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 lovely chestnut brown color, 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. They are slightly darker than they appear in most of the photos. Please see the last photo for another view of the color.
