Colour alcohol-based with liquid consistency. It is clear and unmistakable for its brilliant shades. Its suitable for all surfaces, but its features are enhanced when applied on smooth surfaces like glass, ceramic, resin and metal glazed. On porous surfaces remains transparent but loses its brightness. Can be used as normal colour to be applied with a brush or with the dropper included. Since the colours are very liquid they will work together mixing more or less homogeneously depending on the surface and the effect you create moving the object or helping the colour with brushes or sponge-brush. To clean the brushes you need to use the supplied Thinner for Colorink. A surface decorated with Colorink is further enhanced if finished with a gloss or glaze finish.
