Ed Buffaloe would love this kind of stuff (probably? :-)(posted 8178 days ago)I forgot to say Foma FV-11 formulae call for anhydrous carbonate (30g) and sulfite (45g) and water to make 1 liter. Foma's recommendation is about 3min at 1+1, 8min at 1+3, 15min at 1+5.
Here's a Pextral two-bath solution.Bath 1:
pyrocatechin 1.5g
sodium sulfite anhydrous 0.3g
water to make 300ml
process for 2 min at 20C
Bath 2:
sodium hydroxide 6g
water to make 300ml
process for 1 min at 20C
Metol can replace pyrocatechin. But what's the point? The formula looks pretty harsh and old, needs some radical modification but this is the only two bath formula using pyrocatechin that I know of! (BTW, does anyone care to comment on DiXactol??
I found these at Leszek Major's homepage.
