Large quantities of glass vessels and remains of a large-scale glass industry were retrieved in the excavation at Miska, mostly from the refuse pit in Area A. The glass assemblage mainly dates from the Late Roman and early Byzantine periods (fourth–early fifth centuries CE), showing affinities with several glass-vessel groups, all of which relate to local production centers. The glass-production remains comprised a large amount of raw glass chunks and debris from destroyed furnaces, pointing to a primary production. The remains of the glass industry add important information concerning the history of primary glass production in the region, reinforcing the importance of this economic branch in the region.
