I followed your link. I was expecting to find some engraving or irregular surface roughness, but no. To me, what I saw is just a beautiful and artistic coloring job by use of different inks, varnishes or chemical patinas over copper combined by brushing, dripping or perhaps incompletely mixing colors to obtain the effect. In any case, if you are curious about other surface finishing methods used to mimic natural materials, consider the plastic interiors in your car. These parts are produced in steel moulds which have their internal surfaces carved with the same pattern on reverse, to give the plastic the exact roughness and grain orientation of natural leathers, geometric designs, etc. The process used is called mold texturing and involves photoetching and selective acid attack artistically combined over the steel surfaces.
