Dala Alcohol inks can be used any hard, non-porous surface such as glass, plastic, ceramics and stone.
They are waterproof but can be cleaned and re-wet with alcohol allowing you to create different effects. When the Dala Alcohol Ink is applied, the alcohol evaporates, leaving the dye behind the way you want it. They dry fast and because of the high pigmentation they give you a dense colour finish.
