But since I'm here, does anyone use sodium metaborate with pyrocat? I'm used to working with rollo pyro, and I always did a presoak with sodium metaborate, and another post-fix, pre-wash sodium metaborate soak.
The rollo pyro instructions say this post-fix soak is when most of the stain forms (I know nothing of the chemistry involved here).
I didn't get much stain with pyrocat. Is it the lack of sodium metaborate, or just a symptom of the really thin negs?
