Granite is a very hard substance and is not susceptible to scratches. While not ideal to work on because it will dull knife blades, it will take normal wear and tear very well. Granite resists heat too, so its use near a range or cook-top is ideal. When you have to set down a hot pan fast, granite can take the heat without being damaged or weakened. In the bathroom, placing a hair tool on it that is still warm won’t be a problem.
