Technical Observations: The patina is green with areas of red. Some areas are completely mineralized, although the handle appears stable and strong. The surface has been carefully cleaned mechanically, revealing much of the original detail.
The handle is a hollow cast, and gray core material is visible at both of the open ends of the casting. The relief designs and general shape are fairly complex, and given that multiples are often made of vessel handles, it is likely the wax model was made indirectly using a mold. Many details would have been cleaned up working directly in the wax, but very fine lines, such as the strands depicted within the locks of hair, were cold worked in the metal with a tracer tool and punches. The gray core is very fine and homogeneous. Black flecks of charcoal at one end are not part of the core itself but rather come from the burial accretions on top of the core and on top of some metal surfaces.
