Sprays smoothing agent on mold and cast prior to pouring material. Pours material from mixing machine into cast on vibrating table, and applies colored mix randomly to material to impart marble appearance to product. Positions sink mold on previously cast product, and applies layers of mix by hand to form sinks. Disassembles mold, using handtools, and places products on racks for curing.
