Difference Between Marble and Granite

When it comes to deciding on kitchen countertops, granite and marble are the first two materials that come to mind, perhaps because they are the two most popular options. Difference Between Marble and Granite

Despite being very good materials for this particular use, the truth is that both are susceptible to some stains and scratches over time. Now, it is good that you understand the difference between them because each one has particular characteristics that you need to know in order to choose the alternative that suits you best.

GRANITE Difference Between Marble and Granite

Physically the appearance of granite is very different from that of marble. This one is mottled, that is to say that it seems that it has many colored freckles; this due to the various stones (feldspar, quartz and biotite mica) embedded in it.

It generally comes in darker colors than marble and is also harder and more resistant. Likewise, granite is also brighter.

Due to its greater resistance, granite is used more frequently than marble; both for kitchen countertops and also for floors.

Note:  some types of granite can contain elements of a radioactive nature, such as radium, uranium and thorium. Over time these elements can break down and emit a noble gas called radon, which can cause cancer if found in high levels.

MARBLE

On the other hand, marble looks more delicate than granite. It is generally found in lighter colors such as grayish white, cream, or white with dark veins. There are other varieties in greenish and pinkish colors, but these are quite rare.

Marble, like granite, is porous but is less resistant than the latter and stains and scratches are more visible on its surface. It is made up of mineral impurities such as silt and iron oxides.

Unlike granite (which is shiny), the finish of marble is matte and takes on an appearance of softness and delicacy; but currently a special varnish is sold to give it shine.

Marble is especially susceptible to heat and acids, for this reason its use is more limited to the bathroom and other less frequented places in the house; not so much in the kitchen.

With the passage of time, the marble inevitably becomes duller; But if it is well maintained this process can be delayed much longer.
