Soy Milk as a Mordant

I have learnt a lot about the use of soy milk as a fixative and as a mordant during my study of earth pigments. Primarily to use soy you must use fresh soy milk that has been made that day from beans soaked overnight and blended with water prior to use.

I had tried soy milk as a mordant in earlier eco dying attempts but never been very successful. That was because I tried to use off the shelf store bought soy milk. So i decided to give this ago.

The example above was made using scoured cotton and soaking the cotton in fresh soy milk for about 30 minutes before making a bundle and steaming it. I omitted to give this fabric a tannin bath before using it so the liquidamabar leaves have not printed well but the maple, cotinus and forest tulip leaves have all transferred successfully. The cotinus leaves were fresh but the others were taken out of my freezer and rehydrated before use. I think a tannin dip would have further enhanced all the prints.
