Ceraforge Iron is a 2" x 2" matte porcelain mosaic in the Ceraforge range. The surface carries a matte face that absorbs light rather than bouncing it. Shade variation is graded V3, a moderate spread of tone that gives the floor real movement piece to piece. In a home it suits kitchens, entry halls and main-floor living areas. On commercial jobs it turns up in retail floors, restaurant and cafe dining rooms and hotel lobbies. The published figures are a DCOF of 0.50, at or above the 0.42 threshold ANSI sets for level interior floors expected to be walked on wet, Class 4 abrasion resistance and Mohs hardness 6. The edges are rectified, cut square after firing, so it sets with a joint of roughly 2 to 3 mm on a flat substrate. The body is color body porcelain.
