Technical Observations: The mirror surface is green. One small area where the green has flaked off is bright and reflective. There are several areas of damage to the gilding, which have turned dark brown. A reddish lacquer-like residue is present in many areas. The gilt repoussé component has been partially lost. Restoration material fills the gap between this sheet and the mirror itself.
The mirror disc is cast. It is slightly convex on the polished surface and concave on the side attached to the gilt repoussé sheet. The repoussé component is c. 2 mm thick. The repoussé decorations, which are c. 3 mm high for the most prominent figures, were impressed from the reverse. The lack of crisp detail in the relief is because the sheet was not worked from the front. Although it is possible that molds or sculpted stamps were used in pressing the decorations, there is no visible evidence of this, such as identical patterns in the border design. Although the back of the cast mirror is exposed, there is no obvious residue of the adhesive or solder that might have been used to adhere the gilt sheet. The bottom edge of the small mirror was filed flat over a 2.5 cm length. A bracket-shaped impression in the corrosion products on the mirror side at this location indicates that a handle, hinge, or similar element was once attached there.
