File And Degrease

10 Oct

a file

Take a sheet of warm, shiny copper. File the edges, first with a coarse file, then two successively finer ones to make a gently bevelled edge. Smooth the corners so they are slightly rounded. Flip the sheet over and gently remove the burr around the back edge with the finest file.

b degrease

Then take the copper sheet to the sink and spritz it with soy sauce. Dip a sponge into French chalk and rub it all over the sheet, working the soy and chalk into a paste, making circular patterns in gentle salmon pink until the plate is completely degreased. This afternoon at Swansea Print Workshop.
