I understand that, for certain alternative processes, ammonium dichromate can be used instead of potassium dichromate but in different amounts. I have about 500g of the stuff sitting in my darkroom that I was given. I don't do alternative stuff so if anyone is interested in it they're welcome to it. please PM me.
