Tetanal Eukobrom

OK- who is the expert on this paper developer? I'm looking to try it with the
Foma MG paper. Is it worth my time to hunt it down and try or stick with what I know best?
Thanks, Peter

I'm still waiting for my bottle. I ordered it from a Swedish photo store about one month ago. So I guess in any case, if you want to try it, you might have to wait...

Hi Peter, I'm certainly not an expert on Eukobrom, though I have used it in the distant past (1960-70). My recollection is that it produced results similar to Dektol.

I just took a look at the Eukobrom (Liquid) MSDS and the ingredients are:

Water
Hydroquinone
Potassium Sulfite
Potassium Carbonate
Sodium Hydroxide

Eukobrom is said to give: "rich blacks and glowing highlights."

Eukobrom may be similar to the warm brown/black tone Agfa 120 paper developer (a Hydroquinone/Carbonate paper developer with no bromide).

Ansco/GAF 120 is a soft working Hydroquinone/Carbonate paper developer WITH bromide).

Ansco/GAF 110 is a normal working Hydroquinone/Carbonate paper developer WITH bromide). Ansco/GAF 110 is said to give "beautiful warm brown-black tones."

silverprint uk says of Eukobrom liquid:

"Cold-working liquid print developer, giving cold tones on bromide paper, and relatively neutral tones on chloro-bromide papers. Yields an especially pleasing blue-black colour with Forte Polygrade."

Tetenal says of Eukobrom:

"gives rich blacks and glowing highlights."

You may want to consider Ansco/GAF 110 with reduced bromide or no bromide - or with the bromide replaced by Benzotriazole.

I've used for years at this school. Our preferred developer (as it was the cheapest!)
it is ok.
a little cold on most papers I have tryed.
I use it also with liquid emulsion as a high grade developer. (AGFA NEUTOL WA as softer, and TETENAL Centrabrom as soft developer..)
so it seems it works a little harder than Agfa...

Tom and Gandolfi-thanks for the tip off. The Ansco 110 sounds like it might be up my alley. You know alot of these old formulas never work on present day papers but I'll try. I also have some Neutol WA I'll try. Look foward to a fairly comprehensive review of the Foma MG and Adox Vario G. There's only one way to find out what a paper can do. Thank god this is Analogue! Again thanks guys!

Here's the Ansco (GAF)110 Formula:
H2O 750ml
Hydroquinine 21.2G
Sodium Sulfite,dessicated 57G
Sodium Carbonate,mono 75G
Pottassium Bromide 2.75 G
H2O to make 1L

For use 1 part stock to 5 water
Give prints 3 to 4 times normal exposure and dev. 5-7 minutes@68 degrees

Called a direct brown-black paper developer: "beautiful warm tones may be obtained on both contact and projection papers.

Tom Stanworth · Oct 18, 2005

it is very cold, but fine if this is your intended output. Produced a blue black on warm bases with warm papers!

George Papantoniou · Oct 18, 2005

I have lately started to use it, so my experience is not really big. I can yet say that I am satisfied with the results so far. It could be compared with Dektol. I cannot say if it's making warm papers get colder... I'll soon try it with Polywarmtone...

Adrian Twiss · Oct 18, 2005

I have used this developer quite a bit. It does produce tones on the cold side of neutral but not as cold as either Doculith or Maxim Muir's Blue Black Developer (also known as Maxim Muir's Hotshot). I find that it suits my current taste for cool images and very easy to use. I wish the formula was availabe because I can only get it in litre containers. No one will ship 5 litre bottles.
