-Keramos-
Description & Features
Inspired, as Coante notes, by nature's artistry, Keramos from the Antique series (Essence line) overlays the white with a dense, fine grey texture. Small, curved and curling veins spread across the whole slab, mostly in mid grey, with darker charcoal touches and tiny dark specks, and no dominant direction; the pattern is livelier than a plain white yet remains calm and even from edge to edge. Coante produces its slabs in Muğla, south-west Turkey, with Breton technology: quartz, polyester resin and pigments are vibro-compressed into a compact, non-porous mass, with water absorption below 0.07%, Mohs hardness 7 and abrasion resistance class A4 according to the manufacturer's data. The slabs come in Jumbo (330 × 164 cm) and Medium (310 × 152 cm) sizes, in 15, 20 and 30 mm thicknesses, with a polished or leather finish. It is suited to kitchen and bathroom countertops, islands, splashbacks, stairs and interior floors. It cleans with a damp or microfibre cloth and a neutral cleaner; it needs no sealer or polish, and hot cookware always calls for a trivet.
