Oxidizing a copper table top

I have a new coffee table with a copper top. It is oxidized and has a nice patina finish. The dark marks that appear on the table from liquids, etc. just add to the patina. The problem is that there are really bright shiny copper areas where something has removed the patina. Is there any natural substance I can apply to darken them?

One of our readers suggests a crumbled hard boiled egg. Cover the spot generously, cover with a taped down sheet of plastic, and let us know what happened.
