The ampulla is near-complete, missing the side loops only (with a length of 59.3mm and a weight of 55.3g containing some sediment). The expanded mouth (with a width of 26.1mm) is damaged and is partially open. The neck has straight parallel sides and is of oval section (22mm wide and 12mm thick). Stubs from the side loops begin 2 - 3mm above the body and have a length of 12mm (3mm internal). The body has a maximum width of 38.2mm and a thickness of 10.6mm. The obverse face is convex and is decorated with the scallop motif, representing the emblem of pilgrimage, and has seven bold and curved ribs producing a corrugated effect, of Spencer (1990, p59), Type I. The ribs are wider at the base and narrow towards the neck, with the suggestion that they continue and weaken along the neck. The reverse face is flat and plain with a bevelled edge. Casting flashes are evident along the edges of the ampulla
