Mostly I start with a lot of vinegar after that salty water. Every now and then a
splash from the bottles that accumulate under the kitchen or darkroom sink, old
developer, soda, a leftover from cyanotype etc. Sanding down parts that are to
strong can give a dark grey in light grey image. To prevent parts from oxidation I
put vaseline on the plates.
Most colour though comes from a thin layer of copper that I apply on the steel.
Poor vinegar over degreased plates then on that apply a strong solution of
CopperNitrate. Copper can easily be turned in all kind of coloured salts. If you
want to try on pure copper, go to an electronic shop for print boards. An excelent
guide to patination with numerous receipes is:
