Alberta Silvestri|Alessandra Marcante
The site of Nogara (province Verona, Italy) provides valuable insights into the complexities glass industry in mid-Medieval times, due to its timing, which ranges mainly between 10th and 11th centuries AD, great quantity findings, tableware. In present paper, combination archaeological, chemical textural data allows us identify production technologies a time-interval perceived be period technological transition for glass. particular, frequent occurrence recycled natron only few samples made with soda plant ash indicate that recycling earlier was common inland Northern Italy 10th–11th AD. addition, blue reticello decorations were obtained by mosaic tesserae, as shown much Co, Cu, Sn, Sb Pb presence crystallised calcium antimonates. A compositions intermediate also identified, suggesting gradual change composition from natron-based towards ash-based technology, prevailed 13th-14th centuries. conclusion, difficulty describing well-defined entity, propensity causes variability compositions, particularly those trace elements, is clearly documented here. any case, this paper contributes new type chrono-typological scanning more detailed knowledge technology during times Italy, little found literature until now.
