Well, finally got around to mixing up my kit of Rodinal from Photographers Formulary, which I now see is no longer listed as a product on their website. The directions that were given in the box are incomplete, stopping after page 2 where both A and B are mixed, missing the crucial page 3 & 4. After mixing and figuring out the missing pages, I then added the Hydroxide slowly into the P-aminophenol. Color did change, to that nice Rodinal color. The question I have is the kit was for 250ml, yet the directions called for 156ml H20 in A and 125ml in B, which to me seems like a wee bit more than 250ml!! And that is proved out by the total solution being closer to 300ml, which now has a sort of sludge at the bottom. So, is there a step that I am missing? Should I decant? Any help would be great.
