About 20 years ago, I baught 4 copper porch lights. Next I whent to a hobby shop and baught a bottle of copper patina liquid. Next I took out the glass and applied the liquid with a small cloth and within a day I got the really nice copper patina in a mutitude of shades . Then I rinsed them very well with water. Now they are in our Cal. house as wall sconses in the dining room. You can also apply flux ( used by plumbers to clean the copper when soldering onto the copper . This takes much longer but will turn color eventually.
