Technical Observations: The surface is heavily mineralized and has been transformed into a very porous, green amorphous mass and full of cracks and chips—most noticeably on the tip of the nose—that expose a red cuprite layer.
The head is a solid cast and was made in one piece. Some very fine details in the face and the curls on the back of the head are visible through the corrosion, and these details must have been worked both in the wax and the metal stages.
