FILIGRANA is a collaboration between the Milanese bistro Altatto and 6:AM Glassworks, established in 2021. This project integrates contemporary culinary practices with traditional Murano glassmaking. Each piece is crafted using the Muranese ‘a canne’ technique, where glass canes are fused and blown into a wooden mold by master artisans. The items undergo coldworking and are hand-signed.
