[TheForge] copper patina

[Bruce Freeman]

Clean the copper to bright (not necessarily shiny) with vinegar and salt
(and detergent if greasy), then leave it damp in the open air.

I know we have been here before but cant seem to find my notes on it. 
 
Can anyone recommend a technique for putting an aged patina on copper? 

Looking more for the brownish, rust color of an old penny rather than 
verdigris. 
Any ideas much appreciated. 
 
Re last weeks question regarding forging copper I have found the more
pure  
the copper the better to forge. I annealed at a just red heat and
cooled in  
water for the thinner stock. Heavier stock worked great from low red to
cool and 
 hard to shape. 
 
Kindest thanks
Don Plummer
