I have been experimenting with patinas on metal. You can buy patina chemicals, but you can also use things from around the house, like salt, rust, and ammonia. My feline companion Plumpton and I sometimes collaborate on artistic projects. Here are two examples of copper buried in Plumpton’s litterbox.
Why buy iron oxide when it grows wild everywhere? Yes, iron oxide is another name for rust. Take a rusty object and put in into a plastic bag with a few drops of water and the metal object you want to have a rust patina. Here is a what a steel washer looks like, before and after.
The next items are salt and ammonia and the process is called fuming. I cleaned brass and copper with a wire brush and wiped it clean with alcohol. Then I filled a small jar with white ammonia and put in inside a big jar. I sprinkled salt in the big jar (not in the ammonia), put in the metal, and screwed on the lid.
At first, the brass started turning black from the edges and I didn’t think anything interesting was going to happen.
Here is the same process repeated on copper.
More experiments to follow . . .
A final note – I took “Forming Lasting and Meaningful Attachments” with Robert Dancik last weekend with the Philadelphia Area Polymer Clay Guild last week. The class covers cold connections and is one of the best classes I ever took. I didn’t make a thing, but I don’t care. I learned so much it will take time to process it all. Take this class if you have the chance.
