Abstract

Artificial stone which exhibits minimal visual change when exposed to weathering, UV light, and heat, is prepared by shaping and curing a crosslinkable composition based on crosslinkable organopolysiloxanes as a binder, at least 85% by weight of a filler component, the filler component containing at least 20% by weight of coarse grain mineral filler having grain sizes of 0.2 mm to 10 mm.
