Summary/Abstract: Searching for an accessible and easy-to-perform photographic process, in 1871 Richard Maddox invented gelatin silver dry plates. In 1879, mass production of readymade photographic media began, making the gelatin silver process the most widespread by the middle of the twentieth century. One of the most characteristic and common changes in the state of gelatin silver photographs is the appearance of a surface veil of silver particles, known as silver mirroring, which interferes with the aesthetic perception of images. The silver mirror is a serious problem facing institutions that preserve valuable photographic collections. Conservators offer many methods to eliminate this unwanted effect most of which are too risky for the photographic image or cannot be applied to all types of photographs. In 2018, Jordi Mestre and Rita Udina, a team of Spanish scientists, offered a new method that seems much safer and easier to apply. They use a combination of solvent and calcium carbonate to mechanically remove the silver film from the surface of the image.
