Anotations

Scope note:

Albumen paper was a widely used photographic printing material from about 1850-1890, when it was superseded by silver gelatin paper. Invented by Louis Desiré Blanquart and presented to the French Academy of Sciences in 1850. Manually coated sheet by sheet with egg white combined with a small amount of salt, when dried, the coated paper was sensitized by the user by floating on a silver nitrate solution. After exposure to sunlight under a negative, the image would be gold-toned and fixed with sodium thiosulphate. The last commercial production of albumen paper is believed to have been in 1929.
