Four Diafine Formulas

A and B bath, divided, two-bath, or split-stock developers,
whichever you prefer, my interest has been picked by a recent
thread dealing with two-bath film and print developers.

There is the offical formula which is AFAIK unknowen.
Then there is one compounded by Mr. R. Vervoordt, which may
use the carbonate he mentions, in the B solution.

Patrick Dignan's Classic B&W Formulas contains two. An article by
Mr. Ronald W. Anderson deals with substitute formulas; Microdol X,
Diafine, Neofin Blue, and Acufine.

Mr. Anderson gives two versions of the B solution; 65 grams of
S. sulfite and 20 grams of S. metaborate OR 20 grams of borax.
He prefers the borax version and likens it to D-76 "with the
advantages of ... a two bath."

BTW, his A bath formula is, in this order: S. sulfite, hydroquinone,
phenidone, S. bisulfite; 35, 6, .2, and 6 grams. All formulas are
to make 1 liter.

The metaborate version is "Too grainy ..." BUT "...gives more than
a stop true speed increase."

I dug up the info and thought I'd pass it along. Dan

Thanks, Dan. This points me to some info I didn't have.

The Carbonate version I referred to will probably come up somewhere in
the Dignan newsletters; I never had his BW booklet. The first
formulation I used was the substitute published in the newsletter and
it had the basic split that you mention for the A bath and a B bath
with 35 grams of Sulfite with an amount of Carbonate that seemed
fairly large, yet yielded acceptable grain. I can't access any of my
records, as I'm moving yet again, so I can't speak for that figure;
20g, if memory serves. Next year, perhaps.

Regards.

Ooops. Make that 35 grams of Sulfite in the A bath and 65 grams of
Sulfite in the B bath.
