Casgliadau Arlein

The ampulla is near-complete, missing the side loops only (with a length of 57.0mm and a weight of 57.7g containing some sediment). The expanded mouth (with a width of 26.6mm) is damaged and partially open. The neck has straight parallel sides and is of oval section (21mm wide and 9.0mm 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 37.3mm and a thickness of 10.5mm. 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.
