I then used diluted coffee and painted an image (based on this sketch) onto a piece of aluminium plate. I rolled Baldwin's 'Big Ground' over the top and baked it all in the oven. Then I put the plate in warm water and rubbed away the ground which was onto of the coffee. See below...
The image revealed on the plate!
Then I placed the plate in a mordant to etch the image into the metal. See here some plates in the copper sulphate saline solution...
Then I inked up and printed the plates using my etching press.
