Daler-Rowney FW Pearlescent inks are a unique range of water-based acrylic colours producing a shimmering pearl effect. This ink is water-soluble when wet but dry to a water resistant film. All colours are intermixable and rate good to extremely lightfast. They are permanent and translucent but work best when put down freely rather than applying successive layers of colour. The shimmering pearl effect created by these colours is startling and offers almost unlimited creative potential in areas not normally associated with inks and will work on wood, leather, glass, ceramics as well as paper and board. Please note that pigments are large in particle size so are not suitable for fine line nozzles for airbrushes or technical or fountain pens. FW Pearlescent inks are best applied using a dip pen, ruling pen or brush.
