A ceramic floor tile comprising:
- a substrate;
- and
- a surface coating provided on an upper surface of the substrate, the surface coating comprising:
- a base formula comprising a glaze;
- and
- solid particles comprising tabular alumina,
- wherein the base formula and the particles remain separate after firing,
- wherein the particles make up from 1 to 7% of the surface coating weight after firing,
- wherein about 50% of the particles have a diameter less than 7.25089 μm, and
- wherein the surface coating provides a clean-ability ΔE of 0.6 to 1.0 and a dynamic coefficient of friction of 0.60 to 0.95.
