Hi
I have been given an old brown bottle labeled 'Amidol' it contains about 100 grams of small black crystals which may have a slight red tinge to them, can anyone advise if these really are Amidol and if so could they be used to make up some print developer, all the info I can fin on the internet describe Amidol as a fine white powder.
Any help would be greatly appreciated
Tony
