Technical Observations: The patina is a very dark green. Possible inlay material above the cobra is missing. There are small break surfaces at the bottom left and right edges, indicating losses there.
The object was cast by the lost-wax process. The wax model was constructed by combining separate pieces for the uraeus, its headdress, the large feather, and the twisted horn at the bottom. Wax manipulation marks and joins between these pieces are visible at the back. Fine wire inlay over much of the front surface is red and green, and it is likely that the wire used for this inlay was copper or another copper alloy. Fine scratch marks at the back appear to be original finishing marks in the metal.
