Stanbroil Royal Cobalt Blue 1/2" Fire Glass Diamonds, 10 lb — Tempered, Jewel-Toned Sparkle

Stanbroil Royal Cobalt Blue 1/2-inch fire glass diamonds are premium tempered glass pieces designed to replace lava rock or gas logs and deliver long-lasting, jewel-toned sparkle for propane or natural gas fire features.

These 10-pound bags contain half-inch, diamond-cut fire glass in a vivid royal cobalt blue luster that keeps its color under heat. Each piece is tempered for durability and engineered to resist thermal shock, making it suitable for indoor and outdoor gas fireplaces, fire pits, and decorative fire bowls. The product is non-combustible, reusable, and intended as a decorative, heat-tolerant media for vented gas appliances and open-air fire features.

How will this fire glass change the look of my fire pit or fireplace?

Royal cobalt blue fire glass transforms flames into a sparkling, reflective bed that emphasizes color and clarity. Because each piece is cut to catch and reflect light, flames appear brighter and more visually striking without introducing soot or ash.

• Creates a high-gloss, jewel-like surface that intensifies flame color and shimmer
• Uniform 1/2" diamond pieces for consistent visual coverage and sparkle
• Cobalt blue luster adds a modern, vibrant accent to both indoor and outdoor settings

Is Stanbroil fire glass compatible with my gas appliance and how durable is it?

This tempered fire glass is manufactured for use with propane and natural gas systems and will not burn or degrade when used as directed. The premium tempering process reduces the risk of fracturing from heat cycles, so pieces retain color and shape through repeated use.

• Safe for propane and natural gas burners when installed per appliance instructions
• Tempered to withstand repeated heating and cooling without crumbling
• Non-combustible and does not emit residue like wood or lava rock

How do I install and keep this fire glass looking its best?

Installation is straightforward: remove any existing media, place the glass over the burner in a single even layer, and maintain proper burner clearance. Cleaning requires only occasional rinsing with vinegar and water to restore shine and remove dust or deposits.

• Install as a single, even layer—avoid burying burners or covering ports
• For cleaning, rinse with a mild vinegar-and-water solution and air dry
• Store leftover glass in a dry container to prevent dust buildup

Are there safety considerations I should know about?

While fire glass is non-combustible, correct installation and burner clearance are essential to safe operation. Always follow your fireplace or fire pit manufacturer's instructions and check that the burner ports remain unobstructed to avoid flame roll-out or uneven heating.

• Do not mix with combustible materials or place directly on wood-burning appliances
• Ensure burners and ports are clean and visible before use
• Allow glass to cool fully before handling or cleaning
