Unglazed tiles are more slip- scratch-resistant than glazed tiles, offering a less shiny, often matte appearance. Typically, unglazed ones are more porous, making them more susceptible to absorbing oil, water, or dirt. Conversely,
glazed tiles usually have a glossy finish, although it's worth noting that they can also be found with a matte glaze. The glossy finish is achieved by applying an additional layer of liquid glass to the surface. Glazed tiles also are more stain-resistant than unglazed and come in a larger variety of colors and styles.
