Sarana Tile lists Porcelain White as a 10" x 12" glossy porcelain mosaic. It is finished with a gloss glaze that reflects light back into the room. In a home it suits 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 10" x 12", listed metrically as 30x26cm. Each sheet covers roughly 0.84 sq ft. It appears in the Sarana Volume 8 catalogue at page 12. It arrives mesh-mounted, so the spacing holds while the sheet is set and it trims down to meet a corner or a niche. Sarana prices it by the sheet.
