Title |
Iron Age glass bead (profile) |
||
Description |
English: Glass cobalt blue bead, circular in plan and oval in profile and section with a large offset circular hole. One side of the bead is thicker, in height, than the other by about 0.5 mm. There is a slight spur on the edge of one side of the perforation, suggesting that the glass has been rolled on a central rod, and pulled off while still hot.
Irregular beads made of this dark blue glass have been found in Iron Age, Roman and Post-Roman contexts. There is a very similar example (2005.26.14) excavated from Castle Dore on display in the Iron Age case at the Royal Cornwall Museum. Quinnell (2004) illustrates similar examples from Trethurgy on page 92, Fig.52, Nos.19-20, which are dated to the 4th century AD. Crummy (1983) illustrates a similar example on page 33, Fig.34, No.562, which is dated to the Post-Roman period. |
