Materials & Techniques
Albumen is a binding agent made from egg whites, popular for producing photographs from 1855–1895. When applied to paper, albumen acts as a ground for the application of photosensitive silver nitrates. Albumen paper, invented by Louis-Désiré Blanquart-Evrard in 1850, created a smooth surface for suspension of the image, improving detail and tonal range. The paper is sensitized in silver nitrate, placed into a printing frame, and put into contact with the negative glass plate before being exposed to strong sunlight. Exposure is monitored for the desired density and then the print is removed from the frame before being fixed, toned, washed, and hung to dry. The manufacture of pre-made albumen paper was a booming business in the late 19th century; in 1894, one producer reported using sixty thousand egg whites each working day.
