ABSTRACT:
An apparatus for making multi-sectioned and multi-colored products having a predetermined geometric or other shape from different slurry mixtures requires a carrier with a predetermined sized and shaped peripheral wall optionally used with a flat or a contoured support surface, the carrier has; a latticed grid formed by intersecting and interconnected members which define random openings, and at least one or more dividing blade slots so connected in the carrier that the latticed grid is divided into spaced slurry receiving sections, and dividing blades adapted to be removably positioned and repositioned in said dividing blade slots provide means for alternatively and selectively isolating the respective spaced slurry receiving sections so that different slurry mixtures can be poured into each of the isolated spaced slurry receiving sections to harden therein about the carrier to form a furnished integral product.
