Abstract
Abstract A tile product is disclosed which comprises a ceramic substrate having opposed major surfaces, a layer of natural stone and an adhesive bonding the layer of natural stone to one of the major surfaces of the ceramic substrate. The layer of natural stone preferably comprises a plurality of strips made of fossilstone and the substrate is preferably made of an unglazed ceramic bisque. A method for producing a laminated tile product includes providing a ceramic substrate having opposed first and second major surfaces; providing a layer of natural stone having opposed first and second major surfaces; providing an adhesive material on at least one of the first major surface of the substrate and the first major surface of the layer of natural stone; assembling the ceramic substrate and the layer of natural stone so that the first major surface of the ceramic substrate faces the first major surface of the layer of natural stone with the adhesive material therebetween; and polishing the second major surface of the layer of natural stone. The polishing of the second major surface of the layer of natural stone preferably causes heat which bonds the layer of natural stone to the substrate. A plurality of the laminated tiles of the present invention are installed by providing an installation surface, selecting an adhesive; coating the installation surface with the adhesive; and applying said plurality of laminated tiles to the adhesive.
