Technical Observations: Where the patina is well preserved, it is grayish green, and several light green pits are present. Overall, the handle is very well preserved. Most of the fine cold working is preserved in the top corrosion layer.
The handle was cast using an indirect lost-wax process. Parallel lines where the snakes would have been in contact with the basin bear the impression of incised lines that would have matched the rim of the vessel. These were probably produced by fitting the wax model to the rim before using it to cast the bronze. Dark brown layers that are present only on the contact surfaces may be the remains of a solder. The finer decorative incised lines were created by cold working with a tracer tool and fine punches. Fine dendrites are visible over most of the surface of the handle.
