Do you remember stamp printing onto paper as a child? Now you can do it on glass. Color Line Paints & Pens will work with any rubber stamp, linoleum cutting or a hand carved potato stamp. For sharp line definition and homogenously printed surfaces use Silk Screen Paste (the denser and pasty form used for screen printing). Use a brayer to transfer the paint to the stamp and make sure all high points are covered.
The density of the paint will leave a strong and clearly defined image on the glass.
