as casting and sintering. The results of 7 physico-chemical analyzes of the glass composition (performed with the X-Ray Fluorescence, XRF method) are presented. Physicochemical analyzes of the chemical composition of the tested beads made it possible to determine the technological group and the type of glass. An attempt was made to explain the origin of the starting material (glass) for jewelery. A comparative analysis made it possible to indicate in a general manner possible manufacturers and to outline the likely directions of the influx of these glass ornaments to Gniezno.
