Abstract
In a casting composition comprising a curable syrup which contains a liquid monomer and polymer components optionally dissolved therein, and an inorganic filler which includes a quartz sand product, in order to simplify the production of white molded articles, it is proposed that a product, the individual grain of which consists in the core essentially of quartz and at the surface essentially of .alpha.-cristobalite (low-temperature modification) be selected as quartz sand product.
