Hi, Erin. Sorry for the delay in answering your question. Paint would prevent the oils from being absorbed into the clay, so the scent would not last. Pieces could be partially decorated with paint, leaving some open clay areas where the oils could be applied and absorbed. Hope this helps.
Thank you so much for all these wonderful activities and ideas. I used to spend hours compiling quizzes and looking for activities. You have made my job so much easier, keep up the good work!! :)
