Fire Pit Glass, Cobalt Blue Reflective 10 lb 1/4 Inch

Fire pit glass rocks add a clean, reflective flame bed while covering burner media for a polished, modern look. This 10 lb cobalt blue crushed tempered glass sparkles in daylight and glows under flame—without ash buildup. Made from high-temperature tempered glass produced from quartz sand, it’s designed to resist heat up to 1112°F / 600°C and maintain color clarity. Use in gas fire pits, fire tables, fireplaces, or as decorative landscaping accents.

Skip messy, sooty filler and upgrade your fire feature with reflective crushed glass that looks intentional in any outdoor or indoor setup. For a balanced mix of coverage and airflow, fill to a recommended 2–4 in depth, then adjust to your preferred flame height. The tempered construction is impact-resistant compared to standard glass and is built for repeated heating cycles. Refresh the look anytime with a quick rinse and let it dry completely before relighting. Grab yours today and finish your space with a crisp cobalt blue glow.
