Considering the Color and Porosity of Natural Stone vs Composite

The decision to install granite or other natural stone in the home or outdoor area is a big consideration and not one to be taken lightly. Narrowing down the color and pattern of the stone you desire can be a time-consuming, yet important, experience. But, did you know the color of the natural stone can also be a determinant of the porosity of the slab? Porosity is the measure of how much space is open in the rock and the ease with which fluid can move through. The more porous a natural stone is, the more easily it can be stained by acidic and oily substances.

Composed by Nature

The natural design of all natural stones contains some element of porosity. These tiny capillary channels form between the minerals in the stone. As a result, lighter colors are generally softer and more porous. For example, creamy white marble is softer and more porous compared to other natural stones. These characteristics can make the stone easier to stain. Granite, depending on the color and veining of the stone, is always less porous than marble but its porosity will depend on the shade of the stone. Lighter colors are generally more porous than darker colors.

Man-Made Composition

On the opposite end of the spectrum are substances where the composition has been tinkered with to achieve a slightly different look or feel when compared with natural stone. Quartz, a popular and slightly cheaper alternative to granite, does not contain channels between the minerals and does not need to be sealed. Quartz is also a more durable material and is resistant to scratching. Other natural stone alternatives include concrete, wood or wood composite, glass and stainless steel.

Protecting your Choice

No matter if you choose a natural stone or a man-made composite material it’s important to be aware of the best ways to care for the materials and keep them looking like new. If you choose a natural stone, it’s important to stay alert to spills and things left lying on the surfaces. Acidic substances such as coffee, wine, vinegar, tomatoes and citrus fruits and oily substances can quickly penetrate the surface of the natural stone leaving behind a nasty, although unintentional, stain.
