To cut glass tiles safely, use a specific glass blade made with a uniform and fine diamond grain to ensure a clean cut. A glass blade also protects the tiles.
A set of tile nippers may also be necessary for cutting glass tiles. To avoid injury, wear protective goggles and gloves. Other safe ways of cutting glass tiles include a wheel cutter, which is ideal for cutting straight lines, and a mallet and hardie, which work well for thicker tiles. Wrap the tiles in a rag or an old T-shirt when using a mallet and hardie to avoid damage to the surface.
