Iridescent Acrylics may be used alone or with other colors, gels and mediums. "Coarse" colors employ a larger reflective particle size in comparison to "Fine" colors.
The special Mica Flakes, Coarse Alumina, and Micaceous Iron Oxide add a sparkly touch with a distinct texture! These colors are made with assorted mica particles with gel medium. The Micaceous Iron Oxide, with its rich simmer color and gritty surface, makes a glorious ground for pastels. Palette knife application is recommended.
