A non-catalyzed mixture of polyester resin and filler, in the proper proportions for use in the manufacture of cast resin articles such as cultured marble, is vacuum-packed into a novel airtight shipping and dispensing container. A container typically contains two to five hundred pounds of the resin/filler mixture. Rather than supplying resin and filler starting materials to fabricators as separate materials, the resin and filler starting materials are supplied in a pre-mixed condition in the airtight containers. In one embodiment, a fabricator uses a novel dispensing and mixing machine to extract a desired amount of non-catalyzed resin and filler mix from a container. The machine mixes a catalyst into the extracted mixture and the resulting catalyzed mixture is output from the machine. Efficiencies in the distribution and transport of the starting materials can be realized. Inventory control can be simplified. Quality and uniformity of the resulting cast articles is facilitated.
