Technical Observations: The patinas of these small goat pendants (170.1972, 174.1972, 176.1972, 177.1972, 187.1972, and 1992.256.28) are mostly green with black corrosion products; some have brown accretions. The rough corrosion products obscure some parts of their surfaces, but in other areas, the surfaces are well preserved. Small losses reveal significant deep mineralization.
The pendants were cast from wax models formed individually by hand. Where preserved, the surfaces appear very smooth and perhaps burnished. There may be some cold work finishing in the details of the necks and faces of some figures, but most of the surfaces are only smoothed and have no decoration.
