Abstract

A cast simulated-stone containing flattened globules of overfilled, cured resin, which flattened globules substitute for natural stone chip additives and other such additives. The globules are formed by mixing an excess of a filler with a catalyzed liquid resin composition, the filler being added in an amount sufficient to cause the liquid to break apart into discrete, separable globules of resin composition. The globules are combined with a liquid resin composition and compressed and flattened in forming the simulated-stone.
