Glycin Developers for Film

[David A. Goldfarb]

I have not tried these, but since people are experimenting with Ansco 130 as a film developer, they seem to be of potential interest. These come from The Morgan & Morgan Darkroom Book, ed. Algis Balsys and Liliane DeCock-Morgan (Dobbs Ferry, NY: Morgan & Morgan, 1980), pp. 152-55. The book has some obvious typos, like a recipe for Agfa #12 that leaves out the developing agent, so if anyone can confirm these from other sources, that would be helpful.

Agfa #8--Normal Contrast Glycin Developer

Warm water 52 C--750 ml
Sodium Sulfite, desiccated--12.5 g
Glycin--2.0 g
Potassium Carbonate--25.0 g
Add cold water to make 1.0 liter

Development time for ASA 100-125 films is 10-12 min. at 20 C

Agfa #72--Soft working developer

Water 52 C--1.0 liter
Sodium Sulfite (anhydrous)--125 g
Glycin--50 g
Potassium Carbonate--250 g

For tank development, dilute 1+10 and develop at 18 C for 15-20 min.
For tray development, dilute 1+4 and develop at 18 C for 5-7 min.

Gevaert GD-202

Metol--1.0 g
Sodium Sulfite--32.0 g
Glycin--0.5 g
Hydroquinone--0.5 g
Sodium Carbonate--28.0 g
Potassium Bromide--1.5 g
Citric acid--1.0 g
Water to make 1.0 liter

"If exposure has been correct, the film will be properly developed in 10-12 minutes."

Kodak D-78

Water--750 ml
Sodium sulfite (anhydrous)--3.0 g
Glycin--3.0 g
Sodium carbonate (mono)--7.2 g
Water to make--1.0 liter

The average development time is 15 to 25 min. at 18 C.

TP-78, a film developer formulated for Tech Pan
and similar high contrast slow speed films.

In this order; 1.5 grams, 3 grams, 3 grams -
sulfite, glycin, carbonate. A less sulfited, less
carbonated version of D-78.

Thanks Dan.

And according to Wynn White, that's to make 1 liter. He develops Tech Pan at EI 25, 6 min agitating every thirty sec.; Bluefire Police at EI 25, 10 min. with less agitation (see the website for the schema).

There are a lot of Formulae once posted on APUG stuck in a Black Hole somewhere . . . . . . Ideally they should be restored.

FWIW, that Morgan and Morgan darkroom book, I have also found, has a considerable number of typos and other errors in its formulary. I packed it away years ago rather than rely on it.

Unfortunately many US books of Formulae going back to the 40's/50's Lab Indexes are riddled with errors & typos, and every new book just kept compounding the errors. Steve Anchell's new Third Edition of the DCB has been cross checked were possible with the manufacturers own published data, but even those occasionally had the odd rare errors. So many errors which went unspotted in the 1st & 2nd editions and many other previous books are corrected in the 3rd Edition

Water 750 cc, 125 deg.
Metol 7 g.
Sodium Sulfite (anhydrous) 70 g.
Paraphenylenediamine 7 g.
Glycin 7 g.
Water to make 1L

(Note, as usual, a pinch of Sulfite in the water before Metol.)

I use this full strength. My normal time in a Jobo for TMY is 6"30" @68 deg. F, water stop, fixed in Hypam 1+4, washed. This pulls highlights down quite nicely with minus development and is responsible for about 70% of all my film development...Evan Clarke

I have a box of FX-2 film developer (contains glycin) that I'm wanting to try for stand development. In the mixing instructions for Stock Solution A, it's stated that:
"Add a pinch of the sodium sulfite".
However, there is no mention of when the rest of it goes into the solution. Does it go in last after the Metol, and the Glycin has been dissolved?

Also, when making the working solutions, for both versions with development with agitation and stand development, it suggests on the final line to add 500 ml Water, or 1,000 ml water to make a 0.5 liter or 1 liter solution. I'm just making sure, as I'm a believer in 'there are no stupid questions' thing - but hopefully that means to add water to bring the total volume to 500 and 1,000 ml respectively???

Where can I get syringes to measure up 1/10ml accuracy???



Recipe from Photographer's Formulary:

STOCK SOLUTION A
Chemical Amount
Distilled Water (32° C/90° F) 900 ml
Sodium sulfite, anhydrous 70 g
Metol 5 g
Glycin 15 g
Distilled Water (32° C/90° F) water to make 1000 ml

Place 900 ml of water in the brown storage container, or in a mixing container. Add a pinch of the sodium sulfite.
This small amount of sulfite minimizes the initial oxidation of the metol. If more sulfite is added at this time the
metol will not dissolve. Add the metol to the solution and stir until dissolved. Add each chemical in the order
given, being sure each one is completely dissolved before adding the next. Glycin sometimes goes into solution
rather slowly, so be sure it is mixed thoroughly before adding the rest of the water. Finally, add water to bring the
total volume in the container up to 1000 ml and stir to ensure the solution is mixed thoroughly.

STOCK SOLUTION B
Chemical Amount
Distilled Water (32° C/90° F) 800 ml
Potassium Carbonate, anhydrous 123 g
Distilled water to make 1000 ml

Add the water to the storage container followed by the carbonate. Cap and shake the container to dissolve the
solid. Add water to bring the final volume up to 1000 ml. Cap and invert the container several times to ensure the
final solution is mixed thoroughly.

Thomas, after the pinch, mix ingredients in order of their listing...Evan Clarke

[Thomas Bertilsson]

Hi Evan, thanks for helping out! But then I am adding the rest of the sodium sulfite next, which it tells me not to do. Or do I not add the rest of the sodium sulfite? It's first on the list.

OOPs, I make this quite a bit and was trolling from memory. This formula is not in order, it goes: the pinch of Sulfite, te Metol and then the gross amount of Sulfite..Sorry...Evan

[Thomas Bertilsson]

Thank you for getting me the right order!

I have a box of FX-2 film developer

Hi Thomas,
could you tell me please what is a ratio of mixing A+B+water to make the working solution in the instruction you have?
Thanks.
