Hi Sara...(excuse me while I laugh again about the "Lime Hat Cat")...okay I'm back, and I would suggest you just leave that copper alone...the ugly pastel green in final stages will last a century...the beautiful deep red brown will begin to occur (depending on climate) within a years or so...what look/colour/patina are you trying to create?

Hi there! Does anyone happen to know the recipe for an eco-friendly copper patina? I'm installing copper in a building and would love to play with visual texture patinas offer but really don't want to mess with all the chemicals.
