Whats the best way to age copper?
I built a 20in diameter X 36in high Dovecote last year and put a copper roof on it. My ambition is for the green patina but I want it sooner than later. I have looked around over here for some form of accelerant but it is not readily available in small qtys. I'd have to pay Â100 for a 5gal drum! The dovecote only cost about Â25 to make in the first place!!!
The roof is about the color of an old penny now.
Is there a home made, old world recipe to help the "greening" along or do I have to wait 5 10 yrs for the required effect?
I have noticed though, some traces are turning green but mainly around where bird droppings have been left behind by the occupants. If I made up a soup from nitrogen fertiliser and sprayed it on, I wonder would it do something??
Or would I be better off buffing up the copper to high sheen again and laquer it???
