Blazestone tiles are crafted entirely from post-industrial and post-consumer glass. No additional oxides or colourants are used. Each tile is handmade from combinations of glass that give the tiles their appearance and colour variation. Because the tiles are hand-made, there are slight differences in shape and variations in the surface. The tiles have been positively tested for wear and tear, scratch resistance and (thermal) shock. They may be used indoors as well as outdoors on both floors and walls.
