Glass Hardness Tile

Glass Hardness Tile – Mineral Hardness Testing Tool This glass hardness tile is a reliable tool for performing mineral hardness tests, helping determine whether a specimen can scratch glass—an important step in mineral identification. Designed specifically for hands-on geology work, this tile provides consistent results without the fragility of standard glass. Each tile measures 1.5" x 1.5" x 0.25" and is made to be durable and break-resistant, so it won’t shatter during normal testing. The rounded edges add an extra layer of safety, making it suitable for student use in classrooms, homeschool settings, and labs. It’s also tough enough to survive the occasional drop to the floor. This glass hardness tile is ideal for rock and mineral testing kits, Earth science labs, geology activities, and hands-on mineral identification, offering a safe and long-lasting alternative to traditional glass plates.
