Yes, marble can be used in a kitchen, but it is important to note that it is a porous and relatively soft material compared to other natural stones like granite or quartzite. This means it can stain and scratch easily if not properly sealed and cared for. Regular maintenance and cleaning is crucial to preserve the beauty and durability of marble countertops. Additionally, acidic substances like lemon juice or vinegar can etch and damage the surface of marble, so it is important to clean up spills immediately and use cutting boards and trivets to protect the surface.
