Sandy King posted a recent bit to the Black and White Forum expressing a curiosity about glycin based developers and about glycin combined with ascorbic acid in developers. He got the usual collection of replies and formulae, none of which really addressed the inquiry very well. I got thinking about the subject, however, and I decided to try a few things. My first experiments were directed at Ansco 130 print developer. This well known formula is noted for its neutral tones and excellent...

My little variation of 130 use 80g sodium carbonate and 15cc 1% benzotriazole solution instead of the bromide. I print on Ilford warmtone FB and I just love the combo. The high carbonate gives wonderful blacks...EC

Ansco 130 has a reputation for very long life.
I just wonder if your A. Acid version will be so
long lived. Do you happen to know if glycin and
phenidone and no other agent are a workable
combination? Dan

dancqu: I can't see any reason why it wouldn't be long lived, but the only way to really find out is to test it. Ascorbic acid is an anti-oxidant, and, if anything, it should inhibit any deterioration. I haven't tried it, but it should also be possible to mix this developer as two stock solutions, keeping the carbonate separate. This is a well known technique for extending the life of Ansco 130.

I can see a reason it won't be long-lived: you're dissolving ascorbic acid in water. When I do that, activity is almost gone the next day, regardless of concentration or pH. You need tricks to keep ascorbic acid active in water.

hey - where the hell can I GET glycin anyway....???? I looked on digitaltruth - and they've got a LOT of great stuff... but no glycin! Any leads? I was going to mix up some 130 just to try out...

Photographers Formulary is the only place you can get it -- that I know of. I've also found that tightly saled and kept in the freezer it will keep longer than most folks claim.

I mixed up some of this developer about a month ago and just got an opportunity to try it this past weekend. I made it without the sodium carbonate, and used it as a two-bath developer, with the carbonate in the second bath.

The developer worked just fine with Kentmere Bromide and Kentona papers. Both had a very cold, somewhat blue, tone.

Thought I'd drop a note regarding this... I had been looking for something to make use of a large stash of FB WT Ilford that had disappointed me in my normal soups. This combo was exactly as you state. It really added some pizazz to this paper for me. The blacks are great with an interesting velvety finish and the highlights sparkle in a way that seems just right for this paper. I'm really glad to have stumbled into this one! Thanks!
