Abstract

Embodiments of the present invention combine an open-face molding process and an injection molding process to embed decorative articles within a shaped unitary body. Two half-molds are formed, each serving both as an open-face mold alone and as components of a two-part mold in combination. An open-face molding process is performed in iterations using each half-mold, wherein during each iteration a layer of a fluid thermoset is poured into each half-mold and allowed to harden into a solid body; pits are bored into each solid body and decorative objects deposited therein; and each pit is plugged with additional quantities of fluid thermoset. Subsequent iterations may be performed over already-formed layers within each half mold. Finally, the half-molds are closed together and joined by an injection molding process, forming a unitary body having a plurality of decorative objects embedded therein.
