ABSTRACT:
A realistic three-dimensional replica casting of naturally occurring samples of wood, rock and marine specimens produces realistic appearing landscape or indoor light modules that can simulate flickering candles in nightclubs and restaurants. The method employs a two-part barrier mold technique enabling production of an exact copy of the whole, full bodied, original specimen and includes a lamp unit pattern for creating a three dimensional space for containing a lamp module that is positioned adjacent a relatively flat face of the replica of the natural specimen. The final casting is made of fortified cement that is permanently stained with metallic salts in an HCL solution producing the desired coloration matching that of the original specimen while masking the color of the concrete. The replica is solid and heavy and need not be attached to the ground during outdoor use to maintain it in place, due to the weight of the concrete.
