The albumen print was invented in 1850 and was the most common type of print for the next 40 years. It produced a clearer image than its predecessor, the salted paper print. An albumen print was made by coating paper with a layer of egg white and salt to create a smooth surface. The paper was then coated with a layer of silver nitrate. The salt and silver nitrate combined to form light sensitive silver salts. This double coated paper could then be placed in contact with a negative and exposed to the sun to produce a print.
