Casgliadau Arlein

The ampulla is incomplete and distorted, missing some of the mouth and the side loops (with a distorted length of 60.0mm and a weight of 62.1g containing sediment). The expanded mouth (with a width of 25.4mm) is damaged and is open. The neck has straight parallel sides and is of oval section (23mm wide and 12mm thick). Stubs from the side loops begin 1 - 2mm above the body and have a length of 12 - 15mm (5mm internal). The body has a maximum width of 36.4mm and a thickness of 8.5mm. The obverse face is convex and is decorated with the scallop motif, representing the emblem of pilgrimage, and has five surviving 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. The reverse face is flat and plain with a bevelled edge. Casting flashes are evident along the edges of the ampulla.
