Abstract
This interdisciplinary contribution presents three fragments of stained glass which were found in a secondary context at Devín Castle in 1975. They show figural motifs and letters, probably painted with a silver glaze.
The archaeometric analysis confirmed that it was of Na2O-CaO-Al2O3-SiO2 decolourized with manganese, and the broken edges show that it was a panel from a stained glass window. Following analytical comparative methods in connection with the archaeometric findings about soda-lime glass in early medieval Central Europe and based on analogies from Uherské Hradiště-Sady and Zalavár, they can be dated into the 9th century.
The glass from the stained glass window in Devín is probably of local origin, in the nearby Devínská Kobyla soda-lime glass was melted in a 30-l melting pot.
