An extremely stylish mosaic glass tile collection that radiates sophistication in every one of over a dozen different color designs. Shining Series glass tiles use up to 59 percent post-consumer recycled glass that is enhanced by a permanent iridescent effect through the addition of semi-precious metals during production. This stunning iridescence is not affected by chemicals, temperature or even use. Each glass mosaic tile sheet is 12 7/16” x 12 7/16” with chips 3/4” x 3/4” and 4 mm thick.
