Here s the summary from books and many threads here in Apug about Ansco130
The recipe:
Hot Water (125F/52C) 750 ml
Metol 2.2 grams
Sodium Sulfite (anhydrous) 50 grams
Hydroquinone 11 grams
Sodium Carbonate 78 grams
Potassium Bromide 10%solutions 55 ml
Glycin 11 grams
Water to make 1 liter
AA version is make separated hydroquinone solutions, omit the Bromide and hydroquinone, and reduce sulfite to 35gr /L, then add bromide only as needed to prevent fog
AA said thats: use in full strength for maximum contrast. The result is a brilliant, cool-toned developer.
If you found contrast was too low, add the following hydroquinone
Water 750 ml
Sodium Sulfite (desiccated) 25 grams
Hydroquinone 10 grams
Water to make 1 liter
To dissolves it:
From :

Place the warm water in the storage container and add a pinch of sodium sulfite. (A small amount of sodium sulfite will minimize the initial oxidation of the metol. If more is added at this point, the metol will not dissolve). Add the metol to the solution and stir until all of the metol is dissolved. It is important that all of the metol be dissolved before the other chemicals are added. Add the sodium sulfite, stirring until the solid dissolves, Add each chemical in the order given in the table above. Be sure each chemical is completely dissolved before adding the next one to the solution. Finally, add water to the solution to bring its final volume up to size.
Glycin should be in the neighborhood of white when it's fresh. It gets brown as it gets older. Better way to keep it, is in refrigerator with good sealed
The Fact
- Scott said that: Ansco 130 give beautiful rendition black both in shadow and highlight (it has luminous highlight, and good black with detail)
- Tom Hoskinson in this forums (somewhere) said that tonality : side-by-side print/developer test results comparing Ansco 130/Azo with Michael Smith Amidol/Azo resulted in a small but noticeable tonality advantage for Amidol/Azo.
- Sanking said: when doing the AZO Amidol vs 130 tests yesterday I also tested both Amidol and 130 to see if dilution affects contrast. The answer is basicaly no for both developers. There was virtually no differnce in contrast between AZO when developed in both Amidol and 130 straight, diluted 1:1 and diluted 1:2.
- Photoformulary 130 for whom cannot mix their own brew, is identical with Ansco130
- Ansco 130 Has long long life span, days in tray, even months and months if u keep it in a glass bottle after used it
Ive seen MAS print AZO/Amidol is really2 beautiful, I cant afford Azo nor Amidol, if Ansco130 will make such beautiful prints in enlarger paper, why I dont give a try (Maybe I will use it combine with Ansco120 (that give me nice tonality in middle grey value)
