Hello,
Is anyone familiar with a process that uses Dichromate + a dairy product instead of Gum Arabic for colored prints? I heard a talk on this last year but forgot the details.
It was either sour cream or cottage cheese treated with ammonia and aged before being combined with dichromate and pigment. I cannot find notes I took.
