Marble Countertops

Putting marble countertops in your kitchen is one way to simultaneously enhance the appearance of your kitchen and increase the value of your home. Marble is comprised of calcite, and it is a result of the metamorphosis of limestone.


How Marble Is Created

Limestone is a sedimentary stone that is formed by the settlement of shells and bones of sea creatures on the ocean floor. Both limestone and marble are formed when the calcium from the shells and bones combines with the carbon dioxide in the water. Calcium carbonate forms from this combination and it is this substance that is the basis of all marble. Under heat and pressure the limestone will crystallize and transform into marble. The heat and pressure that is necessary to transform limestone to marble is intense enough to destroy any of the shells or bones that existed in the limestone leaving the marble free of these materials.

Different Uses for Marble

The resultant marble is a smooth stone that is capable of taking a polish. In kitchens the most popular use for marble is countertops but it can also be used on islands, backsplashes, and as accessories such as cutting boards or salt and pepper shakers.

The Color of Marble

If you think the only decision that you have to make when you opt for marble countertops is whether you would like a solid slab or tiles, you are mistaken. There are many different types of marble available and choosing one can seem quite overwhelming. One of the most obvious differences that you will notice when viewing different types of marble is the different colors that are available. Some of the most popular colors of marble include black, blue, red and grey but marble can be found in just about every color of the rainbow. The color of the marble indicates the presence of other natural elements when the marble was formed. For example the presence of iron results in reddish, brown colored marble while the presence of magnesium results in marble with a greenish hue.

The Veining of Marble

The veining of the marble also affects the appearance. Although this is usually only a small portion of the entire stone, it can have a significant impact on the appearance of the stone. Whether you like more or less veining is largely a matter of personal preference.

The Edges of Marble

The edge of the marble is another difference to consider. Marble can be edged in a variety of ways. Some of the popular choices include a bevel, a half bull nose, and a bull nose. There are many other options available, and different manufacturers may offer custom options as well as the standard edges.
