Harder than marble, Bonfire Glass Tiles are as durable as they are beautiful. Due to the non-porous nature of glass, Bonfire Glass Tiles are impervious to water and other elements. Therefore, our art glass tiles need no sealant to retain their stain-resistant qualities. To install art glass tiles, you can use the same tools and materials you would use for any tiling project, with slight variations in technique. Bonfire Glass Tiles are made from 90% post-industrial recycled materials using ecologically sound practices.
