[pure-silver] Re: Hypo-Alum Toner (Photo-Formulary)

Richard,

Thanks

The Formulary calls for Distilled water (52C/125F) & Sodium thiosulfate,
pentahydrate. Then mixing in Potassium alum (alum), with the Silver Nitrate
& Potassium Iodide as options to be added after. (I didn't include amounts
deliberately - I don't believe I have licence to publish their formula).

But the document doesn't mention that sulfurization is required.

Regards Dave

I think the milky appearance is normal.  I don't know 
about Photographer's Formulary toner but here is a typical 
formula: Agfa/Ansco 222
