Mosaic tiles have been used in ancient kitchens to create colorful and intricate backsplashes. These small tiles, made from materials such as glass, ceramic, or stone, are arranged in patterns or pictures to add a vibrant and artistic touch to the kitchen. The ancient Romans were known for their elaborate mosaic designs, often depicting scenes from mythology or nature. Mosaic tiles not only added color to the kitchen but also provided a durable and easy-to-clean surface.
