I've only used the paper clay to stamp directly into. I used acrylic paint to color it (kneeded it in), and stamped into it with craft ink, it's the only kind I have. It came with a website that had instructions on it about how to "cure" it, either by air drying it or the time/temp to bake it in the oven. Does your package have a website on it? Sorry I can't help more!!! Good luck, and let us know what you find that works!
