   actually doesn't have to come from a horse. i found this out researching the technique for a copper cap on a shed. i read that old time copper roofers used to "christen" their roofs at the end of the job (after the celebratory beers, i guess). good luck. rich.

   *Specifically, I always heard that is was supposed to be urine from a pregnant mare. If you don't like the sound of this idea I think Berger Bros. roofing sells pre-patinated copper, at a price.

   I've used a product called 'patina green' on smaller projects like aging a copper trellis. You just brush it on with a stiff brush and let it dry, can do a second appl if you want more color. Contains ammonium chloride and copper sulfate. 16 oz bottle says it covers 30 sq feet with two coats. You can pick this up at a craft store.

   A friend of mine is planning some rehab work on his house which has some copper details. He's located a place that can sell him replacement pieces but wants to try and match the patina of the existing copper rather then let it age naturally. I thought I remembered reading somewhere of a chemical you could treat the copper with that would cause it to get it's green patina much faster. Is anyone familiar with this process?
