dc.description.abstractABSTRACT: This study explores the materials, manufacturing processes, and corrosion behavior of photozincographic plates from the Lactário Museum in Lisbon, Portugal. Analysis of thirty-three historical plates (1927–1971) and three non-historical plates using stereomicroscopy, micro-X-ray fluorescence, X-ray diffraction, and accelerated aging tests revealed that the plates are primarily composed of zinc with trace elements (lead, iron, and calcium) and produced by distinct manufacturing techniques. Corrosion products containing sulfur-based compounds indicate the influence of an outdoor environment. Accelerated aging demonstrates significant image degradation from corrosion, highlighting the need for tailored preservation strategies for these unique composite objects.por
