Chemical Composition: ICP-MS/AAA data from sample, Mixed Copper Alloy:
Cu, 73.75; Sn, 4.35; Pb, 10.92; Zn, 9.07; Fe, 0.51; Ni, 0.06; Ag, 0.16; Sb, 0.66; As, 0.52; Bi, less than 0.025; Co, 0.013; Au, less than 0.02; Cd, less than 0.002
Technical Observations: The patina is a varied green, with red corrosion products and brown burial deposits. The piece is intact; there are visible casting flaws, and the surface has worn areas. The attachment was cast, probably in a two-part mold. There is excess metal on the edges that flowed along the join of the two molds during casting.
