The process for forming simulated marble disclosed in U.S. Pat. No. 3,773,886 is significantly improved by applying the spatter backing composition sequentially in a plurality of superimposed layers, which are respectively graduated stepwise in surface coverage from about 20% coverage in the first, applied directly over the veining composition, up to a total surface coverage of about 80%, except on vertical or steeply sloping surfaces of articles such as bathroom fixtures where the surface coverage is between about 40% and 50%. This results in a rich and variegated depth of field and a muting of the veining and produces a product that more nearly simulates natural marble than is true of the previously patented process.
