Liver of sulfur- Diluted or not?

[norm123]

Hi
I want to try a polysulphide toning for the first time. I'm using Ilford RC paper and I made D-72 develloper.
I bought Photographer Formulary pack. There is no data about dilution to use. In the Rudman's book, it say that a more toning result is possible with a high dilution but it doesn't seems
specific with liver of sulfur. I don't know if I should dilute or not. It's not clear for me.

Thank you for advise
Regards

The instructions for use are on page 2.
For direct toning, you use the solution undiluted. Direct toning means you tone the print without bleaching it first. So you develop it, fix it, then wash it thoroughly and then it goes 'directly' into the toner.

For indirect toning, you could dilute this down lots; I'd start by 1+10 or so. Indirect toning is when you bleach the print with a ferricyanide + bromide bleach, and then (after a rinse) put the print into the toning bath. This approach will be much quicker, and only the bleached areas will be toned.

it say that a more toning result is possible with a high dilution

You could use the Photographers' Formulary kit to make a double strength solution by topping it up to 500ml instead of 1000ml.
You can speed up the process would be heating the toner to e.g. 40C; this is also mentioned in the instructions linked to above.

Ensure proper ventilation when using this toner and preferably only use it in rooms where you do not store any unprocessed film or paper.
