 Can I use art resin on ceramics? You certainly can use art resin on ceramics, including earthenware, terracotta, a ceramic tile, for example. If your project is three-dimensional, like a terracotta pot, then you'll just want to work in small coats and using a disposable brush to go round and round until it's complete. For everything else that's flat, it's just pour and spread as usual. You may want to try a little test to start out with because sometimes the art resin can make your earthenware or terracotta a little bit of a darker color. So you might want to just make sure that you're comfortable with that color and after that you're good to go.
