Alexander Glass Leaf Light Grey is an 11.7" x 12.4" matte glass mosaic from Sarana Tile. It is finished with a matte face that holds light rather than throwing it back. Residentially it works in kitchens, entry foyers and open-plan living areas. The nominal size is 11.7" x 12.4", listed metrically as 31.5x29.7cm. Each sheet covers roughly 1 sq ft. Sarana catalogues it in Volume 8 on page 10. 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.
