Abstract
The invention relates to high filler content plastic molded articles, which articles have a surface having a pronounced glitter appearance resembling that of a microcrystalline mineral material. The glitter effect is obtained by incorporating glitter-producing particles having a plastic basis and a specific gravity <2, in the composition of said articles. A method of manufacturing such molded articles is described, according to which all of the components are adjusted to corresponding densities. The products have a particularly durable simulated-rock appearance with good glitter characteristics.
