Typical Late Roman Attic lamp fabric (reddish orange, range of inclusions and fracture but well levigated), firing (consistently hard), and surface treatment (thin, uneven, semimatte slip, slightly darker than fabric, brushed harhazardly over top and onto sides). Clean lateral seam, to the extent it is discernible. Cleanly rendered details.
Preservation comment
Two nonjoining fragments, one large (933) and one small (705), preserve 55% from top right and left parts of lamp, including less than one-half of discus, over three-quarters of shoulder down to lateral edge of wickhole, and small part of wall. Slight, sparse abrasion and slight cracking and flaking around edges; mostly clean breaks; infrequent thin patches of encrustation along sides.
