Optimal fiber paper fixer for Thiourea to completion as only toning?

[Juan Valdenebro]

Hello,
Papers are Ilford Galerie & MGWT, and Foma Fomatone. All of them developed with Agfa Neutol WA (Ilford ID-78 / Rollei Print WA).
Thanks.

I'd say most fixers sold commercially will work with these three papers. If the fixer is a rapid fixer, i.e. Ammonium Thiosulfate based, you will get reduced fixing times and as a result faster washing. In the same fashion a neutral or alkaline fixer will wash out quicker.

An extra long wash before fixing seems to be a good thing ( to remove as much thiourea as possible before fixing ). The washing itself releases a little H2S, I like to do it outside. It's an interesting question whether fixing is actually needed after toning to completion, seems like there would be no silver salts left....

Thiourea will actually support fixation speed, see Rowland Mowrey's Superfix I recipe.
