Third-party-funded project

Late Medieval production of glass

Project management at the University of Würzburg:

Participating scientists:

For a long time, the investigation of the Late Medieval glass production north of the Alps was restricted to the description, classification and dating of glass artefacts recovered from various excavations in cities or monasteries. Only in part these artefacts were chemically analyzed. During the last few years, however, archaeologists aimed more and more to the excavation of the locations of glass production, the glassworks themselves. Inbetween, several glassworks have been recovered in Germany. The aim of this project is to analyze all the archaeological material connected with ancient glass production. This includes the relics of production (which kind of glass was produced?), the melt crucibles (which clay was used? Did the glassmakers get the clay from a central deposit or did they take clay from local deposits? What was the thermal stability of the clay?), the material of the furnace building and furnace floor (local material? Thermal stability? Temperature reached?). Until now, the following glassworks were included into the investigations: Schönbuch near Tübingen, Nassachtal near Göppingen and Glashütten in the Taunus region. One important result was the identification of glassfritte as a precursor product of the final glass melt.
