Have you ever painted with Alcohol Inks?
They are a relatively new art medium that is very vibrant and fluid. Use them on non porous surfaces like Yupo paper, glass, ceramic tile and metal. In this experiment with Alcohol Ink I painted on a 6 inch by 6 inch ceramic tile. The great thing is that if I don't like what I have created, I can just spray the tile with rubbing alcohol and wipe it off.
