The site and the PDF with the recipe are gone. Do you remember what kind of developer was in there?

Fortunatelly not, that would be insane I'm sorry

oh!! That's so amazing! Thanks!
I am reading the formula. That's interesting. Almost a Kodak D96 but on phenidone instead of metol. That made me curious and I will definitely mix it. Have you tried it?

Alain,

If you or someone could translate the German into English, I would be most appreciative. This is my best guess:

Water 750 mL
trisodium phosphate 2.00 g
sodium sulfite 100 g
hydroquinone 2.50 g
phenidone 0.30 g
sodium tetraborate decahydrate 2.00 g
potassium bromide 0.39 g

fill with water to 1 liter

I am not really sure about the second one (the trisodium phosphate).

Does it say anything about dilutions or times?

Actually, you can rewrite as it follows:

Water 750 mL

~~trisodium phosphate 2.00 g~~ - not needed for distilled/demineralized water
sodium sulfite 100 g
hydroquinone 2.50 g
phenidone 0.30 g
borax 2.00 g - "sodium tetraborate decahydrate" it's the chemical name of borax
potassium bromide 0.39 g

Water up to 1000ml.

Does it say anything about dilutions or times? - No, it gives 3 to 5 minutes at 21 Celsius. I would go with 5:30 minutes at 20 Celsius.

I have not used it. Just looked into it.

But you maybe shouldn’t leave out the trisodium phosphate without adjusting the pH. It’s a very strong alkali and without it you may have a slightly low pH. Although with all that sulfite in there, that’s likely to dominate.

I came across the ORWO 1182 and 1183 docs. In the german version the Pentanatriumtriphosphat chemical is translated in the english version as Sodium Tripolyphosphate - STPP which is used in detergents to sequester metal ions (calcium and magnesion) which lead to water hardness so acting as a water softener.
