ABSTRACT:
A filler composition for mixing with a resin to form a castable marble-like product comprises an inorganic filler material, such as calcium carbonate in powdered form admixed with components which considerably reduce the density of the cast product. The weight reducing components may be hollow ceramic spheres in combination with hollow plastic spheres. The plastic spheres have an average diameter significantly less than the average diameter of the ceramic spheres. The plastic spheres act as cushion to minimize break up and degradation of the ceramic spheres. When the filler composition is admixed with a resin, the resultant cast product is considerably lighter than existing cast marble-like products.
