I have checked in the seach, for oxidation of copper, turning copper green ect. and can not find anything. I know I have seen it on here before. I wanted to know, ( other than leaving it outside for a while) how to turn copper wire, thin sheeting, ect to the green color it gets when it oxidizes. Thanks, rw

pee on it. For real.
Randall, you might try looking in Home Decorating and Paint stores.I have seen several on the market that go with metal effects paints.Its part of a system of metalic paints they use for decorating.First you apply the paint made with metalic particles whether it be iron,copper,brass, etc,then you let it dry.If you want a aged or weathered look you go over the top of it with the patina.It reacts with the metalic particles in the paint so I don't know why it wouldn't work with pure metal.Of course I would do a test area first.I just went to a product show and they had some there.They had a piece of cardboard shaped like angled iron that was painted and aged with this stuff.As I walked up to the booth a person in the booth through it at me.It totally caught me off guard,I thought I was in trouble for a moment till I realized it was cardboard.Martin.
My uncle just finished up his house about three weeks ago and the copper flashing is already starting to take on a old weathered look.
I think that is due to the humidity of the deep south.
Hope that helps.

I vote for urine. Andy Warhol had a bunch of people pee on copper plates and instantly they turned green. He then sold them for thousands.
You could use the patina that is used in stained glass shops. I believe Research sells it also

try calcium carbonate. mix with a little water to make a paste and spread it on. try a small area first. if that does't work, pi$$ on it, let's go fishing. he he
The urine thing does work because it has the two componensts required for rapid oxidization of copper. Simply mix a good salt water solution and it will oxidize very rapidly.
This is also the reason why places near seashores experience more oxidization of metals than inland areas.
Hope that helps =)
is used in theater/stage work to quickly oxidize wires and metal sheeting used in scenery. Simply wipe on with a clean cloth. The goal being to get the desired look both quickly and cheaply, a bottle of RealLemon from your local market only costs a buck or 2, and is much less offensive to work with than chemicals or bodily fluids.
I recommend the following book:
THe Colouring, Bronzing And Patination of Metals
Authors: Richard Hughes ans Michael Rowe
Editor: CRAFTSCONCIL (4TH EDITION 1989)
ISBN 0 903798 60 3
Good luck

Take ammonia outside and put it in a pot on a hotplate. Then just put the metal over the vapors will oxodise it. You can also add bleach to the mixture, but then you MUST not inhale anything as it will release chlorine bleach, and it can kill you! Will work faster though!

I;ve been in the water field for 12 years and have never come across an encounter where someone has been killed from cl2 vapors. Now yes it will scar the lungs extremely But if i;m not mistaken there is no known cause of death resulting in cl2 vapors being inhaled but who the hell am I. be careful best of luck.
