Add a bright, reflective accent to your fire feature with these Caribbean blue fire glass beads from Vevor. Made from standard fireproof glass derived from quartz sand, they are designed to handle high heat without cracking, darkening, smoking, or leaving ash behind. The flat round beads create an attractive flame display while also helping conceal gas pipes in fire pits. They are also suitable for decorative use in fireplaces, gardens, and aquariums. Easy cleaning with a water and vinegar rinse helps restore their shine.
