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 water, oil, or dirt. Conversely,
glazed tiles usually have a shiny 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 come in a larger variety of colors and styles than unglazed and are more stain-resistant.
