This is a supplement to my preveious posting on this subject.
Making the coating-
Mix 1 oz.(30 ml) of instant powdered milk with 7 oz.(199 cc) HOT
water. Stir well. Add a few drops of 28% Acetic Acid or Lemon juice
to curdle the milk.
Strain the curds through cheese cloth and wah the curds in cold
water.
correction wash the curds in cold water
Crumble the curds into a beaker and add 2 oz.(50 cc) of 1 %
ammonia and mix well.
Mix 1/2 teasp.(2 1/2 ml) of casein soln.(curd mix) with 1/2 teaspn.
of Dichromate soln and 1/4 teaspn.(1 1/4 ml) of watercolor pigment.
Development-
Place the exposed paper face down in a tray of cold water for
5 min. Then transfer to a tray of 2 oz.(57 ml) of 1 % ammonia and
32 oz.(909 ml) of cool water for 5 min. Keep moving the print back
and forth between the two trays until the highlights of the coating
disolve. Wash in plain water, dry and stand back and admire your
results.
Once again, its been a while since I made a milk print, but as I
recall at the time I had a terrible time explaining to people how
you could make a photograph from milk. Also, no one answered my
question so I will repeat it.
If you use chocolate milk, will you get a sepia toned milk print?
