Staining is also a problem with more porous stones especially darkly colored liquids like red wine.

As previously mentioned granite is of an igneous nature which makes it less porous than sedimentary rocks such as limestone and travertine. Marble like most stone tiles has high maintenance requirements. Porosity and absorbency varies in marble but we are very aware that fluids can be absorbed as marble tops are very easy to stain. Still marble is more porous softer and less durable when compared to granite.

In contrast metamorphic stones like marble and slate have higher porosity because of the re crystallization process. Smooth cool beautiful as a diamond and much more resistant to porosity problems marble is a gem of a counter top surface.
