Technical Observations: The patina is heavily corroded with predominantly green corrosion products. The two pieces join, but there are some losses around the join. The thick corrosion obscures the surface detail. The copper-alloy fork was probably made by casting the rough shape and then working it to further shape the fork and finish the surface.
