Alcohol Ink. Is the new trend theme from the USA for new fascinating works of art. Here, coloured ink is transformed into delicate watercolour colour gradients with the alcohol-based extender. No previous knowledge is necessary for this handicraft technique. It is suitable for inexperienced as well as for artists. Alcohol Ink is transparent (glazing), adheres to almost all non-absorbent painting surfaces and is smudge- and waterproof after drying.
