Sarana Tile lists Alexander Pormos as a 12" x 12" matte porcelain mosaic. It is finished 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 12" x 12", listed metrically as 30.6x30.6cm. Each sheet covers roughly 1 sq ft. It appears in the Sarana Volume 8 catalogue at page 8. 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.
