Matte and glossy ceramic tiles differ in their glaze, glass-forming minerals and ceramic stains that range from satiny to shiny. These glazes help protect the tiles from stains and moisture, but matte and semi- or high-gloss tiles have varying characteristics in the areas of surface adhesion, scratch resistance and dirt visibility. Although a certain type of glaze won’t prevent you from using the tile as you wish — whether installing it in on floors, walls, countertops or other areas — having a thorough understanding of each glaze’s characteristics helps you use ceramic tile more effectively.
