chemical solutions:
solution A: potassium ferricyanide 10g + 100ml distilled water
solution B: ferric ammonium citrate 25g + 100m distilled water
Mix equal parts of solutions A+B when you are ready to use it. It's best to store the solutions in separate brown bottles. Keep chemicals in dry form until you need to make up the solutions.
