Fire Pit Glass, Cobalt Blue, 10 lb, 1/2 in Reflective

Cobalt blue fire pit glass adds a clean, reflective flame bed while helping your gas fire feature look finished and modern. Made from tempered glass, these 1/2-inch crushed pieces sparkle in daylight and glow at night, concealing burner media and lines for a tidy presentation. Designed for high heat, it resists dulling and cracking under typical fire pit temperatures, and it rinses clean to restore shine.

• Delivers a vivid cobalt-blue shimmer that reflects flame for a brighter, more defined fire pit display.


• Handles high heat with tempered, impact-resistant crushed glass made for fireplaces and gas fire pits.


• Reduces mess versus wood by producing no ash and avoiding smoke or odor from the media itself.


• Fits fire pit tables and fireplaces; also works as decorative crushed glass for landscaping accents.


• Simplifies upkeep—rinse with a 1:1 water and vinegar mix, dry fully, and return to use.

Use this reflective crushed glass to cover burner areas, hide gas pipes, and create a polished look that elevates patios, decks, and outdoor living spaces. For best results, build a 2–4 inch layer to balance coverage and airflow, then keep an extra bag on hand for seasonal refreshes or new projects.
