    Dry Erasable ink
    What are the materials for making dry erasable ink? I made one with carbon black, isopropanol, resin and a binder. Its writing and removing fine on the board but stains the hand. How do I reduce the stain. Thanks

    Dry erase markers stain hands and clothing. If you can figure out how to make them better, I’m sure you can make good money!
