Water-soluble graphite powder ArtGraf. Extremely versatile, Viarco’s ArtGraf water-soluble graphite powder gives the artist the opportunity to explore new techniques and approaches with one of the oldest and most conventional raw materials used in fine arts Naturally able to make the traditional shade, it has the advantage of allowing to work with water before, during or after application. With soluble and fixing properties incorporated into the formula, the ArtGraf graphite powder provides a rigorous control of the scale of greys, from transparent to the opaque only by controlling the proportion of water and graphite. Challenging, it can also be mixed with other water-based paint materials, providing the experimental freedom to create new colours, shades and unique textures.
