Copper is one of them. The fishscale copper walls I designed for the exterior of this Missouri home are aging very slowly, but beautifully. This is the interim character we were hoping for while the copper develops its characteristic, coveted green patina.
Since the 1970’s we have seen a significant reduction of acid rain. Now, copper takes forever to patina (darnit!). I won’t be lobbying to bring back the pollution… probably, but, I still hope the green patina develops in my lifetime. Thankfully, copper is beautiful during all stages of its life.
The installers of these copper panels, with their white, cotton gloves, were akin to surgeons as they delicately installed them. I suspect even atomic bomb technicians don’t handle their charges with such reverence. After all, an explosion is a one-time occurrence, but fingerprints left on copper, that’s forever.
