patina

Depends on what color of patina you would like to end up with…are you looking for a bluish green, or a dark red/brown or black? There are commercial chemicals available from companies like Art Chemical, but below are some “recipies” you can try…I used the blue-green before….I have not tried the black one…try it on a sample piece first before you commit to it on your hinge so it doesn’t get screwed up.

Blue-green patina
8 oz Ammonia
8 oz White Vinegar
1/8 cup salt

Black
8 oz Ammonia
1/8 cup Liver of Sulfur

You’ll have to make sure the hinge is clean and any protective coating on it is completely removed (e.g. if they used spray laquer to protect it or something else). Mix up the ingredients until they are completely dissolved. You can then spray it on with a spray bottle..you should see the color change pretty fast…then let it dry…

I have a copper/redwood fence I used to keep my dogs out of my grape vines I used copper pipe as the vertical rails. My two male dogs have designated these upright rails as a cool place to urinate and WOW I should market their urine as a patina agent (blue – Green color…. not the color of their urine umm that would be bad lol) Cheap renewable resource….think any one would buy that? Sorry thats the Veterinary humor coming out. Karson’s link is a good one I havent the guts to try and use dog pee for other projects.
