Copper Air Plant Containers with Forced Patina

These little copper cups were made in the 1970s and in awesome condition when we found them. They make great little planters for small plants. I did a non-shipwreck forced patina on them to bring out some cool patterns and a range of dark colors. (Some form of teal/cobalt also comes through even without the sea salt, which I do not hate.) I think they look really cool. I put some air plants in them and gave them away as gifts.
