Abstract
Abstract Cultured onyx, cultured marble, and like mineral-appearing products are provided, as well as intermediates and components and methods therefor through the combination of a locally discontinuous phase comprising a synthetic organic resin portion hardened to a predetermined hardness and a visually distinguishable continuous phase comprising a synthetic organic resin portion separately hardened to the predetermined hardness with the discontinuous phase intimately distributed therein, to form shaped structures having surfaces simulative of onyx, marble, or like naturally occurring mineral in appearance, which surfaces are uniformly polishable in phase undifferentiated relation.
