I recently mixed up a batch of Pyrocat HD ‘A’ and ‘B’ solutions. I got the ‘A’ solution right but not the ‘B’. I ended up with a lot of potassium carbonate that would not dissolve settle out in the bottom. Ya I’ve got to check my scales when weighing out larger quantities. It’s an older Mettler and it works great up to 10g. So any way now I have a saturated solution of potassium carbonate instead of 75g to 100ml of distilled water. The sheets that I’ve developed in 2:2:100 my normal ratio, have come out fogged. They are not stained in the outside edges they just have reduced silver, that I can see. I’ve tried a 2:1:100 solution and got reduced fog, but it was still present. After that long explanation my question is does any one know what a saturated of potassium carbonate is?
E.G. Xg. of potassium carbonate to 100ml. distilled water.
I'm looking to figure out what ratio of A to B to use.
