Fast drying water resistant and transparent drawing inks from Winsor & Newton favoured by designers calligraphers artists and illustrators. Drawing inks can be applied with a brush dip pen or airbrush. The 26 colours include Liquid Indian Ink (which is non-waterproof); a water based solution of traditional Chinese stick ink. This is the standard lettering ink used by calligraphers. Formulated from a series of soluble dyes in a shellac solution our drawing inks offer unrivaled strength and colour brilliance. The drawing inks allow overlaying of different colours for attractive colour mixes. All the colours are water resistant except Liquid Indian Ink Gold and Silver. All colours are intermixable. Gold and Silver should be added to other inks in small quantities to avoid thickening. Mixtures of Gold and Silver should not be stored together due to adverse chemical reaction. 14ml bottles. 26 colours.
