This article provides an overview of the infills and retouching materials applied to paintings on this metallic support from 1790 to 2022. The research identifies at least eight historical written sources produced before 1899 and fifty-five contemporary sources produced between 1900 and 2022. The range of products and procedures applied varies from traditional materials like carbonate calcium mixture with animal glue to synthetic resins, and from using brushes to carving heat pencils for application, respectively. Exploring the diverse practices over the last two centuries will not only help conservators make informed decisions on which materials and techniques to use during painting on copper restoration, but will also aid scientists in accurately interpreting the data collected from these objects during scientific analyses.engFillersRetouchingConservation and restorationChromatic ReintegrationCopper SupportPaintingsEnchimentosRetoqueConservação e RestauroReintegração cromáticaSuporte de CobrePinturasjournal article10.5281/zenodo.14591488
