Vevor fire glass adds a bright copper reflective look to fire pits, fireplaces, and other decorative spaces. Made from tempered glass and quartz sand, it is designed to handle high heat without cracking, darkening, smoking, or leaving ash behind. The crushed 1/4" pieces create a clean, modern flame display while helping conceal gas pipes in fire features. It is also suitable for decorative use in gardens and aquariums. The 10 lb bag offers an easy way to upgrade the look of your fire feature.
