A photographic printing-out paper widely used from about 1850-1890. Albumen paper was invented by Louis Desiré Blanquart and presented to the French Academy of Sciences in 1850. Blanquart used a thin layer of egg white protein to disperse and bind photosensitive salts. Egg white was whipped then allowed to settle to a liquid; this formed a homogeneous liquid which was mixed with small amounts of salt (usually sodium chloride or ammonium chloride) and citric acid, then spread as a thin layer over a high quality cellulosic paper. After drying, the layer was activated by treatment with silver nitrate to form silver chloride, a light sensitive compound. To create an image, a negative was placed in direct contact with the paper, then exposed to daylight. Once the development was complete, it was stopped by treating the paper with a fixing agent such as sodium thiosulfate. Albumen prints were a golden to purplish brown color with a glossy surface. It was replaced in the 1890s by silver gelatin paper.
