Optical microscopy, BSE images, and X-ray elemental maps of cross section S12 (metal alloy and corrosion products). a Image of the Morse sculpture in Central Park’s conservation laboratory. The red arrow indicates a location on the statue from which a multi-layered sample was removed for analysis of the metal alloy and corrosion products (sample S12). b Polarized light micrograph of sample S12 mounted as a cross section. c BSE image of the portion of sample S12 indicated by a red square. The red and green arrow indicates changes in composition within the stratigraphy when moving from the main metal alloy up to the surface. d X-ray elemental maps of copper (Cu), chlorine (Cl), tin (Sn), and sulfur (S) collected from a portion of cross section S12
