The object is generally in excellent condition. A small hinged lid on the top of the head opens to reveal a glass inkwell about 2 cm deep. Traces of greenish corrosion are found around the mouth, and a smooth patch of red corrosion on the proper left side of the neck. Overall the object has a dark, brassy color.
X-ray fluorescence analysis indicated that the object is cast from a high-lead (10 percent) copper alloy containing both tin (7 percent) and zinc (10 percent) in comparable concentrations. trace constituents are antimony, nickel, silver, and arsenic. The lips and the band along the edge of the cap, evidently specially patinated to redden them, are relatively rich in copper. The eyeballs and sockets with their thick deposit of gray, rustlike corrosion are significantly rich in iron, suggesting that iron- containing decoration was applied after casting. A fill in a casting flaw on the right temple, which is richer in lead and tin than other parts, is consistent with a lead-tin solder. That the alloys used are consistent with pre-modern metallurgical techniques does not preclude modern manufacture.
