Wall tiles are typically made from crushed, dry clay mixed with water. This creates a liquid that is poured into molds. After the mold dries a thin glaze is applied and the tile is fired at very high temperatures. Wall tiles are always glazed creating a very slick surface. These are usually put on the wall but often put on the floor too. They can become ice rinks when wet. See below for our recommended product to increase traction on wall tiles.
