Technique: Fabrication Method
rod/wire Note: 3-sided rounded circle with opening in middle of one of the sides, rounded stock, with slightly tapered ends. Cast stock, very pitted and porous, with dendritic structure visible on outer surface; suggests not a finished piece (early form of ring in process?). Workhardened. Distortion/torque from use, opening, or from stage of hammering. Long striations recessed into and parallel to length of wire, possibly result of compression in forming (or rolling into round stock). Flat planar surface on anvil side, more dished and faceted on hammered side. One end more rounded and finished, other end more crystalline, uneven appearance due to breaking from trimming.
Treatment: Conservation Performed
Surface cleaned/degreased with acetone on cotton swab
