Kodak Polytoner and alternative sepia/sulfide toners

There may be a substantial difference, whether you use this substitute directly or indirectly. Used directly the Ammonium Thiosulfate probably doesn't hurt at all, whereas it could make indirect toning a gamble.

As I always used it directly, that was never a question to me. But if you want to work indirectly, you can just split the steps and never join the components for sulfur and selenium in the first place which also adds some more freedom which to some may cause insecurity whereas others just squeeze it until it's lemonade.

Not very diligently, but I did dunk one or two small lith test prints into this toner. It seemed to work just fine!

That's indeed very encouraging! Thanks.

Maybe a little more detail: I tried the preparation made from sodium sulfite and plain sulfur, as well as the sulfer + sodium hydroxide preparation. Both in fairly random dilutions of something like 1+50 or so, as a direct toner, on small lith prints. The lith prints were on Fomatone and pink-ish to begin with. Toning was very swift; I totally overshot the mark with the first one within a minute, turning the pink into a dull brown. The other print I treated more carefully (I think the toner was more dilute as well; I was winging it really) and shifted more subtly. The smell was typical rotten egg and quite powerful at that.

JADAM Sulfur (without salt and soil) is essentially a polysulphide concentrate. It works nicely at 1:100 dilution as a toner for both Kallitype and Cuprotype prints.
 

A similar idea was tested by Gerald C Koch and confirmed that it yields good results:

T-8 Polysulphide Toner Questions/Modifications

Trying to find some information on the T-8 Polysulphide toner listed in Tim Rudman's toning book and Steve Anchell's "Darkroom Cookbook" and it's relationship to the Kodak Brown toner in terms of usage and modification. Anyone have any insights into the following questions? Can the T-8 toner...

To make 100 ml of the toner concentrate as per Dr. Youngsang Cho's instructions for JADAM Sulphur:

Sulphur: 25 g
Sodium Hydroxide: 20 g
Water: 50 ml

Add the ingredients in the above order. Use a glass beaker with capacity 500 ml. The reaction generates substantial heat, so wear appropriate protective equipment. The mix changes colour as it starts digesting Sulphur. Once the reaction is complete and the solution has cooled down, filter it and add cold water to bring the volume to 100 ml. Store the solution in a glass bottle, tightly stoppered and away from light.

Dilute the concentrate appropriately before using for toning.
