Liquitex Heavy Body Artist Color, previously referred to as High Viscosity, has a thick consistency for traditional art techniques using brushes or knives, as well as for experimental, mixed media, collage and printmaking applications. Impasto applications retain crisp brush stroke and knife marks. Good surface drag provides excellent handling and blending characteristics with increased open-working time. High pigment load produces rich, brilliant, permanent color. Exceptionally smooth, thick buttery consistency retains brush strokes and palette knife marks. Remains flexible when dry so that thick films stay free of cracks and chips.
