Technical Observations: The patina of these pins (164.1972, 1969.190, 1992.256.69, 1992.256.120, and 2004.196) is green with areas of dark green and red. Some burial accretions are present. The decorative top and the rod shape of the pins were probably cast using an indirect lost-wax technique. It is likely that the tapering point of each pin was refined by hammering. Finer details in the decorative tops may also include punching, such as the chevron lines in 2004.196. The soft fluid shapes of 164.1972 probably indicate direct work on the wax model.
