hello. I just finished a 5.5 kilo batch of assorted pins and other electroplated material, and have left my sulfuric acid sitting for over a week in order to separate black slime and save the acid for a later run. I read the tutorial which shows pictures of relatively clear liquid above black mud, to be decanted, but this won't happen for me. I have a jar full of opaquely black solution that hasn't cleared at all. I wonder what's going on and what to do next. There appears to be some accumulation at the bottom of my tall glass container, but I'm not sure since everything is so densely black. I guess my next step would be filtering in a fiberglass "charmin" plug but...
I wonder why the acid is still so black. :mrgreen:
thanks,
