Just finished my new darkroom after a 25 year layoff.
I am using Ilford HP 4 film
Sprint chemistry, as close to odless as i have found and they are a good product.
I am searching for a low-odor fixer formula that I can
compound myself from dry chemicals rather than buying
pre-made wet stuff in a jug. Any suggestions?
On other fronts, looks like the vinegar and water solution
should work nicely for the stop.
... Regarding smell, it made difference for me. I print in badly ventilated room btw.
Which makes ammonium thiosulfate and sodium chloride. You know that, of course, but some maybe prefer pre-mixed low odor rapid fix.OF-1 is a "rapidised" sodium thiosulfate fixer with ammonium chloride added, and the pH adjusted for minimum odor.
Correct. I think the old recepies for rapid fixers used sodium thiosulfate plus ammonium chloride because they were easier to find (or cheaper) in powdered form than ammonium thiosulfate, during the first half of the last century.I found out that Ilford Rapid Fix which I use now, contains ammonium thiosulfate. So OF-1 contains same thiosulfate plus sodium chloride, according to JPD?
Well, since fix can't explode, I guess they/we are lazy.Jpd, do you mean that those prefer premixed because they are lazy or is it something else like as to make explosions in the room?

When I think about it, sodium chloride in water separates to Na+ and Cl- ions. I think I remembered Eder wrong, when I thought he wrote that sodium thiosulfate plus ammonium chloride makes ammonium thiosulfate. But I think you will agree if I say that it's just like having ammonium thiosulfate in the fixer?Well, I know enough to know that they don't. Make ammonium thiosulfate and sodium cloride, that is.
In a solution you will have hydrated ammonium, sodium, thiosulfate, monohydrogen thiosulfate and chloride ions. What dry chemicals you choose as a starting point to get these ions in the solution is irrelevant, so you might just as well start with ammonium thiosulfate and sodium chloride - and quite a bit extra sodium thiosulfate, since there's nowhere near enough ammonium chloride in my recipe to equal the amount of (sodium) thiosulfate.
there are a lot to try. I typed "odorless" in freestyle and the list of products popped up. Anyone knows of Arista powder of fixer?
