Mr. Fireglass Crushed Fire Glass for Fire Pit 10 lb – High Luster Black, Tempered 0.79"–1"

Mr. Fireglass 10 lbs Crushed Fire Glass in high-luster black is tempered, decorative glass gravel designed to replace lava rock or ceramic media and create brighter, cleaner flames in gas fire pits and fireplaces.

This premium pack contains uniformly sized 0.79"–1" crushed tempered glass pieces engineered for high heat environments. The dark, mirror-like finish reflects flame light and hides soot, while the non-porous surface resists staining and is simple to rinse clean. Use it in outdoor fire bowls, built-in fire tables, or indoor fireplace installations where a modern, low-maintenance look is desired.

How does Mr. Fireglass improve my fire pit's flame appearance?

The crushed black glass enhances flame contrast and creates taller, more vibrant-looking flames by improving oxygen flow around the burner. Its polished surface reflects light for a sparkling effect that accentuates flicker and color.

• Uniform 0.79"–1" pieces promote steady airflow and flame height.
• Reflective black finish deepens visual contrast with orange flames.
• Even pieces help produce consistent, balanced flame patterns.

Is this fire glass safe for high temperatures and long-term use?

Yes—Mr. Fireglass is tempered to withstand extreme heat up to 1600°F without cracking or discoloring. Because the glass is non-porous and chemically stable, it won’t emit smoke or harmful residues when used with gas burners.

• Tempered glass resists thermal shock and breaking under heat.
• Rated to 1600°F for use around fireplaces and outdoor burners.
• Does not produce ash or chemical odors during normal operation.

How much glass do I need and how does the 10 lb bag perform?

A 10 lb bag covers a modest area and is best for topping smaller burners, bowls, or for mixing with other media. Coverage depends on burner size and desired depth; this pack offers an easy way to refresh appearance or test a new look before committing to larger quantities.

• 10 lbs is ideal for small fire bowls, portable units, or accent layers.
• Combine multiple bags for larger built-in fire tables or deep beds.
• Uniform sizing helps estimate coverage and maintain consistent depth.

How do I maintain and clean the crushed fire glass?

Maintenance is low: the glass is non-porous so it resists ash and soot buildup, and it can be quickly refreshed by rinsing with water. For deeper cleaning, remove the glass, wash in mild soap and water, then allow to dry before returning it to the burner.

• Routine rinse restores sparkle with minimal effort.
• Non-porous finish prevents long-term staining or odors.
• Inspect for foreign debris periodically to protect burners.

Who is this for: Mr. Fireglass 10 lbs Crushed High Luster Black is suited for homeowners, landscapers, and designers seeking a contemporary, low-maintenance fire media for gas fire pits, fire bowls, and indoor fireplaces. It’s a practical choice for anyone wanting improved flame visuals, easy upkeep, and a durable alternative to lava rock or ceramic logs.
