Fragment comprising rim and upper wall of a bowl. Straight wall, with a slight, gentle curvature at the level of the rim. A V-profile incised groove defines the junction between rim and wall. Straight lip, slightly thickened and inclined inwards, with angular edges showing slight fire-polishing.
This bowl is of particular significance within the Roman glass industry of the north-western Iberian Peninsula, as its manufacturing technique, based on the juxtaposition of two glasses of different colours, has not been documented in any other published example.
