Photographers' Formulary said I could "go ahead and use the glycin" which has turned cocoa colored (outdated, although they don't put expiration dates on the container) in the Ansco paper developer which I mix according to Anchell's Darkroom Cookbook. I have mixed it and used it on Forte VC fiber paper (and Ilford RC for contact sheets). Prints from a Bergger neg look good, but prints from an HP5+ neg have blasted highlights, regardless of burning (detail is in neg). Is the age of the glycin a factor?
