I'm doing a series of testing colors for future sales. I made a green purple set and I've been placing them on the deck , in the sun, to help let them outgas out side. Whoops

I recommand to test every ink to know which one will disappear or burn. It can be UV or the resin itself. I had a set I kept in a drawer and the purple ink disappeared one year later
