  • Coated particle with shimmering appearance and engineered stone containing coated particles
    Publication number: 20090274909
    Abstract: A coated particle having a shimmering appearance to an observer contains a refractive particle, a transparent coating on the refractive particle, reflective particles and refractive particles embedded in the coating, with one of the reflective particles or the reflective particles primarily at a surface of the coating. Also an engineered stone has a shimmering appearance due to incorporation of coated particles.
