Now!!! this is a challenge that is right up my artistic alley!! I work with rust in all of my art works, using a solution technique that changes the face of paper and cloth and any other stuff that you would like to dip into the solutions!
I have set out the 'recipe' here... free for all to experiment with and to use.... just a thanks on-line would be appreciated, after you have tried it!
Whilst you are on the page to get the rust recipe, have a look at the "Works on Paper" and you can see just how I have used the rust solution for these exhibiton pieces.
Have fun as I have had over the last 20 years using this non complicated way of getting 'rust'!!
The art work here is a book made from rusted paper, sticks that also went through the rust bath and leaves... all placed into a box that I constructed from 'foam core board' then dipped into the solution.... you never know what you are going to get!
