The bleach is a potassium ferricyanide bleach from a Kodak Sepia II package. I dilute my bleach because I find that at full strength it acts too quickly. I can't control the degree of bleaching. Now that I think about it, the bleach probably is older than the toner. I would have mixed the bleach when I was doing some sepia toning well before my trials with polysulfide toning.
I don't know if the toner has oxidized. Any ideas what it would look like? I know if it is exhausted, it will turn cloudy. Mine is a little dirty from use, but not cloudy.
