Understanding how the janka hardness scale works is simple. It does not measure the fracture strength of the entire tile nor does it offer any rating of the slip resistance of the tile. Mohs hardness scale is applied to flooring tiles to show how hard their surface is. Tiles are vitrified i e.

This hardness scale as with many hardness scales is a relative measure and doesn t give the entire picture of how durable the material being measured is.
