Technical Observations: The patina on the front is brown and green with areas of red and black. The back is mostly green. There are tan burial accretions and rust staining from a corroded reinforcing plate and the links.
The object was fabricated from sheet bronze, with an iron reinforcing plate attached to one end with copper alloy rivets. The plate and sheet are crudely pierced by eight holes, four of which retain heavily corroded remains of loops. A portion of the now-mineralized iron reinforcing plate is intact on the back. Preferential corrosion of the iron has assisted in protecting much of the underlying bronze surface, where inscribed layout lines that bisect the holes are observable. The top edges and contours of the holes are chamfered through the burnishing action of the chain loops against the metal; the holes, originally circular, now have a stretched or oval appearance. The other short end of the ornament is pierced by two holes, similarly chamfered, one of which has a corroded iron attachment.
The front decoration was created by punches and engraving. Points, circles, and short lines were made using punches with these shapes. Longer lines were made with repeated hammer blows to a tracer tool. Fainter lines appear to have been made more freely by drawing a point across the surface of the metal.
