Marble and Granite

Synthetic stone.

Synthetic stone: it's seamless The granite look is beginning to appear in patented stone-like materials. Avonite, made from a modified polyester plastic, now has 14 so-called granite colors. Acrylic-based Corian, manufactured by Du Pont, has just been introduced in two new stone styles. Also new on the market is Nevamar's Fountainhead, with two granite styles. These dense, nonporous surfacing materials offer the peppery, close-grained look associated with some granites, but without as much weight. Surfaces are chemically fused or bonded with special joint adhesives--not grout--so most joint lines disappear. Synthetic stones are resistant to most household stains. Excessive. heat can scorch them. None is appropriate for use as a kitchen cutting surface, though gouges can be patched. For a standard 24-inch-deep counter with 4-inch backsplash, figure from $110 to $125 per running foot, installed. Any additional detailing or edging will cost more. Professional installation is recommended.
