The surface of a tile is distinguished by a number of visual and tactile features, for example:
- a natural surface can be smooth and opaque or with a lightly featured structure;
- a slate-cut (or bush-hammered) surface offers natural rock-like features, such as embossing, sand effects and grooves;
- a honed surface is shiny because it is polished with a mechanical process that does not remove any material;
- a gloss polished surface is even shinier because it is mirror-polished by removing up to 1 mm of the pressed surface.
A glazed surface means the tile is covered by a thin layer of vitreous material that makes it bright and colourful.
