Marble

Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO3) or dolomite (CaMg(CO3)2)) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not foliated (layered), although there are exceptions.

As a floor material, marble is easy to scratch. You can first use a vacuum cleaner to suck away the grit and dust on the marble floor, and then use a steam cleaner to remove other dirt.
