etchings - trees and shadows





 sketch of trees and shadows - late afternoon long shadows and winter trees

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.
