Abstract Previous analytical studies show that most of Northern Italian glass has been heavily recycled and mixing natron plant ash was occurring (Verità Toninato 1990; Verità et al. 2002; Uboldi 2003; Andreescu-Treadgold Henderson 2006; Silvestri Marcante 2011). The re-use “old Roman glass” interpreted as stagnation in trade from the primary production areas. However, reintroduction on sites such Torcello, Nogara, Lombardy at same time it reintroduced Levant, strongly indicates long-distance contacts with Levant least eighth century CE. This paper addresses key issue recycling by focusing compositional nature traded reworked Italy after seventh CE set a broad Mediterranean context analysing major, minor, trace elements eighty-nine samples (seventh to eleventh AD) workshop Piazza XX Settembre, Comacchio.
