Photographers' Formulary 10-0610 100G Overview

Glycin (N-Para-Hydroxyphenyl) from Photographer's Formulary is an excellent developing agent for both film and paper. It is fine grain, ultra clean working, lengthens the life of phenidone, and produces attractive warm tone prints with the subtlest highlights.

Until the advent of 35mm film, with the resulting emphasis on fine-grain developers, glycin was used mainly in paper developers. Now it is sometimes used in combination with other developing agents for fine-grain film development.
Print craftsmen and women long ago recognized the Ansco 130 formula based on glycin as the experts choice. Ansel Adams used a modified version of it for some of his very finest work.

Synonyms
Glycin
Para-Hydroxyphenyl glycine
Para-Hydroxyphenylamino acetic acid
Athenon (Kodak)
Glyconol
Iconyl
Kodurol
Monazol (Edwal)
Appearance
Glistening white or gray powder
Uses
Non-staining, clear working developer; gives fine-grained negatives of a gray black color.
Commonly used with para-phenylenediamine in fine-grain formulas; also used in paper developing formulas.
Chemical Formula
C8H9NO3
Notes
Glycin is almost insoluble in water, but it dissolves readily in alkaline solutions, thus it should be added last to any developer formula. It oxidizes very slowly and is very clean working.

Glycin is very sensitive to bromide and low temperatures. With alkali carbonates, it makes slow-working developers, which have good keeping properties and give low contrast. Must not be confused with glycocoll medicinal, sometimes called glycine.

question

How long can Glycin be stored without opening the package?
Asked by: Tase T.
The shelf life of glycine powders and 10x stock solutions can exceed 1 year. However, as glycine ages, it becomes oxidized and may yield yellow-colored solutions. This may affect the pH of the solution. If yellowing occurs, it is recommended that you replace the product.
