Magic ink becomes transparent or disappears when it gets hot! The heat from the hot coffee or tea warms up the ceramic mug, and causes the Magic ink to change from an opaque black to clear, revealing anything printed behind it. When the mug cools back to room temperature, the ink becomes opaque once again. Four color process printing on an 11oz. ceramic mug.
