The Italian company Bisazza is specialised in the manufacturing of glass mosaic tiles. The range of designs which are prefixed on nets of 30x30cm covers rather simple uni-colours, mosaic patterns and images made by designers like Alessandro Mendini, Marcel Wanders and Carlo dal Bianco. They also design objects covered with the Bisazza tiles: from lamps by Mendini to a car by Wanders. Custom made pixel patterns based on digital images for example, are also possible.

The Opus Romana tile is smaller and thicker than the other glass tiles of Bisazza. Unlike these ordinary tiles the Opus Romana is much applicable for public environments where busy traffic is expected, for example in entries, shops and public toilets.
