Argyrotype is an alternative process exposed by Ultra Violet/Sunlight through the use of contact negatives to produce a continuous tone brown image on art paper of your choice. Argyrotype is a user-friendly iron-based silver printing process that produces brown images on plain paper. It is derived from the Argentotype, Kallitype, and Van Dyke processes of the 19th Century, but has greater simplicity, improved image stability, and longer sensitizer shelf-life. Each kit contains chemicals, paper, gloves, glass rods and other ancillary equipment necessary for each process. Requires contact frame or plexiglass (not included).
