Technical Observations: The patina is green with underlying red and spots of blue. Small areas of brown accretion are found overall. The surface is well preserved, and the handle is intact.
The handle is a hollow cast. Chisel marks on the back surface show how the wax model was adjusted to fit the surface of the vessel. Direct wax manipulation of the back and interior surfaces is an indication that the wax model was cast in a mold as part of the indirect lost-wax technique. The mold-made wax model may also have had additional relief detail worked on the surface prior to casting. The finer lines on the bust of the figure appear to have been stamped directly in the metal. The lead used to attach the handle to the vessel at both ends also appears to have partially or completely filled the hollow interior. Much of it has corroded and is now white.
