Technical Observations: The patina is a very dark green and black with areas of raised lighter green corrosion products. Half of the handle is covered with coarse, raised corrosion products and black burial accretions. The other half appears to have been cleaned carefully revealing a surface that is well preserved in areas. An 8-cm section of the central knob and a 1.5-cm section of one side knob have been lost and are filled with wax.
Irregularities in the shapes of the object give the impression that the wax model from which it was cast was probably made directly rather than cast in a mold. There are striations in the four deep grooves where the handle attached to the rim of the vessel, indicating that they were dressed abrasively after casting in order to receive the rim. The slender upper walls of the grooves would have allowed them to be bent tightly around the rim in order to hold the handle in place. There are no visible signs of a solder.
