Cultured stone materials, and products including the same, have a plastic component and particulate calcium sulfate filler, which may be a calcium sulfate filler in the form of calcium sulfate dihydrate filler that provides fire retardancy, and the filer provides other processing and product benefits. The cultured stone materials may be made by converting a mixture of a plastic component and particulate calcium sulfate filler to a rigid shaped form. |
