Third, pay attention to the marking of tiles. For example, if the product has a marking on which a foot is depicted on a dark background, then this is a floor tile. If the foot is black on a light background, then this will indicate that the product has increased wear resistance. When there is an image of the hand on the marking, this suggests that the tile is intended only for wall cladding. If there is a symbol with a flame, then this means that the product has passed the processing of firing technology. If there is a symbol in the form of a snowflake — this will mean increased frost resistance of the tile.
