A local microscopic model for the formation of silver mirroring on black and white photographs

  title={A local microscopic model for the formation of silver mirroring on black and white photographs},
  author={G. D. Pietro},
English) Black and white photographs are made of a gelatine emulsion containing silver grains laid on a support material that can be glass, plastic or paper. Due to the small size of the silver grains, the corrosion of the silver grains is the starting point for a variety of degradation forms appearing visually different like yellowing, silver mirroring and red spots. In this paper we focus our attention on the formation of silver mirroring, a bluish metallic sheen commonly seen on silver… Expand

Investigations on the chemical degradation of silver gelatine prints
Photographs are considered composite objects with complex chemical and physical structures. Therefore they are more prone to damage as compared to other objects. Chemical degradation is by far theExpand
Silver gelatin prints are composed of multiple materials giving such photographs a complex physical and chemical nature; and for this reason, they are more vulnerable to damage compared to otherExpand

Interdiffusion of aqueous silver nitrate and potassium chromate and the periodic precipitation of silver chromate Liesegang bands
Periodic bands of crystals (Liesegang rings) are formed when a pair of soluble salts interdiffuses and reacts to form an insoluble salt. A classic example is the banded precipitation of silverExpand
Quantum size effects and photographic development
Although it is a key process in silver halide photography, the development of the silver specks of the latent image has not yet received satisfactory explanation, particularly regarding the existenceExpand
On the mechanism of silver and copper sulfidation by atmospheric H2S and OCS
Abstract Hydrogen sulfide (H 2 S) and carbonyl sulfide (OCS) are the principal atmospheric corrodents for silver and copper. To investigate the mechanisms by which the sulfidation reactions occur,Expand
Physicochemical properties of small metal particles in solution: "microelectrode" reactions, chemisorption, composite metal particles, and the atom-to-metal transition
The study of nanometer and subnanometer colloidal metal particles in aqueous solution complements the investigation of small particles in molecular beams, frozen solutions, and inorganic clusters.Expand
The Reduction of Silver Ions on Nuclei by Hydroquinone
AbstractThe reduction of silver ion by hydroquinone on various colloidal nuclei in aqueous gelatin has been examined. The relative effectiveness of the various nuclei depended primarily on size, andExpand
Physical Chemistry
THE larger text-books of chemistry have generally been devoted to describing and roughly classifying the facts which form the foundation of the science. These facts are so numerous, varied, andExpand
Mutual and self-diffusion of water in gelatin: experimental measurement and predictive test of free-volume theory
Abstract Self-diffusion of water in unhardened photographic gelatin is measured by pulsed-gradient n.m.r. spectroscopy. Mutual diffusion and activity of water in hardened and unhardened gelatin isExpand
Electrochemical properties of small clusters of metal atoms and their role in the surface enhanced Raman scattering
Starting with equations for the shift of the reversible redox potential of small metal particles with size, the electrochemical properties of these particles are discussed. Approximate equations areExpand
