What is copper patina? It’s that green patina color that shows up on the surface of copper items giving copper an aged look and a rich color.
To create the patina solution, mix together equal parts of white vinegar and table salt so that it coats all of the pennies.
Drain out the mixture but don’t rinse them with clean water.
Place the pennies on a baking sheet and let them dry completely so the oxidation process can complete its magic.
You can add more salt over them as they’re drying if you wish. Pennies will patina at different rates so you can play with the timing to get your desired color.
I decided to glue my pennies to these wooden letters and hang them as decoration!
