These square tiles are made of opaque glass. They are shiny on one side and grooved on the other side to help with adhesion. They are 12mm x 12mm and they are 4mm thick. These can be used indoors and outdoors, as they are UVA and Frost proof. This sintered tile is made in a 100% green process using powdered recycled window glass and pigments.
These squares are a medium gray, and they have an iridescent finish created by dipping the tiles into acid to create a shimmering mother of pearl layer that is permanently bonded to the surface.
