Porcelain is an 8" x 8" matte porcelain mosaic from Sarana Tile. Sarana supplies it with a matte face that holds light rather than throwing it back. On the residential side that covers kitchens, entry foyers and open-plan living areas. It also carries commercial use in retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 8" x 8", listed metrically as 20.6x21cm. Each sheet covers roughly 0.81 sq ft. Sarana catalogues it in Volume 8 on page 7. 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.
