ABSTRACT:
The conventional process for forming a simulated ornamental stone is improved by using alumina trihydrate as a filler for a polyester or the like resin with catalyzer for depth-simulation, the same being applied as a substantially integral translucent layer of variegated depth substantially coextensive with the superficial veining surface of the product and being backed by a solidly colored material which may include a solidly colored gel coat between the depth-simulating material and back-up matrix material.
