The procedure of making an albumen print

1. A piece of paper, usually 100% yarn, is coated with a mixture of egg white and salt, and then dried. The albumen seals the paper and creates a slightly sleek exterior for the sensitizer to rest on.

2. The paper is then dipped in a solution of silver nitrate and water which renders the surface responsive to UV light.

3. The paper is then dried in the absence of UV light.

4. The dried, prepared paper is placed in a frame in direct contact under a negative.

5. A bath of sodium thiosulfate fixes the print’s exposure, preventing further darkening.

6. Elective gold or selenium toning improves the photograph’s tone and stabilizes against fading. Depending on the toner, toning may be performed before or after fixing the print.
