Johnson Endura is a vitrified tile manufactured using special non-ferrous clays, processed and fired at ultra-high temperatures of 1170-1200oc. This process causes the raw materials to fuse and form a Compact mass with low water absorption of less 0.5% resulting in a very strong body (flexural Strength 35N/MM2) with a very hard surface (Mohs'hardness of 7). The surface of the tile is either Matt or textured to provide excellent non-slip property.
