I have made my own sepia toner and bleach using forumlas I got off of this
list and I am very happy with the results. What I would like to know is
what is the shelf life of the stock solution. The Potasium
Bromide/Potasium Feericyanide solution and the Thiocarbimide solution.

Also, is it a good idea to mix a fresh working solution each time I use it
or can I store that for a while too.

I would be addressing this to the person that gave me this great info but I
am at work and that email is on my system at home.

Best Regards,
