W kwestii techniki wykonania i szkliwienia wczesnośredniowiecznych pisanek-grzechotek ze Śląska

The article concerns early medieval egg-shaped rattles from the area of Silesia. First of all, the issue of how they were made and glazed is studied. The issues of the origin of these products and their role in the culture of ancient societies, as problems repeatedly raised by other researchers, is treated marginally. Macro- and microscopic observations, experimental studies, as well as the results of analyses of the chemical composition of glazes and petrographic tests of ceramic bodies were used to study the technology of making eggs-shaped -rattles. On their basis, the probable process of their formation and glazing was reconstructed. While the making of the ceramic base did not require extraordinary skills, the glazing and decoration of the rattles took place in several stages, requiring knowledge of advanced pottery techniques. For their decoration, a specific category of glaze was used, namely high-lead non alkali glass.
