Sk Cronos Marfil is a 9" x 13" porcelain tile from Sarana Tile. Residentially it works in kitchens, entry foyers and open-plan living areas. Commercially it is specified for retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 9" x 13", listed metrically as 22.5x32.5cm. It appears in the Sarana Volume 8 catalogue at page 163. Porcelain is pressed and fired dense enough to take water and traffic that a wall-grade ceramic could not.
