Thanks everyone! Yes I have to remember to think of thiourea as a developer and fix afterward. I would guess that otherwise the print would be pretty darn unstable, like a very poorly fixed untoned print. Is that true, because I haven't heard much about this (including in the directions in the Photo Forumulary's thiourea kit)?
Well, I should qualify that. Presumably you tone to completion and there's no undeveloped halide to worry about. But really you never know if you've actually toned to completion if the toner is near exhaustion or the time in it is too short. I have gone around 1 minute but I understand that with less activator the toning can take much longer. So fixing after thiourea seems like an important arhcival step.
