Technical Observations: The patinas of the rooster pendants (173.1972, 181.1972, 182.1972, 184.1972, 186.1972, and 1992.256.31) are green with brown burial accretions. 1992.256.31 is entirely black. 182.1972 has layers of iron corrosion products, and the eyes of that object, from which the rust appears to originate, may be made of a circular-sectioned iron rod inserted through the head. The pendants are in stable condition. Some areas are relatively well preserved and appear smooth. The pendants were cast from models made directly in the wax. A minimal amount of cold working was used to decorate the necks, bodies, and tails, perhaps to depict feathers. The decorative incisions were made in the wax model.
