Vevor reflective crushed fire glass adds a bright copper finish to fire pits, fireplaces, and decorative displays. Made from tempered glass derived from quartz sand, it is designed to withstand high heat without cracking, darkening, smoking, or producing ash. The reflective 1/2" glass creates a sparkling flame effect while helping conceal gas pipes in fire pit installations. It is also suitable for decorative use in gardens and aquariums. The glass is easy to clean with a simple water and vinegar rinse.
