“Forum ware” is considered the earliest glazed pottery of the Medieval West. Named after the substantial find of 80 complete jugs and numerous fragments in late 19th century excavations of the Fons Juturnae in the Roman Forum, it is traditionally dated between the 8th and 10th centuries, influenced by imported Byzantine glazed wares of the 7th centuries. The pottery is single fired with glaze on the interior and exterior. Production seems to have been concentrated in the Roman Forum and Imperial fora after their transformation from public space into residential and workshop areas in the Medieval period. The style continues into the 13th century with thinner surface glazing. The Crypta Balbi (Museo nazionale romano).
