Abstract: The invention relates to a method for producing an article from agglomerated stone, for example a slab for construction or decoration, comprising the following steps: bringing into contact (i) an inorganic filler, (ii) a polyester resin precursor composition and (iii) a powdered electrically conductive component; mixing same to produce a uniform mass; distributing part of the mass on a substrate; pressing the distributed mass in a vibro-compaction press under vacuum conditions; and hardening the mass by means of polymerisation of the polyester resin.
