The reason marble remains in heavy demand for countertops is its elegant good looks, Marble is heat resistant. In the kitchen, it stands up well to hot pans and pots. In the bathroom, a styling tool won’t mar it unless left on it hot for some time. It’s become popular for fireplace surrounds because it won’t yellow due to the heat and can withstand the occasional spark on its surface. However Marble can and should be sealed when installed and again every few years.
