Glass Bangle Size Ratio
A fragment of a decorated Roman Glass bracelet dating to c.AD 50-200. The fragment has a D-shaped section and is of Kilbride-Jones type 2Ci. The core and body of the fragment is made from a translucent light blue colour glass with the addition of three cords of decoration within the outer edge of the bracelet. The centre cord is of a golden brown, amber like colour and at either side of the centre cord is a cord of opaque white and cobalt blue. The cord decoration penetrates c.0.5mm into the lighter blue glass.
Within the glass are tiny black fragments, which are diagnostic features associated with the winding and stretching technique used during the manufacturing processes and demonstrate the use of metal tools to help form the bangle. The black fragments are iron scales embedded onto the inner surface from its contact with iron rods. Internal folds seen in the cross-sections, indicate that the glass was wound around the rod during the first stage of production.
Length: 23mm, Width;10mm, Depth; 8mm, Weight: 4.5g
Estimated external diameter of the complete bracelet: 80mm; estimated internal diameter of 60mm.
This fragment has been recorded with Dr Tatiana Ivleva who notes that the 'fragment belongs to relatively common type 2Ci. What makes your piece stand out is the use of golden brown (amber-like) glass for the cord decoration. While usually the cords are made in opaque white and cobalt blue, the use of golden brown is relatively rare: I know of 14 specimens out of 700 with fragments found in Yorkshire, Durham, Cumbria, Northumberland and one travelled as far as Scotland'.
